Abstract
This study was conducted in Dang district during 15 January 2015 to 12 June 2015. 25 soil samples were collected from 3 different nutrient management practices (T1- with chemical fertilizers only; T2- with IPNM; and T3- with organic manure only) for soil analysis. The comparative study of soil physical parameters i.e. soil texture, soil chemical parameters i.e. pH, OM, N, P and K content of all soil samples was done. The mean soil texture of all soil samples was found to be sandy loam. The value of N, P, K and OM was found higher in T3 thanT1. The mean pH value of T1 was 6.3, T2 was 6.65 and T3 was 6.7 where, differences in pH value between T1 & T2 as well as T1 & T3 were statistically significant at p≤ 0.05. Similarly, the mean value of OM was found to be 4.66% in T1, 4.25% in T2 and 6.62% in T3. Difference in OM content between T1 & T3 as well as between T2 & T3 were significant at p≤ 0.05. The mean value of total N was found to be 0.052% in T1, 0.071% in T2 and 0.092% in T3. Difference in N content between T1 & T3 was statistically significant at p≤ 0.05. Similarly, the mean value of available P was found to be 22.48 kg ha-1 P2O5 in T1, 38.42 kg ha-1 P2O5 T2 and 37.446 kg ha-1 P2O5 in T3. Differences in P content between treatments were not significant statistically. Mean value of K was found to be 286.83 kg ha-1 K2O in T1, 286.83 kg ha-1 K2O in T2 and 554.74 kg ha-1 K2O in T3. Difference in K2O content between T1 & T2 as well as between T1 & T3 were significant at p≤ 0.05. The study was found that fertility status of organic field was found to be better in term of fertility and OM content than inorganic fields.
