Residue management through combination of machinery in combine harvested rice field

Abstract

Rice (Oryza sativa L.) is the most important crop of India and it occupies 23.30 per cent of gross cropped area of the country. Straw management and crop rotation alternative to burning straw by using machinery, straw height reduction helps in decomposition of straw. Straw management practice performed in the field of Faculty of Agricultural Engineering, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G) by using the different combination of machinery i.e. disc harrow, disc plough and rotavator (T1), stubble shaver, disc plough and rotavator (T2) to incorporate the straw into soil. The machine parameters were theoretical field capacity, actual field capacity, field efficiency, fuel consumption, energy requirement. The soil properties were moisture content, bulk density, cone Index, pulverization Index, mixing Index and physical properties of straw were moisture content, straw height, weight, straw population considered during field operation. Experiment was conducted by taken two treatments with their five replications comprised of different combinations of independent parameters on experimental field.
