Abstract:

Cabbage (Brassica oleracea L.) is a member of the cole crops, and it is an important fresh and processing vegetable crop in most of the countries of the world. However, yield of the crop is often constrained by low and imbalanced nutrient supply in the country at large and in Gudji Zone in particular. Therefore, this study was conducted at the Bore Agricultural Research Center (BoARC) during the period from July 1, 2014 to December 2, 2014 main cropping season to assess the effects of different rates of Nitrogen (N) and farmyard manure (FYM) on growth and yield of cabbage. The treatments consisted of five levels of N (0, 59,119, 235 and 294 kg N ha-1) and four levels of FYM (0, 3, 6 and 10 t ha-1) in factorial combinations and were laid out in randomized complete block design (RCBD) with three replications. The results showed that interaction effects of N and FYM highly significantly (P
