Abstract:
A field experiment was carried out under naturally ventilated polyhouse during 2020-21and 2021-22 at Zonal Agricultural and Horticultural Research Station (ZAHRS), Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences (KSNUAHS) Navile, Shivamogga. The experiment consisted of 4 treatment combinations with 6 replications in CRD design. The treatments included four levels of fertilizer application viz. 50%, 75%, 100% RDF through fertigation and 100% RDF through soil application. Water applied was common for all the treatments and it was 100% crop ET. The highest crop yield was recorded in the treatment receiving 100% crop ET with 100% RDF through fertigation. i.e., 111.70 t ha^-1. The water use efficiency was highest in treatment consisting of drip irrigation at 60% crop ET and nutrient use efficiency was highest in the treatment receiving 100% crop ET with 100% RDF through fertigation (587.89 kg ha^-1).
