ABSTRACT
The study was conducted on two different sowing dates in response to various level of added N fertilizer on the uptake of PO4 -P, K and Na content of mature soybean cv. Williams-82 seeds. Seven fertilizer treatments were applied to both non-inoculated (non-inoc) and inoculated (inoc) crop. Fertilizer treatments significantly increased the K and Na content of early planting, but decreased in late plantings, while P content is significantly reduced in both plantings when compared with their control treatment. Statistically a maximum significant amount of K is recorded in T7 (22.70 g kg-1) and Na in T6 (9.667 g kg-1) level of fertilizer. Result also showed that by comparing the inoc with non-inoc in particular doses of fertilizer, inoculation in general significantly increased the P and K content of both plantings and Na of early plantings. Statistically a maximum significant level of P, K and Na is recorded in T2 (4.997 g kg-1), T4 (28.02 g kg-1) and T2 (7.767 g kg-1), respectively. Results further showed that early plantings produced 0.029 and 0.090% greater P and K, but 0.070% lesser Na over late planting seeds, respectively. The simple correlation coefficient (r) studies revealed that P content of early planting exhibited significant positive association with K (0.533), Na (0.653), soluble-sugars (0.615) and grain yield (0.448). While, in case of late plantings they only exhibited significant positive association with protein contents (0.548).
