Effect of NPK on quality parameters of capsicum (Capsicum annuum L. var. Grossum) under protected condition

Abstract

The present investigation ‘Effect of NPK on quality parameters of Capsicum (Capsicum annuum L. var. Grossum) under protected condition’ was carried out at polyhouse complex, Department of Vegetable Science, College of Horticulture and Forestry, Pasighat, Arunachal Pradesh in the year 2017-2018. The experiment was carried out in factorial Randomized Block Design with 8 treatments which were replicated 3 times. Capsicum variety was taken up as the first factor i.e., V1-Asha (green var.) and V2-Bomby (red var.) and second factor were NPK (19:19:19) levels viz. T1-NPK@250 kg/ha, T2-NPK@300 kg/ha, T3 NPK@350 kg/ha and T4-NPK@400 kg/ha. Experimental results showed that the incorporation of the different NPK levels had a positive effect on quality parameters of the varieties. The higher total carotenoids content (4.30 mg/100gm) and ascorbic acid content (139.74 mg/100gm) was recorded in var. Bomby (V2) under T4 (NPK@400 kg/ha). The chlorophyll content was found more in var. Asha (1.81 mg/gm).
