ABSTRACT
Field experiment was conducted at Agronomy Research Fields, School of Agriculture, Lovely Professional
University, Phagwara (Punjab) during 2021-22 to find out the effect of spacing on toria growth and yield at various nutrient levels for enhancing productivity. The experiments were laid out in factorial randomized block design with three replications. The treatments comprised with two spacing viz., 45 × 15 and 30 × 10 cm and four levels of fertilizers: 0, 75, 100 and 125% RDF. The planting material used in study was TL 17. Plant spacing and different nutrient levels together influenced the growth and yield of toria. Optimum spacing with a recommended dose of fertilizer (30 × 10 cm+100% RDF) recorded the highest plant height, fresh weight, dry weight, leaf area, CGR, RGR, number of branches than other spacing and
fertilizer levels. Integration of crop geometry at 30 × 10 cm 100% RDF proved to be a better crop management alternative than 45 × 15 cm+100% RDF for sustained production of toria under irrigated conditions in sandy loamy soils of Punjab Region.
Key words : Fertilizers, spacing, RDF, toria, oil recovery yield, protein yield
