A research project was conducted to evaluate the impact of alternative citrus nitrogen and water management practices on groundwater nitrate concentrations beneath the vulnerable sandy soils in the ridge citrus region of Central Florida. Fifteen months of baseline data indicated that groundwater nitrate-nitrogen concentrations were above the Environmental Protection Agency’s Maximum Contaminant...

In this study, water and nutrient uptake from the substrate and responses of the crop to fertigation strategies were analysed. In an experiment and simulation study, the amount and frequency of fertigation and electrical conductivity (EC) of the fertigation water were changed for a tomato crop grown on rockwool. In a climate chamber, tomato plants were grown on rockwool while five different EC ...

Nowadays, many vegetables are grown inside greenhouses in which environment is controlled and nutrition can be supplied through water supply using electrical pump, namely fertigation. Dosage of nutrition in water for many vegetable plants are also known so that by controlling water supply all the needs for the plants to grow are available. Furthermore, water supply can be controlled using elect...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

A study was undertaken to know the combined effects of fertigation and consortium of bio-fertilizers on photosynthetic rate, chlorophyll content, yield attributing characters and yield of banana cv Robusta (AAA) at Indian Institute of Horticultural Research, Bangalore in the year 2010. From the results, it was observed that the treatment of 100% recommended dose of fertilizers through fertigati...

up to now, interactions between method and amount of nitrogen fertilizers application on plant density and variety of wheat under sprinkler irrigation systems have not been studied. thus, this research was conducted during two years in esfehan region with split factorial design. the treatments of this experiment were: three fertilizers application methods (conventional manual application at the...

A trickle irrigation experiment on sugarcane was established in October 1985 on the SASA Experiment Station farm at Shakaskraal. The objectives were to establish suitable operating procedures, to measure cane yield potential, and to study the effects of factors such as fertigation and crop row spacingon yieldsoftrickle irrigated sugarcane. The results ofthe plant and first ratoon crops of this ...

Optimal operation of greenhouse crops requires an appropriate management of fertigation, especially when the availability and/or the quality of irrigation water are limited and/or there are environmental constraints, such as those derived from Nitrate Directive in Europe. The paper illustrates the main features of a decision support system (DSS) for the fertigation management in soilless cultur...
