Abstract—Rice straw pellets are a promising fuel as a renewable energy source. Financial analysis is needed to make a uti lization system using rise straw pellets financially feasible, considering all regional conditions including stakeholders related to the collection and storage, production, transportation and heat utilization. We conducted the financial analysis of feasibility for a heat uti...

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...

A Rice Sheller is used for obtaining polished white rice from paddy. There are about 3000 Rice Shellers in Punjab and 50000 in India. During the process of shelling lot of dust is emitted from different unit operations like paddy silo, paddy shaker, bucket elevators, huskers, paddy separator etc. These dust emissions have adverse effect on the health of the workers and the wear and tear of the ...

Mining natural variations is a major approach to identify new options to improve crop light use efficiency. So far, successes in identifying photosynthetic parameters positively related to crop biomass accumulation through this approach are scarce, possibly due to the earlier emphasis on properties related to leaf instead of canopy photosynthetic efficiency. This study aims to uncover rice (Ory...

in order to evaluate the effects of nitrogen levels and its split application on growth indices and their relationship with grain yield of rice (cv. khazar), a field experiment was conducted at rice research institute of iran with 11 treatments arranged in a randomized complete block design with 3 replications in 2008. nitrogen fertilizer levels (10, 20 and 30 kg.ha-1) were applied according to...

Water available for irrigation is declining in many rice-growing regions around the world. Global populations continue to rise increasing crop production demand. Rice production systems must face the dilemma of maintaining or increasing yields with less water available to irrigate. Alternate wetting and drying (AWD) has shown to be an effective tool for water conservation in irrigated rice syst...

Insufficient and high variability in rice yield is a threat to food security in China, prompting the need for strategies to mitigate yield variability and increase productivity. This study investigates the presence of production risk and technical inefficiency for a sample of rice farms in the Xiangyang city of China using a stochastic production frontier framework. Results from the risk functi...

The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
