Abstract/ Executive Summary:

The experiment was conducted at the existing multistoried coconut orchard of the Horticulture Farm, Bangladesh Agricultural University, Mymensingh, to investigate the performance of lemon and guava grown under coconut based multistoried Agroforestry system during the period of January 2004 to August 2004. The experiment was laid out in randomized complete block design with five replications. Treatments were :T₁- comprises the combination of coconut + lemon based Agroforestry system, T₂- comprises the combination of coconut + guava based Agroforestry system, T₃- lemon in open condition., T₄- guava in open condition. In open condition lemon and guava received 100% sunlight; while coconut + lemon and coconut + guava based Agroforestry system received, 65-75% sunlight for the growth and development of lemon and guava. Multistoried Agroforestry systems under this study had showed significant influence on yield, yield attributing and quality parameters of lemon and guava. The result revealed that the highest plant growth and best yield contributing characters of lemon was found coconut + lemon based Agroforestry system. The highest plant height, number of leaves, flowers, fruits, harvested fruits, single fruit weight, total yield and TSS were obtained when lemon grown under coconut + lemon based Agroforestry system. But for the guava plant, the highest plant height, number of leaves, flowers, fruits, harvested fruits, single fruit weight and total yield were obtained when guava grown under open condition. The trend of total soluble solids (TSS) content of both lemon and guava in different treatments indicates that TSS content was decreased in full sunny place.

End Date: 00-08-2004

Program Area: Farming System

Commodity: Coconut, Guava, Lemon

Objectives:

1. To observe performance of lemon and guava in multistoried agroforestry system as middle layer crops.

Methodology:

The experiments were conducted in the existing multistoried coconut orchard of the Horticulture Farm, Bangladesh Agricultural University Mymensingh. The experimental site was situated under tropical monsoon climate and the soil texture was sandy loam with a pH of 6.6. The structure of the soil was fine and the organic matter content was 1.8%. The experiment was laid out following a Randomized Complete Block Design (RCBD) arrangement of multistoried production system. Four treatments were used in this study. Five replications were followed for each treatment. The treatments were randomly distributed within the field. Treatment of the experiment were as:T₁- comprises the combination of coconut + lemon based Agroforestry system, T₂- comprises the combination of coconut + guava based Agroforestry system, T₃- lemon in open condition., T₄- guava in open condition. Treatment T₁ was a two layered canopy configuration consisted of coconut and lemon. Coconut was at the top layer and aged 25 years. The second layer had lemon plants which were five years old and were in fruiting condition. This layer allowed falling 65-75% of light intensity. Similarly, treatment T₂ was also a two layered canopy configuration consisted of coconut and guava. Coconut plant was 25 years old and at the standing top layer. The second layer had guava plants which were five years old and were in full bearing condition. This layer also received 65-75% sunlight while in open condition treatment T₃ and T₄ plants received 100% sunlight. Light interception was measured with Lux meter. Lemon was harvested on June 2004 and guava was harvested on August, 2004 at matured stage. The yield parameters under study from all of the experimental plants of lemon and guava were recorded and then the data were statistically analyzed following ANOVA technique and means were adjusted by LSD test at 1% and 5% level of significance.

Achievement/Findings:

It is, therefore, concluded that the performance of lemon and guava as middle layer crops under coconut based multistoried agroforestry production system were different. Among the two fruits, lemon is more suitable than that of guava.
