Research Fields

Crop production

Inter-cropping: Inter-cropping of pigeon-pea with groundnut in 1:2 ratio improved the nodulation and nitrogen fixation and increased the net return and benefit cost ratio. The land equivalent ratio was increased in intercropping of pigeon-pea+ rice with 1: 5 ratio.

Jute: The tossa jute genotypes of  JRO-524, JRO-7835, KOM-65 and TJ-40 produced higher fibre yield than  all the white jute varieties. Sowing of tossa jute varieties of JRO-524 and JRO-878 in mid April  was tolerant to premature flowering and  enhanced fibre yield. The sowing of tossa jute in east west direction of sowing produced the highest fibre yield  and net return over the strip cropping of jute with some pulses and cereals. Sowing of tossa jute @ seed rate of 2 kg/ha with later wheel hoeing at 30 cm row distance produced maximum  fibre yield. Broadcast sowing of tossa jute @2 kg/ha with later wheel hoeing  in  30 cm apart at 15,20 and 35 days after sowing produced the higher  fibre yield than line sowing. The white jute sown with row distance of 30 cm with seed rate of 4 kg/ha remarkably augmented the fibre  yield . White jute sown during early April to mid May with spacing of 30 cm from row to row and 6-8 cm from plant to plant without clipping augmented the seed yield over tossa jute.

Nutrient Management

Rice- Application of phosphorus in equal proportion of mussori rock phosphate and single superphosphate at the dose of 80 - 40  - 40 kg NPK/ha increased the yield of rice in coastal alluvial soil of Orissa. 

Application of 60 kg N, 13 kg P and 25 kg K /ha produced maximum yield in salt tolerant  rice variety Lunisree.

In broadcast beushaned rice, application of all phosphorus at sowing, 50% NK at beushsning and    rest  50 % NK at panicle initiation  stage with ferilizer dose of 60 kg N,14 kg P and 25 kg K/ha recorded maximum yield and net profit .

In transplanted rice, use of 5 kg Zn/ha combined with lime @ 0.25 lime requirement reduced the iron toxicity and augmented the grain yield. Sulphur-95 applied  @ 40 kg S/ha enhanced the grain yield of rice in red lateritic soil of Orissa.

Application of recommended dose of fertilizer  combined  with 5 kg zinc/ha through zinc sulphate @ 25 kg /ha and Boron @ 1 kg/ ha produced the highest grain and straw yield along with net return and benefit cost ratio in transplanted rice.

Groundnut- Application of recommended dose of fertilizer(20-40-40 kg NPK/ha) with 5 kg zinc+ 1 kg B + 0.5 kg Mo/ha increased the pod yield of ground nut.

Ricebean- Significant increase in nodulation, dry matter production  and seed yield in varieties of K-7, K-11 and BC-15 was observed with increase in phosphorus dose at 60 kg/ha .

WhiteJute-  White jute responded well  to increase level of N up to @ 80 kg/ha. At this   dose of nitrogen, fibre yield and net return was augmented the with less incidence of pest and diseases.

The capsuris jute performed well with application of water hyacinth compost @ 5 t/ha with 40-20-20 kg NPK/ha.

Tossa Jute -The tossa jute varieties of JRO-524 (Naveen) and KOM-62 (Rebati) fertilized with at N dose at 60 kg/ha increased the fibre yield. The tossa jute variety JRO-524(Naveen) gave better performance at reduced level of nitrogen than other varieties.

Tomato- Application of recommended dose of NPK in conjunction with 10 t vermicompost and  1 kg boron /ha produced the  highest fruit yield.

Forage crop-   Application of 50 % recommended dose of fertilizer i.e.10-40-20 kg NPK/ha combined with  poultry manure @ 2.5 t/ha and S @ 40 kg/ha  at sowing enhanced the forage yield of berseem .

Cropping System:

Application of water hyacinth compost @ 5 t/ha with 40-20 kg NP/ha to white jute increased the fibre yield and yield of rice and blackgram when grown with carry over effect  of white jute  in jute �rice �blackgram cropping system.

 Application of 40-20-20 kg NPK/ha integrated with FYM @10 t /ha to tossa jute  increased the  fibre yield and the seed yield of mustard when grown  under residual fertility condition in jute-mustard sequence.

Weed management

Rice- Direct seeding of rice with 20% excess seed rate and pre emergence application of butachlor @ 1.0 kg/ha with one inter cultivation and hand weeding at 4 weeks crop age reduced weed competition and increased the  weed control efficiency , grain yield and economics in  rainfed upland ecosystem.   Pre emergence application of bensulfuron methyl @ 120 g/ha at 3 days after transplanting reduced   the weed density and dry matter accumulation and increased the weed control efficiency along with yield and economics.

Wheat- Pendimethalin applied @ 1.0 kg/ha as pre emergence spray at 1 day after sowing depressed the weed  density and dry weight and  enhanced the weed control efficiency , yield and economics.

Groundnut- Use of napropamide @ 1.5 kg/ha at 1 day after sowing as pre emergence spray reduced the weed competition and augmented the weed control efficiency, pod yield and economics.

Soybean- The herbicide combination of kloben @ 13.5 g/ha and pantera @ 60 g/ha as post emergence spray  at 15 day after sowing registered the highest weed control efficiency and seed yield followed by pre emergence application of alachlor @ 1.0  at 1 day after sowing .

Cotton- Pre emergence application of pendimethalin @ 1.0 kg/ha at 1 day after sowing with sequential application of quizalofop-p-ethyl @ 50 g/ha supplemented with one hoeing at 45 days after sowing recorded the maximum seed cotton yield , net monetary return  and benefit cost ratio .

Jute- Pre plant incorporation of fluchloralin @ 1 kg/ha at 3 days before sowing supplemented with manual weeding at 35 days after sowing increased the fibre yield and eonomics of white jute. Pre emergence application of pendimethalin @ 0.75 kg/ha was effective to control monocot and dicot weeds along with better yield performance in tossa jute.

Tomato- Pre emergence application napropamide @ 1.5 kg/ha at 3 days after   transplanting increased the fruit yield and net profit .

Plant protection

Rice- The pre emergence application of pendimethalin @ 1 kg/ha at 3 days after transplanting  with recommended  60-30-30 kg NPK/ha and spraying of monocrotophos @ 0.02% were effective for control of pest complex in rice and  found augmenting the yield of lowland transplanted rice.

Seedling root deep of rice with [email protected] 0.02% followed by granular application of  ethorophos @ 1.0 kg a.i./ha at  30 days after transplanting were effective  to control gall midge and observed safe for gall midge parasite.

Jute- The white jute sown on 5th May with row spacing of 30 cm with out clipping recorded higher seed  yield than tossa jute with least occurrence of pest and diseases.

The application of recommended dose of fertilizer (40-20-20 kg NPK/ha) was advantageous  in significant reduction of pest and diseases over    recommended dose of fertilizer combined  with  10 kg Zinc and  2.5 kg Boron/ha when applied to tossa jute .

Application of 20 kg N/ha with  inoculation of Azospillum brassilence @ 5g/kg of seeds reduced the incidence of stem rot and root rot diseases and improved the fibre yield of tossa jute  which remained at par with higher doses of nitrogen.
