ABSTRACT- In this study, effect of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) on nutrient and toxic ions uptake by rapeseed was investigated in a two-year experiment. The experiment was conducted at Research Station, located in the College of Agriculture, Shiraz University, I.R. of Iran. Results indicated that an increase in water stress leve...

Seed germination, seedling emergence and crop establishment are important aspects of canola production, and are the main components of seed/seedling vigour. A major concern of seed businesses and canola growers alike is loss of seed vigour that may go undetected before planting. Two vigour assays, based on off-gassing of ethyl alcohol from poor vigour seed, are being developed. They are a simpl...

This paper demonstrates the potential of using Web search volumes for generating crop specific planting and harvesting dates in the USA integrating climatic, social and technological factors affecting crop calendars. Using Google Insights for Search, clear peaks in volume occur at times of planting and harvest at the national level, which were used to derive corn specific planting and harvestin...

Insecticides used at planting, either in-furrow or as seed treatments, are the recommended management option for control of thrips in cotton in Arkansas (Greene, 00 ). However, in recent years the efficacy of standards, such as aldicarb in-furrow, has decreased. This has resulted in added cost of control due to foliar insecticide applications being required in addition to the at-planting insect...

Historically preparing cottonseed for planting purposes involved the use of an acid delinting process, which allows the seed to flow in a single seed manner required for planting. This process is very effective and inexpensive, yet it could potentially be very hazardous to the seed, workers and the environment. This study evaluates the performance of a polymer starch coating applied to partiall...

Schizolobium parahyba var. amazonicum (Huber ex Ducke) occurs naturally in the Brazilian Amazon. Currently, it is being planted extensively because of its fast growth and excellent use in forestry. Consequently, there is great interest in new strategies to increase wood production. The interaction between soil microorganisms and plants, specifically in the roots, provides essential nutrients fo...

soil salinity is a serious problem in south khouzestan province. this study was conducted in shawoor agricultural research station, north of the city of ahwaz, on silty-clay soil with 8 dsm-1 salinity during 2006 and 2007. a completely randomized block design arranged in split plots with three replications was used. the plots (planting methods) were: broadcasting + disk harrow (p1), broadcastin...

Nitrogen fertilizer is commonly applied to winter wheat in the High Plains to achieve moderate to high yields. Typically, anhydrous N is applied in the summer or early fall with a tillage operation. Some growers apply liquid N in the spring if winter and spring moisture are high to take advantage of higher yielding condition. Phosphate fertilizer is less frequently used on winter wheat than N f...
