Abstract
Experiments to determine the effect of different NP combinations on the growth, seed yield and oil content of three mustard genotypes were conducted at the Latif experimental farm, Sind Agriculture University, Tandojarn on non-saline and non-sodic medium textured soil. The NP levels comprised 0-0,50-15, 75-30, 100-45, 125-60 and 150-75 kg NP ha', while the genotypes were early Raya, P-53/48-2 and 8-9. The results revealed that NP fertilizer increased significantly all the agronomic traits.of ths three genotypes. However, the difference between 150-75 and 125-60 kg NP levels was non-significant for all the traits including seed oil content. Among the genotypes, S-9 gave significantly higher seed yield but seed oil content was the highest in early Raya. Key words: mustard genotypes, NP combinations
