Performance evaluation of hand operated dibbler and for multi seeds

Abstract

A hand operated dibbler was evaluated for its performance without changing the metering mechanism. The performance under study in laboratory tests and field tests were examined. The results revealed that the seed rate required for dibbler was observed to be 73.6 kg ha-1and 46.4 kg ha-1 for groundnut and maize crops (spacing of 2.5 cm×2.5 cm). The missing rate was found to be 6% and 4% for groundnut and maize respectively. An effective field capacity of the dibbler was found to be 0.00646 and 0.00682 ha.h-1 for groundnut and maize crops. The field efficiency was found to be 87.88% and 85.05% with theoretical field capacity for groundnut and maize crops respectively. The average number of seeds per hill for groundnut and maize found to be 1.07 and 1.16 respectively. The number of hills per hour was 953 and 967 for groundnut and maize respectively.
