Abstract


Water stress is considered to be one of the most adverse abiotic stress factors influencing plant growth and their physiological and biochemical aspects. Field experiments were carried out to achieve the optimal use of soil application of poultry manure (0, 2, 4 and 6 ton/fed) in combination with foliar application of Mono Ammonium Phosphate (MAP) (0, 1, 2 and 3%) and its effects on productivity and quality of sesame grown under water stress condition. Soil application of 6-ton poultry manure per feddan combined with 3% MAP foliar spray gave the highest values of plant height (150.9, 123.1 cm), Capsule’s number /plant (86.6, 65.6), capsules weight (67.5, 51.7 g) and 1000 seed weight (5.94, 4.40 g) under sufficient irrigation and water stress condition, respectively. Foliar application of 3% MAP foliar spray gave the highest seed yield under both irrigation treatments as compared to control treatment. Application of 6 ton/fed poultry manure gave the highest increased percentage of seed yield (20.25%) under sufficient irrigation, and (16.24%) under deficit irrigation, and control treatment gave the lowest one. Results recommended that soil application of 6 ton/fed poultry manure combined with 3% of MAP foliar spray is important to minimize the harmful effects of drought stress on sesame seed yield under water stress conditions. The maximum net returns were registered in the treatment receiving 6 ton/fed Poultry manure under deficit irrigation. This practice can help to obtain higher profit over the conventional application of recommended dose of fertilizers to the crop.
