Abstract:
A field experiment was conducted during the Rabi season of year 2019-20 on potato with variety Kufri Ashoka to test the RDN levels (0, 100, 125%) with two organic manures (poultry manure and goat manure) at Research farm of Tirhut college of Agriculture Dholi, Muzaffarpur Bihar. The treatment combination were i.e. T1- control, T2 – 100% RDN through fertilizer, T3 – 125% RDN through fertilizer, T4 – 100% RDN through poultry manure, T5 – 100% RDN through goat manure, T6 – 50% RDN though fertilizer + 50% RDN through poultry manure, T7 – 50% RDN though fertilizer + 50% RDN through goat manure, T8 – 75% RDN through fertilizer + 25% RDN though poultry manure, T9 – 75% RDN through fertilizer + 25% RDN through goat manure, T10 – 100% RDN through fertilizer + 25% RDN through poultry manure, T11 – 100% RDN through fertilizer + 25% RDN through goat manure. The experiment was laid out in randomized block design and replicated thrice. The experimental site was sandy loam in texture, calcareous and slight alkaline in reaction (pH 8.31), low in organic carbon (0.40%), available N (212.55kg/ha), P2O5 (19.35kg/ha) and K2O (118.12kg/ha), respectively.

The experiment was laid out in randomized block design and replicated thrice. The experimental site was sandy loam in texture, calcareous and slight alkaline in reaction (pH 8.31), low in organic carbon (0.40%), available N (212.55kg/ha), P2O5 (19.35kg/ha) and K2O (118.12kg/ha), respectively.
All growth and yield parameter like per cent emergence, plant height, Number of shoots per plant, number of leaves per plant, dry matter accumulation, and bulking rate of tubers, yield attributes and yield were significantly influenced by the levels of RDN along with combination of poultry manure and goat manure. Among all treatments treatment T10 – 100% RDN through fertilizer + 25% RDN through poultry manure recorded higher per cent emergence (96.19), plant height (48.11cm), number of shoots per plant (6.29), number of leaves per plant (57.49), dry matter accumulation (70.68 g/plant), bulking rate of tubers (9.10g/plant/day), and tuber yield (274.75q/ha), total uptake of N (106.41kg/ha), P (24.51kg/ha) and K (122.88kg/ha) by crop and available N (223.86kg/ha), P2O5 (27.81kg/ha) and K2O (135.14kg/ha) in soil after harvest of the crop which was statistically at par with treatments, T3 (267.83q/ha) and T11 (272.48q/ha) and these three treatments were found to be superior over rest of the treatment.
In case of economic study, significantly higher B: C (3.30) was found under treatment T10-100% RDN through fertilizer + 25% RDN through poultry manure and was at par with treatments T3 -125% RDN through fertilizer and T11- 100% RDN through fertilizer + 25% through goat manure.
