Effects of zinc fertilizer rate and application method on photosynthetic characteristics and grain yield of summer maize
Zinc deficiency is a worldwide nutritional constraint for crop production in many types of soil, particularly in cereals growing in calcareous soil. Two field trials were conducted to study the effects of zinc fertilizer doses and application method on photosynthetic characteristics and grain yield...
