Evaluating the Impact of Different Tillage Regimes and Nitrogen Levels on Yield and Yield Components of Maize ( Zea mays L.)

Abstract

A field study to evaluate the impact of different tillage regimes and nitrogen levels on yield and yield components of maize (Zea mays L.), was conducted during autumn 2014 at Students Farm, Department of Agronomy, University of Agriculture, Faisalabad. The experiment was laid out in RCBD (Randomized Complete Block Design), with split plot arrangement having three replications. The experiment was comprised of three tillage regimes (Minimum, Conventional and Deep) and three nitrogen levels viz: 100, 200 and 300 kg∙ha−1. Urea was used as a source of nitrogen, sulphate of potash as a source of potassium and triple super phosphate as a source of phosphorous. The amount of phosphorous and potash was constant in all the treatments i.e. 125 kg∙ha−1 and 100 kg∙ha−1 respectively. Results of present study are summarized as yield parameters are significantly affected by different nitrogen levels and tillage regimes.
