A program was initiated in 1998 to develop technology to improve water and land productivity in Kutch, a vast semi-arid and hot region in north-west India. Greenhouse cultivation was identified as basic approach. A new experimental facility was designed consisting of a greenhouse coupled to ETHE...

We present in this paper, an operational study of CJ Patel Wholesale Fruit and Vegetable Market (CJP Market) of Ahmedabad city. The market is viewed as a dynamic queuing system. A simulation model is constructed. Simulations are used to generate statistics on congestion as the volume of trade is...

This write up contains design computations for selection of structural members for a greenhouse to be installed at Bhujodi. Straight wall gable roof form was selected. Wind load estimates made for wind angle 0 degree and 90 degree on air tight structure. Analysis was also carried out for left...

Long sequences of daily rainfall are often needed for simulation. These (when available) are cumbersome to input. Also in many cases historical data are to short to include all possible patterns. Hence the need for synthetic data. Discovering the stochastic structure underlying daily rains is...

Tomatoes are produced and consumed year round. Wood carton is the dominant mode of packaging for produce coming to APMC Market, Ahmedabad from out-of-state. It has been known for long however that wood carton suffers from many shortcomings. It is unable to protect the produce sufficiently...

Tomato growers of Gujarat , north-west India , traditionally send produce to wholesale market in Ahmedabad city for auction. Growing areas lie about 250-300 km from the city. Growers were constrained to sell there even if the prices were not attractive which the case usually as season advanced...

A specially designed air-cooling (and heating) system using Earth Tube Heat Exchanger (ETHE) was installed in the dwelling of a 15-year old white tiger (Panthera tigris) named Mahesh at Kamala Nehru Zoological Garden, Ahmedabad (India) in October 2000. This was done to alleviate the stresses...

Physical dimensions, mass, shape and bulk density of vegetables grown around Ahmedabad have been determined. Measurements were carried out on samples at the farm immediately after harvest. Pattern underlying one of the characteristic dimensions has been identified. Statistical distribution that...

Tomatoes transported from long distances were procured from Sardar Patel Market, Ahmedabad. Fruits were inspected visually for mechanical damage. Experiments were conducted to study the effect of storage on weight loss, firmness and toughness. Injuries and losses due to mechanical causes were...

A large part of Gujarat in the North-west region of India is semi-arid. The lands are less suited for agriculture. Animal husbandry is therefore common. Productivity of cattle is however also low due to problems of feed and due to climatic stresses, specially heat. Environmental control of farm...
