摘要：
An energy workout for any crop production suggests managing energy inputs and improving energy productivity in crop production. Based on this theory, energy input and out put in organic and conventional production of guava cv. Allahabad Safeda was worked out. Machinery consumed less energy (577.8 MJ) and chemical fertilizers ranked first (10088 MJ) in energy consumption. Maximum input energy was consumed (13523.41 MJ) in application of recommended doses of chemical fertilizers as compared to (5216.9 MJ) in T3. Output input and energy ratio (9.90) was highest in T3 compared to 3.48 with application of recommended dose of chemical fertilizers. Net return ((sic) 126895/ha) and benefit cost ratio (4.26) was computed maximum in T3 compared to (sic) 47,570 and 2.82 in T4.
