Spectral Reflectance of Wheat Residue during Decomposition and Remotely Sensed Estimates of Residue Cover
Remotely sensed estimates of crop residue cover (fR) are required to assess the extent of conservation tillage over large areas; the impact of decay processes on estimates of residue cover is unknown. Changes in wheat straw composition and spectral reflectance were measured during the decay process and their impact on estimates of fR were assessed. Proportions of cellulose and hemicellulose dec...
متن کاملThe effect of PGPR and alfalfa extract on macronutrient and micronutrient contents of sorghum (Sorghum vulgare)
ABSTRACT- The increasing population and the pastures inability to meet food needs in livestock have led to the increase of cultivates forage plants. In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and alfalfa (Medicago sativa) extract on the growth and concentration of macronutrient and micronutrient contents of forage sorghum (Sorghum vulgare), an experiment was...
متن کاملEffects of relay-intercropping sorghum with winter wheat, alfalfa, and cotton on lady beetle (Coleoptera: Coccinellidae) abundance and species composition.
Creating conditions that enhance the abundance of resident populations of natural enemies in agroecosystems is considered critical to the efficiency of biological control of insect pests. We conducted a study to determine the potential of relay-intercropping for enhancing the abundance of aphidophagous lady beetles in sorghum. A relay-intercropping system consisting of alfalfa, winter wheat, an...
متن کاملDecomposition Dynamics and Changes in Chemical Composition of Wheat Straw Residue under Anaerobic and Aerobic Conditions
Soil aeration is a crucial factor that regulates crop residue decomposition, and the chemical composition of decomposing crop residues may change the forms and availability of soil nutrients, such as N and P. However, to date, differences in the chemical composition of crop straw residues after incorporation into soil and during its decomposition under anaerobic vs. aerobic conditions have not ...
متن کاملEffects 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...
