Abstract
An experiment was conducted at the Agroforestry Model Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur during May to Dec 2007 to study 11 vital yield traits, yield and quality of a local variety of ginger cultured under three Agroforestry systems, i.e. beneath the shades of three multi-use tree species (2.5 years old) and also in the open field. So, the four treatments were: Open field having no shade vis-a-vis full sunlight (T1 control), under guava trees with 70±5% shade (T2) below black siris trees providing 60±5% shade (T3) and underneath mango trees having 50±5% shade (T4). The trial was set in the Randomized Complete Block Design. Eleven vegetative traits (plant height, number of leaves per plant, number of tillers per plant, leaf size, number of finger per plant, finger fresh weight per plant, finger dry weight per plant, rhizome fresh weight per plant, rhizome dry weight per plant rhizome yield per plot and rhizome yield per hectare) were investigated. Of them, ten were statistically remarkable while only the number of leaves per plant was trivial. The ginger-mango partnership (T4) having 50±5% shade resulted the plant growth of medium status but had the topmost yield of ginger (12.42 t/ha, which was 2.45 fold better than the least yield (5.07 t/ha) of the ginger-guava coalition (T2) and 119.65 times higher even from the from the open field (T1). The yield of ginger (rhizome + finger) was in the sequence mango (119.65) > open field (100.00) > black siris (75.05) > guava (48.84%). Finally, all the coefficients of correlation for 55 partnerships of 11 traits ranged from 0.37 to as high as 0.99. It is interesting to note that all of those values were positively momentous. Nonetheless, only four companionships, e.g. number of rhizomes per plant, rhizome fresh weight per plant, rhizome dry weight per plant and number of fingers per plant with the leaf size were considerable at 5% altitude of possibility. Contritely, the remaining values for 51 coalitions were noteworthy at 99% level of confidence.
