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).
