Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at El-Bustan Sandy soil irrigated by drip irrigation, during 2003 and 2004 seasons. The experiments aimed to study the effect of three irrigation treatments with three different kinds of fertilizers and its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content in dry her...

Long-term use of drip irrigation technology may lead to root degradation and affect shoot growth and yield. A field experiment was conducted to investigate aboveand belowground growth responses to drip irrigation under mulch film (DI) in comparison to flood irrigation under mulch film (FI) in cotton. The monolith method was used to harvest roots at seven timepoints in the growth periods, and th...

This study investigated the comparative effects of reduced irrigation regimes--partial root-zone drying (PRD) and conventional deficit irrigation (DI)--on the incidence of blossom-end rot (BER) in tomato (Solanum lycopersicum L.) under three Ca-fertilization rates: 0, 100, and 200mg Ca kg(-1) soil (denoted Ca0, Ca1, and Ca2, respectively). The plants were grown in split-root pots in a climate-c...

A field experiment was carried out to study the changes of soil bacteria, fungi and actinomycetes in saline-sodic soils for different numbers of cultivated years under drip irrigation. The drip irrigation had substantial effects on levels of bacteria, fungi and actinomycetes. With increased number of cultivated years under drip irrigation, the soil biological properties were greatly improved. A...

In the Mesilla Valley of southern New Mexico, furrow irrigation is the primary source of water for growing onions. As the demand for water increases, there will be increasing competition for this limited resource. Water management will become an essential practice used by farmers. Irrigation ef®ciency (IE) is an important factor into improving water management but so is economic return. Therefo...
