A field experiment was conducted at the Agricultural College, Bapatla, AP, India during kharif and rabi seasons from 2019 to 2021 using different establishment and nutrient treatments. The objectives of this study were to evaluate the energetics between the treatments in the rice–green gram. The results indicated that the input and output energy were the highest in the conventio­nal and the lowest in the minimum tillage. Highest total energy productivity and energy use efficiency were recorded with the reduced tillage. In case of nutrient management, the highest input, output energy and energy productivity and energy use efficiency were recorded with inorganic fertilizer + cured poultry manure treatments. It can be concluded that the reduced tillage with the application of inorganic fertilizer + cured poultry manure is the best in the constraints-prone coastal zone with limited irrigation facilities due to low require­ment of non-rene­wable energy

Abstract


A field experiment was conducted at the Agricultural College, Bapatla, AP, India during kharif and rabi seasons from 2019 to 2021 using different establishment and nutrient treatments. The objectives of this study were to evaluate the energetics between the treatments in the rice–green gram. The results indicated that the input and output energy were the highest in the conventio­nal and the lowest in the minimum tillage. Highest total energy productivity and energy use efficiency were recorded with the reduced tillage. In case of nutrient management, the highest input, output energy and energy productivity and energy use efficiency were recorded with inorganic fertilizer + cured poultry manure treatments. It can be concluded that the reduced tillage with the application of inorganic fertilizer + cured poultry manure is the best in the constraints-prone coastal zone with limited irrigation facilities due to low require­ment of non-rene­wable energy
