Yosef and Sagiv, 1982; Stark et al., 1983; Burt et al., 1995). However, very few studies have shown a benefit Subsurface-drip irrigation and fertigation with fluid N fertilizer of frequent or continuous fertigation compared with sources offers substantial flexibility for N fertilizer management. Fertiless frequent fertigation. Bar-Yosef and Sagiv (1982) gation events can be scheduled as often a...

Field experiment was conducted for 2 seasons to study the influence of drip fertigation in combination with or without bio fertilizers on yield, plant uptake and soil fertility of Bt cotton. The treatments comprised of four levels of drip fertigation viz., 75, 100, 125 and 150 per cent of recommended dose of fertilizers (RDF, NPK) combined with and without bio fertilizers, drip irrigation w...

A 2-year study was done to compare the effects of nitrogen (N) fertigation and granular fertilizer application on growth and availability of soil N during establishment of highbush blueberry (Vaccinium corymbosum L. "Bluecrop"). Treatments included four methods of N application (weekly fertigation, split fertigation, and two non-fertigated controls) and four levels of N fertilizer (0, 50, 100, ...

Nutrient uptake by trees is determined by root interception, soil availability, and tree demand. Fruit trees have low rooting density, especially in the case of dwarfing rootstocks. Mobility in the soil is a key factor in determining nutrient availability, and good management of nutrients requires that supply is matched to demand, in terms of amount, timing and retention in the root-zone, and t...

Sandy fields have been reclaimed to exploit the grain production potential in northwestChina. A 2-year statistically replicated field study was conducted to determine the effects ofmulched drip irrigation on soil water, soil nitrate, shoot root growth and yields of maize on asandy field in the Hetao irrigation district. Treatments included border irrigation (BI), fullymulched drip irrigation (F...

The rapid proliferation of fertigation in modern agriculture has brought about a growing demand for factory mixed fertilizer solutions, as well as wide-scale dissolution of solid fertilizers by farmers in the field. Rules of chemistry and physics control the rate of dissolution and, hence, the nutrient content in the fertilizer solution. Potassium chloride (KCl) is the cheapest potassium-contai...

Israel is a small country with a total land area of 21,000 km, from which 20% is arable land. More than half of Israel has an arid to semi-arid climate. Approximately half of the cultivated area (200,000 hectares) has to be irrigated due to lack of rainfall and other water resources. Approximately 80% of the irrigated land in Israel uses the fertigation method, combining the application of wate...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

Most species of Cucurbitaceae respond favorably to irrigation, especially when combined with fertilizers. The effect drip irrigation nitrogen fertigation in melon grown on a very light soil Central Poland, during 2013–2015, was evaluated. field experimental design split-plot four replications. Two factors were studied: (1) treatments applied two combinations—drip + broadcast fertilization (cont...
