Response of various Canola genotypes to different fertility Levels under irrigated conditions of Dera Ismail Khan, KP Pakistan

An experiment was conducted to check the influence of various fertilizer combinations on canola varieties at Agronomic research area of Gomal University, Dera Ismail Khan, Pakistan. Randomized complete block design with split plot arrangement, having three replications was used for study. PARC canola (hybrid) and Faisal canola (open pollinated) cultivars were kept in in main plots, whereas various fertilizers NPK (120:60:60 kg ha-1). Rustamorgano (125 kg ha-1), Bio care (125 kg ha-1), H R care (125 kg ha-1), Ferti source (125 kg ha-1), NPK + Rustamorgano, NPK + Bio care, NPK + R care, NPK + Ferti source, control (no fertilizer used) ) were assigned to sub-plots. The yield and yield components of canola were significantly affected by using different fertilizers and varieties. The maximum siliqua length (12.00 cm), number of capsule per plant (439.00), 1000 grain weight (5.26 g), and grain yield (3547 kg ha-1) was recorded in PARC hybrid canola along with NPK applied @ 120:60:60 kg ha-1 .However, use of Ferti source +half NPK along with PARC hybrid canola was the second best yielding (2876 kg ha-1). As far as the net return is concerned, highest amount (Rs.120439/-) was earned in NPK @ 120:60:60 kg ha-1 with PARC Canola hybrid with benefit cost ratio.
