A Research on to Effective on Yield and Earliness of Different Sowing Times and Growing Techniques in Sweet Corn (Zea mays saccarata Sturts) in Kahramanmaraş Conditions

Abstract

In order to investigate the effect of different sowing times and growing techniques. On yield and earliness of two sweet corn varieties, this study, was done in Kahramanmaraş conditions in 1997 – 1998 growing years. Kahramanmaraş research station conditions. Field trials arranged in split – split plot design with there replications, varieties sowing times and growing techniques were used an as main, sub and sub – sub plots, respectively. In this study, Merit and Jubilee varieties used as sweet corn varieties. According to result obtained from the experiment interm of starch ration, number of grain per ear and number of plant per unit Merit variety was found to be superior but interm of days two maturity ear lenght Jubilee was superior. It was determined that earliness sweet corn growing was possible by using covered growing techniques on that covered growing techniques possitively influenced the all characteristic studied starch ratio and ear lenght. Effect of sowing times on days the maturity wasn’t significant. If the temperature is low plant adapted itself till the temperature research optimum. But days the maturity increased vice verse decreased. The optimum sowing times for the Kahramanmaraş conditions was 30 March.
