Influence of Row Direction and Spacing on Growth, Yield and Oil Content of Toria (Brassica compestris)

Abstract

A Field experiment was conducted to study the effect of row direction and row spacing on growth, yield and oil content of toria. The treatments consisted of two row directions (North- South and East-West) and four row spacings (25, 30, 35 and 40 cm). Among the row directions, maximum plant height (108.57 cm), number of primary branches/plant (6.63), number of secondary branches/plant (11.44) and plant dry weight (33.82 g) were recorded under North- South direction, whereas, among the row spacing, maximum plant height (113.94 cm), number of primary branches/plant (8.33), number of secondary branches/plant (14.91) and plant dry weight (34.92 g) were recorded with wider (40 cm) row spacing. The results indicated that maximum number of siliqua per plant (295.08), number of seeds per siliqua (15.85), test weight (3.51 g), seed yield (11.63 q ha -1 ), harvest index (26.94 %) and oil content (38.41 %) were obtained under north-south row direction, whereas, amongst the row spacings the highest number of siliqua per plant (353.83), number of seeds per siliqua (16.77), test weight (3.81 g), seed yield (14.75 q ha -1 ), harvest index (29.56 %) and oil content (41.33 %) were recorded under 40 cm row spacing.
