Description
Summary:The use of moving average values reduced the seasonal/irregular fluctuations in the data effectively and gave better fit as compared to that of original set of data. For wheat crop, various degrees of polynomials with different bases (X0.5, 1/X0.5 and X) explained the trend in yield due to various treatments. Majority of the fitted curves showed initial moderate increase, followed by a downward trend in the productivity till a later stage. The initial expected productivity ranged from 1525 (control) to 2544 kg/ha (NsPsKs). The productivity at last point of time ranged from 406 (control) to 2908 kg/ha (NsPsKs). In the medium black soil of Junagadh, under intensive cropping system, NsPsKs treatment was found better as compared to rest of the treatments in wheat crop.
