EFFECT OF SPACING AND K20 ON THE GROWTH AND YIELD OF BROCCOLI (Brassica oleracea L. var. italica)

Abstract

The experiment was conducted at Honiculture Farm. Sher-e-Bangia Agricultural University. Dhaka, during October 2007 to February 2008. The experiment was consisted of two factors, viz. three levels of spacing such as 60 ern x 40 em; 60 cm x 50 emand 60 em x 60 em and four levels of K20 such as 0; 60; 90 and 120 kg/ha fertilizer application. Results revealed that different spacing and K20 levels significantly influenced on growth parameters and yield of broccoli. The maximum plant height, number of leaves. primary curd weight, secondary curd weight and yield per plant were recorded from the widest spacing but the highest yield (14.02 t/ha) was recorded from the closest spacing. On the other hand, all the parameters under study showed better performance with the application of 120 kg KzO/ha. The highest yield (14.70 t/ha) was obtained from this treatment. Combined effect of the closest spacing and the highest dose of K,O also gave the highest yield (16.61 t/ha). The results suggested that 60 cm x 40 em spacing akng wilh 120 kg K,O/ha may be used for higher yield of broccoli.
