The effect of radius of curvature and spading frequency on various dependent variables, i.e. weighted mean clod size, soil bulk density, cone index and cone index ratio were studied. The experiments were conducted in soil having 15.7 per cent clay, 53.6 per cent silt, and 30.7 per cent sand. During experimentation, moisture content of soil was maintained between 13 and 14 per cent. The radius of curvature used were C1 (Flat), C2 (15 cm) and C3 (30 cm). Four levels of bite lengths viz., 4, 6, 8 and 10 cm at travel speed of 18.47 cm/sec were selected for the study. These corresponded to four levels of spading frequencies namely F1 (1.85 cycles/s), F2 (2.31 cycles/s), F3 (3.08 cycles/s) and F4 (4.62 cycles/s). The spading frequency was determined by dividing the travel speed by the bite length. The dependent variables decreased with increase in radius of curvature and spading frequency. Weighted mean clod size, soil bulk density and soil cone index decreased with increase in spading frequency and radius of curvature. However, it increased with increase with blade width.Keywords

The most common form of biomass used as renewable energy and it is widely used. Recently more attention has been focused on identifying suitable biomass species, which can provide high-energy outputs, to replace conventional fossil fuel energy sources. The type of biomass required is largely determined by the energy conversion process and the form in which the energy is required. To provide energy the use of biomass has been mainly to the development of civilization. Recently pressures on the global environment have led to calls for an increased use of renewable energy sources. Biomass is one major potential source of renewable energy and the conversion of plant material into a suitable form of energy, usually electricity or as a fuel for an internal combustion engine, can be achieved using a number of different routes, each with specific pros and cons. A brief review of the main conversion processes is presented, with specific regard to the production of the fuel.Keywords

The present study assessed the energy requirement for the harvesting of paddy with combine harvesting with/without Super Straw Management System and wheat sowing with different farm machinery having straw retention and straw incorporated in the fields. The straw retention treatments i.e. T1and T2 whereas straw incorporation treatments i.e. T3 and T4 were taken in the study. The total energy consumption was maximum for treatment T4 (5529.92 MJ/ha), followed by treatment T3 (5487.47 MJ/ha), followed by treatment T2 (3485.15 MJ/ha) and treatment T1 (2539.40 MJ/ha). The least human energy consumption (22.01 MJ/ha), diesel energy (551.95 MJ/ha) and tractor and machinery energy (551.95 MJ/ha) was observed for treatment T1, while the maximum human energy, diesel energy, and tractor and machinery energy was observed in treatment T4 (52.17 MJ/ha), T3 (3442.63 and T4 (644.89 MJ/ha). The electrical energy (1401.78 MJ/ha) and submersible pump energy (13.68 MJ/ha) was observed in treatment T3 and T4, respectively. The residue retention practice of wheat sowing with Happy Seeder after paddy harvesting with combine harvester having Super Straw Management System is the efficient energy input to manage the paddy residue.Keywords
