Abstract

The aim of the study is assessment of the energy requirements and economics was carried out at the during the year of 2017-18 and 2018-19 involving four plant geometries under rainfed and one life saving irrigation were taken up in pigeonpea (medium duration) under semiarid conditions at Warangal, Telangana, India. Results revealed that pigeonpea cultivated in square seeding (180 × 60 cm), the net profit from pigeonpea was `47 × 103 ha-1 under rainfed conditions compared to rainfed cotton, while pigeonpea cultivated under one protective irrigation at bud initiation stage gave `65 × 103 ha-1 more net profit than the irrigated cotton (irrigation at boll development stage). Pigeonpea and cotton systems were subjected to energy use and out put assessment, net return of energy and income.The highest energy use efficiency (2.88) and net energy (15771 MJ ha-1) and energy productivity (0.20 kg MJ-1) while, lowest energy intensiveness (0.32 MJ `-1) and specific energy (5.11 MJ kg-1) were

Keywords

Conclusion

The energy use efficiency, specific energy, energy intensiveness,energy productivity, net energy and of pigeonpea production system were 2.12, 6.93 MJ kg-1, 0.34 MJ `-1, 0.14 kg MJ-1 and 9351 MJ ha-1 under rainfed conditions respectively. The results indicate that pigeonpea production is efficient system in terms of energy consumption. While, 0.79, 14.99 MJ kg-1, 0.47 MJ `-1, 0.07 kg MJ-1 and -3630 MJ ha-1 of energy use efficiency, specific energy, energy intensiveness, energy productivity, net energy for cotton production system under rainfed conditions. Thus, indicating that the pigeonpea production system can replace cotton production system as it is with best fit crop under rainfed conditions producing increased the seed output, net profit, net energy yield, ultimately increased energy use efficiency of inputs.
