In: Zagazig Journal of Agricultural Research 2006.v.33(4)Summary: The present work was conducted to study the effect of fertigation and chemigation on green bean (phaseolus vulgris) under drip irrigation in sandy soil. The drip irrigation system was carried under three levels of total available water (75, 100 and 125 %), three nitrogen rates (40, 55 and 70 kg N/fed) and two methods of weed control (hand hoeing and herbicide Amex rates of 1.5 and 2 liter/fed) to investigate moisture distribution, emitter clogging, total weeds fresh weight, green beans production, water use efficiency, fertilizer use efficiency, cost production unit and net profit. The results showed that best soil moisture distribution was obtained around the emitter under level of available water of 100%.
