Foliar application of macro and micronutrients and productivity of oilseed crops: A review

Abstract

Macro and Micronutrients in oilseeds essential for plant growth, but plants require macro nutrients in large quantity and micronutrients relatively in smaller quantity. Macronutrients include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S). They play major role in protein and starch synthesis, fruit formation, nodulation, pegging, oil synthesis and chlorophyll production. Micronutrients include iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo) and boron (B). They play major role in translocation of photosynthesis, increases seed setting percentage, essential for translocation of sugar, germination of pollen grains, stigma receptivity, amino acid and protein synthesis which ultimately increase the productivity of oilseed crops.
