EFFECT OF RATES OF ORGANIC FERTILISER ON GROWTH, YIELD AND NUTRIENT CONTENT OF CABBAGE (BRASSICA OLERACEA VAR. CAPITATA) GROWN UNDER SHELTER

This study investigated the effects of various rates of an organic fertiliser (processed poultry manure) on the growth, yield and nutrient content of cabbage grown under shelter on a clay soil, in the lowlands. Treatments consisted of varying rates (0, 15, 30, 45 and 60 t/ha) of processed poultry manure (PPM). The control treatment was an inorganic fertiliser (N:P 2 O 5 :K 2 O: MgO = 12:12:17:2)
