Varietal Performance of Turmeric under Mango Based Agroforestry System

Abstract

An experiment was carried out at the Agroforestry and Environment Research Farm, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh, during April, 2014 to January 2015. The experiment was laid out in two factors Randomized Complete Block Design (RCBD) with three replications. Among the two factors, one factor like A was two production systems: S 1 = Mango + Turmeric and S 2 = Turmeric (sol e crop); another factor like B was three turmeric variety: V 1 = BARI Holud-1, V 2 = BARI Holud-2 and V 3 = BARI Holud-3. So, the treatment combinations were: S 1 V 1 = Mango + BARI Holud-1, S 1 V 2 = Mango + BARI Holud-2, S 1 V 3 = Mango + BARI Holud-3, S 2 V 1 = sole cropping of BARI Holud-1, S 2 V 2 = sole cropping of BARI Holud-2 and S 2 V 3 = sole cropping of BARI Holud-3. The result of the experiment revealed that interaction effect of production systems and variety was found significant on plant height, number of leaf per plant, length of leaf blade, breadth of leaf blade, number of finger per rhizome, fresh and dry yield per hectare. The higher fresh yield of turmeric (34.75 t/ha) and dry yield (6.10 t/ha) was found from S 1 V 1 treatment (Mango + BARI Holud-1). Whereas the lowest fresh yield (33.41 t/ha) and dry yield (4.93 t/ha) was found from S 2 V 2 treatment (sole cropping of BARI Holud-2). However, the suitability of the cultivation of different turmeric variety under mango based agroforestry systems may be ranked as S 1 V 1 > S 2 V 1 > S 1 V 3 > S 2 V 3 > S 1 V 2 > S 2 V 2 . Finally it may be concluded that, BARI Holud-1 would be the best variety to be grown under mango based agroforestry.
