ABSTRACT
The influence of plant spacing on the growth and seed production of okra varieties was studied at the Horticulture Farm of the University of Agriculture, Peshawar during spring seasons of the years 2012-13. The research experiment was conducted using RCB Design with 2 factors and 3 replications. Five okra varieties viz. Sabz Pari, Arka Anamika, Pusa Sawani, Punjab Selection and Green Star were grown at three plants spacing i.e. 20, 30 and 40 cm and were evaluated for growth and seed production. Variety Arka Anamika had the maximum plant height (136.8 cm), number of branches per plant (1.42), number of pods per plant (26.33), number of seeds per pod (60.67), seed weight per pod (3.87 g) and seed yield (4.54 t ha-1). The plant spacing of 20 cm resulted in the maximum plant height (136.92 cm) but minimum values for all other attributes. 40 cm plant spacing resulted in the maximum seeds per pod (67.28), seed weight per pod (4.61 g), hundred seed weight (6.87 g) and seed yield (4.42 t ha-1). The okra varieties and plant spacing interaction was significant for seed weight per pod only. In conclusion, 40 cm plant spacing can be recommended for optimum seed production in okra.
