Title : ENERGY AND ECONOMIC ASSESMENT IN TILLAGE AND SOWING FOR ROTAVATORS, CONVENTIONAL AND NO-TILL WHEAT ESTABLISHMENT
Abstract : Rice-wheat is major crop of IGP covering around 10 Mha areas and contributing about 40% to national food grain production. Rice residue management in combine harvested fields, for wheat sowing, is performed primarily through intensive tillage. This demands more energy input leading to higher production cost and lesser benefit-cost ratio. Indian government is promoting rotavators for speedy seedbed preparation in rice-wheat system. No-till wheat sowing is also quite popular amongst the farmers. This study compares energy input and benefit-cost ratio of six treatments viz. T1 (RM1 x 2 + sowing), T2 (RM2 x 2 + sowing), T3 (RM3 x 2 + sowing), T4 (RM4 x 2 + sowing), T5 (No-till sowing) and T6 (Disc harrow x 6 + Planking x 2 + sowing). Result revealed maximum time and fuel consumed in T6 (10.13 h/ha and 59.85 l/ha) and minimum for treatment T5 (1.39 h/ha and 6.19 l/ha). Energy saving was maximum (89.57%) in no-till wheat sowing (T5) followed by rotavator treatments (47.08-62.65%) compared to treatment T6. The energy productivity was highest (13.06 kg/MJ) for no-till sowing (T5). It ranged from 2.73-4.20 kg/MJ for rotavator treatments (T1-T4) and was minimum (1.59 kg/MJ) for T6. The benefit-cost ratio was found 2.99 for treatment T6 and 6.35% higher for no-till wheat sowing (T5). It ranged from 2.91-3.53 for treatments (T1-T4). Based on the results, T5 was found most energy efficient treatment followed by T3, T4, T2 and T1. Conventional method (T6) was found to be most energy intensive method of wheat establishment.
