Abstract: In order to examine the different stages and different heights of detopping effects on yield and nutrient uptake of maize (DHM-117), a field experiment was conducted at College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Hyderabad, India, in 2014-15. The experiment was laid out in a randomized block design comprising of a factorial combination of three stages of detopping and three heights of leaves detopping. The three stages are (D1-10 days after silking, D2 -20 days after silking and D3-30 days after silking) were tested with three heights of leaves viz., L1- detopping up to two leaves, L2- detopping up to four leaves, L3 -detopping up to six leaves with a control and replicated thrice. It was found that, more grain yield and nutrient uptake were recorded in control (no-detopping). Higher yield and nutrient uptake were observed with D3 and lowest in D1. Among different heights of detopping more yield and nutrient uptake were observed in L1 and lowest in L3. It was concluded that nutrient uptake was related to production of grain and stover yield. As the number of leaf loss causes reduction in grain and stover yield, hence lower nutrient uptake by plant.
