Water Deficit Implication on the Growth Attributing Characters of Some Selected Improved Banana Germ

A field experiment with ten banana germplasm, viz., was conducted at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during 2014-2016. Gobin Tulchi (AAB), Manohar (AAB), Bogimonohar (ABB), Agnisagarar (ABB) (AAA). In order to test the physiological performance of this banana (Musa spp.) germplasm with special regard to moisture tension, Barjahaji (AAA), Kachkal (ABB), Assamese Malbhog (AAB), Chenichampa (AAB), Bharatmoni (AAB) and Jahaji (AAA) After planting, the various parameters were reported in the 5th, 7th and 9th months. The experimental field soil was acidic, well-drained and sandy loam in texture with low N and K available and medium P available. Randomized block architecture was the statistical blueprint. All data relating to the present investigation were statistically analysed in accordance with the method of variance analysis (ANOVA) provided by Panse and Sukhatme (1967). The values of the vital difference (CD) were estimated at a probability level of 5 per cent. SPSS 7.5, Costat 6.3 and MS-excel were used for the analysis tools. The values of leaf area, root biomass, specific leaf weight, fruit length, fruit diameter, fruit filling size, number of hands per bunch, number of fingers per bunch, pulp-peel ratio and bunch weight were gradually reduced by moisture stress. The Barjahaji germplasm was found to be the highest yielder, followed by Bogimonohar and Agnisagar, while the Kachkal and Assamese Malbhog cultivars were found to be the lowest performers in this regard. It can be inferred from the above that the Barjahaji, Bogimonohar and Agnisagar cultivars are physiologically more tolerant.
