摘要

The effect of organic manure and chemical fertilizers on vegetable crops and soil properties in the radish-stem amaranth-Indian spinach cropping pattern was studied in a homestead area of Gazipur district in Bangladesh. There were eight treatments - poultry manure (PM) 5 t ha -1 (T 1 ), cowdung (CD) 10 t ha -1 (T 2 ), household waste (HW) 10 t ha -1 (T 3 ), PM 2.5 t ha -1 + reduced RDF (recommended dose of fertilizer) (T 4 ), CD 5 t ha -1 + reduced RDF (T 5 ), HW 5 t ha -1 + reduced RDF (T 6 ), 100% RDF (T 7 ) and Control (T 8 ). The 100% RDF treatment (T 7 ) gave the highest radish yield, however identical yield was obtained with T 5 and T 6 treatments. The maximum yield of stem amaranth and Indian spinach was obtained with T 4 and T 6 treatments, respectively. The highest N, P, K and S uptake was found in T 7 for radish, T 4 for stem amaranth and T 6 for Indian spinach. Soil bulk density and organic carbon were improved due to application of organic manure. The highest nutrient availability was recorded with T 4 treatment that was followed by T 6 . Among the treatments, the poultry manure 2.5 t ha -1 + reduced dose of recommended fertilizer and house hold waste 5 t ha -1 + reduced dose of recommended fertilizer were found suitable for achieving sustainable vegetable crop yield as well as for susteanace of soil health at homestead area.
