Energy budgeting of colocasia-based cropping systems in the Indian sub-Himalayas

Productivity, Profitability, and Energy Consumption of Potato-Based Intercropping Systems

“…Higher values could be due to better, and efficient, utilization of growth resources resulting from temporal and spatial complementarity (Singh and Ahlawat, 2011). Higher LER in potato+spinach was likely due to trapping of available solar energy that was less for monocropped potato; however, in A c c e p t e d M a n u s c r i p t 8 intercropped potato, assimilation area was increased which resulted into higher solar energy use efficiency (Tuti et al, 2012). In both intercropping systems, potato had negative aggressivity values; radish and spinach had positive values indicating potato was dominated by both intercrops due to intercrop tall stature, higher leaf area, and resource use (Choudhary and Kumar, 2013).…”

“…Energy values of each cropping system were determined based on energy inputs and energy production for individual crops in the system according to Tuti et al (2012) and Choudhary and Kumar (2013). Energy equivalents for all inputs were summed to estimate total energy input ( Table 2).…”

Effects of Resource Conservation Practices on Productivity, Profitability and Energy Budgeting in Maize–Wheat Cropping System of Indian Sub-Himalayas

“…Yield of different crops can be increased up to 30 % by using an optimal level of energy input [5]. When vegetation strips integrate with reduced tillage, nutrient management (bio-resources like FYM, vermi-compost and poultry manure) and weed management, it can lead to a sustainable production system in Indian sub-Himalayas where *82 % of the population lives in rural areas and is chiefly dependent upon crop farming [5]. Minimum tillage is recommended for soils of the Indian Himalayan region due to reduced cost of cultivation, more retention of soil water and physical protection of soil organic carbon (SOC) in the aggregates [6].…”

“…Yield and economical parameters increase linearly as the level of fertility increases, while the reverse trend is observed with energy use efficiency, energy production and energy intensiveness. Yield of different crops can be increased up to 30 % by using an optimal level of energy input [5]. When vegetation strips integrate with reduced tillage, nutrient management (bio-resources like FYM, vermi-compost and poultry manure) and weed management, it can lead to a sustainable production system in Indian sub-Himalayas where *82 % of the population lives in rural areas and is chiefly dependent upon crop farming [5].…”

Energy Budgeting and Sensitivity Analysis of Rice (Oryza sativa) – Wheat (Triticum aestivum) Cropping System in Indogangentic Plains of India

“…The net output energy of a cropping system can be assessed for planning of sustainable cropping systems. Unlike soil fertility, crop yield is inversely related to energy use efficiency, energy productivity, and energy intensiveness (Tuti et al, 2012). Large scale implementation of low input agricultural practices and timely problem solving in the farm will contribute to overcome the energy crisis and which will be a considerable input in ensuring the national food security.…”
