Agricultural production continues to be constrained by a number of biotic and abiotic factors that can reduce crop yield quantity and quality. Potassium (K) is an essential nutrient that affects most of the physiological processes that influence plant growth. To understand the effect of potassium, a pot culture experiment was carried out with graded levels of potassium to study the influence of potassium on physiological parameters of maize in black calcareous and non-calcareous soils. | Influence of graded levels on potassium on physiological parameters of hybrid maize in inceptisol
