Yield of Chinese cabbage (Brassica pekinensis) as Affected by Different Rates and Time of Application of Organic Fertilizer

Abstract

The study was conducted to determine the effects of the different rates and time of application of organic fertilizer on the yield of Chinese cabbage; its effect on some soil properties; interaction effect; and on the return on cash expenses (ROCE). The crop was grown in an open field. Pest control was minimal and no commercial or home-made pest control product was used. The different rates of organic fertilizer had no significant effects on marketable yield but application of 10 t/ha enhanced the head weight of Chinese cabbage. Application of 10 t/ha and 15 t/ha of organic fertilizer improved the soil pH, available P and exchangeable K content of the soil. Application of organic fertilizer before transplanting, 15 DAT and 30 DAT decreased the soil bulk density and increased the soil organic matter. Soils supplied with 15 t/ha of organic fertilizer and applied before transplanting, 10 DAT and 30 DAT increased the soil pH, soil OM and available P in the soil but lowered the soil Db. Application of 5 t/ha had the highest return on cash expenses (ROCE).
