Abstract:

The present studies entitled “Rootstock effects on seasonal nutrient dynamics and horticultural characteristics in some exotic apple cultivars” aimed to investigate differences of nutrient concentrations among different exotic cultivars on various rootstocks growing in the same conditions. During the investigation it was observed that leaf nutrient concentrations significantly varied with rootstocks during both the seasons. The exotic cultivars like Vista Bella on MM106 recorded highest leaf P (0.21, 0.20%) and highest K content (1.54, 1.55%) recorded in Starkrimson on both rootstocks. However, the maximum Mg content (0.30, 0.30%) was observed in Cooper IV on both rootstocks. Similarly lower concentration of P and potassium content (0.16, 0.15%) and (1.47%) recorded in Cooper IV, and minimum Mg nutrient content (0.25, 0.27%) recorded in Vista Bella indicating a definite effect of rootstocks on translocation of nutrients within the plant system. The seasonal variation of leaf nutrient concentrations during growth period indicate that early maturing cultivars viz., Vista Bella and Mollies Delicious recorded increase in nutrient content upto 30th of June, thereafter the trend decreased, while as the mid-season cultivars like Starkrimson and Cooper IV observed a similar trend upto 15th of July and decreased thereafter. The seasonal variation of nutrients in leaves indicate stability period of various nutrients like P, K and Mg in early maturing cultivars like Vista Bella and Mollies Delicious from 15th of June to 15th of July, while as in mid-season cultivars Starkrimson and Cooper IV the stability in nutrient concentration was recorded from 30th June to 30th of July indicating the appropriate leaf sampling period for these exotic cultivars as against the sampling time of existing cultivars which is from mid-July to mid-August under similar conditions.
