Effect of Nitrogen and Phosphorus on Seed Production of Three Onion (AIlium cepa L.) Cultivars

Muhammad Amjad, Muhammad Akbar Anjum and Habib Ullah Malik    

Abstract: N (0, 25, 50 or 75 kg ha–1) and P2O5 (0, 15, 30 or 46 kg ha–1) were applied in different combinations to onion cultivars Dark Red, Early Red and Faisal Red. All the P and half of the N were applied at the time of sowing while the rest of N was applied as a top dressing at flowering. Number of flowers per umbel significantly varied among the cultivars and was highest in Faisal Red (667), while the cultivars did not differ significantly in time taken to flowering, number of flower stalks per plant, diameter of umbel and seed yield. Fertilizer doses had significant effect on diameter of umbel, number of flowers pe umbel and seed yield, while time taken to flowering and number of flower stalks per plant have no significant response to these particular doses of fertilizer, Interaction between cultivars and fertilizers doses was only significant for number of flower stalks per plant. Maximum number of flower stalks were produced in cv. Faisal Red at a fertilizer dose of 75 kgN+45 kg P20, ha–1.
