Abstract

A field experiment was conducted during the autumn seasons 2020 and spring 2021 in the fields of one of the farmers of the village of Al-Jilawia in the Alexandria sub-district (30 km north of Babylon) in order to study the effect of two factors, namely nitrogen, where the recommended quantity was divided into (two batches, three batches, four batches) and its symbol (N1, N2, N3)The second factor was spraying manganese with three concentrations (0, 20, 40) mg. L-1 and its symbol (Mn0, Mn1, Mn2). The experiment was conducted according to a randomized complete block design (RCB D) according to factorial order. The following results showed: The nitrogen level (N3) was significantly excelled on the rest of the levels for all the studied traits except for the oil percentage, where the level (N1) was excelled by giving it the highest average for the trait. As for the effect of manganese, it exceeded the level (Mn2) for all the studied traits by giving it the highest averages for the autumn and spring seasons. As for the biinteraction between nitrogen and manganese, the combination (N3XMn2) was superior by giving it the highest average for all the studied traits and for the autumn and spring seasons, except for the oil content of the grains, where the treatment (N1XMn2) was superior.
