Influence of Tillage and Weed Management Practices on Yield and Nutrient Uptake of Maize

Abstract

A field experiment entitled ‘Influence of tillage and weed management practices on yield and nutrient uptake of maize’ was conducted during Rabi-2018 at all India coordinated research project on Weed Management, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad to study the effect of different tillage and weed management practices on nutrient uptake of maize. The soil of the experimental field was sandy clay loam in texture with moderately alkaline pH, low in available nitrogen, medium in available P and high in available K. The field experiment was laid out in split plot design with (five tillage practices) in main plots and (three weed management practices) in sub plots. The results revealed that highest total nitrogen uptake was recorded with conventional tillage (Transplanted rice) – zero tillage (maize) and it is on par with conventional tillage (transplanted rice) – conventional tillage (maize) treatments. The highest total phosphorus and total potassium uptake was recorded with conventional tillage (transplanted) – conventional tillage (maize) and it was on par with conventional tillage (Transplanted) – zero tillage (maize). Integrated weed management was found to be significantly superior with nutrient uptake followed by chemical weed management.
