Response of some quantity yield traits of sweet corn (Zea mays L .var saccharata) for planting dates and spraying with biostemulators.
Abstract
the experiment Carried out in the vegetable fields of the Department of Horticulture and landscaping - Faculty of Agriculture - University of Baghdad, for the autumn season 2012 and the spring season 2013 in order to study response of some quantity yield traits of sweet corn (Zea mays L .var saccharata) for planting dates and spraying with biostemulators. Experience autumn season included two dates August 1 and August 15 and the spring season on four dates 15 February, 1March, 15March, 1April , All included on the transaction date three types of biostemulators Disper Root, Disper Chlorophyll and Disper Vital concentration of 1 g. L-1, can be summarized results of the experiment as follows: Affected planting dates morally in most traits for sweet corn yield, in the autumn season of cultivated plants investigated the date August 15 for the highest number of grains per cob. Fresh Ear yield . Biostimulators treatments rise to significant differences in the characteristics of sweet corn plant yield, as characterized by the treatment of Biostimulators Root 2 + Chloro in the spring and autumn seasons best rates, cob length 21.06 و 19.24 cm , row per cob 18.71 و 17.77 , grain per cob 544.0 و 462.4 , and Fresh Ear yield 16.93 و 12.48 kgm. h-1. And achieved Interference between planting dates and Biostimulators significant effect in some of the yield traits to sweet corn, and for two seasons, respectively
