Abstract
Growing potatoes requires great care because it needs large nutrients. Proper fertilization is a critical aspect of improving yield. This study comprises a field experiment to assess the impact of several fertilization approaches on the crop performance of potato (cv. Montreal). In this context, we used eight distinct fertilizer treatments: control (T0), standard mineral fertilizer (T1), substance mushroom spent (T2), cow + poultry manure (T3), compost (T4), 50% standard mineral fertilizer comprising substance mushroom spent (T5), 50% standard mineral fertilizer augmented with cow + poultry manure (T6) and 50% standard mineral fertilizer augmented with compost (T7). The results indicate that control treatment gave least days to mean germination time. While the standard mineral fertilizer (T1) had the highest values in chlorophyll content in leaves, single tuber weight, tuber count per plant, and plant yield. On the other hand, (T6) showed significant increment in number of tubers per plant. Meanwhile, (T7) treatment produced higher marketable yield and tuber per plant. Whereas, there are not significant difference among treatments in number of arial stems. on the other hand, these results were the lowest for the control treatment. Hence, the fertilization approach extensively impacts vegetative development and tuber yield.
