Soil quality degradation associated with resources scarcity is the major concern for sustainability of conventional rice-wheat system in South Asia. Replacement management practices conservation agriculture (CA) required to improve soil quality. A field experiment was conducted assess effect CA on physical (bulk density, penetration resistance, infiltration) and chemical (N, P, K, S, micronutrients) properties after 4 years North-West India. There were four scenarios (Sc) namely cropping...
In the most productive area of Indo-Gangetic Plains in Northwest India where high yields rice and wheat are commonplace, a medium-term cropping system trial was conducted Haryana State. The goal study to identify integrated management options for further improving productivity profitability while rationalizing resource use reducing environmental externalities (i.e., "sustainable intensification", SI) by drawing on principles diversification, precision management, conservation agriculture....
Intensive tillage based management practices are threatening soil quality and systems sustainability in the rice-wheat belt of Northwest India. Furthermore, it is accentuated with puddling soil, which disrupts aggregates. Conservation agriculture (CA) involving zero tillage, crop residue suitable rotation can serve as better alternative to conventional for maintaining quality. Soil organic carbon an important determinant quality, playing critical role food production, mitigation adaptation...
Long-term changes in average temperatures, precipitation, and climate variability threaten agricultural production, food security, the livelihoods of farming communities globally. Whilst adaptation to change is necessary ensure security protect poor farmers, mitigation greenhouse gas (GHG) emissions can lessen extent future needs for adaptation. Many practices potentially mitigate GHG without compromising production. India third largest emitter world where agriculture responsible 18% total...
Reduction of excess nutrient application and balanced fertilizer use are the key mitigation options in agriculture. We evaluated Nutrient Expert (NE) tool-based site-specific management (SSNM) rice wheat crops by establishing 1594 side-by-side comparison trials with farmers' fertilization practices (FFP) across Indo-Gangetic Plains (IGP) India. found that NE-based can lower global warming potential (GWP) about 2.5% rice, between 12 20% over FFP. More than 80% participating farmers increased...
To contain the COVID-19 pandemic, India imposed a national lockdown at end of March 2020, decision that resulted in massive reverse migration as many workers across economic sectors returned to their home regions. Migrants provide foundations agricultural workforce 'breadbasket' states Punjab and Haryana Northwest India.There are mounting concerns near potentially longer-term reductions labor availability may jeopardize production consequently food security. The timing rice transplanting...
In agriculture production system, soil enzymes are important indicators of quality. Measurements quality parameter changes essential for assessing the impact and crop management practices. Keeping this in view, an experiment was conducted to evaluate enzyme activities namely dehydrogenase (DHA), β-glucosidase, acid alkaline phosphatase (AcP & AlP), fluorescein diacetate hydrolases (FDH), cellulase, urease aryl sulphatase rhizosphere bulk after 8 years different regimes. Soil organic carbon...
Abstract A study was conducted to design productive, profitable, irrigation water¸ nitrogen and energy use efficient intensive cereal systems (rice-wheat; RW maize-wheat; MW) in North-West India. Bundling of conservation agriculture (CA) with sub-surface drip termed as CA + were compared alone conventional tillage based flood irrigated rotation (farmer’s practice; ScI). In contrast till which consumed 1889 mm ha −1 water (2-yr mean), system saved 58.4 95.5% MW rotations, respectively....
Climate smart agriculture (CSA) practices are emerging as sustainable alternative to conventional rice-wheat system pull up natural resources degradation across south Asia. After five years of continuous CSA based experiment, a two study was conducted evaluate changes in microbial biomasses (microbial biomass carbon and nitrogen), enzyme activities (alkaline phosphatase, dehydrogenase
