Application of chicken manure on lowland cabbage (Brassica oleracea var. Capitata) grown on peat soil under rainshelter

M.K. Illias and P. Vimala

Abstract

A study was conducted to determine the effects of chicken manure on lowland cabbage grown on peat soil under rainshelter. Chicken manure at 20, 30 and 40 t/ha were applied all as basal or split into two equal applications as basal and at 4 weeks after transplanting. The plant canopy, fresh weight of outer leaves and yield of plants treated with chicken manure at 20–40 t/ha were similar to those from plants treated with inorganic fertilizer. Soil and leaf nutrient analyses also indicated that chicken manure as the sole source of nutrients could improve soil fertility and provide enough nutrients for good growth and yield. Crops fertilized with chicken manure alone gave yields between 20.77–24.67 t/ha, similar to the inorganic fertilizer. For cabbage grown on peat under the rainshelter, chicken manure at 20 t/ha applied all as basal is recommended.
