A rapid screening (hydroponic) and field testing programme There is increasing interest in improving the nitrogen (N) use efficiency of cultivated crops, due to the high cost of synthetic N fertiliser. Since existing differences in N use efficiency between sugarcane varieties could be exploited to improve N fertilisation, a hydroponic pot experiment was conducted to test the performance of seve...

A comparative study on the effect of excess copper (Cu) supplied through leaves and root treatments in soybean plants is presented. Although Cu was accumulated in leaves upon both treatments, important differences were observed between Cu treatment of leaves and Cu supplementation in hydroponic medium. The application of 50 μM CuSO4 on leaves increased chlorophyll content, oxygen evolution acti...

Pumpkin ( cucurbita maxima ) belongs to cucurbitaceae which include pumpkin, gourds, melons and squashes. They are characterized by their seed oil. Pumpkin plant has been grown since the earliest history of mankind 1 . ( Brucher – 1989 ). Pumpkin are grown around the world for variety of agricultural purposes, the seeds show anti helmintic, taenicide diuretic, cardio tonic, anti-inflammatory, a...

Historical Perspective Muskmelons, often called cantaloupes in the United States, are not commonly grown here. True cantaloupes have deeply grooved fruit with a hard, warty, or scaly rind and orange or green flesh. Muskmelons (Cucumis melo L. Reticulatus Group), on the other hand, possess a fruit rind that is netted. The muskmelon is a member of the Cucurbitaceae (cucumber) family, which also i...

Although phosphorus is an essential factor for proper plant growth in natural environments, an excess of phosphate in water sources causes serious pollution. In this paper we describe transgenic plants which hyperaccumulate inorganic phosphate (Pi) and which may be used to reduce environmental water pollution by phytoremediation. AtPHR1, a transcription factor for a key regulator of the Pi star...

this research compares the performance of floating systems planted with vetiveria zizanioides as a hydroponic approach for removing nutrients from two contaminated waters. for this purpose, two pilots with overall net volume of 60 litres were constructed and inoculated by secondary treated domestic wastewater (stdw) and irrigation water obtained from minab reservoir (iwmr) in batch mode. regard...

Under USSR, a set th...

this research was conducted to determine the best temperature for storing different melon cultivars (ghasry, khaghany, tashkandy) and the best concentration and treatment length for immersion in an emulsion of sunflower oil and sodium bicarbonate. after harvest, precooling and sorting, the melons were treated with an emulsion of sunflower oil (3%, 5%) and sodium 2% sodium bicarbonate for 5 or 1...
