Rice-based cropping systems are the foundation of food security in countries Southeast Asia, but productivity such has declined with deterioration soil quality. These different from other arable because rice is grown under submergence, and this may require a set key attributes for maintenances quality productivity. A minimum dataset was screened assessing soils belonging to three Soil Orders (Inceptisols, Entisols Alfisols) by using statistical mathematical models 27 physical, chemical...
A study on the rice–wheat cropping system was conducted at Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India, to assess effects of long-term manuring and fertilization transformation inorganic phosphorus (P) fraction in soil after 22 years crop cycle. Soil samples were collected Kharif from seven treated plots having different types organic amendments like farm yard manure, paddy straw green with 50% substitution nitrogen levels rice only. The result showed that yield trend maintained...
The experiment was conducted in a 22nd cycle of rice-wheat rotation established the eastern India with randomized block designed various combinations inorganic and organic sources nutrients like farm yard manure (FYM), paddy straw (PS), green rice crop only. Application nitrogen, phosphorus, potassium (NPK) its combination FYM, PS, manuring increased grain yield significantly. Rice declined only control plots (−0.003 t ha−1 year−1), whereas positive trend maintained all treatments. All...
The impacts on yields of cluster bean were assessed for normal (15 July) and late (30 sowing environments foliar spray thiourea (500, 1000 ppm) salicylic acid (50, 100 at 45 60 days after (DAS).Significantly higher yield parameters, yield, economics, protein content nutrient uptake recorded with 500 ppm as compared to all other bio regulator sprays. Similarly, enhanced growth parameters which statistically par those DAS. data show that the application regulators date enhances seed...
Robust data on the spatial distribution of land degradation is important for resource conservation planning.Spatial status India was mapped using multi-temporal Linear Imaging Self Scanning Sensor (LISS-III) acquired from Resourcesat-1/2 during 2005-2006 and 2015-2016 under Natural Resources Census programme Indian Space Research Organisation.Heads-up on-screen visual interpretation multi-season satellite carried out, supported by digital elevation model other historical maps...
Efficient nitrogen (N) management is critical for sustaining high maize yields while minimizing environmental impacts, as conventional practices often lead to N losses, greenhouse gas emissions, and reduced eco-efficiency. To address these challenges, the “Pusa Doctor” app was developed using dark green colour index (DGCI) precision in maize. The further validated experiment conducted with three rates- 0 kg/ha (N PK), 50 75 PK) basal, along two splits of at 35 45 DAS per PK+App PK+App) GS TM...
The present investigation was carried out in coastal Sundarbans of India to study the effects farm yard manure, green leaf and vermicompost on biological attributes soils yield rice–tomato, rice–sunflower, rice–chili cropping system over conventional farmer's practices (control) by a strip-plot technique for two consecutive years. partial substitution inorganic fertilizers through organics significantly increased various systems. use organic materials improved microbial biomass carbon,...
Organics, biological, and inorganic fertilizers play a crucial role for improving crop yield soil properties. Accordingly, we assessed their impact on yield, microbial activities, transformations of carbon (C), nitrogen (N), phosphorus (P), sulfur (S) in soils under 12-year-old intensively cultivated rice (Oriza sativa L.), mustard (Brassica juncea sesame (Sesamum indicum L.) system with sole (NPK); NPK + farmyard manure (NPKF); green (NPKG) (Sesbania sesban bio-fertilizer (NPKGB)...
