Abstract
ABSTRACT A field experiment was conducted to assess the nutrients uptake pattern and partitioning of nutrient in banana cv. Rasthali (AAB) at critical growth stages like 10-leaf stage, 20-leaf stage, shooting stage and harvesting stage. From 10-leaf stage to harvesting, the per cent dry matter (DM) accumulation decreased from 43 to 22 in underground segment and increased from 57 to 78 in above ground segment. The sample was partitioned into root, corm, pseudostem, leaf lamina, petiole, peduncle, bunch and male bud, processed and analyzed for macro and micronutrients at different growth stages. The nutrient accumulation pattern with respect to dry matter production was worked out. To produce 38.8 ton banana per hectare, about 396 kg N, 69 kg P, 1044 kg K, 2.2 kg Cu, 5.3 kg Mn, 4.0 kg Zn and 6.5 kg Fe were taken up by banana cv. Rasthali. About 8 to 51% removal occurred through bunch harvest from the total nutrient uptake from the soil and remaining nutrients accumulated in the residual tissues were quantified and given.
