Response of N and P on growth and yield of sprouting broccoli (Brassica oleracea var. italica)

The field experiments were conducted at Vegetable Research Farm, Dr Y.S. Parmar University of Horticulture and Forestry, Nauni, Solani, during 1995–96 and 1996–97 to find out the response of spouting broccoli ‘Green Head’ to different levels of N (30, 60, 90 and 120 kg N/ha) and P (30, 60 and 90 kg P₂O₅/ha). It was noticed that when N and P were applied alone, maximum values with respect to plant height, plant frame, head size, head yield/plant and per hectare were obtained at 120 kg N and 60 kg P₂O₅/ha, respectively. However, when N was applied in combination with P, maximum head yield/plant as well as per hectare were obtained at a treatment combination of 90 kg N and 60 kg P₂O₅/ha, resulting in a maximum cost: benefit ratio of 1: 2.35.
