Study on Yield, Yield Parameters and Tuber Quality of (Orange Flesh) Sweet Potato (Ipomoea Batatas. L.) Cultivars
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 6
Abstract
An experiment was conducted on seven oranges fleshed sweet potato cultivars at Central Agricultural University, Imphal, Manipur during kharif season 2014, under rain fed condition. The tuber yield, tuber yield parameters and tuber quality were evaluated. The experiment was laid out in randomized block design with three replications. The results of the experiment revealed that among the seven entries of sweet potato, CIPSWA-2 produced highest tuber yield (37.09 t ha-1) and the marketable tuber yield of (444.48 g plant-1), which was statistically at par with IGSP-15 (36.46 t ha-1) and (436.32 g plant-1) respectively, of the fresh tubers the starch content was found to be greater in CIPSWA-2 (24.53%) and carotene content was recorded highest with a value of (7.67mg100g-1) in ST-14 which was followed by CIPSWA-2 (4.43mg100g-1). The cultivars CIPSWA-2 and IGSP-15 proved to be superior with respect to yield and yielding parameters and performed well producing quality tubers and can be recommended for cultivation.
