Integrated farming systems enhance productivity, sustainability, and resilience under climatic variability in rainfed agroecosystems of the Shivalik foothills, Northwestern India

Balwinder Singh Dhillon, M. J. Singh, K. A. Gopinath, Anil Khokhar et autres

Introduction Smallholder farming systems in rainfed and partially irrigated regions are highly exposed to short-term climatic variability, resulting in yield instability, income uncertainty, and livelihood risk. Integrated farming systems incorporating climate-resilient practices are increasingly promoted to enhance system-level performance and buffer climatic …

Trade-offs and synergies of integrated nitrogen–sulfur management for sustainable Indian mustard: yield, profitability, and soil resilience under semi-arid conditions

Sandeep Kumar, Sanjay Singh Rathore, Kapila Shekhawat, Vinod Kumar Sharma et autres

Sulfur (S) is becoming increasingly widespread in Indian agricultural soils because of intensive cropping, declining organic matter, reduced atmospheric deposition and leaching losses, thereby limiting oilseed productivity and soil health. Although micronized sulfur fertilizers offer improved nutrient synchronization, information on their optimum …

Broad Bed + Mulch and Foliar Nutrition of KNO 3 Alleviate Intra‐Seasonal Moisture Stress in Rainfed Maize ( Zea mays L)

Venugopalan Visha Kumari, N. Jyothi Lakshmi, Savitha Santosh, Priya P. Gaurav et autres

ABSTRACT Rainfed maize production is highly vulnerable to intra‐seasonal dry spells and moisture stress, which adversely affect physiological functions, microbial activity and yield. Conventional flat bed planting often intensifies stress impacts. However, improved land configurations, such as broad bed with mulch, combined …
