A review: Effect of planting dates and added nitrogen fertilizers levels on growth and sesame yield

Abstract

Effect of planting dates (PD) and nitrogen fertilizers (NF) on growth of sesame plant, were tested at two PD of 1July and 15 July, and three NF levels 70 ,100and 130 kg.ha-1. The experiments were conducted in a factorial experiment under complete randomized design with three replications. The results showed that the PD of 15 July was significantly better than the PD of 1 July cm in all studied conditions. The RL, PL, PVI, 1000-WG and GY, 24.79 cm , 153.73 cm, 64.05 cm, 7.45g, and 0.91 t.ha-1, the treatment NF of 130 kg.ha-1 was significantly superior to the levels of 70 and 100 kg.ha-1 in all studied conditions. With the exception of the physical soil properties represented by the density and porosity of the soil, best results were achieved with a planting dates of 15 July and a nitrogen level of 70 kg.ha-1.
