Limiting Factors of Agronomic Characteristics for Maize Through Nutrient Omission Techniques

Cob and seed characteristics of maize due to nutrient omission techniques

“…The inhibition of maize seed development due to the absence of nitrogen and manganese fertilizers will affect physiological processes, especially nutrient uptake and chlorophyll content in the production of biomass and seeds. This finding is supported by [12] that nitrogen uptake was lower, which inhibited leaf area and biomass of maize plants in the absence of N fertilizer compared to phosphorus and potassium. [14] explained that nitrogen plays an important role in seed formation through photosynthesis and the reduction of nitrogen nutrient negatively affects the photosynthetic performance of maize plants.…”

“…[11] found that the limiting factor for the vegetative growth of maize plants was the absence of nitrogen fertilization. [12] added that the highest percentage of limiting factors for maize plants sequentially found without fertilization, P+K; N+K; and N+P were 6.31-105.89; 7.73-87.01; 38.03-99.70; and 73.78-113.22% respectively, compared to N+P+K. Based on previous studies, the nutrient omission techniques have been implemented on the main macro-nutrients (N, P, K) at the vegetative growth of maize plants and it has never been reported on other macro-nutrients (Ca, Mg, S) and micro-nutrients until the reproductive stage.…”
