Abstract
ABSTRACT
The present investigation entitled “Response of coloured capsicum to irrigation,
fertigation and organic formulation under protected conditions” was laid out in a CRBD with
three replications in a naturally ventilated polyhouse of an area of 200m2 at the Experimental
Research Farm of Precision Farming Development Center, Department of Soil Science and Water
Management of Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan.
Seeds of variety Orobelle (coloured capsicum) were planted in March in plug trays and transplanted in
UV stabilized polybags during April, in the year 2019 under polyhouse conditions. Soilless medium
comprising of sand + vermicompost (70:30 w/w) was used. The treatments comprised of two levels of
irrigation (D) viz. D1: Irrigation at 100% ETc, D2: Irrigation at 80% ETc and three levels of fertigation
(F) viz. F1: Fertigation at 100% RDF, F2: Fertigation at 75% RDF and F3: Fertigation at 125% RDF
along with two levels of jeevamrut (J) viz. J1: Jeevamrut application at 5% foliar spray and J0: Non
application of jeevamrut. The observations were recorded on crop parameters like plant height (cm),
days to 50% flowering, fruit length (cm), fruit breadth (cm), fruit weight (g), number of fruits per
plant, harvest duration (days), fruit yield per plant (kg), plant biomass (q/ha), and soil parameters like
available NPK (kg/ha), nutrient content (%), nutrient uptake (kg/ha), fertilizer use efficiency (kg/kg
nutrient). The analysis of variance showed significant differences among the treatment combinations
for majority of characters studied. The best treatment recorded 39.26, 60.06, 185.39, 72.70, 179.74
and 76.96% increase in plant height, no. of fruits, fruit yield, N, P and K uptake, respectively as
compared to lowest yielding treatment. The B:C ratio was observed to be 2.55:1 under best treatment.
From the present investigation it can be concluded that the treatment combination D2F3J1 having
irrigation at 80% crop evapotranspiration (ETc), fertigation at 125% recommended dose of fertilizers
(RDF) along with foliar application of jeevamrut is best suited for coloured capsicum production
under protected conditions.
