Contributions of Growth and Physiological Traits to Yield of Seven Bambara nut Landraces Grown Under the Tropical Humid Climate of Malaysia
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 1
Abstract
Six introduced bambara nut landraces from Nigeria and one adapted variety from Malaysia were evaluated for their growth and yield characteristics in the tropical humid climate of Malaysia. Dry matter yield was correlated with number of leaves, plant height, leaf chlorophyll content, leaf area index, and total leaf area. While pod yield was correlated with days to 50% emergence, days to 50% flowering, number of flowers per plant, number of pods per plant and fresh pod weight per plant. Path analysis indicated that partitioning into direct and indirect effects resulted to total leaf area (r2 = 0. 62) imparting a significant direct influence on dry matter yield. Similarly, fresh pod weight per plant (r2 = 0. 50) has a high direct effect on pod yield. Leaf area index (r2 = 0.47) and total leaf area (r2 = 0.65) were both significantly correlated with dry matter yield while fresh pod weight per plant (r2 = 0. 63) and number of pods per plants (r2 = 0.48) has a significant correlation with pod yield. Fresh pod weight per plant and total leave area being a higher contributor to pod yield and dry matter yield of bambara nut respectively indicated their superiority to be selected for bambara nut improvement in the humid tropical climate of Malaysia.
