Abstract

Currently being conducted is a study with the “Interaction of varieties, planting dates, growth regulators on the yield and quality of Dolichos Bean (Lablab purpureus L.) under shade net instances” was carried out during summer at Horticultural Research Station, Ambajipeta, East Godavari District of Andhra Pradesh. A Factorial Randomised Block Design (FRBD) with 36 alternative treatment combinations that were each replicated three times in an open field was used to design the experiment. Four distinct varieties, including Arka Jay, ArkaAmog, ArkaSambhram, and ArkaSowmya, were used in the experiment. The sowing dates were December 15, January 1, and January 15, and the growth regulators used were NAA 25 ppm, Triacontanol 2 ppm, and control. The yield and quality metrics were collected, and the data were statistically analysed using ANOVA. Highest pod yield (237.72 g) was recorded in ArkaSowmya (V4) followed by ArkaSambhram (V3) (216.65). Arka Jay (V1) recorded the lowest pod yield of 172.83 g. Dates of sowing also showed significant influence on pod yield per plant. Highest pod yield was recorded in January 1st sowing (S1) (232.68 g), followed by January 15th sowing (S3) (194.83 g). Highest pod yield was recorded in Triacontanol 2 ppm (G2) (226.30 g), followed by NAA 25 ppm (G1) (208.75 g) and without spray (control) (G3) (186.26 g). The highest shelling per cent of fresh pod (35.63) was noticed in Arka Jay (V1) and it was on par with ArkaSambhram (V3) (34.16 %). The highest shelling per cent of fresh pod was observed in January 1st sown crop (S2) (35.18 %), followed by December 15th sown crop (S1) (34.58 %). Highest shelling per cent for fresh pod was recorded in Triacontanol 2 ppm (G2) (36.44), followed by NAA 25 ppm spray (34.66). Growth regulators showed significant effect on protein content. The field bean crop sprayed with NAA 25 ppm foliar spray recorded the highest protein of 15.35 per cent followed by Triacontanol 2 ppm foliar spray(14.42%). Highest fibre content (33.69 %) was recorded in NAA 25 ppm spray (G1) and it was on par with Triacontanol 2 ppm (G2) (33.56 %). With a pod yield of 293.90 g, ArkaSowmya, which was planted on January 1st with Triacontanol 2 ppm spray (V4S2G2), had the highest yield.

Conclusion

Arka Sowmya which was planted on January 1st with Triacontanol 2 ppm spray (V4S2G2), had the highest yield under shade net.
