EFFECT OF ORGANIC AND INORGANIC NITROGENOUS SOURCES ON YIELD AND YIELD COMPONENTS OF SUNFLOWER HYBRIDS Abuzar Iqbal and Inamullah Department of Agronomy, Faculty of Crop Production Sciences The University of Agriculture, Peshawar-Pakistan October, 2022 ABSTRACT Adopting proper nutrient management practices in conjunction with suitable cultivar might be a feasible technology to improve the yield and quality of sunflower besides maintaining the soil fertility. A field experiment entitled “Effect of organic and inorganic nitrogenous sources on yield and yield components of sunflower hybrids” was conducted at The university of Agriculture Peshawar during spring 2022. Experiment was laid out in randomized complete block design (RCBD) having three replications, each comprised of two factors i.e. sunflower hybrids (Hysun-33, Agura-4 and Parsun-3) and organic and inorganic nitrogenous fertilizers (farmyard manure, poultry manure and urea). Plots size 3m x 3.5m accommodating 5 rows each, 70cm apart with 25 cm plant to plant distance was used, with uniform seed rate of 8 kg ha-1 on ridges. Farmyard manure and poultry manure was applied 15 days before sowing. Recommended nitrogen (150 kg ha-1) was managed from organic and inorganic nitrogenous sources. All agronomic and management practices were kept uniformly for each experimental unit. Experimental results revealed that phonological, growth and yield parameters were significantly affected with the application of nitrogenous fertilizers and sunflower hybrids. Among the different nitrogenous fertilizers, combine application of PM + Urea delayed days to star formation (57.6) and flowering (76.1), similarly increased emergence m-2 (22), plants m-2 (6.3) and heads m-2 (6), also significantly improved leaf area index (3.73), plant height (170.2 cm), head diameter (19.83 cm), increased number of seeds head-1 (1104.2), seed weight head-1 (70.3 g), thousand seed weight (56.99 g), biological yield (12993 kg ha-1), seed yield (2783 kg ha-1), harvest index (21.43 %), oil content (47.43%) and oil yield (1268 kg ha-1) as compared to the rest nitrogenous treatments. Among the different sunflower hybrids, Agura-4 significantly delayed days to emergence (12.6), star formation (53.2) and flowering (71.9), similarly increased emergence m-2 (17.8), plants m-2 (5.3) and heads m-2 (5.1), also significantly improved leaf area index (3.50), head diameter (18.23), increased number of seeds head-1 (977.9), seed weight head-1 (65.8 g), thousand seed weight (51.49 g), biological yield (12610 kg ha-1), seed yield (2615 kg ha-1), oil content (344.73%) and oil yield (1144 kg ha-1) as compared to the Hysun-33 and Parsun-3. Exceptionally maximum plant height (172.1 cm) was recorded with Hysun-33. The current study recommended that sunflower hybrids Agura-4 along with the combine application of Poultry manure + Urea improved yield and quality in the study area.
