- Technologies to rejuvenate old and senile orchards have been standardized for mango, guava and aonla.
- High density planting for mango cv. Dashehari with 400 plants ha -1 spaced at 5.0x5.0m and guava cv. Allahabad Safeda with 555 plants ha -1 spaced at 3.0x6.0m were standardized.
- Drip irrigation from September to second week of May followed by fertigation with P and K of 25 per cent of the recommended dose in split doses at flowering and fruit setting have given highest fruit yield ( 59.74 kg tree -1 ) in comparison to conventional (basin system 18.71 kg tree -1 ) irrigation and fertilizer use.
- Institute developed meadow orchard system for guava, which accommodates 5000 plants ha-1 (1.0m x 2.0m) coupled with regular topping and hedging. An average yield of 12.5 tonnes ha-1 was obtained after first year and it reached to 50 tonnes ha-1 after 3rd year.
- Institute developed a technique of rapid multiplication (Wedge grafting), which has a tremendous potential for multiplying guava plants rapidly throughout the year in greenhouse as well as in open conditions.
- Model nursery having a separate Nucleous scion bank, poly and net house facilities have been established for the multiplication of elite clones of mango, guava, aonla and bael.
- Cow dung pasting in rejuvenated mango trees is found most effective for the control of gummosis.
- Mango based cropping system has been developed and recommended by the Institute. Cowpea-potato system has been found to give high monetary returns up to 10 years of plantation.
- Soil application of 4g per tree of paclobutrazol (3.2 ml/metre of canopy diameter) has been found effective to induce regular flowering and fruiting and in controlling irregular bearing in mango cultivar Dashehari.
- Soil application of 1 kg N, 1 kg P 2 O 5 and 1 kg K 2 O per tree during July to 10 years old (grown-up) Dashehari mango tree increased the yield.
- 250g Azospyrillum with 40 kg FYM has been found effective in increasing yield of 15 years old mango cv. Dashehari.
- Farm waste utilization through NADEP, Vermi, micro mediated and Biodynamic (BD) compost have enhanced beneficial microorganisms in soil.
