Effect of various herbicides on the nutrient status of leaves and fruit quality of sweet orange cv. Blood Red

Effect of various herbicides viz. diuron, simazine, atrazine, weedone, dalapon and dalapon in combination with gramoxone was studied on the mineral composition of leaves and fruit quality of sweet orange cv. Blood Red. The nutrient status of leaves was profoundly influenced by various herbicides while no significant effect was observed on the physico-chemical characteristics of the fruits. Nitrogen, phosphorus and potassium content increased in all the herbicidal treatments. Zinc content in the leaves increased though it remained in deficient range, whereas iron content decreased. No consistent trend was observed in the manganese content of the leaves.
