PERFORMANCE EVALUATION OF SEED METERING MECHANISMS WITH DIFFERENT SEED DRILLS FOR BENGALGRAM
131 / 189
Abstract
In the present study five types of seed drills were evaluated for Bengalgram crop to assess their performance.
The highest field capacity was found to be 0.47 ha h-1 with field efficiency of 66.75 per cent for Ananta planter among
all treated seed drills. The lowest seed rate obtained in the field was observed as 64.37 kg ha1 for Ananta planter
among all seed drills whereas the highest seed rate was observed as 79.15 kg ha-1 for local seed cum fertilizer drill.
The highest seed yield obtained was found to be 929.60 kg ha-1 for Ananta planter among all seed drills whereas the
lowest seed yield was found to be 783.30 kg ha-1 for TNAU model seed cum fertilizer drill. The cost of cultivation for
Bengal gram crop obtained were that Rs.12,034, Rs.12,331, Rs.12,425, Rs.12,681 and Rs.12,680 per ha for Ananta
planter, Nandyala planter, Gujarat seed cum fertilizer drill, TNAU model seed cum fertilizer drill and Local seed drills
respectively. The highest net profit was found to be Rs.29,798 ha-1 for Ananta planter among all seed drills. The lowest
net profit was found to be Rs. 22,568 ha-1 with TNAU model seed cum fertilizer among all seed drills.The study
conferred that out of five seed drills the Ananta planter has given best performance as compared to others.
