Energetics and Economics of Rabi Maize as Influenced by Smart Nutrient Management Under South Odisha Conditions
Journal Title: International Journal of Experimental Research and Review - Year 2024, Vol 44, Issue 8
Abstract
Cereal crop cultivation is one of the essential agricultural practices adopted worldwide to feed human beings, providing dietary energy and food security. Maize is important in different cereal crops' areas, production, and productivity. In high-input-demanding crops like maize, it is mandatory to evaluate the energy input and output along with the economics of the study for better optimization of resources and efficient management of inputs in maize cultivation. The present study was conducted at the Postgraduate Research Farm of Centurion University of Technology and Management, Odisha, India, for two consecutive years during the Rabi season (November-March) of 2021-22 and 2022-23. The experiment was carried out in brown forest soil, sandy loam in texture and a Randomized Complete Block Design with 13 treatments, and each treatment was replicated thrice. The treatments comprise various graded fertilizer levels, precision nitrogen management treatments, decision support systems-based nutrient management and nano nitrogen treatment. The results revealed that among the nutrient management treatments, the highest input energy (21546.8 MJ ha-1) was recorded in the treatment T4: 150% RDF. In terms of output energy and net energy, the highest values were recorded in the treatments T10: CCM-based sufficiency index at 90%-95% and T4: 150% RDF. The energy use efficiency and energy productivity were recorded as the highest values in the treatments T9: CCM-based sufficiency index at 85%-90%. Further, among the nutrient management treatments, the maximum cost of cultivation was incurred in the treatment T4: 150% RDF and it was closely followed by T9: CCM-based sufficiency index at 85%-90% and T10: CCM-based sufficiency index at 90%-95%. The highest gross and net returns were recorded in the treatment T10: CCM-based SI at 90%-95%. In the case of the benefit-cost ratio, the highest value (1.29 and 1.24 for two consecutive years of the study, respectively) was recorded in the treatment T10: CCM-based sufficiency index at 90%-95%. The findings of this study demonstrate the potential of precision nutrient management through the CCM Sufficiency index in Rabi maize cultivation under South Odisha for more sustainability and productivity with the highest profitability.
