Conservation of Genetic Resources:

(i) A total of seven hundred forty seven accessions including were introduced from eight different countries. The important accessions introduced were maize lines resistant to stem borer especially fall army worm (EC977839-977867) from CIMMYT, Mexico and improved cultivars with high TSS in Kiwifruit from USA (EC977548-977574).

(ii) A total of nine hundred forty four samples of imported exotic germplasm were processed for quarantine clearance and released to indenters. Stenocarpella maydis on Zea mays imported from USA was an important pathogen interception. For export, 10474 samples were processed for quarantine clearance and 10468 samples were released. Seven phytosanitary certificates were issued.

(iii) A fish species, red cornet (Fistula riapetimba) from inland waters of Cauvery estuarine mouth at Poompuhar was recorded for the first time.

Natural Resource Management:

(i) Developed organic farming package of practice of Scented rice – vegetable pea- sorghum (fodder) system at Jabalpur (Madhya Pradesh).

(ii) At Palampur, strawberry crop grown under protected cultivation with drip fertigation at 0.6 PE (Pan Evaporation) and 75% NK resulted in fruit yield of 381.97 g/m2 with 25% saving of NK and 40% water saving compared to crop fertigated at 1.0 PE and 100% NK.

(iii) Identified a three tier silvopastoral system comprising of mulberry/calliandra plus hybrid Napier plus stylosanthes/desmanthus to cater the fodder demands of small scale farmers of Kerala for profitable milk production.

(iv) Severe incidence of thrips was recorded and agro-advisory issued for the management of thrips for the benefit of mango growers/ stake holders in Uttar Pradesh.

(v) A botanical pesticide i.e. Prabal (Opuntia sp. + Oryza sativa) @ 0.1% was observed promising against wet bubble disease of mushroom under field conditions.

Development of Farm Implements, Machinery and Post – Harvest:

(i) Developed automatic control system for tractor implements combination.

(ii) Developed tractor operated intra row-cum-inter row weeder for orchards.

(iii) Developed seed metering mechanism for high speed seeding or planting.

(iv) Developed improve flaking system for small scale production of rice flakes.

(v) Developed tractor cabin using the criteria of optimum space layout for improvement of visibility of operators.

(vi) Developed a solar-powered cooler for storage of fresh fish at chilled temperatures of 1-30C in retail markets. Electric power generated by solar panels is stored in a battery which in turn supplies power to the cooler. The cooler can hold up to 50 kg of fish.

(vii) Developed fruit waste and plant extracts in developing antimicrobial coatings for extending shelf-life of fruits followed by clove oil and grapefruit oil.

(viii) Developed conductive yarn using core yarn spinning machine.

(ix) Developed spore based kit for detection of antibiotic residues in milk at dairy farm.

(x) Technology of sour dahi preparation using prolific acidifying lactic cultures was developed.

(xi) Technology for Misti Doi with fast acidifying high sugar tolerating lactic culture(s) was developed.

(xii) A fortified health drink with 10% Oyster mushroom, malted ragi flour, whey protein powder, milk powder, sugar & cocoa with overall good acceptability score was prepared.

(xiii) Process technology for Palada Payasam mix preparation by dry crystallization method in a mechanical unit was developed.
