Response of potato (Solanum tuberosum L.) to the combined application of organic and inorganic fertilizers at Chena district, South Western Ethiopia

Low level or no use of organic and inorganic fertilizers serious imbalances soil nutrients, depressed potato yields pose accelerated mining native nutrients. Present on-farm studies was undertaken to observe the combined effects FYM compost along with fertilizers, particularly NPSB on production. The experiment comprised seven treatments: No fertilizer, recommended NP (115 kg N 92 ha-1 P2O5), P2O5, 6.5 S. 0.71 B ha-1), 10 tone ha-1, 5 + 50% (57.5 P2O5 were arranged in RCBD three replications. yield components collected subjected mean separation economic analysis. analysis variance indicated that either applied alone significantly (p ≤ 0.05) improved at Chena. Full dose each compost, rate gave similar yield. highest average marketable total fresh tuber (27.44, 27.92 t respectively) recorded by application ha-1) which is economically acceptable MRR (1239.7%), whereas lowest (14.45 obtained from unfertilized plot. Hence, proved best study area. Int. J. Agril. Res. Innov. Tech. 12(1): 18-22, June 2022
