Evaluation of Pointed Gourd (Trichosanthes dioica Roxb.) varieties by keeping using native pollinators boxes under Naturally Ventilated Polyhouse

Abstract:

In the current study, efforts were made to select suitable pointed gourd for polyhouse in the eastern part of India by using native pollinators. Growth and yield traits of five pointed gourd varieties were studied under polyhouse conditions for three years from 2018-19 to 2020-21. Among the five varieties evaluated under polyhouse production, the three years of pooled data revealed Rajendra Parwal-2 (52.89) was the earliest followed by Swarna Rekha (54.71) and KashiAlankar (53.65).KashiAlankar (6.11) produced the first flower at the lowest node number followed by SwarnaRekha (7.41) and Rajendra Parwal-2 (7.59), KashiAlankar (64.88) was the earliest in days to first harvesting followed by Swarna Rekha (65.47) and Kashi Alankar (58.13). Fruit length, fruit diameter, and average fruit weight was recorded maximum in KashiAlankar followed by SwarnaRekha. The number of primary branches recorded maximum with KashiAlankar (7.52) followed by SwarnaRekha (7.39) whereas vine length was recorded maximum with Swarna Rekha (7.76 m) followed by Kashi Alankar (7.58 m). SwarnaRekha variety recorded significantly superior over the rest of the varieties in terms of a number of fruit per plant (279.85), Fruit weight per plant (7.43 Kg), and Fruit yield per 1000 sq.m (3.45 t). So, it is concluded that SwarnaRekha variety was found suitable for production under naturally ventilated polyhouse condition in the eastern part of India.
