ABSTRACT
This study was performed to estimate the efficacy of organic substrates to release, solubilize and improve uptake of phosphorous using wheat as test crop. The research was steered through completely randomized design (CRD) with 14 treatments and 06 replications. Pre and post-harvest soil analysis was performed. The results showed maximum increase in nitrogen (N) (0.91 ppm) and potassium (K) contents (2.59 ppm) in wheat crop and maximum increase in all plant parameters were recorded in T11 [T2 + all P from PROM (phosphorus rich organic manure)] followed by T13 (T2 + all P from phosphocompost). In case of soil characteristics, application of recommended NPK from chemical fertilizer (T2) recorded the highest pH (8.66) of soil, while the maximum EC (2.75 dS m-1) of soil was noted under the application of (T13) (T2 + all P from compost). Soil organic matter (0.90 %) was found to be maximum under T5 (T1 + all P from phosphocompost), while the treatments T11 (T2 + all P from PROM) and T4 (T1 + all P from FYM) noted the maximum levels of P (8.0 ppm) and K (3.45%) in soil, respectively. Conclusively, all the treatments significantly improved the soil characteristics and nutrient concentration of wheat plant compared to control (T1). Use of phosphocompost proved very useful to enhance soil health and consequently nutritional characteristic of wheat crop.
