Influence of Inorganic Fertilizers in Conjunction with Organic Manures on Growth, Yield and Quality of Broccoli (Brassica oleracea var. Italica)

Abstract

A research work was conducted in the research farm of Nalanda College of Horticulture, Noorsarai, Nalanda (Bihar-803113) during Rabi season of academic year 2021-22 to study the Influence of Inorganic Fertilizers in conjunction with organic manures on growth, yield and Quality of Broccoli (Brassica oleracea var. Italica) in a randomized block design with 11 treatments. The Treatment, T5 (50% RDN + 50% N as PM) recorded maximum values for plant height (37.41cm and 56.13 cm), number of leaves per plant (16.53 and 20.11), leaf area (749.51cm2 and 949.57 cm2) at 45 DAT and 60DAT respectively. The treatment, T5 also recorded least days for head initiation (44.60 DAT) and highest value for diameter of head (15.93 cm), length of head (14.97 cm), wt. of head/plant (407.16 gm), wt. of head/plot (16.29Kg.), wt. of head/ha (150.65q.), vitamin C (92.43 mg/g), dry matter (11.57%), gross returns (Rs. 4,14,287.50/ha) and net returns (Rs. 3,19,448.00/ha) with B:C ratio of 3.36. This was followed by treatment T4 (50% RDN + 50% N as VC). Among all the treatments, the Treatment T5 (50% RDN + 50% N as PM) was found to be the best for obtaining better growth and optimum yield. Regarding qualitative characters and better soil health, treatment T4 (50% RDN + 50% N as VC) performed well.
