Abstract
The production and productivity are directly related with use in unit operation of agricultural production. The variation in yield of crop occurs in India due to wide variation in energy inputs, agro-climatic conditions and resources used. Keeping this in view, a study has been carried out to find the energy scenario of wheat crop and to optimize energy inputs for wheat production in Tarai region of Uttarakhand, India. The scenario shows, energy consumption was highest in tractor farm followed by mixed farm in wheat crop for Tarai region of Uttarakhand. In general, it was observed that fertilizer was the highest energy consuming source for wheat production. Threshing was highest energy consuming operation, which generally ranged from 31 to 36 per cent of total operational energy. The consumption of total energy ranged from 16308 to 20157 MJ-ha-1 for wheat crop in Tarai region. The yield and energy productivity of wheat crop can be improved by using optimum energy resource allocations obtained through optimization by 4150 to 6000 kg-ha-1 and 0.254 to 0.418 MJ-kg-1 respectively. Through use of optimization technique and recommended package of energy inputs the easily achievable yield in case of wheat is 6000 kg-ha-1 in Tarai region of Uttarakhand.
Sažetak
Proizvodnja i produktivnost su direktno povezani sa upotrebom u jediničnim operacijama poljoprivredne proizvodnje. Varijacije u prinosima u Indiji se pojavljuju zbog velikih variranja energetskih inputa, agro-klimatskih uslova i iskorišćenih resursa. Imajući ovo u vidu, izvedeno je istraživanje da bi se našao energetski scenario proizvodnje pšenice i optimizovali energetski inputi u proizvodnju pšenice u regionu Tarai u Uttarakhand, Indija. Scenario pokazuje da je potrošnja energije bila najveća na farmama sa traktorima, a zatim na mešovitim farmama u ovom regionu. Generalno, uočeno je da je đubrivo bilo najveći potrošač energije u ovoj proizvodnji. Vršidba je bila operacija sa najvećom potrošnjom energije, koja je generalno iznosila 31 do 36% od ukupne energije u svim operacijama. Ukupna potrošnja energije u ovom region iznosila je od 16308 do 20157 MJ-ha-1. Prinos i energetska produktivnost pšenice mogu da se unaprede upotrebom energetskih resursa sa optimalnih lokacija, dobijenih optimizacijom za 4150 do 6000 kg-ha-1 i 0.254 do 0.418 MJ-kg-1, redom. Upotrebom tehnike optimizacije i preporučenog paketa energetskih inputa lako je postići prinos pšenice od 6000 kg-ha-1 u Tarai regionu Uttarakhanda.
