  • spring maize yield soil water use and water use efficiency under plastic film and Straw Mulches in the loess plateau
    Scientific Reports, 2016
    Co-Authors: Wen Lin, Wenzhao Liu, Qingwu Xue
    Abstract:

    To compare the soil water balance, yield and water use efficiency (WUE) of spring maize under different mulching types in the Loess Plateau, a 7-year field experiment was conducted in the Changwu region of the Loess Plateau. Three treatments were used in this experiment: Straw mulch (SM), plastic film mulch (PM) and conventional covering without mulch (CK). Results show that the soil water change of dryland spring maize was as deep as 300 cm depth and hence 300 cm is recommended as the minimum depth when measure the soil water in this region. Water use (ET) did not differ significantly among the treatments. However, grain yield was significantly higher in PM compared with CK. WUE was significantly higher in PM than in CK for most years of the experiment. Although ET tended to be higher in PM than in the other treatments (without significance), the evaporation of water in the fallow period also decreased. Thus, PM is sustainable with respect to soil water balance. The 7-year experiment and the supplemental experiment thus confirmed that Straw mulching at the seedling stage may lead to yield reduction and this effect can be mitigated by delaying the Straw application to three-leaf stage.

  • synthetic and organic mulching and nitrogen effect on winter wheat triticum aestivum l in a semi arid environment
    Agricultural Water Management, 2010
    Co-Authors: Debashis Chakraborty, Ritu Garg, R K Tomar, Ravender Singh, Sunita Sharma, Reeti Singh, S M Trivedi, R Mittal, P K Sharma, Kalpana Kamble
    Abstract:

    Field experiments were conducted in 2002-2003 and 2003-2004 to evaluate the relative performance of synthetic (black polyethylene) and organic (paddy husk and Straw) Mulches on soil and plant water status vis-a-vis N uptake in wheat in a semi-arid environment of India. Scope of better utilization of soil moisture was documented through all the Mulches, especially during initial crop growth stages, when the moisture content was 1-3% higher in Mulches. Soil temperature was more moderate under organic Mulches. Paddy husk recorded significantly higher plant biomass, while the effect of mulching in enhancing root growth was clearly documented. Organic Mulches produced more roots (25 and 40% higher root weight and root length densities compared to no-mulch) in sub-surface (>0.15m) layers, probably due to greater retention of soil moisture in deeper layers and relatively narrow range of soil temperature changes under these systems. Incremental N dose significantly improved all the plant parameters in both mulch and no-mulch treatments. Grain yield was 13-21% higher under mulch and so with increasing N levels. Nitrogen uptake was higher in organic Mulches and also with higher N doses, while polyethylene mulch showed mixed trend. Mulches were effective in reducing 3-11% crop water use and improved its efficiency by 25%. Grain yield and biomass were well-correlated with leaf area index (r=0.87 and 0.91, respectively) and water use was better correlated with root length than its weight. Results indicated substantial improvement in water and N use efficiency and crop growth in wheat under surface mulching, and the organic Mulches, especially rice husk performed better than synthetic Mulches.
