- Abstract
In order to maintain soil fertility, the knowledge of phosphorous fractions dynamics in soil is important for phospohorous fertlization and its uptake by plants. The experiment was set out in a randomized complete block design with nine treatments replicated thrice. Different P treatments such as control, inorganic P fertilizers, their combination with FYM, and pretreated compost based on 90 kg P2O5 ha-1 were applied to field plots. The statistical analysis showed that in comparison to alone P fertilizer, combining the application with FYM with DAP and R.P has significantly increased the grain yield and their components. DAP+FYM has produced maximum results as compared to all other treatments. It has increased the grain yield (kg ha-1), plant height (cm), pods plant-1, grains pod-1, 100 seed weight (g) and biomass yield (kg ha-1) by 39.7, 14.8, 24.3, 20.5, 22.1 and 39.4% followed by treatment amended with 2% R.P enriched compost. Grain yield showed a strong correlation with labile P (water-soluble and Ca2-P) and as well as with moderately labile (Al-P and Fe-P) with r values of 0.65, 0.51, 0.64 and 0.53, respectively, as compared to non-labile P in postharvest soils. The sole RP (rock phosphate) had higher non-labile P, which was significantly transformed into labile P by both mixing and pre-treatment of RP with FYM. This study demonstrated that P enriched compost can act as effective P fertilizer and can perform better than inorganic P fertilizer in terms of grain yield and yield traits of chickpea.
