Abstract

The experiment was, conducted during the 2019/2020 cropping season to investigate the yield and quality response of potatoes (variety Belete) to combined fertilization of farmyard manure and NPSB fertilizer in the Gewata district.

Four levels of FYM (0, 5, 10, 15 t ha-1) NPSB (0, 50, 100, 150 kg ha-1) blended fertilizer, was laid out in a 4×4 factorial randomized complete block design with three replications.

The mixed application of FYM with NPSB blended fertilizer significantly influenced (P<0.01) the tuber weight, marketable, unmarketable, total tuber, starch content and significantly (P<0.05) on specific gravity and nutrient use efficiency. The highest average tuber weight (99.33 g), marketable and total tuber yield (37.62 and 37. 9 t ha-1), specific gravity (1.09 g), starch content (17.83%) and the net benefit of Ethiopian Birr 325849.2 were recorded from the mixed, fertilization of 15t ha-1 FYM with 150 kg ha-1 NPSB blended fertilizer. Therefore, it can be concluded that the yield and quality of potatoes in the Gewata district, could be improved by mixed use of FYM (15 t ha-1) and NPSB blended fertilizer (150 kg ha-1).
