Estimation of Soil Fertility Status under Sugar Cane-Wheat Farming System in Different Blocks of Rampur District of Uttar Pradesh

The present study was undertaken during 2015–16 to assess the soil fertility status under sugar cane-wheat farming system in different blocks of Rampur district of Uttar Pradesh. Six blocks namely Milak, Chamrauva, Bilaspur, Shahabad, Saidnagar and Swar were selected. The soil sample was taken from 0–15 cm depth with the help of augur and physical & chemical properties of the soil were analyzed. It was observe that 93.30 per cent samples were normal (6.5–8.5), 2.49 per cent were alkaline (pH > 8.5) and 4.20 per cent were acidic (pH <6.5). The organic carbon content in the soil of the district revealed that 35.38 per cent samples were less than 0.5, 51.07 per cent samples were ranged between 0.5 to 0.75 per cent and 13.15 per cent samples were more than 0.75 per cent. The nitrogen content in soil indicated that soils were low in nitrogen. 82.48 per cent samples were less than 280 kg/ha, 17.52 per cent samples were ranged between 280 to 560 kg/ha and no sample was found more than 560 kg/ha. In case of available phosphorus 6.8 per cent samples were less than 10 kg/ha, 74.38 per cent samples ranged between 10 to 24.6 kg/ha and 19.43 per cent samples were more than 24.6 kg/ha. Regarding potassium content, 97.55 per cent samples ranged between 108 to 280 kg/ha, only 2.10 per cent samples were found more than 280 kg/ha and 0.35 per cent samples were found less than 108 kg/ha.
