EFFECT OF RESOURCE CONSERVATION MACHINERIES ON TRACTIVE, FUEL AND POWER DELIVERY EFFICIENCIES, UNDER RAINFED CONDITION OF NORTH-GUJARAT REGION FOR GREENGRAM [Vigna radiata L.]
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
Field experiment was conducted to compare tractive, root profile and crop parameters among resource conservation machineries and conventional practice under leveled and unleveled plots for three consecutive years from kharif-2012 to kharif-2014, comprising of two main treatments i.e. No Leveling (L0) and Leveling with laser land leveler(L1) and five sub treatments viz., zero till drill (M1), roto till drill (M2), strip till drill (M3), raise bed planter (M4) and conventional practices (M5). The five sub-treatments i.e., M1, M2, M3, M4 and M5 were performed uniformly under L0 and L1. The experiment was carried out for green gram crop in the research farm of Centre for Watershed Management and Participatory Research and Rural Engineering, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat State. The result revealed that the treatment L1 offered 5.79 per cent higher effective field capacity (EFC), 0.77 per cent more tractive efficiency, 3.40 per cent higher power delivery efficiency, 7.62 per cent less volume of soil disturbance, 6.50 per cent more fuel efficiency, 6.33 per cent less energy and 8.00 per cent reduction in surface soil disruption than the treatment L0. Among resource conservation machineries M1 recorded higher effective field capacity and tractive efficiency of 0.504 ha/hr and 71.87 per cent, which was correspondingly 51.78 and 2.05 per cent more than M5. M2 presented maximum value of power delivery efficiency equivalent to 18.73 per cent, which was 19.59 per cent higher than M5. M1 recorded lowest soil volume disturbance (359.68 m3/hr) among sub-treatments, which was 38.65 per cent lower than M5. Fuel consumption and energy requirement presented by M1 was lowest with corresponding value of 7.60 l/ha and 77.96 kWh/ha, which were 47.94 and 47.76 per cent lesser than M5. The treatments M3 and M2 stood second and third reporting fuel consumption equivalent to 8.51 and 8.91 l/ha, respectively. M1 presented minimum surface soil disruption of 92.05 cm2, which was lower by 50.99 per cent compared to M5
