Study the effect of organic and inorganic source on nutrient and their combined effect on growth and yield of broccoli cv. Princess (F1-Hybrid)

Abstract

A field experiment was conducted during winters 2014-15 to study the effect of inorganic and organic fertilizers on growth and yield of broccoli cv. Princess (F1-Hybrid). The maximum curd compactness was noted in the treatment combinations of T2, T6, T10, and T14. The treatment combinations T4 (150:80:60kg/ha + Poultry manure 5t/ha) (M4xF2) were observed significantly maximum curd length (18.36cm), curd diameter (18.59cm), but these are non-significant gross plant weight (1262.00g), marketable curd weight (793.60g), net curd weight (578.00 g), curd yield per plot (18.32kg) and curd yield per hectare (308.06q/ha). The plant height 19.03, 35.10 and 45.89 cm were recorded significantly increased in the treatment F2 (150:80:60kg/ha) at 30, 45 and 60 DAT respectively. The 8.06, 13.94 and 16.43 cm leaves per plant were noted in the treatment F2 (150:80:60kg/ha) at 30, 45 and 60 DAT respectively. The maximum leaf length (40.83 cm), leaf width (16.80 cm), stalk length (23.39 cm) and stalk diameter (41.20 cm) were exhibited in the treatment F2 (150:80:60kg/ha) at 30, 45 and 60 DAT respectively. Amongst the different treatments of inorganic curd, F2 (150:80:60kg/ha) were found significantly maximum curd length (17.83 cm), curd diameter (18.00 cm), gross plant weight (1116.86 g), marketable curd weight (799.33g), net curd weight (634.33 g), curd yield per plot (18.93g) and curd yield per hectare (308.06 q/ha). Maximum net return of Rs 185286/ha with cost benefit ratio of 1:4.00 was recorded in treatment combination T4 (150:80:60kg/ha + Poultry manure 5t/ha) (M4xF2).
