| dc.description.abstract | The aim of the study was to analyse the effect of fertilizers on Rice crop characteristics and its impact on grain yield. The data were collected from Norman E. Borlaug Crop Research Centre, G.B.P.U.A&T. Pantnagar, Rice Agronomy block. The experiment was laid out in Randomise Block Design with four replications and readings were taken timely as on the critical stages of the crop. The results of the study revealed that all crop characteristics were positively correlated with grain yield. Also multiple regression equation was obtained by the help of multiple regression models for predicting grain yield. Effectiveness of fertilizer treatments were tested by ANOVA and ANCOVA, it was found that different fertilizer combinations are significant with grain yield with p=0.000. Thus, the results obtained through ANOVA and ANCOVA are similar. Then ANOVA and ANCOVA were carried out for all five crop characteristics viz. Height, Test Weight, Shoot Number, Panicles number and Spikelet number. It was found that the treatments (different fertilizer combinations) are significant for all five characters with p=0.000. DMRT was also applied to compare the treatments pair-wise. Path coefficient analysis was performed to find direct and indirect effects of crop characteristics on grain yield. Results revealed that Test weight, Panicle number and Number of spikelets had direct positive effect on grain yield while Height and Shoot number had negative direct effect on grain yield. | en_US |
