Long-term effect of crop residues incorporation on yield and soil physical properties under rice - wheat cropping system in calcareous soil

Abstract: The crop residue and Zn addition impacts on above ground biomass yield, Zn uptake and physical properties, viz. mean weight diameter (MWD) of water stable aggregates, bulk density (BD) and water holding capacity (WHC) were measured under a rice-wheat system in the 17th and 18th crop cycles...

The MWD, BD and WHC of post-harvest soil measured after harvest of the wheat crop varied from 2.80-3.88 mm, 1.27-1.42 Mgm-3 and 33.32-47.53%, respectively. The treatment with 100% CR and 10 kg Zn/ha had the highest level of MWD and WHC, whereas it resulted into the lowest BD. Increasing levels of Zn also influenced the MWD of water stable aggregates, BD and WHC positively. The correlations of WHC and MWD of water stable aggregates with different plant parameters were positive and highly significant, thus, indicating their synergistic relationship, i.e. higher the WHC and MWD of water stable aggregates higher the crop yield and Zn utilization by crops.info:eu-repo/semantics/openAccessChilean Society of Soil Science / Sociedad Chilena de la Ciencia del SueloJournal of soil science and plant nutrition v.18 n.1 20182018-03-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-95162018000100027en10.4067/S0718-95162018005000103
