Prior to the 2000 planting season, some industry obsemers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers t...

Russian Wheat Aphid Barley Yellow Dwarf Wheat Streak Mosaic Planting winter wheat as early as possible, particularly under dryland conditions, can increase yields by 10 percent or more, but also increases the risk for several serious pest problems that can cause major yield losses. Early planting can create a situation called a green bridge where pests and disease move from maturing cereals or ...

The effect of seed size on germination and early growth of maize plant, was examined within three weeks to determine the best seed size require for planting. The larger size seed produced significant growth compared to medium size and small size. The seedling height, seedling width, and seedling biomass increased in larger size seed. The significant growth observed in larger size seed showed th...

The quality of planting material is one of the key factors that determine the success of tree farming and reforestation activities. In the Philippines, low quality seedlings are commonly used in smallholder plantings for reasons such as the limited supply of high quality seedlings and smallholders’ lack of awareness of the benefits of using high quality planting stock. The ACIAR-funded seedling...

Emission trading is considered to be an economically sensitive method for reducing the concentrations of greenhouse gases, particularly carbon dioxide, in the atmosphere. There has been debate about the viability of using urban tree plantings in these markets. The main concern is whether or not urban planting projects can be cost effective options for investors. We compared the cost efficiency ...

Researchers have proposed that planting false memories could have positive behavioral consequences. The idea of deceptively planting 'beneficial' false memories outside of the laboratory raises important ethical questions, but how might the general public appraise this moral dilemma? In two studies, participants from the USA and UK read about a fictional 'false-memory therapy' that led people t...

Stand establishment problems occur frequently in Arkansas rice fields and are commonly associated with cool soil temperatures (early planting) and saturated soils. There are several factors that affect rice stand establishment including diseases and insects. It is important to understand what pathogens or pests are the cause of stand problems in rice for managing stand establishment problems. I...

This is the second of two related reports dealing with the effects of cultivar × environment interactions on cabbage (Brassica oleracea L., Capitata Group) crop traits. This study examined planting date and cultivar effects on physical head traits of processing cabbage and compared these findings to those from a similar study of fresh market cabbage. Six cultivars of processing cabbage were pla...

to assess the radiation use efficiency (rue) of different rice cultivars under transplanting (tp) and direct-sowing (ds) systems and scrutiny of weed effect, a split-plot factorial experiment was conducted based on a randomized complete block design with three replications in 2011 at haraz extension and technology development center in mahmoudabad city, mazandaran. the main plots were two plant...

The soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae) is a significant soybean pest in the north central United States. Insecticidal seed treatments and host plant resistance are two commercially available management tools. Here we investigate the efficacy of both management tools throughout the season. Soybean lines containing the soybean aphid resistance genes Rag1, Rag2, or both...
