Randomized trial analyses the impact of sowing period and fertilization on naked oat yield, suggesting optimal conditions for growth.
Naked oat is a spring cereal crop with a good yield potential and high nutritional grain value owing to its high content of protein, fiber, fat and minerals. The trend of climate change by increasing temperatures and aridity has a negative influence upon plant growth and crop yield stability. Analyzing the evolution of climatic conditions for the Ilfov area (Southeastern Romania) in the past 10 years (2006-2015), we observed an increase in average temperature by 1.5⁰C and a decrease in the annual rain autumn amount by 45.4 mm. Research was conducted for the naked oats crop (GK Zalan variety) and the purpose was to analyze plant growth and yield potential by sowing the crop in autumn, as compared with the spring crops and the influence of mineral fertilization. All the analyzed parameters (panicles/sqm; number of panicle/plant; yield grain /panicle; thousand grains weight; hectolitre mass, grain yield) had maximum values for the autumn sowing period (October) and N₁₀₀P₅₀ fertilization level. Grain yield was 3,962 kg.ha⁻¹ exceeding the spring crop yield by 55% (2,550 kg.ha⁻¹).
