Abstract

The Present investigation was conducted during summer season, 2018 at DAV University, Jalandhar to determine most suitable variety and plant spacing for optimum production of okra in Jalandhar region. The treatments consisted of three plant spacings (30 × 5cm, 30 × 10cm, 30 × 15cm) and two varieties viz., Arka Anamika and Jammu Okra 05 laid in Factorial Randomized Complete Block design with three replications. Characters studied were days to 50% flowering, number of fruit per plant, number of fruit per plot, fruit yield per plot (kg), fruit length (cm), fruit diameter(cm), number of ridges per fruit, number of leave per plant and plant height(cm). Results obtained revealed that spacing and varieties has played paramount role in deciding the yield and yield contributing traits of okra. Among the varieties and spacing studied in the present investigation Arka Anamika, and spacing 30 cm × 10 cm have performed superior for most of the characteristics under observation. While, spacing 30 cm × 5cm and 30 cm ×15cm and variety of Jammu Okra 05 has manifested the undesirable results. The maximum number of fruits/plot, fruit length, plant height, number of leaves/ plant, number of fruits/ plant and total yield were witnessed at wider spacing 30 cm ×10 cm in variety Arka Anamika, while days to 50% flowering, fruit diameter was lowest in 30 cm × 15 cm in variety Arka Anamika.
