Effect Of Nitrogen And Potassium On Pomegranate Cv. Bhagwa Under Red And Lateritic Zone Of West Bengal

Abstract

The experiment was conducted with five levels of nitrogen and four levels of potassium per plant with twenty treatment combinations were applied to three years old pomegranate cv. Bhagwa trees at the Regional Research Sub-Station, Sekampur, Birbhum of Bidhan Chandra Krishi Viswavidyalaya, West Bengal. The highest yield was observed with N60 (4.103 kg/plant). In potassium application the yield /plant varied between 2.96 kg/plant (K0) to 3.664 kg/plant (K40). The combined application of N80K40 resulted in a 28.07 % (212.60g) increase in fruit weight compared to the control treatment (166.00g). The highest number of fruits/plants was recorded in treatment N60 (20.438) and lowest in control (13.688). Significantly maximum number of fruits /plants was noted in K40 (18.550). The highest increase in aril weight and juice weight could be observed with the application of N60K60 treatment. Quality analysis of the fruits showed maximum TSS with the 60 g/plant k. It is concluded that the combined application of N@60g and K@40 g per plant is beneficial in improving the yield and quality of three years old pomegranate plants under the red lateritic zone of West Bengal.
