A web-based custom hiring model was developed to help farmers and custom-hiring service providers take decisions regarding owning/custom hiring of combine harvester for rice-wheat cropping system. It also gives the break-even acreage for owning a combine harvester along with various cost economics. The model was evaluated for two situations: situation I with own area of 100 acres and custom-hiring catchment area of 160 acres combined under rice and wheat, and situation II with own area and custom-hiring catchment area being 60 and 276 acres respectively. For situation I the model guided the user to opt for custom-hiring, while for situation II it gave a decision to own a combine harvester.Keywords

The world energy crisis has now given importance to solar energy utilization, research and development programmes all over the world. The sun is the largest fusion reactor known to mankind which supplies about 1000 times more energy than we need each day in the form of electromagnetic radiations. In order to harness solar energy, a dark surface is exposed to solar radiation so that it is absorbed1. Two main approaches currently in use to harness solar energy are converting it to electricity by photovoltaic approach and converting it to thermal energy by solar thermal conversion. The simplest and most efficient way to utilize solar energy is to convert it into thermal energy for heating applications. The economic feasibility of solar energy utilization depends upon its efficient collection, conservation and storage. The efficient utilization of solar energy for heating, cooling and process applications requires the use of flat-plate or even focusing collector systems which first receive, as much as possible, the incoming solar radiation and then deliver a large fraction of the thermal energy to the working fluid2. The flat-plate collector is the key component of any solar energy system.Full Text
