Effect of fertility levels and boron on growth and yield of cauliflower

Abstract

A field experiment consisting five levels of fertility and four levels of boron in RBD with three replications was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi season 2016-17. Results revealed that different fertility levels influenced growth, yield and quality of cauliflower significantly, plant height at 30 and 60 DAT, number of leaves par plant at 30 and 60 DAT and leaf area were recorded highest with application of 75% RDF through inorganic fertilizers and 25% RDF through vermicompost but remained at par with application of 50% RDF through inorganic fertilizer and 50% RDF through vermicompost. It is also revealed that average weight of curd volume, curd yield per plant and per ha (190.89 q/ha), were found highest with application of 50% RDF through inorganic fertilizers and 50% RDF through vermicompost treatment. Similarly, the boron level with 2.5 kg per ha significantly increased the plant height at 30 and 60 DAT, number of leaves at 30 and 60 DAT, leaf area at 30 and 60 DAT, average weight of curd, Curd yield per plant and per ha (185.53 q/ha), as compared to control and 1.5 kg boron per ha but statistically at par with 2.0 kg boron per ha.
