PERFORMANCE OF WHEAT VARIETIES AS INFLUENCED BY MANGO BASED AGROFORESTRY SYSTEM AND SPACING

Abstract

A field experiment was carried out at the Agroforestry and Environment Research farm, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur, during December 2013 to March 2014 to evaluate the performance of 3 (three) wheat variety under mango tree based Agroforestry system influenced by three different spacing. Wheat varieties were BARI GAM-25, BARI GAM-26 & Bijoy. The experiment was laid out in Randomized Completely Block Design RCBD with two factors with 3 replications. The wheat seeds were sown at three different spacing viz 15, 20 and 25cm in individual variety with two production systems namely wheat sole cropping and wheat + mango based production system. The data were recorded two broad heads, i) growth stage ii) harvesting stage. The data were analyzed statistically and means were adjusted by DMRT (Duncan’s Multiple Range Test). Plant height was found significantly higher after 45, 60 and 75 days under mango based system than open field. It did not vary significantly due to spacing but it varied significantly among the interaction treatments. Leaf &Tiller number did not vary significantly in production system and spacings. In case of interaction treatments leaf number did not vary significantly. But Tiller number varied significantly among interaction treatments. No variation was found in case of Leaf length. Leaf breadth was not also affected by production system& spacings. But it varied among interaction treatments. Spikelet length and number did not vary significantly in production system and spacings. But Spikelet length varied significantly among interaction treatments. Plant height of BARI GAM-26 did not vary significantly between mango based and open field system except after 30 days. Leaf number did not vary between production system and spacings. Leaf breadth and tiller number had no significant variation. Leaf length varied among interaction treatments only after 75 days. Spikelet length varied only in spacing and interaction treatments. Plant height of Bijoy varied significantly only after 60 days in production system, after 75 days in spacings, after 30 days among interaction treatments. Leaf and tiller number did not vary in production system and spacing but tiller number varied in interaction treatments after 75 days. Leaf length and Leaf breadth varied in production system and interaction treatments. Spikelet length varied among interaction treatments. Plant height varied significantly among the interaction treatments.1000 grain weight and yield per hectare varied significantly in production system and interaction treatments. Finally it may be concluded, mango tree intercropping increased wheat grain yield.
