Keeping the view in mind that environmental monitoring and crop management are of vital importance and that hese are essential parts of modern agricultural experimentation,the present symposium volume has been compiled.The subject matter of the volume has been presented in four parts,viz.(1) Abiotic environment and crops,(2) biotic environment and crops,(3) edaphic environment and crops and (4) modification of biotic environment and crops and quality,representing the four sessions for presentation of the papers.At length discussions were held on three driving variables of environment namely precipitation,relative humidity and temperature of the area and their impacts on crop production,herbagebiomass, carbon,nitrogen,fertilizers,animal numbers etc.
