Abstract:
The field experiment was conducted during kharif 2019 at Farm of Jute and Allied Fibre crops at Rahuri, Maharashtra on medium black soil to evaluate the yield potential and economics of newly released genotypes of roselle (Hibiscus sabdariffa L.). The experiment was laid out in Factorial Randomized Block Design during kharif season in four replications. The factor A consist of three varieties viz., V1- AHS 286, V₂- AMV-5 and V₃-HS-4288 and factor B consist of four fertilizer levels viz., F₀-Control, F₁- 40:20:20, F₂- 60:30:30 and F₃-80:40:40; N:P₂O₅ :K₂O;kg ha^-1_.This semi-arid tract with an annual rainfall received 693.8 mm and 43 rainy days during period experiment. The altitude varies from 495 to 569 m above mean sea-level. The results stated that, the variety AHS-286 recorded significantly higher growth and yield attributes viz., Plant height, number of functional leaves, fibre yield per plant than the variety AMV-5 and HS-4288. The variety AHS-286 recorded significantly higher green biomass and fibre yield (59.68 t/ ha, 23.79 q/ ha) than the variety HS-4288 (56.42 t/ha, 20.73 q/ha) and AMV-5 (51.15 t/ha, 20.01q/ha). Similarly, the variety AHS-286 recorded maximum gross (Rs.93962/ha), net (Rs.55921/ha) monetary returns and B:C ratio (2.45) than rest of all varieties. The application of fertilizer levels (N: P2O5:K2O) of 80:40:40 to the roselle crop recorded significantly higher green stalk and fibre yield (64.53 t/ha and 27.07 q/ ha) than fertilizer levels of control and 40:20:20 kg/ha but it was at par with fertilizer levels (N:P₂O₅:K₂O) of 60:30: 30 kg/ ha (63.29 t/ha and 26.03 q/ha). So, Its beneficial effects recorded to increase economic indices viz., net returns (Rs.66185/ha) and per rupee returns (2.64) of application of fertilizer levels (N:P₂O₅:K₂O) of 60:30: 30 kg/ ha than rest of all treatments. It is concluded that, performance of newly released genotype of AHS-286 with fertilizer level of 60:30:30 (N:P₂O₅:K₂O) kg/ha is beneficial for higher fibre yield and economic returns of roselle (H. sabdariffa) in kharif season.
