Western Corn Rootworm Quick Facts… Western corn rootworm larvae feed on root hairs and small roots; larger rootworms feed on primary roots. Crop rotation is the most consistent and economical means of controlling western corn rootworm populations. Cultural practices that promote strong root systems and a vigorous crop will make corn more tolerant to rootworm […]
Corn: More Active Genes in Roots Mean Higher Yields Hybrid plants provide much higher yield than their homozygous parents. Plant breeders have known this for more than 100 years and used this effect called heterosis for richer harvests. Until now, science has puzzled over the molecular processes underlying this phenomenon. Researchers at the University of […]
Rice Cultivates Green Batteries from Plant Purpurin, left, extracted from madder root, center, is chemically lithiated, right, for use as an organic cathode in batteries. The material was developed as a less expensive, easier-to-recycle alternative to cobalt oxide cathodes now used in lithium-ion batteries. Here’s a reason to be glad about madder: The climbing plant […]
Quantifying Corn Rootworm Damage Every year farmers spend a lot of money trying to control corn rootworm larvae, which are a significant threat to maize production in the United States and, more recently, in Europe. University of Illinois researchers have been working on validating a model for estimating damage functions. Nicholas Tinsley, a doctoral candidate […]
Fertile Soil Doesn’t Fall from the Sky Remains of dead bacteria have far greater meaning for soils than previously assumed. The electron micrograph shows bacteria (Hyphomicrobium sp.; Yellow) growing up partly on solid surfaces, floors and sediment grains. During growth whatsoever cells die and deformed or fragmenting cell envelopes remain. Small-scale fragments of these shells […]
Rice Uses Light to Remotely Trigger Biochemical Reactions Chemical processes can be activated by light without the need for bulk heating of a material through a process developed by researchers at Rice University. The technique involves coating nanorods with thermophilic enzymes that are activated at high temperatures. Lighting the plasmonic gold nanorod causes highly localized […]
Rowing Kakri (Armenian Cucumber) It is a no-demanding type of plant, very disease resistant and pest resistant.. needs least fertilizer for growth and good yield.. Its is generally ready for harvest after 70 days…. The fruits can grow from 2-3 feet long and 2 inches in diameter, but are best eaten when between 12-15 inches […]
Eggplant Profile Overview Eggplant is a widely grown specialty vegetable in the United States. According to the 2007 Census of Agriculture (2009), eggplant was harvested on over 2,900 farms in 2007, an increase of over 690 farms since 2002. However, acreage declined to 6,038 acres during those five years. An estimated 159.8 million pounds of eggplants […]

Beet Production Douglas C. Sanders Extension Horticultural Specialist Department of Horticultural Science College of Agriculture & Life Sciences North Carolina State University Beets have been cultivated for centuries. Though grown mostly for the roots, beet greens are also popular in many areas. Beets are a common item in vegetable gardens, but few are produced in […]
Growing Beets in the Home Garden Climatic Requirements Beets prefer a cooler climate although they are tolerant of heat. Temperatures of 60 to 65 F and bright sunny days are ideal for beet plant growth and development. They can withstand cold weather short of severe freezing, making them a good long-season crop. Soils Beets prefer […]
