Abstract/ Executive Summary:

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 (farmer’s 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.

Keywords: Indian Spinach, Papaya, Litchi based agroforestry system

Location: Kapasia thana in Gazipur district, Bangladesh

Start Date: 00-09-2011

End Date: 00-10-2012

Program Area: Farming System

Commodity: Litchi, Papaya, Spinach

Objectives:

To study the growth and yield of Indian spinach and papaya in litchi-papaya-Indian spinach based agroforestry system
To observe growth of litchi in litchi-papaya- Indian spinach based agroforestry system.

Methodology:

The study was carried out in a one year old litchi orchard at Borjona village under Kapasia thana in Gazipur district from September 2011 to October 2012. First of all a litchi (China-3 variety) orchard was established by transplanting one year old litchi saplings in October 2011 and about one month old papaya (Shahi variety) seedlings were planted between two litchi plants in each line in January 2012. Indian spinach varieties were grown in the inter space of two lines of litchi plant in May 2012. Three Indian spinach varieties (KS Green, KS Red, and local) were grown in the inter space of two lines of litchi and papaya plants. Seeds of Indian spinach were sown on slightly raised beds between lines of litchi and papaya plants. These three varieties were the treatment of the experiment. The experiment was laid out in one factor Randomized Complete Block Design (RCBD) with five replications. Treatments were randomly allotted in each block. In each plot there were 9 rows accommodating 18 plants row-1. The size-of the unit plot was 5.6 m × 4.1 m = 22.96 m2 and plant to plant and row to row distance was 30 cm × 45 cm respectively. Data was collected from five representative plants of Indian spinach at 15 days interval starting from 50 to 125 DAS. Data on number of sprout plant^-1, number of leaves sprout^-1, length of stem at harvesting, stem diameter at harvesting, yield plot-1 and yield (t ha^-1) were recorded. For papaya data on plant height, stem diameter, fruit length, fruit diameter and yield were recorded. For litchi, data on plant height and plant diameter were recorded. Stem and plant diameter of papaya and litchi was measured at 30 cm above from the ground level. Data were statistically analyzed using the Analysis of Variance (ANOVA) technique with the help of computer package MSTATC to examine the significant variation of the results due to different treatments. The mean differences were adjusted by Least Significant Different (LSD) at 5% level of significance.

Achievement/Findings:

The findings from the investigation stated that, yield and yield contributing characters of Indian spinach varieties between litchi-papaya based system and control does not vary much. In litchi- papaya based system, the tested three indian spinach varieties responded differently. Sprout plant^-1 and sprout weight were significantly influenced system while the other parameters did not vary. 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). The plant height and stem diameter increment of litchi plant were 21.39 and 44.94 % over the initial in ten months observation period and production of papaya was satisfactory with an average of 42 fruits plant^-1 with 23.71 t ha^-1 yields. Regarding selection of Indian spinach varieties it could be ranked as KS red > Local> KS green.
