The net arable land area is declining worldwide rapidly due to soil erosion, drought, loss of organic carbon, and other forms degradation. Intense rainfall, cultivation along steep slopes, unscientific land-use changes, shifting cultivation, acidity, nutrient mining in hills mountains make agriculture unsustainable less profitable. Hills mountain ecosystems the Eastern Himalayan Region (EHR) are further prone impact climate change posing a serious threat agricultural production environment....
Abstract Poor soil properties and low moisture content (SMC) are major limitations for cultivating a second crop after the rainy season rice ( Oryza sativa L.) in uplands of Eastern Himalayas. Information on impact conservation tillage residue management (RM) to alleviate constraints is limited region. Thus, field study was conducted rice–rapeseed Brassica campestris Var. Toria) system under rainfed conditions with two systems (CsT—conservation CT—conventional) five RM practices (100% NPK...
Rhizosphere microbiome significantly influences plant growth and productivity. Legume crops like pea have often been used as a rotation crop along with rice cultivation in long-term conservation agriculture experiments the acidic soils of North-East Region India. It is essential to understand how soil communities shapes its rhizosphere microbiome. also expected that application nutrients tillage practices may lasting effect on communities. In this study, we estimated bacterial by 16S rRNA...
Abiotic stressors such as drought and heat predispose chickpea plants to pathogens of key importance leading significant crop loss under field conditions. In this study, we have investigated the influence high temperature on incidence severity dry root rot disease (caused by Macrophomina phaseolina) in chickpea, extensive on- off-season trials greenhouse We explored association between tolerance resistance two genotypes, ICC 4958 JG 62, with contrasting rot. addition, extensively analyzed...
Maize is a major crop of the Eastern Himalayan Region (EHR) which faces significant environmental challenges including waterlogging (WL) under changing climate. Through microcosm and field experiments, this study aimed to evaluate phenotypic plasticity adaptive mechanisms maize landraces WL conditions at seedling flowering stages. Based on response coefficient tolerance 14 stage were found be tolerant whereas RCM-12-19, RCM-32-19, RCM-16-19, emerged as both At stage, Root Length ratio (RLR)...
Climate change, land degradation, and shrinking resources are major limitations for increasing crop productivity in the East Himalayan Region (EHR). Agroforestry having a plethora of complementarities is preferable land-use option improving agricultural while conserving natural resources. The effects agroforestry systems with Gamhari ( Gmelina arborea ) (GAFS) Alder Alnus nepalensis (AAFS) as tree components, on soil nutrients, physiological characteristics, turmeric Curcuma longa L.),...
Yield potential of maize having distinct genetic diversity in Eastern Himalayan Region (EHR) hill ecologies is often limited by Al toxicity caused due to soil acidity. Stress physiological analysis local check exposed 0 300 μM under sand culture revealed that 150 as critical and 200 tolerable limit. Increase from reduced total chlorophyll, carotenoids 74.8% 44.7% respectively enhanced anthocyanin 35.3% whereas LA, SLW SL have 81.3, 21.3% 47.8% respectively. R/S ratio was 51.0 13.7% higher at...
Introduction Organic farming is a promising solution for mitigating environmental burdens related to input-intensive agricultural practices. The major challenge in organic agriculture the non-availability of large quantities inputs required crop nutrition and sustaining soil health, which can be resolved by efficient recycling available on- off-farm resources integration components as per specific locations. Methods An integrated system (IOFS) model comprising horticultural crops, rainwater...
Abstract Seasonal variations in rainfall patterns, particularly during sowing, early growing season, and flowering, drastically affect rice production northeastern India. However, sensitivity to drought stress is genotype-specific. Since 80% of the land this region used for production, it crucial understand how they have adapted water stress. This study evaluated 112 genotypes grown NE India seed germination percentage seedling development under PEG-mediated Among genotype, Sahbhagi dhan,...
Low productivity and energy use efficiency (EUE) of rice farming are the major concerns for agricultural sustainability in Eastern Himalayan region India. A field experiment on (Oryza sativa L.)-pea (Pisum sativum L) system was conducted three consecutive years during 2012–15 lowland ecosystem to assess direct residual impact tillage residue management (RM) practises sustainability. Significantly higher grain yield achieved under no-till (NT) than minimum (MT) conventional (CT). Among RM...
Rhizoctonia bataticola causes dry root rot (DRR), a devastating disease in chickpea (Cicer arietinum). DRR incidence increases under water deficit stress and high temperature. However, the roles of other edaphic environmental factors remain unclear. Here, we performed an artificial neural network (ANN)-based prediction considering data from previous reports weather factors. ANN-based using backpropagation algorithm showed that combination total rainfall November to January chickpea-growing...
Frost in the uplands of northeast India frequently damages maize, leading to poor yields or even complete crop failure. We studied feasibility using reflectance spectra from a handheld radiometer and camera on board drone at 80 m above assess physiological changes, differential responses nutrient managements (N, P, NPK) also predicted likely losses grain yield caused by one night's frost damage 90-day-old maize Meghalaya, India.

Millets are nutritionally superior and climate-resilient short-duration crops hold a prominent place in cropping sequences around the world. They have immense potential to grow marginal environment due diverse adaptive mechanisms.An experiment was conducted an organic production system North Eastern Himalayan foothills of India for 3 consecutive years by evaluating high-yielding varieties (HYVs) different millets, viz., finger millet, foxtail little barnyard proso browntop along with local...
Abstract The marginal Himalayan ecosystems have great potential for biochar application conserving soil moisture, ameliorating acidity, improving fertility, and thus, contributing to sustainable intensification. Thus, the efficacy of was tested along with nutrient management practices (NMP) on performance maize ( Zea mays L.)‐French bean Phaseolus vulgaris L.) as emerging cropping system in an acid under rainfed hill ecosystem. rainy season grown three levels (0, 2.5, 5 Mg ha −1 , applied...
A field study was conducted to the effect of sulphydryl bio-regulator like thiourea through foliar application on growth, yield and profitability lentil in rice fallows. The experiment laid out randomized block design replicated thrice with thirteen treatments including water spray (control), 2% urea, 500ppm 1000ppm at different stages crop growth. Results revealed that @ pre-flowering pod initiation recorded significantly increased shoot length (34.1cm), total dry matter (19.52 g plant-1),...
