The effect of tillage and weed management practices on yield and nutrient uptake in wheat (Triticum aestivum L)

Abstract

A field experiment entitled “The effect of tillage and weed management practices on yield and nutrient uptake in wheat (Triticum aestivum L)” was carried out at Agronomy research form, N.D University of Agriculture and Technology Narendra Nagar, Kumarganj, Ayodhya (U.P.) during rabi season of 2017-18 to find out the effect of various tillage and weed management practices on growth, yield attribute, yield, nutrients, uptake, change in Physico- chemical properties of soil after harvesting the wheat crop and economic of various treatments. The combination of the five tillage systems (CT, ZT, CT, ZT+R, and ZT+R) and three weed management practices (Clodinafop + metsulfuron 60+4 g ha-1 + one hand weeding) was laid out in Split Plot Design and replicated thrice. The soil of the experiment field was silt loam in texture and medium in fertility status. The result revealed that among various tillage and weed management practices conventional tillage (CT) and Clodinafop + metsulfuron 60+4 g ha-1 + one hand weeding were found effective as compared to zero tillage system in increasing growth, yield attributes and yield of wheat during 2017-18. Adaptation of conventional tillage along with integrated weed management practices was also found most effective in increasing the uptake of nutrient. It can be concluded that under wet land condition for obtaining, better growth, yield attributes grain and straw yield, nutrients uptake, conventional tillage should be adopted / applied in wheat crop. However, for improving soil health, zero tillage + crop residue should be applied.
