Postgraduate classes in Horticulture were initiated in 1945 under the administrative control of Professor Agri. Botany with one Asstt. Professor, one lecturer, and one Demonstrator. In 1960 separate Department of Horticulture was created with 13 acres of Garden for practical purpose. In 1962, a one-hectare area was allotted for nursery for practical training of students, latter on one-hectare more allotted for nursery purpose.
College of Horticulture came into existence by the permission of Honbâle Governor of U.P. vide his letter no. E-7773/G.S. dt. 22.09.2010 under the university act chapter-V, 28 (i) and chapter-VI, 17(i)(2) & (3), section 28(b) and subsequently by the notification of university registrar no CSUR/2314/2010 dt. 26.10.2010 with two departments viz., Department of Fruit Science and Department of Vegetable Science.
I. Department of Vegetable Science
II. Department of Fruit Science
The major activity of the department is teaching courses related to fruit production, floriculture, and post-harvest management to the students of B.Sc. Ag., B.Sc. Hort., M.Sc. Hort. and Ph.D. F.Sc. and conduct research to improve production, productivity, and quality of different fruit crops.
In the department, every year10 students in a master’s degree and 4-5 students in the doctoral degree program were admitted. Presently the department has 13 acres of Garden of different blocks of fruits viz., mango, guava, litchi, sapota, pomegranate, aonla, ber, phalsa, citrus fruits, jackfruit, jamun, etc., flowers (rose, tuberose, etc.) and ornamental plants for practical purposes and two acres areas under nursery for practical training of students.

RESEARCH RECOMMENDATIONS:
The research achievements of the Department are as follows-
- Propagation techniques have been standardized in a number of fruit crops viz., Mango, Guava, Litchi, Lime, Lemon, Jackfruit, Peach, Ber, Aonla, etc.
- Standardized dose of plant bio-regulators in strawberry, phalsa, litchi, citrus, guava, mango, etc.
- The dose of bio-fertilizers in various fruits such as strawberry, banana, etc. and micro-nutrients in guava, mango, aonla, strawberry, phalsa, litchi, etc. had been standardized.
- Time and method of pruning in guava, phalsa, jack fruit, mango, ber, litchi, etc., had been standardized.
- Salt tolerance studies have been conducted on several fruits viz., Mango, Guava, Ber, Grape, Aonla, Jamun, Pomegranate, Bael, etc., which help in selecting salt-tolerant strains according to the need of the orchardists.
Aonla:
Pollination study:
In aonla cultivars, Banarasi proved a good pollinizer for cv. Francis and vice versa. Therefore, both these vars need to be planted together in an orchard.
Increased fruit size with superior quality of fruits for consumer acceptability and processing industry
- For this purpose, fruits of aonla should be bigger, more pulpy with a small stone, high TSS, and ascorbic acid content. The pre-harvest application of calcium nitrate @ 1.5 percent also increased fruit weight, the volume of fruit, pulp weight, and reduced stone weight. The calcium nitrate @ 1.5 percent also increased the TSS, total sugar, and ascorbic acid and reduced the titratable acidity content of fruits as compared to control. This technology has been applied in aonla orchard in a village which has earned growers appreciating for a higher economic yield of quality fruits.
- In aonla cv. NA-7 treatment with a higher concentration of Borax 0.6% significantly reduced fruit drop and increases fruit retention. Spraying of GA3 at 100ppm resulted in maximum fruit yield (81.86 kg/plant), increased fruit length, width, weight, volume, specific gravity, pulp weight, pulp stone ratio, fruit moisture, ascorbic acid, TSS, and total sugars, and reduces stone weight, titratable acidity.
- To obtain significantly reduced fruit drop and increases fruit retention with maximum fruit yield (81.25 kg/plant), increased fruit length, width, weight, volume, specific gravity, pulp weight, and maximum pulp stone ratio in aonla cv. NA-7, plants should be sprayed with a higher concentration of NAA (20ppm) and GA3 (40ppm).
- To obtain reduced fruit drop and increases fruit retention along with higher yield with more specific gravity, more length, width, weight and volume, pulp weight, pulp: stone ratio, moisture, total sugars, and TSS Brix contents in fruits, plants of aonla cv. NA-7 should be sprayed with GA3 @ 100ppm and borax at 0.6 in August in the north Indian plains.
- In aonla cv. NA-7 treatment with a higher concentration of Borax 0.6% significantly reduced fruit drop and increases fruit retention. Spraying of GA3 at 100ppm resulted in maximum fruit yield, increased fruit length, width, weight, volume, specific gravity, pulp weight, maximum pulp stone ratio, fruit moisture and reduces stone weight. Plant treated with GA3 @ 100ppm also results in an increase in ascorbic acid content and reduced (minimum) titratable acidity. Similarly, GA3 @ 100ppm significantly increase TSS (15.10°Brix) and total sugars (12.75%) content in fruits of Aonla.
- To obtain reduced fruit drop and increases fruit retention along with higher yield with more specific gravity, more length, width, weight and volume, pulp weight, pulp: stone ratio, moisture, total sugars, and TSS ‘Brix contents in fruits, plants of aonla cv. NA-7 should be sprayed with zinc sulphate and borax each @ 0.6 % in August in the north Indian plains of U.P.
- To obtain higher yield with increased fruit length, fruit width, fruit weight, fruit volume, specific gravity, pulp weight, and maximum pulp stone ratio, plants of aonla cv. NA7 should be sprayed with NAA at 20ppm and borax @ 0.4 % in August in the north Indian plains of U.P.
Increase in storage life:
- In an experiment conducted on the effect of calcium chloride and calcium nitrate on Physico-chemical composition and shelf-life of aonla cv. Banarasi revealed the effectiveness of 1.5% calcium nitrate which improved Physico-chemical composition as compared to control and other treatments. The maximum PLW (%) and spoilage (%) and maximum TSS. ascorbic acid and minimum acidity were observed under 1.5 percent calcium nitrate pre-harvest spray treatment.
- Physio-chemical composition of two aonla varieties indicated variability in most of the characters and, in general, Banarasi exhibited superiority for processing over Krishna the recipes and techniques for preparation of value-added products viz., jam, syrup, candy, and preserve were standardized to utilize the fruit for processing.
Banana:
Fixing maturity standards and development of uniform ripening techniques, other than carbide for the longer shelf life of Harichhal banana
- For optimal maturity index banana should be harvest at 15-week-old shooting age when ridges on the banana fruits become flattened but visible.
- Uniform ripening in three days can be obtained by dipping banana bunches in ethrel 800 ppm solution in warm water for the 5-minute duration in the ambient condition.
- Dipping banana bunches in GA3 150 ppm for 30 seconds enhances the green stage (delayed ripening by 3-4 days at ambient condition.
- By post-harvest dip of banana bunches in 2,4,5-T @ 25ppm solution for 30 seconds, shelf life can be increased up to 10 days
- For long-distance transportation or long-term storage, banana can be stored under 13°C for up to 25 30 days.
- Fungicide benlate @ 500 ppm treated banana packed in 200-gauge unvented polythene packets can be kept up to 10-12 days in ambient condition and up to 25-27 days in 13°C storage condition.
- Fungicide benlate 500 ppm treated banana covered with 200 gauge vented polythene packets can be kept up to 6-7 days in ambient condition and up to 15 days in 13°C storage condition with enhanced quality.
Increase in the yield and quality of tissue cultured banana:
- Technology developed through INM for getting the maximum yield and superior quality of tissue cultured banana cv. Grand Naine. The application of 100% RDF of NPK (50 kg N + 25 kg P+25 kg K) + 50g Azospirillum + 50g PSB + 50g Trichoderma harzianum per plant at the time of planting resulted in earliness in flowering and flowering to the harvesting of the bunch as compared to others. Maximum bunch weight, number of fingers per hand and bunch, finger weight, length, diameter, TSS, total sugars, pulp percentage and pulp: peel ratio with reduced peel percentage and titratable acidity have also been recorded. The technology has been narrated to the banana growers.
- Tissue cultured plants of banana cv. Grand Naine fertilized with 100%RDF of NPK+50g Azosrollium + 50g + 50g PSB + 50g Trichoderma per plant significantly increased pseudo-stem height, number of functional leaves with reduced days taken for bunch initiation, days taken from bunch initiation to harvest. The same treatment also produced higher bunch weight, more number of fingers per hand, more number of hands/bunch and more yield/ha.
- To obtain maximum girth of pseudostem, number of leaves per plant, the maximum length of inflorescence, number of fingers per hand and bunch, finger length, weight, diameter, total soluble solids, total sugars, pulp and pulp: peel ratio with the minimum amount of titratable acidity and peel, first-year ratoon banana crop (tissue culture banana) cv. Grand Naine should be treated with 100% RDF of NPK+50g Azospirillum+50g PSB+50g Trichoderma harzianum.
Increase in the yield and quality of vegetatively propagated banana:
- In a nutritional trial on banana var. Dwarf Cavendish, it was concluded that application of 10 kg FYM+250N + 300g P+250g K/plant maximized the height, no. of leaves, and weight of bunch plant.
- In banana cv. Dwarf Cavendish three spray of micro-nutrients mixture at 1% was significantly effective to increase TSS, total sugars, reducing sugar, and non-reducing sugar content. The maximum size of the mature finger was also obtained with three sprays of 1% micronutrient mixture. Weight of mature finger, the weight of ripe finger, pulp peel ratio, and Vitamin C were significantly increased with 60ppm of IAA solution.
Strawberry:
Plant bio-regulators promote berries yield and quality:
- Plants treated with GA3 @ 100ppm before the flower bud initiation stage, i.e., 65 days after transplanting produced the tallest plants with the higher number of leaves and flowers. It also extended the duration of flowering, resulted in higher yield per plant having maximum length, and weight of berries also inducing earliness. On the other hand, the application of Cycocel (CCC) at 1000 ppm exhibited maximum fruit width, total soluble solids, total sugars, and ascorbic acid contents. The technology has also been demonstrated in the farmerâs field inducing some farmers to adopt the technology for strawberry production.
- For getting a good yield of quality fruits of strawberry cv. Sweet Charlie the plants should be sprayed with GA3 and BA each at 100 ppm one month after planting in northern (Uttar Pradesh) India.
Biofertilizers promote berries yield and quality:
- For getting berries with maximum length, width, weight, volume, TSS, total sugars, ascorbic acid with minimum titratable acidity with the higher number of crowns, number of runners per plant, plants should be supplied with Azotobacter at 7 kg/ha + vermicompost at 30 tonnes/ha under plains of central Uttar Pradesh (India).
- In strawberry cv. Chandler, application of Azotobacter at 7 kg/ha resulted in better growth and a higher yield of quality berries with more propagating materials.
Micronutrients and mulching promote berries yield and quality:
- In strawberry cv. Chandler foliar spray of 0.4% ZnSO4 proved most effective in improving yield and quality characters.
- In a mulching trial conducted on strawberry cv. Sweet Charlie, the polyethylene mulch was found to be the best mulching material with respect to growth, fruiting, yield and quality parameters.
- Also, use of black polythene mulch and 20th October planting proved the most effective treatments with respect to growth, flowering, fruiting, yield and quality of fruits.
Mango:
Mango malformation:
Foliar application of 200 ppm of NAA in mid-October alone or followed by De blossoming is very effective in reducing mango malformation.
Increase in the fruit retention, yield, and quality of mango:
- To obtain significantly reduced fruit drop and increases fruit retention with maximum fruit yield (54.70kg/tree), increased fruit length, width, weight, volume, specific gravity, pulp percent, total soluble solids, total sugars, ascorbic acid content with a decrease in the peel, stone percent and titratable acidity contents, mango cv. Dashehari plants should be sprayed with the combined application of GA3 (60ppm) + ZnSO4 (1.0%) in March under north India.
- To obtain significantly reduced fruit drop and increases fruit retention with maximum fruit yield (54.70kg/tree), increased fruit length, width, weight, volume, specific gravity, pulp percent, total soluble solids, total sugars, ascorbic acid content with a decrease in the peel, stone percent and titratable acidity contents, mango cv. Amrapali, plants should be sprayed with combined application of GA3 (50ppm) + NAA (40ppm) in the month of March under north India.
CITRUS PROPAGATION:
Citrus:
A study conducted on the effect of INM on growth and yield of Coriander as intercrop in citrus revealed a significant increase in yield (18.50g/ha) with the application of 25% RDF+FYM 10t/ha + Azospirillum + VAM followed by 25% RDF-FYM (17.00q/ha).
Sweet lime:
- In a propagational trial, sweet lime stem cuttings treated with IBA 1500 ppm + PHB 1000 ppm exhibited improved shoot and root development as well as success and survival percent.
- Wounding + 1500 ppm IBA found significantly most effective in causing earliest sprouting, vegetative and root growth of stem cutting in lemon var. Pant lemon -1.
- For obtaining maximum unique newly plant for plantation of sweet lime through stem cutting, cuttings should be treated with IBA 200ppm for early sprouting, increased in the number of sprouts, the diameter of sprouts and percentage of rooted cuttings.
- Genetically pure newly plants of Kagzi lime can be obtained through stem cutting with the treatment of IBA 3000 ppm + NAA 3000 ppm.
Cape gooseberry:
Increase in the growth, yield, and quality of cape gooseberry:
Application of vermicompost 2t/ha + 75% RDF significantly increased plant height, plant spread, number of leaves per plant, No. of branches per plant, No. of fruit per /plant, fruit weight, and yield per plant. So as far as quality characters are concerned application of vermicompost 2t/ha + 75% RDF also significantly increased TSS, ascorbic acid and reduced acidity content in cape gooseberry.
Phalsa (Yield and Quality):
- In phalsa cv. Sharbati, spraying of GA3 at 50 ppm increased yield and quality parameters and Ethrel at 1000 ppm resulted in early and uniform maturity.
- In Phalsa, all the growth, yield, and quality characters of phalsa significantly increased under paddy straw mulches followed by sugar cane trash except acidity compared with control.
- In phalsa, application of GA3 at 60ppm increased the average length of shoot, fruit set and yield of phalsa fruits. Application of 500ppm and 1000ppm ethereal caused maximum number of leaves/bush, shorter harvest span, the diameter of berry. TSS, maximum sugar content, and producing less acidic fruits.
- Spraying of Boron 40 ppm+GA3 30ppm is found very effective for improving yield for enhancing economy and prosperity of phalsa in the country.
- Application of 500 ppm and 1000 ppm Ethrel caused the maximum number of leaves, length of leaves, width of leaves, fruit set, diameter of berry, fruit weight, TSS, yield and application of 250ppm ethrel results in maximizing ascorbic acid and sugar content and producing less acidic fruits.
- Foliar sprays of Boron 50 ppm+GA3 30ppm brought about significant changes in the plant metabolism improving size, weight and quality of phalsa fruits. So growers may safely adopt the application of Boron 50 ppm+GA3 30ppm for increased yield of quality fruits of phalsa under North-Gangetic plains of India.
Phalsa (Pruning Effect):
- Plants pruned at 40.00 cm from the ground level on 15 Dec. proved most effective in improving vegetative growth, bud sprouting, the number of leaves and all other quality parameters like TSS, sugar, ascorbic acid content, fruit size and yield, while less acidity and less internodal length were also recorded under the same treatment.
Peach:
Propagation of peach through hardwood stem cuttings:
Peaches are commercially propagated either by budding or grafting. However, the production cost of such plants is quite high while the multiplication of plants by cutting is simple, cheap and rapid. To develop this technology, the cuttings (20 x 25cm) were treated with IBA 2000 + PHB 1000 + B50 ppm which exhibited early sprouting, higher sprouting percentage and more diameter of sprouts, increased number of leaves and roots with longest and thickest size, more root formation zone, best rooting and survival percentage. The farmers/ growers have visited the field in the department.

The farmers/ growers have visited the field in the department.
Influence of severity and time of pruning:
-
- Pruning study conducted on young subtropical peach plants cv. Saharanpur Prabhat revealed that it should be lightly pruned (15 buds/shoot) in early January for better results with respect to flowering, fruiting, and yield.
- An experiment conducted to see the effect of extent and time of pruning in peach revealed that the plants pruned on 5 February retaining 10 buds/shoot exhibited numerically greater size and weight of fruit.
- In case of peach 15 bud/shoot pruning at 15 Dec. to 1st Jan pruning treatment proved most effective with respect to flowering, fruiting, and yield of fruits of young-bearing plants cv. Saharanpur Prabhat.
Increase in fruit retention, yield and quality:
-
- The application of a pre-harvest spray of zinc sulphate at 0.4 percent 25 days before harvest proved most effective for improving the quality at harvest and storage period to maximize the shelf life of fruit.
- The pre-harvest spray of calcium nitrate at 10 percent, 20 days before harvest proved most effective for improving the quality and harvest und during the storage period and for maximizing the shelf life of peach fruits.
Litchi:
-
- In litchi foliar application of zinc cine sulphate (0.5%) improved fruit size, fruit weight, pulp weight, pulp: stone ratio, yield, and organoleptic rating. The fruit cracking was minimized by foliar application of Boron (Borax, 0.4%) while application of NAA (25ppm) exhibited minimum fruit drop.
- In two years, trial with litchi, application of organic manure (FYM 30 kg + poultry manure 10 kg + vermicompost 5 kg + neem cake 3 kg/tree) significantly increased the panicle length, percentage of fruit set, fruit yield, and TSS. However, there was no significant effect on the duration of flowering and fruit size further treatments of fruits with 6 per cent wax emulsion and packing in perforated LDPE bags reduced weight loss, spoilage and respiration rate.
- Pre-harvest spray of Ca (NO)2 at 2.0 % proved effective in maintaining must quality and plunging in litchi fruits during storage at ambient conditions. It minimized PLW and spoilage losses
- Combined application of NAA at 20 ppm and zinc sulphate at 0.6 % proved most effective in increasing fruit set, fruit size, weight, fruit yield, TSS and total sugar content of the cv. Calcuttia.
INM in Ber:
- In ber, application of 1000g N +500g P +250g K + 50 kg FYM promoted vegetative growth attributes significantly i.e., no. and length of shoots, no. of secondary and tertiary shoots, flowering and fruiting parameters, days to flower initiation, duration of blossoming and fruit development period were also recorded longer. When the NPK dose was slightly reduced keeping FYM stable fruit set, their retention, size, and weight of fruit were augmented significantly superior. The plants under control expressed significantly poor vegetative growth, flowering, and fruiting parameters, quality attributes, yield and yield components.
Guava:
Crop Regulation:
To get heavy and quality winter crop of guava and to avoid rainy season crop, a spray of 16.00 percent urea or shoot pruning (upper 30 cm part) in Ist week of May proved useful.
Shelf-life:
Pre-harvest spraying of Zinc slphate at 0.4 % 25 days before harvest proved most effective for improving quality and the shelf life of guava fruits cv. Sardar.
Rejuvenation and canopy management:
Experiment on Rejuvenation and canopy management in guava indicated that 40% of pruning produced the tallest plants (6.35 mt.). Canopy both E-W and N-S were also significantly greater under this treatment. Significantly heavier fruits and yield/plant were produced under 40% pruning and fruits have higher TSS, total sugar, and vit. C content with lower acidity.
Studies on etiology and management of guava wilt and identification of resistant rootstock.
- To solve the problem of guava wilt, a survey was made in Kanpur and surrounding districts. It was observed that the maximum severity of the disease was found in district Kannauj (30.14% followed by 18.33% in Farrukhabad). Fusarium oxysporum was found responsible for it.
- 20 gm Aspergillus niger (Pusa mrida) as well as Trichoderma viride mixed with 20 kg FYM per plant, applied in July has been found effective against the disease
- In July, application of slacked lime (1.80 kg) in Ganga Katri and Zypsum (3.0 kg) per tree in uplands at root level was found to be effective to minimize the disease.
- Psidium friedrichsthalianum has been found resistant to wilt.
- Linseed as an intercrop with guava was found to be effective to minimize the disease.
- For Newly planted plants of guava NPK, 50:20:40 gram per plant was found to be the best in terms of growth parameters.
- In existing orchards for fruiting trees, NPK @ 400:160:320 g along with 50 kg FYM and 0.5% micronutrients (Zn, B, Cu and Mn) per plant was found most effective in controlling the wilt disease.
- Biological control revealed that 20g Aspergillus niger (Pusa Mrida) as well as Trichoderma viride mixed with 20 Kg. FYM per plant was effective. Further, Psidium fridrichathalianum was found resistant to root-stock against the wilt.
Post-harvest:
- A study on the processing and storage of ginger beverages revealed that the rhizome of Pahari ginger can be very well used for producing quality beverages like RTS, squash, and syrup and these products may have excellent marketing potential because of their reasonably longer shelf life.
- In tomato cv. Angoorlata proved to be best for colour retention in prepared juice and the use of sodium benzoate was found to be superior as a preservative.
