Abstract
One of the most challenges in hybrid maize seed was harvesting direct by self-combine cereal harvest. The objectives of the current study were determined and evaluated economical - Technical parameters for picker-husker auto-harvester maize seed. The split plot experimental design based on the randomized complete block design (RCBD) was used to evaluate treatments with three replications. The main plot was seed moisture content at three levels such as 29, 25 and 21 percent. The sub-plot was the harvesting corn of different methods at four levels (A: by picker-husker auto-harvester, B by PTO connected picker, C: by workers and D: direct harvest by cereal combine for harvesting of maize seed production. According to the results, hybrid maize seed harvesting by picker-husker auto-harvester, PTO connected picker and harvesting by hand are most profitable methods, respectively. Result shooed the mean cracking of seed in harvest with picker-husker auto-harvester and PTO connected picker was 7.11 and 7.7%, respectively. The highest mean fracture was found to be 15.66% in conventional combine. So currently harvesting by picker-husker is most economic and profitable harvest method, all of physical and physiological quality characters and storability was significantly higher than conventional method. Economic survey results with budgeting method showed that harvesting corn seed with a new self-propelled at moisture content of 29 percent was the most profitable technique for farmers.
