Effect of different rates of nitrogenous (mineral and bio) and potassium fertilization on sesame crop (sesamum indicum l.) in newly reclaimed sandy soils [electronic resource].

Two field e'xperiments were conducted at the Experimental Farm. Faculty of Agriculture. Suez Canal University at Ismailia during 2003 and 2004 seasons to study the effect of four treatments of mineral and bio nitrogen fertilization namely 30, 50, 70 and 50 kg N/fad plus biofenilizer (Syrialin) and three rates of potassium fertilizer 25, 45 and 65 kg K20/fad on yield. its components and yield quality of sesame Shandawyl 3 variety in sandy soils of Ismailia Governorate. Increasing mineral nitrogen fertilizer level from 30 to 70 kg N/fad significantly increased plant height. fruiting zone length, number of branches, capsules and seeds/plant, seeds/capsule. weight of capsules and seeds/plant, shelling percentage, IOOO-seed weight and seed and oil yields/fad, while seed oil content (%) was decreased . Applying biofertilizer (Syrialin) + 50 kg N/fad produced the highest values of the mentioned characters except seed oil content (%) and it deviated in this respect significantly with the rates 30 and 50 Kg N/fad but insignificantly with 70 Kg N/fad. Fertilizing sesame plants with 65 kg K20/fad produced significant increases compared to 25 kg K20/fad in all studied trailS except number of seeds/capsule.
