Field experiments were conducted during Kharif-2017 and 2018 at ICAR-Krishi Vigyan Kendra (KVK), Mangaluru of coastal Karnataka to study the effect of integration of organic and inorganic sources of nitrogen on the yield of midland rice. The results indicated that the integration of organic and inorganic sources of nitrogen significantly influenced the growth and yield attributes of rice. The highest grain yield (5434 and 5372 kg ha-1) and straw yield (6817 and 6927 kg ha-1) were recorded in the treatment comprising VC substituted with 50 percent recommended dose of nitrogen which was on par with PM substituted at 50 percent in both the years. A similar trend was also noticed in both the years for the growth and yield parameters where the highest plant height (94.93 and 96.30 cm) highest productive tillers (16.85 and 18.12) and longer panicle length (17.54 and 18.65 cm) was recorded in the treatment where 50 percent nitrogen was substituted by vermicompost compared to control. The remaining treatments of organic substitution ratios with urea also had a beneficial effect on yield and yield parameters of rice compared to control.

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.

Nitrogen Rates

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to examine the effect of number of seedlings hill‑1 and rate and time of nitrogen application on the yield of late transplant Aman rice (cv. BR23). The experiment comprised three levels of number of seedlings hill-1 viz. 2, 4, and 6, three nitrogen rates viz. 0, 60 and 120 kg N ha-1 and three levels of time of nitrogen application viz. nitrogen application in two equal splits at 15 DAT and early tillering stage (ET); nitrogen application in three equal splits at 15 DAT, ET and panicle initiation (PI) stage; nitrogen application in four equal splits at 15 DAT, ET, PI and flowering (F) stages. The experiment was laid out in a randomized complete block design with three replications. Number of effective tillers hill‑1, grain yield and straw yield were the highest when 6 seedlings were transplanted hill‑1 while all yield contributing characters, grain and straw yields were the highest at 120 kg N ha-1. In case of interaction, the highest grain yield was recorded in combination of 6 seedlings hill-1 × 120 kg N ha-1 and 120 kg N ha-1 × three times of nitrogen applications (15 DAT + ET + PI). The highest number of effective tillers hill-1 and grain yield were recorded in 6 seedlings hill-1 × 120 kg N ha-1 × three times N application (15 DAT + ET + PI) and thus this practice appears as the promising one for late transplant Aman rice ( cv. BR23) cultivation.Int J Appl Sci Biotechnol, Vol 3(4): 692-698

Rice was grown in an open-field Gangetic soil condition with arsenic amended irrigation water in experimental plot at Institute of Environmental Science of Rajshahi University to see the effect of arsenic (As) on growth and yield of rice (Oryza sativa L.). A popular aman rice variety named BR-11 was cultivated with arsenic amended irrigation water (0 mg, 0.1 mg, 0.5 mg, 1.0 mg, 2.0 mg and 4.0 mg/L As containing water) in a green house made of transparent poly-ethylene paper. Sodium arsenate (Na2HAsO4) was added to irrigation water for arsenic source. The tillers number, panicle length and grain yield of BR-11 rice were found to decrease significantly (p?0.05) with increase of arsenic (As) concentration in irrigation water. The highest values of plant height and straw yield was observed in 0.5 mgL-1 treatment, whereas highest tillers number, panicles number, panicle length and grain yield were found in control treatment. The lowest values of these parameters were observed in the treatment of 4.0 mgL-1 As containing irrigation water.

A field experiment was conducted during November 2009-April 2010 in Bangladesh Rice Research Institute, Bangladesh to examine the response of two rice (Oryza sativa L.) varieties (BRRIdhan28 and BRRI dhan29) to six N rates of nitrogen fertilizer viz. 0, 50, 100, 150, 200 and 250 kg ha-1. The experiment was conducted in a RCB design with three replications. Grain yields of both BRRI dhan28 and BRRI dhan29 increased significantly in a quadratic fashion with N rates. The highest grain yields were obtained from 150 kg N ha-1 in both the varieties. More than 1 t ha-1 yield was obtained in BRRI dhan29 (6.34 t ha-1) at the same rate of N indicated BRRI dhan29 as a nitrogen efficient variety. However, the predicted economic optimum doses of N appeared to be 156 and 158 kg ha-1 for BRRI dhan28 and BRRI dhan29, respectively. The grain yield was mainly influenced by the number of panicles per hill, which was found to increase with the increase of N rates in both the varieties. The Agriculturists 2016; 14(2) 48-60

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.
