Interactive Effect of Tillage and Organic Residues on Crop Growth under Wheat-Rice System in Semi Arid Pakistan.
The use of appropriate tillage practices and organic residues are essential for crop production on sustainable basis while improving soil health and protecting the environment. The effects of tillage and organic residues were investigated on cop yield (rice and wheat) and crop nutrient status. The crop growth parameters, tillers, biological yield, grain and straw yield and crop nutrient status were investigated. The tillage systems used were, deep tillage (DT), conventional tillage (CT) and minimum tillage (MT) while organic residue levels were control, 15 and 30 Mg ha–1. The growth and yield components of both crops were affected significantly by the application of treatments. The organic matter serves as panacea for soil and the soil physical properties also affected by the tillage systems and application of organic residues. The results indicated that number of tillers of wheat crop significantly improved (445 m–2) when organic residues were applied at 30 Mg ha–1. The maximum biological yield (12.1 Mg ha–1) and economic yield (4.83 Mg ha–1) were also recorded under 30 Mg ha–1 organic residue applications. For rice the maximum biological yield (19.1 Mg ha–1) and economic yield (6.21 Mg ha–1) was recorded under same level of organic residue. The crop parameters varied with respect to tillage systems. The information on soil parameters may be utilized in preparing the soil management work more effective for sustainable crop production with minimum damage to the soil and environment under semi arid conditions in Pakistan.
