The field experiment entitled “Effect of fly ash and phosphorus levels on growth and seed yield of raya (Brassica juncea L.) in south-west Punjab” was conducted during the rabi season 2018-2019 at Experimental Farm, Guru Kashi University, Talwandi Sabo, Bathinda (Punjab). The experiment was laid out in split plot design comprising of two levels of fly ash (0 and 10 t/ha) in main plot and four phosphorus levels (0, 15, 30 and 45 kg P2O5/ha) in sub plot. The results showed that application of 10 t/ha fly ash gave significantly maximum seed yield (2362 kg/ha) and increase was 6.8% over control. The application of phosphorus increased the seed yield of raya and the maximum seed yield (2489 kg/ha) was recorded with 45kg P2O5/ha application. These increase in seed yield was 29.1, 7.7 and 3.1% over control, 15 and 30kgP2O5/ha respectively. Similar trend was observed in case of stover yield. Application of fly ash resulted in significant increasing growth parameters i.e. number of branches per plant (13.2), leaf area index (4.26) and dry matter accumulation (87.1 q/ha) of raya. Similarly, yield attributes i.e. number of siliquae per plant (404.5), number of seeds per siliqua (12.3) and test weight (4.2 gm) was higher with fly ash application than control. Application of phosphorus at the rate of 45kg P2O5/ha significantly increased the plant height (191.7 cm) and dry matter accumulation (90.2 q/ha), number of siliquae per plant (417.2) and number of seeds per siliqua (12.5) as compared to other levels of phosphorus.
