RESEARCH ACHIEVEMENTS
CROP SCIENCE
RICE
The higher grain yield in ICM was mainly due to a higher number of panicles/sq. Tricyclazole was found significantly effective in controlling blast severity and increasing grain yield over untreated control (Table 7).
MAIZE
New insecticide molecules Rynaxypyr 04% G and Rynsxypure 20 SC were evaluated against rice stem borer, rice leafhopper and rice root aphid. Rynaxypyr 04% G @ 3 g a.i./ha and Rynsxypure 20 SC @ 30 ml a.i./ha were found significantly effective in controlling rice stem borer, rice leaf folder and rice root aphid.
PULSES
Another set was maintained in the medium of the same composition but with 1/10th concentration of silver nitrate. It was also necessary to reduce silver nitrate concentration to 1/10th in the ripening medium.
OILSEED CROP
Pod borer Helicoverpa armigera, cutworm Agrotis ipsilon and leafminer and semilooper were observed as the major lepidopteran pests of gram and pea, respectively.
CROPPING SYSTEMS
Adoption of different crops was found to have a significant effect on rice grain yield (Table 1). The highest rice yield (5.28 t/ha) was observed with rice-fish-Azolla feeding system followed by rice-fish-Azolla (Table 3)a.
ORGANIC FARMING
Lowland rice varieties also recorded higher yield in integrated management practices followed by organic management practices (Table 8). An improvement in soil fertility status under different management practices was observed compared to the initial status (Table 9).
OILSEEDS
The formulations, GF2, RCHF 22 were found promising in increasing the yield of turmeric rhizome and it was higher by 44%. The maximum activity of these four foliar feeders occurred during the 3rd to 8th week after crop emergence.
SOIL SCIENCE
- Physical
- Chemical
- Soil fertility
- Biological
- Miscellaneous parameter which will be estimated based on the tests carried outs
The use of zinc and boron in combination with both sources of N and P fertilizers increased yield. The influence of different sources of nitrogen and phosphorus as well as boron and zinc on the soil.
FRUITS
Meghalaya purple, Nagaland purple, Kerala yellow, RCPS-1, Panama yellow, DPI, EC-1 and EC-2 were evaluated for fruit yield and physicochemical parameters of three-year-old plants. Physico-chemical characteristics of passion fruit showed great variation in fruit weight, size, juice % and quality attributes such as TSS, acidity, ascorbic acid and sugars due to genotypes of different species.
VEGETABLES
The toxicity of two new 'reduced risk' insecticides, novaluron 10 EC and spinosad 2.5 SC, was evaluated against different instars of the cabbage moth, Pieris brassica, and first instar larvae were found to be the most susceptible, with dose-dependent mortality , was observed with both new insecticides. The powder of pine needles, tithonia leaves, jamardoh leaves in three doses (0.5, 1 and 1.5 g/kg soil) and carbofuran (16.5 mg/kg) as a standard test were evaluated against M.

POST HARVEST MANAGEMENT
The grain samples collected during surveys were analyzed for incidence and incidence of insect pests on different commodities of paddy, maize and pulses with in a period of 2-3 weeks of collection. Results revealed that various insect pests are associated with these commodities and their occurrence and abundance were relatively different in different commodities (Table 2).

AGROFORESTRY
In the third year of experimentation, the highest average yield of pineapple was recorded in the understory of G. Maximum plant height (215 cm) and maximum number of primary branches (2.33/plant) were recorded with Kanpokpi.
AGRICULTURAL ECONOMICS
Cattle productivity in terms of milk yield has been estimated to be significantly higher due to the anthelmintic treatment of cattle. The regression coefficient for green fodder was 0.196 and was significant at the 5 percent level of significance.
ANIP ON RODENT CONTROL
The IRR has been estimated to be 31%, which is greater than the discount rate (12%), therefore favoring the investment in the construction of Jalkund. Hence all the investment criteria namely IRR, NPV and BCR were found favorable for investment in the construction of Jalkund.

About 1610 healthy seedlings per m2 of the brinjal variety were obtained in the polyhouse, while from open area 1220 healthy seedlings per m2 were obtained, recording a survival percentage of 24% more inside the polyhouse. Tomato seedlings of Rocky variety were sown in the polyhouse in the last week of June.
