The present investigation entitled “Effect of integrated nutrient management on quality & yield attributes of sweet pepper (Capsicum annuum L.) cv. California.” was conducted at the experimental farm of Faculty of Agricultural Sciences & Allied Industries, Rama University, Mandhna, Kanpur (U.P.) during Rabi season 2018-19. The experiment was laid out in randomized complete block design with three replications comprising of 9 treatments combinations. The treatments were T0 = Control, T1: 100% RDF Nitrogen + vermicompost, T2: 100% RDF Nitrogen + FYM, T3: 100% RDF Zn + Nitrogen, T4: 100% RDF Phosphorus + FYM, T5: 100% RDF Potash + Boron, T6: 100% RDF Nitrogen + Phosphorus + Boron, T7 : 100% RDF FYM + Vermicompost, T8: 100% RDF Nitrogen + Zn. Plant height was recorded maximum in T6 (55.65 cm) and minimum was observed in T0 (30.75 cm), Number of branches/plant was recorded maximum in T6 (6.61) and minimum in T0 (3.40). Plant spread was maximum in T6 (44.50 cm) through recommended package of fertilization and minimum in T0 (25.35 cm). Maximum and minimum stalk length were observed in T7 (42.87 cm) and T1 (33.16 cm). Application of 100% RDF + Nitrogen+ phosphorus+ Boron in Sweet Pepper var. California proved to be the best treatment which produced superior growth and highest seed yield (686.39 q/ha).
