Effect of Fertilizer and Inoculation on Phosphorus, Potassium and Sodium Content of Pot Culture Mature Soybean Seeds
Abdul Kabir Khan Achakzai and Safdar Ali Kayani

Abstract:
One year pot culture experiment on soybean cv.Williams-82 in Soil + FYM (3:1) was conducted in medium textured and salt free soil of Quetta, Balochistan. Seven fertilizer treatments were applied @ zero (control); 23; 25; 50; 75; 100 and 125 kg N ha G 1 plus a constant dose of 60 kg P2O5 and 30 kg K2O ha G 1 respectively (except control). These fertilizer doses were applied to both non-inoculated (non-inoc) and inoculated (inoc) pot culture crop. Results suggested that added fertilizer significantly and inconsistently influenced the PO4-P content, but negatively influenced the K content of mature soybean seeds. While reverse was true in case of Na contents. Results also revealed that by comparing the inoc with non-inoc treatments in particular doses of fertilizer, inoculation significantly increased the K and Na contents, but reverse was found for P contents. Statistically a maximum significant amount of P (6.86 g kg G 1) was recorded in T3 non-inoc dose of fertilizer (viz., 25 + 60 + 30 kg NPK ha G 1). While K (29.50 g kg G 1) and Na+ (7.667 g kg G 1) was noted in T2 inoc dose of fertilizer (viz., 23 + 60 + 30 kg NPK ha G 1). The simple correlation coefficient (r) values revealed that P content was significantly and positively correlated with starch (0.764), but negatively with oil contents (-0.448). While K (-0.839) and Na contents (-0.638) showed significant negative association with soluble sugars. It was also noted that grain yield pot G 1 established a significant negative association with K (-0.573), but non-significant with P and Na contents of mature soybean cv.Williams-82 seeds.
