Abstract:

An experiment was conducted during rabi season of 2016-2017 at Agricultural College and Research Institute, Killikulam to study nutrient removal pattern of weeds due to integrated weed management practices in hybrid maize. Weeds compete with crops for nutrients and nutrient removal by weeds is a serious problem in a widely spaced crop like maize. Adoption of various weed control treatments exhibited significant influence on N removal by weeds on 20 DAS. Application alachlor @ 1.5 kg a.i ha-1 as pre- emergence with one hand weeding on 30 DAS (T2) registered significant lowest N removal of 5.8 kg ha-1 by weeds. The next best treatment was mechanical weeding with power weeder twice on 15 and 30 DAS (T11) which recorded a removal of 6.9 kg ha-1 N by weeds. Unweeded control (T12) recorded highest N removal by weeds (13.2 kg ha-1) which was statistically on par with the treatments T3 and T1. Pre-emergence application of alachlor @ 1.5 kg a.i ha-1 with one hand weeding on 30 DAS (T2) reduced the weed population, weed dry matter production and nutrient removal (N, P and K) by weeds.
