Modification and Performance Evaluation of Fertilizer Band Placement Drill Machine for Wheat Crop in Rain-Fed Areas

Evaluation of rain-fed wheat (Triticum aestivum L.) genotypes for drought tolerance

Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...

Field evaluation of a grain drill equipped with jointers for direct planting in previous wheat crop residues

ABSTRACT-In conventional agriculture, a large amount of energy is consumed in fuel consumption and depreciation of farm tractors and any other farm equipment mostly in tillage and planting operations. The main purpose of this research was to evaluate a till-planting unit equipped with three jointers. This unit was expected to act as conventional furrow openers such as shovel openers tilling the...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

evaluation of increasing water productivity scenarios for rain-fed wheat by management analysis of cropsyst crop model in karkheh basin

water productivity is a function of crop yield and management operation. determination of different yield levels through field experiments is difficult. therefore, applying simulation model is an approach which makes possible to assess water balance, simulate growth process and survey different scenarios. using the cropsyst crop growth model to analyze water productivity, as an indicator of wat...
