Abstract

In order to investigate the effect of organic and inorganic nitrogen fertilizer rates on growth, yield and tuber quality of potato (Solanum tuberosum L). Two field experiments were accompanied through 2014 and 2015 seasons on a potato plant cv. Alpha This investigation included four farmyard manure rates (0, 5, 10 and 15 tons/ha) and four mineral nitrogen rates (80, 120, 160 and 200 kg N/ha). Results revealed that increasing farmyard manure rates up to 15 tons/ha meaning fully improved height of plant, dry weight g/plant and No. of tubers/plant, tuber weight g/plant, tuber yield t/ha. TSS%, tuber dry matter%, carbohydrate % and ascorbic acid (mg/100g-1)by 4.97, 17.84, 25.17, 18.64, 24.07, 8.62, 29.86, 6.89 and 14.35%, respectively, comparing without farmyard manure as average of both seasons. Whereas, increasing mineral nitrogen rates up to 200 kg N/ha. significantly increased plant height, dry weight g/plant and No. of tubers/plant, tuber weight g/plant, tuber yield t/ha, TSS%, tuber dry matter%, carbohydrate % and ascorbic acid (mg/100g-1)by 4.26, 4.75, 8.85, 5.66, 12.59, 5.73, 8.43, 11.0 and 5.67%, respectively compared with fertilizing at 80 kg N/ha. as an average of both seasons. The highest yield/ha was produced due to the interaction by application of highest both of farmyard manure rate (15 ton/ha.) and mineral nitrogen rate (200 kg N//ha.). Conclusively, it possibly will be recommended that increasing farmyard manure to 15t/ha. and mineral nitrogen rate to 200 kg N/ha.for potato plants out yielded by 28.4 % more than without farmyard manure and addition 80 kg N/ha.
