Influence of urea fertilizer applied with polyacrylate polymer, zeolite and Mimba on growth maize

Abstract

Abstract This research was carried out to study the growth of maize fertilized with a composite of urea with slow release materials (polyacrylate polymer and zeolite) and nitrification inhibitors, Mimba ( Azadirachta indica ). Three times repetitions of Randomized Block design was used in this study. The parameters observed included biomass (g), the weight of cobs (g) and the length of cobs (cm). The weight and the length of corn cobs were measured after harvest. The result of the study shows that the growth of maize applied with urea fertilizer composited with polymeric polyacrylate, zeolite and Mimba was significantly different from the negative control (KH 2 PO 4 /Mono potassium phosphate) fertilizer and appeared to be significantly better than the positive control (Urea and KH 2 PO 4 fertilizers).
