Abstract
An investigation was conducted at Borjona village of Kapasia, Gazipur district during September 2011 to October 2012 to examine the biological performance of Indian spinach and papaya in litchi based agroforestry system. Papaya was planted between two litchi plants in each line and Indian spinach varieties were grown in the inter-space of two lines of litchi plant as well as control (farmers practice) in May 2012. Yield and yield contributing characters of Indian spinach varieties grown as litchi-papaya based agroforestry system and control did not vary. However, sprout plant-1 and sprout weight of Indian spinach varieties grown in litchi-papaya based system were significantly influenced while the other parameters did not vary. Sprout plant-1 of KS green (2.97) and local (2.89) variety were identical but higher over KS red variety (2.57). Sprout weight of KS red variety was the highest (85.80 g) while KS green and local variety gave lower and identical sprout weight. Though the yield did not vary among the varieties, KS red gave the highest yield (36.32 t ha- 1) followed by local (34.61 t ha-1) and KS green (34.00 t ha-1). In case of growth of litchi, plant height and stem diameter increment were 21.39 and 44.94 % over the eleven months observation period. The yield of papaya was quite satisfactory with an average 42 fruits per plant with 23.71 t ha-1. Therefore, in the Litchi-Papaya-Indian spinach based system, Indian spinach varieties could be ranked as KS red > Local> KS green.Int. J. Agril. Res. Innov. & Tech. 6 (1): 34-40, June, 2016
Highlights
Trees in and around homesteads, roads, crop fields and in forests play significant role in the livelihood of the people by providing fruit, timber, fuel wood, animal feed and the ecological stability of Bangladesh
At 125 DAS the studied parameters of Indian spinach varieties did not vary (Table 1 and Table 2) when they were grown in litchi-papaya based agroforestry system except, weight of sprout (Table 2)
Sprout weight of local variety was 84.97 g, which was significantly lower than sprout weight of KS red but higher than KS green (Table 2)
Summary
Trees in and around homesteads, roads, crop fields and in forests play significant role in the livelihood of the people by providing fruit, timber, fuel wood, animal feed and the ecological stability of Bangladesh. From the homestead trees and the cash earned through the sale of fruits and other tree products help the poor farmers to overcome the lean periods. Because of the relatively short juvenile (preproduction) phase of fruit trees, high market value of their products and the contribution of fruits to household dietary needs, fruit-tree-based agroforestry enjoys high popularity among resources limited producers worldwide (Bellow et al, 2008). Most example of fruit-tree-based Agroforestry has developed over long periods in response to interaction between agro ecological conditions, plant diversity and farmer resources and needs. Many of the practice such as jackfruit based system in Madhupur Tract, Date palm and Palmyra palm based system in Faridpur and
