Effects of Residue Decomposition on Productivity and Soil Fertility in Rice–Wheat Rotation
containing about 1.90 million Mg of nutrients, are available in the IGP of India (Sarkar et al., 1999). In the Rice (Oryza sativa L.)–wheat (Triticum aestivum L.) farmers in Indian Punjab alone, about 12 million Mg of rice straw India burn or remove residues to facilitate seedbed preparation. Incorare burned annually, which causes about 0.7 million Mg poration of residues before planting of the...
متن کاملResidual phosphorus and zinc influence wheat productivity under rice-wheat cropping system.
Continuous cropping of rice (Oryza sativa L.) and wheat (Triticum aestivum L.) deplete soil fertility and crop productivity. One strategy to increase crop productivity under rice-wheat system is balanced application of crop nutrients. Field experiment was conducted to assess the impact of phosphorus (0, 40, 80, 120 kg P ha(-1)) and zinc (0, 5, 10, 15 kg Zn ha(-1)) on the productivity of rice ge...
متن کاملExtractable Phosphorus as Affected by Humic Acid Application in Salt Affected Soils
To use of organic fertilizer sources for increasing crops production on sustainable basis has become imperative because the cost of chemical fertilizers is high. An experiment was conducted during 2006 on two saltaffected soils of District Charsadda to evaluate the effect of different levels of single super phosphate (SSP) alone and in combination with humic acid (HA) on phosphorus availability...
متن کاملGenotypic and environmental interaction in advanced lines of wheat under salt-affected soils environment of Punjab
Wheat cultivars of diverse origin including approved varieties of different provinces of Pakistan i.e. Punjab, NWFP and Sindh were tested against different salinity levels in laboratory as well as in naturally saline fields in different ecological zones. Initially, 16 genotypes were studied for germination test at 6 different salinity levels ranging from 0-25 dS/m (2, 5, 10, 15, 20, 25, EC= dS/...
متن کاملSoil Physical Characteristics and Crop Productivity as Affected by Tillage in Rice-Wheat System
Tillage practices significantly influences soil physical characteristics and crop productivity. The infiltration characteristics, bulk density, porosity, penetration resistance, grain yield of rice and wheat were measured under no-till without residue (NT), roto-tillage (RT), and no-till with residue i.e. happy seeder (HS) in rice-wheat cropping system in sandy loam (SL) and loamy sand (LS) soi...
