Combination urea and compost fertilizer with different defoliation affected corn and peanut production based on integrated farming system

Abstract

This research was aimed to study the effect of combination of compost and urea fertilizer, leaf defoliation intercropping system of corn and peanut crop. This study was conducted for 4 months and designed by Separate Plot Design. Defoliation of leaves under cob is main plot and combination of urea and compost doses is subplot. The treatments are as follows; main plot d0 = Without defoliation (control); d1 = 50% Defoliation; d2 = 100% Defoliation and combination of Urea and Compost doses; Subplot; p0 = 250 kg Urea/ha + 3 tons of compost/ha; p1 = 230 kg Urea/ha + 6 tons of compost/ha p2 = 210 kg Urea/ha + 9 tons of compost/ha; p3 = 190 kg Urea/ha + 12 tons of compost/ha. Each combination is repeated three times so that the total number is 36 plot experiments. Data were analyzed by using variance analysis and analysis of continuation test of least significance different (LSD). The results showed that the combination of fertilization is the same dry shelled corn production and dry peanut. d1 treatment and its interaction could increase dry production of shelled corn and peanut. Intercropping of corn and peanut is feasible to be cultivated in an integrated farming system.
