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...
South Asian countries will have to double their food production by 2050 while using resources more efficiently and minimizing environmental problems. Transformative management approaches technology solutions be required in the major grain-producing areas that provide basis for future nutrition security. This study was conducted four locations representing systems of densely populated regions Asia. Novel production-scale research platforms were established assess optimize three futuristic...
A pearl millet inbred germplasm association panel (PMiGAP) comprising 250 lines, representative of cultivated from Africa and Asia, elite improved open-pollinated cultivars, hybrid parental inbreds mapping population parents, was recently established. This study presents the first report genetic diversity in PMiGAP its exploitation for drought tolerance traits. For structure analysis, genotyped with 37 SSR CISP markers representing all seven linkage groups. it phenotyped yield components...
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...
Abstract Major nutrient management systems for rice-wheat cropping were compared their potential to credit organic carbon (C) the soil, its fractionation into active (very labile, VLc; Lc) and passive (less LLc; non-labile, NLc) pools, crop yield responses. A ten-year long experiment was used study effects of: (i) no inputs (Control, O), (ii) 100% inorganic fertilizers (F) reduced (55%) supplemented with biomass incorporation from (iii) opportunity legume ( Vigna radiata ) (LE), (iv) green...
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...
Rice is a staple food crop in Asia and plays crucial role the economy of this region. However, production rice its cultivating areas are under constant threat soil salinity. A major QTL, Saltol, responsible for salinity tolerance at seedling stage has been mapped on chromosome 1 using Pokkali/IR29 Recombinant Inbred Lines (RIL) population. The present study was aimed to incorporate Saltol Quantitative Trait Loci (QTL) two high yielding mega varieties i.e. Pusa44 Sarjoo52 through Marker...
In the present study, a total of 53 promising salt-tolerant genotypes were tested across 18 salt-affected diverse locations for three years. An attempt was made to identify ideal test and mega-environments using GGE biplot analysis. The CSSRI sodic environment most discriminating location in individual years as well over could be used screen out unstable salt-sensitive genotypes. Genotypes CSR36, CSR-2K-219, CSR-2K-262 found Overall, CSR-2K-262, CSR-2K-242 superior stable among all with...
