<![CDATA[Effective fertilizer application can enhance rice growth and yield. The objectives of this study were to test the effect of NPK and Urea fertilizers doses on the growth and yield of rice lines from Ciherang x B11143D cross. The treatments were arranged by factorial (10x4) in split plot design and repeated three times. The main plot was ten rice lines and the sub plot was 4 levels of fertilizer, consisting of A1, A2, A3, and A4. The treatment effects were tested using analysis of variance. If the F-test is significant at a significance level of 0.05, the Duncan Multiple Range Test was performed to define the best treatment at the 5% level. The results showed that rice lines significantly influenced all variables except filled grain weight. P1 and P2 lines had the highest plant height and total tillers, and P5 had the highest total grain weight. The fertilizer doses and rice lines had an interaction effect for flag leaf length, total productive tillers, and unfilled grain weight. P1 and P2 lines had the highest flag leaf under A2 and A4 fertilizer doses, respectively. P1 had the highest total productive tillers and the lowest unfilled grain weight under A4. This study showed that A4 is the best fertilizer dose for the growth and yield of progeny lines of Ciherang x B11143D cross in Karawang regency. P1, P2, and P5 are the best lines and have the potential for further evaluation in the next field test.]]>
