A comparative study on drying of basil leaves CIGR Journal
Parmar, Mansukhlal Ramjibhai; Kumpavat, Mahendrasinh T.; Doshi, Jayesh Sevantilal; Kapdi, Shyamsundar S..
Basil is a popular aromatic and annual herb growing in many regions of the world.  Immediately after its harvesting, the highly perishable raw material, i.e. leaves, have to be preserved against deterioration and spoilage.  More often, during peak period, most of the crop is lost/wasted due to lack of proper post-harvest processing techniques.  Drying is by far the most widely used treatment, which needs to be performed very carefully and preciously so as to preserve the aroma and color of the leaves.  Various drying treatments and experimental methods viz., solar drying, tray drying, vacuum drying and fluidized bed drying were carried out at the temperatures of45°C,55°Cand65°Cto find and suggest the optimum drying condition for acquiring quality dried...

A new scheme for large-scale natural water storage in the floodplains: the Delhi Yamuna floodplains as a case study Eprints@IARI
Soni, Vikram; Gosain, A.K.; Datta, P.S.; Singh, Diwan.
The top layer of accumulated sand washed down by floods over millions of years, makes river floodplains into giant aquifers. We propose a scheme for the natural storage of excess monsoon river-water discharge in the extensive and deep sand top layer of the floodplain of the river. The excess monsoon discharge can be used for a regulated inundation of an embanked area of the floodplain – to soak in and store the water. This storage can then be used for the withdrawal of water during the dry months. We illustrate this by an evaluation of the potential of the Yamuna floodplains in the National Capital Territory of Delhi and show that there can be an annual yield of 600–900 MCM of water, which is three-fourths the total water supply to Delhi. This makes it an...

Bio-Drainage: An Alternate Drainage Technique to Control Waterlogging and Salinity Eprints@IARI
Dash, J P; Sarangi, A; Singh, A K; Dahiya, S.
Waterlogging and salinity are wide spread problems in irrigated as well as in nonirrigated areas. Often, subsurface drainage is needed in irrigation command areas to avoid waterlogging and soil salinization. Though the benefits of subsurface drainage are well documented, yet it is an expensive technology. Besides, it generates poor quality effluents, which would have to be either carefully reused or safely disposed. An alternative option claimed by some workers is bio-drainage, which is projected as the least expensive and more environmentally friendly method of land reclamation. Bio-drainage relies on vegetation, rather than mechanical means, to remove excess water through consumptive water use by the plants. Bio-drainage is economically attractive, as it...

Coefficients of repair and maintenance costs of self-propelled combine harvesters in Italy CIGR Journal
Calcante, Aldo; Fontanini, Luca; Mazzetto, Fabrizio.
Purchasing and maintaining agricultural machines are two of the most considerable costs of the agricultural sector, which includes farm equipment manufacturers, farm contractors and farms.  In this context, repair and maintenance costs (R&M costs) generally constitute 10%-15% of the total costs related to agricultural equipment and tend to increase with the age of the equipment; hence, an important consideration in farm management is the optimal time for equipment replacement.  R&M cost estimation models, calculated as a function of accumulated working hours, are usually developed by ASAE/ASABE for the agricultural situation in the United States, which is considerably different than agricultural context of other countries.  So, the goal of this...

Comparative evaluation of phosphorus losses from subsurface and naturally drained agricultural fields in the Pike River watershed of Quebec, Canada Eprints@IARI
Eastman, A; Gollamudi, A; Stampfli, N; Madramootoo, C A; Sarangi, A.
Phosphorus (P) is the limiting nutrient responsible for the development of algal blooms in freshwater bodies, adversely impacting the water quality of downstream lakes and rivers. Since agriculture is a major non-point source of P in southern Quebec, this study was carried out to investigate P transport under subsurface and naturally drained agricultural fields with two common soil types (clay loam and sandy loam). Monitoring stations were installed at four sites (A, B, C and D) in the Pike River watershed of southern Quebec. Sites A–B had subsurface drainage whereas sites C–D were naturally drained. In addition, sites A–C had clay loam soils whereas sites B–D had sandy loam soils. Analysis of data acquired over two hydrologic years (2004–2006)...

Current status and overview of farm mechanization in Pakistan – A review CIGR Journal
Rehman, Tanzeel ur; Usman Khan, Muhammad; Tayyab, Muhammad; Waqar Akram, Muhammad; Faheem, Muhammad.
Economic growth in Pakistani agricultural sector lags behind growth in industry and services, creating an ever widening rural-urban income fissure.  Agricultural mechanization plays a strategic role in improving agricultural production and productivity in developing countries. The average farm size in Pakistan is small (2.5 acres) and small and marginal land holdings (less than 2.0 ha) account for 85% of land holdings.  Mechanizing small and non-contiguous group of small farms is against ‘economies of scale’ for individual ownership of farm machinery. It was observed that there was a direct correlation between farm power availability and productivity during the past six decades. Being an agrarian country, mechanization can be called as back bone of...
