| Abstract:
Experiments were carried out for 7 to 12 years with some tropical fruit crops commercially important in West Bengal, India to find out the optimum plant density. The results of the experiments are summarised hereunder: Pineapple: In cv. Kew, plant density of 64,000/ha is found optimum considering the yield (84.18 tonnes/ha) and fruit quality, further increase in density reduce the fruit quality and canning ratio. Banana: The optimum yield (36.8 tonnes/ha), size and quality of fruit incv. Giant Governor were obtained in a plant density of 2500/ha. Papaya: A plant to plant spacing of 2m x 2m (2500/ha) incv. Ranchi showed significant increase in yield (95.0 tonnes/ha) compared with 3m x 3m (1111/ha), without affecting the fruit size and quality. Guava: Increasing plant density above 400/ha in cv. L-49 markedly reduced fruit size and increased fruit acidity. The optimum density was found to be 278 plants/ha. Litchi: Observations over a period of 9 years revealed that spacing of less than 8m x 8m (156/ha) is not suitable for litchi cv. Bombai in warm humid climate. | |
