Abstract: The experiment was conducted at Bore Agricultural Research Center on station for three consecutive years’ main cropping seasons with the aim to adjust planting date and fertilizer rate for Irish Potato production. Four level of fertilizer rate (0, 61.5, 82, and 114 kg Nitrogen and 0, 69, 92, and 115kg P ha-1 and planting date Immediately rain season (T1), 7days after rain (T2), 15days after rain (T3), 3 weeks later (T4). The treatments were arranged in RCBD in factorial arrangement with 3 replications. Tubers were planted on plot size of 4 m x 5m at spacing of 1m between plot, 1.5m b/n block, 70 cm between rows and 30cm between plants. The variety used in this experiment was Gudane. Based on the combined analysis of variance treatments over three consecutive years indicated that interaction effect of Planting Date and Different Fertilizer Rate significantly (P<0.001) affected Days to 50% emergency, maturity, plant height, stem number, number of tubers, and fresh tuber yield. However, parameters days to flowering and average tuber weight are non-significant (P<0.05) difference between each treatment means. The combined effect of immediate planting date (T1) with control (no nutrient) treatment (R1) recorded shortest (9.55 days) to emergency and early days to maturity (104.22days). And also regarding plant height the maximum (74.28 cm) plant height was recorded for treatment planted at first planting date with combined nutrient application of 114 kg N* 115 kg P. The interaction effect of immediate planting date with 82 kg N*92 kg P2O5 shows significant (P<0.05) maximum (9.1) stem number of potato. The maximum number of tubers (9.88, 9.66 and 9.44) was observed when tubers were planted at first week and applied with 82 kg N+92 kg P; 114kg N+115 kg P and second week with 82 kg N+92 kg P of fertilizer rates respectively. The highest Total tubers yield (41821 kg ha-1 and 41395 kg ha-1) were obtained from T1R3 (Immediate planting with combined nutrient of 82 kg N* 92 kg P2O5) and T2R3 (Immediate planting with combined nutrient of 82 kg N* 92 kg P2O5) respectively.

Abstract: The field experiment was conducting during 2016/17 cropping season at angecha testing site of Areka Agricultural Research center, southern Ethiopia to evaluate the effect of blended fertilizer on yield of wheat with the treatments of seven replicated three times across farmers in RCBD design. An approximate geographical coordinates of the testing site is 7o 0’ N latitude and 38o 29’E longitude having an altitude of 2381meteres above sea level. The treatments were control (no fertilizer), three rates of NPS (46N, 54 P2O5, 10 S; 69N, 72 P2O5, 13 S and 92N, 90 P2O5, 17 S,) and three rates of NPSCu (T2 + Cu; T3 + Cu and T4 + Cu). The plot size was 4 m by 4 m (16m2) and the spacing between plots and blocks was 50 cm and 100 cm, respectively. The result of this experiment also has substantiated the importance application of on yield of wheat NPSCu (combination of Cu with macronutrients NPS) fertilizers in improving yield of wheat in Angecha woreda. Despite the need of verification in multi-locations and soil types for wider use, application of NPSCu can be recommended for wheat production in the study area.
