Energy use pattern for a selected village in the cotton-belt of Punjab

Energy use pattern analyses of greenhouse vegetable production

“…Diesel energy requirement was determined on the basis of fuel consumption and then, this value was converted into the energy units and expressed in MJ/1000 m 2 . The following equation was used in the calculation of fuel consumption [5,27] FC Z P m !R !SFC (2) where FC is the fuel consumption in l/h, P m is the tractor power in kW, R is the loading ratio in decimal and SFC is the specific fuel consumption and taken as 0.30 l/kW h. Power requirement and the loading ratio of the machines were measured by using a computer based data acquisition system. This system consisted of a dynamometer (50 kN), a torque meter (2000 N m), a data logger, a laptop PC and a connection frame.…”

Energy consumption and CO2 emissions analysis of potato production based on different farm size levels in Iran

“…Agriculture is one of the most important sectors, which consumes and supplies energy in the form of bio-energy (Ozkan et al, 2004a). The demand for energy in agriculture has increased considerably with the introduction of high yielding varieties, mechanized crop production practices, increasing populations, limited supply of arable land and desire for an increasing standard of living (Esengun et al, 2007b;Pannu et al, 1993). In all societies, these factors have encouraged an increase in energy use to maximize yields, minimize labor intensive practices or both.…”

Different Levels of Energy Use and Corresponding Output Energy in Paddy Cultivation in North Bank Plain Zone of Assam, India

“…Data such as energy input in the form of seed, fertilizer, irrigation, human, animal, farm machinery and output in the form of grain yield were collected. Operation-wise energy use for different field operations in terms of human, animal and machine (hr/ha) were calculated following the procedures suggested by Pannu et al, (1993). The physical data (inputs and outputs) were then converted to MJ/ha by multiplying the appropriate energy equivalent coefficients as reported by Mittal and Dhawan (1998).…”
