A field experiment on soybean [Glycine max (L.) Meril] cv. Williams-82 was conducted in clay loam soil under the climatic conditions of Quetta with three level of N (i.e., 0.0, 2.5 and 50 kg ha-1) as urea, one level of N and P2O5 (i.e., 50 + 50 kg ha-1) as urea and SSP and one level of N, P2O5 and K2O (i.e. 50 + 50 + 50 kg ha-1) as urea, SSP and SOP respectively. These five fertilizer treatments were applied on .sowing both for non-inoculated (non-inoc) and inoculatgd (inoc) crop and latter designated as T1, T2, T3, T4, and T5 respectively. Results showed that in general plant height, number of nodes and branches and petiole length of both non-inoc and inoc were significantly and positively increased by added fertilizer over their respective control treatment (T1), but among various doses of fertilizer this increase was statistically non- significant. The moisture content of various plant organs were also significantly increased in both non-inoc and inoc treatments as compared with T1. However, this increase was comparatively significant in non-inoc over inoc treatments and maximum significant positive effect was recorded in T2 of non-inoc. Results further revealed that plots receiving 50 kg N ha-1 alone (non-inoc) resulted in highest grain yield (2565 kg ha-1) and it was significantly superior to all other NPK levels. It was also revealed that number of branches, leaf moisture content and number of pods plant-1 exhibited significant positive correlation with grain yield, which could be used a suitable selection criteria for predicting the grain yield in soybean.
