Abstract
The present investigation entitled “Integrated nutrient management studies in cauliflower
(Brassica oleracea var. botrytis L.)” was carried out at the Experimental Farm of College of
Horticulture and Forestry, Neri, Hamirpur (HP) during the Rabi season of 2020-2021 with the
objective to study the effect of integrated nutrient management on growth, yield, quality and
economics of cauliflower cv. PSBK-1. The experiment was laid out in a randomized complete block
design with three replications comprising of nine treatments in the plots having dimensions of 2.0 ×
1.4 m at a spacing of 60 × 45 cm. The best results for growth and quality parameters viz. days to
marketable curd maturity (113.33), plant height (74.76 cm), stalk length (8.04 cm), number of leaves
per plant (20.83), leaf length (48.75 cm) and dry matter content (10.98 %) were observed in plots
fertilized with treatment T8 (50% recommended dose of FYM + 50% recommended dose of sheep
manure + 50% RDF of NPK + fortnight application of jeevamrit @ 5%) followed by treatment T5
(Recommended dose of sheep manure (192q/ha) as basal dose at the time of field preparation + 75%
RDF of NPK + jeevamrit @ 5% (fortnight Application). The yield and its components traits viz. curd
depth (9.03 cm), curd diameter (13.19 cm), marketable curd weight (962.83 g), gross plant weight
(2.18 kg) and yield per plot (9.18 kg) also registered maximum values in T8 module. Best results for
soil pH (6.88), electrical conductivity (0.23 dSm-1) and organic carbon content (17.03 g/kg) were also
observed in module T8. The highest gross income (4,84,790 Rs/ha), net income (3,55,537.50 Rs/ha)
and cost: benefit ratio (1: 2.75) was also recorded with the treatment T8. No insect and disease
incidence were noticed during the course of investigation. Hence, module T8 (50% recommended dose
of FYM + 50% recommended dose of sheep manure + 50% RDF of NPK + fortnight application of
jeevamrit @ 5%) can be suggested as a cost-effective combination for getting higher yield on
sustainable basis.
