Article Synopsis
  • The study aimed to assess the impact of different intercropping row ratios and fertilizer levels, along with the use of stress-mitigating chemicals, on nutrient content, land productivity, and economic viability in cowpea and baby corn systems.
  • Conducted at Agriculture University, the experiment involved various combinations of intercropping techniques and fertility levels, revealing that a cowpea + baby corn 2:1 ratio provided advantages in land-equivalent ratio and monetary benefits, despite higher nutrient uptake in sole crops.
  • Results indicated that higher fertility levels (150% of recommended doses) improved overall productivity and nutrient balances, while the use of CaCl 0.5% as a stress mitigation chemical significantly enhanced nitrogen and phosphorus content in the crops

The Multidrug and toxic compound extrusion (MATE) and aluminium activated malate transporter (ALMT) gene families are involved in response to aluminium (Al) stress. In this study, we identified 48 MATE and 14 ALMT gene families in Vigna radiata genome and classified into 5 (MATE) and 3 (ALMT) clades by phylogenetic analysis. All the VrMATE and VrALMT genes were distributed across mungbean chromosomes.

Stability of soil organic carbon (SOC) is pre-requisite for stabilization of C leading to long-term C sequestration. However, development of a comprehensive metric of SOC stability is a major challenge. The objectives for the study were to develop novel SOC stability indices by encompassing physical, chemical, and biochemical SOC stability parameters and identifying the most important indicators from a Mollisol, an Inceptisol, a Vertisol, and an Alfisol under long-term manuring and fertilization.

Over the past century, the average surface temperature and recurrent heatwaves have been steadily rising, especially during the summer season, which is affecting the yield potential of most food crops. Hence, diversification in cropping systems with suitable fertilizer management is an urgent need to ensure high yield potential during the summer season. Since intercropping has emerged as an important strategy to increase food production, the present study comprises five intercropping systems in the main plot (sole cowpea, sole baby corn, cowpea + baby corn in 2:1, 3:1, and 4:1 row ratio), three levels of fertilizer viz.

Article Synopsis
  • - The study investigates how two lentil cultivars, PDL-1 (tolerant) and L-4076 (sensitive), respond to alkaline soil conditions, finding that PDL-1 shows better growth and less salt injury.
  • - Key findings reveal that PDL-1 has a higher accumulation of potassium, better mitotic index, and enhanced levels of antioxidants and osmolytes, contributing to its alkalinity tolerance.
  • - The research identifies significant genes linked to abscisic acid signaling and secondary metabolite synthesis in PDL-1, suggesting these pathways are crucial for improving lentil crop resilience against alkalinity stress in breeding programs.

Legumes are a better source of proteins and are richer in diverse micronutrients over the nutritional profile of widely consumed cereals. However, when exposed to a diverse range of abiotic stresses, their overall productivity and quality are hugely impacted. Our limited understanding of genetic determinants and novel variants associated with the abiotic stress response in food legume crops restricts its amelioration.

In this study, 285 lentil genotypes were phenotyped under hydroponic and alkaline field conditions. Significant genotypic variation for alkalinity stress was observed among the six Lens species screened hydroponically and in the field having pH up to 9.1.
