摘要
Different kind of organic manure, farmyard manure （FM）, chicken manure （CM） and blood meal （BM）, was tested during three successive seasons in order to reveal the effects of the applications on the macro nutrient contents of soil under cabbage （Brassica oleracea L.） growth. 17 organic manures and ! control, collectively 18 treatments, were used in a randomized block design with four replications under the open field conditions. As a result, total nitrogen （N）, phosphorus （P）, magnesium （Mg） and potassium （K） contents were influenced by the treatments to a different extent, while calcium （Ca） contents were less influenced. Evaluating the seasonal mean, P and K contents rose significantly from autumn 1 to autumn 2 season, but the increase in total N, Ca and Mg contents were found to be statistically insignificant. Consequently, 10.0 ton ha-1 FM ＋ 1.2 ton hal CM and 1.7 ton ha-1 CM ＋ 7.5 ton ha^-1 FM treatments gave the better results than the others. FM and CM treatments gave the better results than the BM treatment and we concluded that the BM should be used in small quantities in mixtures.
