Data from a field experiment on Real Time Nitrogen Management (RTNM) in rice revealed that variety Gobinda produced significantly the highest grain yield of 49.6 q ha-1 associated with long panicle (26.75 cm) bearing significantly the maximum number of filled grains panicle-1 (156.78) producing highest net return (Rs.33214.71), B-C ratio (1.83) and return per rupee invested (0.83). Application of nitrogen based on LCC threshold value 4 produced significantly the highest grain (52.6 q ha-1), straw yield (64.4 q ha-1), number of EBT m-2 (403.71), panicle length (25.43 cm) and 148.94 filled grain panicle-1. Variety x RTNM interaction was significant and variety Naveen and Gobinda produced significantly the highest yield of 55.4 and 58.2 q ha-1 at recommended of nitrogen whereas, Lalat and Hiranmayee responded to LCC threshold value 4 (N4) with grain yield of 50.4 and 52.1 q ha-1, respectively.

Transplanted Rice

A two years field experiment was carried out in sandy loam soil during rainy (Kharif) seasons in 2019-2020 at CRC farm of sardar vallabhbhai patel university of agricultural & technology, Meerut, Uttar Pradesh to evaluate the various Planting techniques and integrated nutrient management on yield and soil health of rice (Oryza sativa L.) under rice- wheat copping system. The treatments comprised of two Planting techniques i.e., E1-Conventional puddled transplanted rice (CT- TPR), E2- Wide bed Transplanted rice (W Bed-TPR) and Nine Nutrient management practices {N1- Control, N2- 100% RDF + ZnSO4 25 kg ha-1, N3- 125% RDN + ZnSO4 25 kg ha-1, N4- STCR based NPK application + ZnSO4 25 kg ha-1, N5- N2+ FYM  (5 t ha-1), N6- N2+ FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1, N7- 75% RDN + FYM (5 t ha-1) + ZnSO4 25 kg ha-1, N8-75% RDN + FYM (5 t ha-1) + PSB (5 kg ha-1) + Azotobactor 20 kg ha-1 +  ZnSO4 25 kg ha-1, N9- Organics Practices @ FYM (30 t ha-1)+PSB (5 kg ha-1) + Azotobactor 20 kg ha-1 + ZnSO4 25 kg ha-1} are laid down in Factorial Randomized block design and replicated thrice. The results indicated that among the different Planting techniques (PTs), conventional puddled transplanted rice (E1, CT-TPR) was recorded significantly higher grain yield (40.4 & 41.3 q ha-1), straw yield (62.7 & 63.8  q ha-1), NPK content and uptake and also improved soil health status ie., available NPK, organic carbon and other physical properties i.e, Bulk density, EC, pH  in soil than wide bed transplanted rice (E2, W Bed-TPR) during both years of kharif 2019 & 2020 respectively. Among the nutrient management practices, the N6 (100% RDF + ZnSO4 25 kg ha-1 + FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1 ) treatment produced significantly higher grain yield (49.0 & 50.2 q ha-1), straw yield (81.2 & 82.8 q ha-1), NPK content and uptake, and available NPK organic carbon in soil than the other treatments, which were comparable to the N3 (125% RDN + ZnSO4 25 kg ha-1) treatment and the lowest in the control treatment  N1, respectively. Thus, the results suggest that inclusion of inorganic fertilizer along with organic manure (FYM) enhanced the rice yield Therefore, application of conventional puddled transplanted rice (E2, CT-TPR) along with N6 (100% RDF + ZnSO4 25 kg ha-1 + FYM  (5 t ha-1) + PSB (5 kg ha-1)+ Azotobactor 20 kg ha-1 ) found beneficial to increase productivity and soil health of rice crop.

Glutinous Rice

The experiment describes the patterns of plant height, days required for booting, heading and flowering, sterility (%), grain yield, straw yield and harvest index of three glutinous rice (Oryza sativa L.) cultivars namely, Pushbiruine, Kathalibiruine and Pakbiruine grown in the coastal saline soils of South West Bangladesh. The experiment was carried out in a Randomize Complete Block Design (RCBD) during aman season, 2003 at the experimental land of Khulna University, Khulna. The obtained results suggest that Kathalbiruine had better plant growth, considerable booting, heading and flowering periods, higher grain yield and harvest index than Pushbiruine and Pakbiruine. Thus Kathalbiruine may be considered as a potential candidate for cultivation in South-West Coastal Region of Bangladesh.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

Boro Rice

This study was conducted to evaluate the efficacy of different organic manure and inorganic fertilizer on the yield and yield attributes of Boro Rice (Oryza sativa L.). The experiment consisted of 8 treatments, T0: Control, T1: 100% N100P15K45S20 (Recommended dose), T2: 50% NPKS + 5 t cowdung ha-1, T3: 70% NPKS + 3 t cowdung ha-1, T4: 50% NPKS + 4 t poultry manure ha-1, T5: 70% NPKS + 2.4 t poultry manure ha-1, T6: 50% NPKS + 5 t vermicompost ha-1and T7: 70% NPKS + 3 t vermicompost ha-1. At 30, 50, 70, 90 DAT and at harvest stage the tallest plant (24.18, 31.34, 44.67, 67.05 and 89.00 cm) and the greatest number of total tiller per hill (5.43, 11.64, 21.01 and 17.90) at same DAT was recorded from T5 and the lowest was observed from T0 in every aspect. The maximum number of effective tillers per hill (13.52), the longest panicle (24.59 cm), maximum number of total grain per plant (97.45), the highest weight of 1000 seeds (21.80 g), the maximum grain yield (7.30 t ha-1) and straw yield (7.64 t ha-1) was recorded from T5 treatment whereas the lowest number of effective tillers per hill (6.07) , the shortest panicle (16.45 cm) , the minimum total grain per plant (69.13) , the lowest weight of 1000 seeds (16.73 g), the lowest grain yield (2.06 t ha-1) and straw yield (4.63 t ha-1) was observed from T0 treatment. Although the highest biological yield was recorded from T5 treatment but statistically similar result were found from T3, T4 and T7 treatments. The highest harvest index also recorded for T5 treatment. It was obvious that yield of rice can be increased substantially with the judicious application of organic manure with chemical fertilizer.
