PERFORMANCE OF PINEAPPLE AND ITS QUALITY AS AFFECTED BY MULTISTORIED AGROFORESTRY PRODUCTION SYSTEM

Abstract

An Experiment conducted at the Germplasm centre, Fruit Tree Tmprovement Project, Bangladesh Agricultural University (FTIP-BALI-DH), Mymensingh, during the period of May 28, 2002 to August 30, 2003 to determine the production and quality of pineapple (var. Giant Kew) as affected by different mulcistoried agroforestry systems. Different multilayered agroforestry production systems under study were: sissoo guava + pineapple, sissoo ~ lemon ~ pineapple, mango 4- guava + pineapple, coconut - guava - t- pineapple, coconut + lemon + pineapple and a control pineapple plot. Different multistoried agroforestry systems under this study had showed significant influence on yield, yield attributing and quality parameters of pineapple. Considering the effect of shade on yield without crown (27.08 tiha) different multistoried tree combinations showed statistically similar trend, but when total yield compared with control plot, it showed significant difference. The highest fruit set (82.23%), individual fruit weight (0.96 Kg), fruit size (42.28 cm), L/B ratio (1.31), pulp of fruit (0.46 kg), pulp-peel ratio (2.35) and edible portion (70-05%) were obtained when pineapple grown under sissoo - lemon based agroforestry system where light intensity was 22.99% i.e., under partial shade. An increase in peel of fruit (0.22 kg). length / breadth ratio (1.26), total yield with crown (38.44 t/ha), moisture content (81.05%). total titratabie acidity (0.59%) and decrease in total sugar (9.53%), edible portion (65.51%) pulp-peel ratio (1.96) were observed, when pineapple grown under mango guava based agroforestry system with 13. 45% noon time light intensity i.e., in full shady place. Under control condition (86.30% light intensity) fruit size (35.38 cm), fruit weight (0.77kg), pulp of fruit (0.36 kg). total yield with (32.19 t/ha) and without crown (23.44 t/ha), length of fruit (24.38 cm), edible portion (64.86 0 /'o) were decreased with increase of light intensity and increase in TSS / acidity ratio (38.79) and pH (5.16).
