- 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.
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.
