Maize-wheat cropping sequence

An investigation was carried out at Sher-e-Kashmir University of Agriculture Science and Technology of Jammu during 2013-14 and 2014-15, to assess the influence of 4 tillage systems and 3 weed-control practices on weed dynamics and productivity in maize-wheat cropping sequence. In maize, grain yield of maize was statistically at par in continuous conventional tillage (CT-CT) in both maize and wheat and conventional tillage in maize and zero tillage in wheat (CT-ZT).

The present study was conducted to know the organic and inorganic fraction of nitrogen in soil under long term maize-wheat cropping sequence. It was observed that the effect of fertilizers and manures on ammonical nitrogen were reduces with depth irrespective of various treatment applied and with nitrate nitrogen, decreasing trend of this fraction with depth was observed. The pooled analysis of both year results reveals that the highest hydrolysable ammonia nitrogen (HAN) was found in treatment i.e. T9-100% NPK + FYM 10 t ha-1 .
