- W164129908 abstract "A field experiment was conducted to investigate the effect of different plant spacings on yield and fruit characteristics of okra (variety: Haritha). Treatments consisted of four plant spacings (90 x 60 cm, 60 x 45 cm, 45 x 45 cm and 45 x 30 cm) among which the spacing recommended (90 x 60 cm) by the Department of Agriculture served as the control. Treatments were arranged in a Randomized Complete Block Design with three replicates. Fertilizer was applied per plant basis as per the Department of Agriculture recommendation. Green fruits were harvested every two days and data on total yield (kg/ha), length of fruit (cm), weight of fruit (g) and number of fruits per plant were collected at each harvest. Total fruit yield, fruit length, fruit weight and number of fruits per plant were significantly affected by plant spacing. When compared to the control, total fruit yield increased by 35% and 160% at 45 x 45 cm spacing during the yala season and at 45x30 cm during the maha season. In contrast, the fruit length decreased by 11.6% at 45 x 45 cm during yala and by 11.3% at 45 x 30 cm during maha when compared to the control. During yala, single fruit weight decreased by 16% at 45 x 45 cm and by 16.5% at 45 x 30 cm spacing during maha when compared to the control. Number of fruits per plant decreased while total yields increased when compared to the control as plant population increased during both seasons. The study indicated that, a 45 x 45 cm spacing could be selected for the yala season while, a 45 x 30 cm spacing is appropriate for maha season for higher yields and quality fruits of okra. INTRODUCTION Okra (Abelmoschus esculentus L.), which originated in Asia and Africa, is one of the most important warm season fruit vegetables grown throughout the tropical countries. It is also recognized as one of the world’s oldest cultivated crops. It is a popular vegetable in Sri Lanka which ranks fourth in cultivated extent among the low country vegetables (Anon, 2007). It shows a wide adaptability and is cultivated in various regions of the country either as a home garden crop or on a commercial scale. It also shows vast potential for earning foreign exchange. The green, tender fruits of okra are rich sources of vitamins, calcium, potassium, and other minerals. If the crop is managed properly, okra produces green fruits continuously for several months. Factors which influence the crop yield include genetic and nutritional factors and space available to plants. Appropriate plant spacing can lead to optimum fruit 1 Field Crops Research and Development Institute, Mahailluppallama, Sri Lanka. 2 Department of Crop Science, Faculty of Agriculture, University, Peradeniya, Sri Lanka." @default.
