Abstract:
A field experiment entitled “Effect of fertility levels on growth and fibre yield of tossa jute varieties (Corchorus olitorius L.)” was conducted during kharif season 2021 at Agriculture Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) to find out performance of varieties of tossa jute under different fertility levels. The experimental soil was clayey having slightly alkaline reaction, low available soil nitrogen, medium available soil phosphorous and high available soil potassium. The experiment consisted of two varieties (V1-JRO 204 and V2-JRO 2407) as main plot treatment and five different fertility levels (F0-Control, F1-60:40:40, F2-80:60:50, F3-100:80:60 and F4-120:90:70 kg NP₂O₅K₂O ha^-1) as sub plot treatment was laid out in split-plot design with three replications. Among the tested varieties, the variety JRO 2407 gave the maximum green biomass yield (138.18 q/ha^-1), Fibre yield (20.54 q/ha^-1), Stick yield (41.45 q/ha^-1), gross monetary return (Rs. 113130 ha^-1), net monetary return (Rs. 68606 ha^-1) and benefit: cost ratio (2.52) than variety JRO 204. Among the fertility levels, the highest green biomass yield (155.42 q/ha^-1), fibre yield (20.86 q/ha^-1), stick yield (45.01 q/ha^-1), net monetary returns (Rs. 68626 ha^-1) and benefit: cost ratio (2.44) was recorded with application of 120:90:70 kg NP₂O₅K₂O ha^-1 followed by 100:80:60 and 80:60:50 kg NP₂O₅K₂O ha^-1.
