CHEMICAL AND MORPHOLOGICAL PARAMETERS OF SWEET CORNS INFLUENCED BY PRODUCTION METHOD

Abstract

This field experiment was conducted to see the influence of production methods (open field/green house) on some morphological and chemical characteristics of super sweet (SH2) corn hybrid. The study was established at a local farm in Bogojevce (Municipality of Leskovac, South Serbia). The highest values of morphological characteristics (total plant hight and first cob hight) were achived when Sweet Nugget F1 was grown at open field. The production method did not have statistically significant impact on the average velues of the observed morphological parameters. The highest amount of total sugar and invert sugar in maize kernel was achived when grown in open field with the values of 11.04% and 7.24% respectively. When grown under greenhouse conditions, the total sugar amount was 8.04%, whereby the amount of invert sugar was 4.29%. A positive and very strong correlation between total sugars and invert sugars was observed.
