چکیده
There is an urgent need for identification of eco-friendly and cleaner production systems that are more productive, profitable, efficiently use energy/water/carbon input environmentally safer. Under context, a long-term experiment was conducted during 2019–21 at the farmers’ fields Krishi Vigyan Kendra (KVK), Gaya, Bihar. The main objective study to evaluate productivity diverse cropping irrigated rainfed conditions. Nine system, viz. transplanted puddled rice (TPR)–wheat (conventional-till)-fallow (farmers practices) [CS1],TPR-wheat(zero-till)-mung (ZT) [CS2], Conventional-till direct seeded (CTDSR)-mustard (ZT)-mung [CS3], ZTDSR-lentil (ZT)-fallow [CS4], Maize (CT)-lentil [CS5], Bajra (CT)- lentil [CS6], (CT)-wheat [CS7], TPR-chickpea [CS8] TPR-maize (CT)-fallow [CS9] were used present study. Maximum system recorded with maize (13.2 t/ha), which 46, 3.9, 13.8, 94.7, 22.2, 15.8, 39.5, 11.9% higher compared CS1, CS2, CS3, CS4, CS6, CS7, CS8 CS9, respectively. Net returns (`211677/ha) Benefit cost (B:C) ratio (3.59) maximum (ZT). Land efficiency TPR-wheat (92.6%). Carbohydrate equivalent yield also Diversification rice-wheat millets i.e. (ZT)/Bajra (ZT)- mung improves by 19.5–26.1% (CT)-fallow. Thus, could be important identify alternate enhancing overall profitability sustainably through adoption environment-friendly technologies.

Crop growth simulation models provide a means to quantify the effects of climate, soil, and management on crop growth and biogeochemical processes in soil. The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate N dynamics and balance in the rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping systems in the Indo-Gangetic Plains with various N and wa...

The history of the Indo-Gangetic river systems from the late nineteenth to the early twentieth centuries can be reconstructed from the meticulous official records of the survey, meteorological and medical departments of the British Government of India. In contrast with the grand sweep of the geological evidence, these records indicate a complex narrative of floods, droughts and channel shifts. ...
