Tractor Drawn Modular Planter for Gram-A Performance Study

Tarun Kumar Maheshwari and Uday Veer Singh

Abstract

The performance of the tractor drawn modular planter was evaluated in laboratory as well as in field conditions. It consists of 7 rows, row to row spacing was kept 20 cm, working efficiency was 65%, draft required was 2000 N, working capacity was 0.47 ha/h, fuel consumption was 3.5 l/h, operating cost was 740 Rs/h and was operated at 4.0 km/h. The field trial was conducted at Etawah college farm in well-prepared field after rice cultivation. The type of soil was loamy, having initial moisture content of 14.7%. The bulk density of experimental plot after seedbed preparation was 1.53 g/cm3. Its field capacity was 0.47 ha/h, while 0.42 ha/h by multi-crop seed cum ferti drill and 0.152 ha/h by broadcasting. The average loss of seed due to abrasion in metering mechanism of modular planter was 0.73%, which is less than 1.63% of multi-crop seed cum ferti-drill. The average plant population was 23.6plants/m2 for modular planter, which were 23.6% higher than plant population by multi-crop seed cum ferti-drill and 37% by broadcasting method. The average yield of the plots shown by modular planter was 28.5 q/ha while the average yield of multi-crop seed cum ferti-drill was 26.5q/ha and the average yield of broadcasting was 21q/ha. The seed required by modular planter was 90 kg/ha and by multi-crop seed cum ferti-drill was 100 kg/ha and by broadcasting was 120 kg/ha. The time requirement by the modular planter is 2.06 h/ha, which is less than 2.7h/ha by multi crop seed cum fert-drill and 4.7 h/ha by the broadcasting. There was 16.54 % labor saving while using modular planter with respect to the broadcasting method and 4.04% labor saving while using multi crop seed cum fert-drill.
