Abstract

The objectives of this research is to know the effect of row spacing and defoliation to growth and yield of the sweet corns. This experiment has been done at the farmland of Muhammadiyah University of Malang started from November 2007 until February 2008 at Tegalgondo Village, Karang Ploso Sub District in Malang on + 550 m dpl above sea level, using pH 5-6. The research used Randomized Block Design (RBD) with two factors and three replications. The first factor is row spacing and consist of two levels: 70 x 10 cm (J1) and 70 x 20 cm (J2), and the second factor is defoliation and consist of three levels: without defoliation (D0), Defoliation of 2 leaves (D1), Defoliation of 4 leaves (D2) and defoliation of staminate (D3). The observation was done on 21-51 days after planting at interval of 10 days. The observed parameters comprised of the plant height, width of the leaf, dry weight of the total plants, growth rate, light intensity, and fresh weight of the covered cob, fresh weight of uncovered cob, length of the cob as well as its diameter. The result of the experiment showed no interaction between row spacing and defoliation to variable of the plant height, width of leaf, dry weight of total plants, growth rate, light intensity, fresh weight of the covered cob, and fresh weight of uncovered cob, as well as length of the cob, but they show significant difference. There is an interaction between row spacing and defoliation of staminate at the variable of cob diameter. The highest diameter of the cob from the combination of row spacing 70 x 20 cm and defoliation of the staminate as 14,50 cm.
