The effect of salicylic spraying and planting distances on certain Physiological and Yield traits of Oats (Avena sativa L.)

A field experiment was conducted at the Research Station of the Field Crop Department College of Agriculture – Tikrit University, Saladin Governorate for the winter season 2022-2023 to study the effect of spraying at different levels of concentrations of salicylic acid and planting at various distances of Oat crops on some of the characteristics of Physiological and vegetative growth and yield. The experiment was carried out using a factorial random complete block design with three replicants in two factors, the first is spraying the salicylic growth regulator with three concentrations (0, 75, and 150) mg L-1. The second factor included distances between the planting rows (10 and 20 cm), the results showed an improvement in the level of concentration of salicylic 100 mg L-1 Compared with the rest of the salicylic concentration levels in the quality of duration of dry matter production (Biomass duration) and the absolute growth rate, the number of grains in panicle and the weight of a thousand oats grain trait, the distance (spacing) factor between the planting rows 20 cm improved compared with 10 cm planting spaces in all qualities studied in the experiment.  As for the Interaction between the two factors of the experiment, the concentration recorded 100 mg L -1  and the distance between the planting rows was 20 cm high significant differences from the rest concentration levels of the regulator (salicylic) and row planting distances
