in order to study the canopy temperature effect on protein and soluble sugar, oil percentage and yield of soybean in different planting dates, an experiment was conducted as factorial based on randomized complete block design with three replications in karaj and moghan areas during 2012-13. the studied treatments were included cultivar (‘williams’ and ‘l17’) and planting date (5th of may, 5th o...

Abstract In the Mid-Atlantic United States, there is increasing interest in delaying cereal rye termination until after soybean planting (i.e., green). Improved understanding of seeding rate effects needed to balance weed and agronomic management goals. We investigated rates on control crop performance when green complementary experiments two regions. The Pennsylvania experiment was replicated ...

Row-crop agriculture is a major source of nitrous oxide (N2O) globally, and results from recent field experiments suggest that significant decreases in N2O emissions may be possible by decreasing nitrogen (N) fertilizer inputs without affecting economic return from grain yield. We tested this hypothesis on five commercially farmed fields in Michigan, USA planted with corn in 2007 and 2008. Six ...

BACKGROUND Burn injury leads to resistance to the effects of non-depolarizing muscle relaxants. We tested the hypothesis that a larger bolus dose is as effective as priming for rapid onset of paralysis after burns. METHODS Ninety adults, aged 18-59 yr with 40 (2)% [mean (SE)] burn and 30 (2) days after injury, received rocuronium as a priming dose followed by bolus (0.06+0.94 mg kg(-1)), or s...

Canola sensitivity to delayed sowing date should be managed in such a way that the observance of crop rotation with less reduced in seed yield. The research was conducted to evaluate the yield variation of Hyola401 hybrid, affected by sowing date and nitrogen fertilizer treatments. In this study, the effect of planting date and different levels of nitrogen fertilizers on effective characteristi...

Delserone, L. M., and Cole, H., Jr. 1987. Effects of planting date on development of net blotch epidemics in winter barley in Pennsylvania. Plant Disease 71: 438-441. The influence of planting date on fall and spring net blotch epidemics (caused by Pyrenophora teres) was evaluated with the winter barley cultivar Pennrad. Experiments were conducted in Centre County, Pennsylvania, in 1982 and 198...

this study was aimed at evaluating the effects of planting’s different dates on the trend of leaf area index, dry biomass weight and panicle weight in addition to the yield of rice varieties for one year in the north region of khuzestan, as spilt plots in the form of fully random blocks in three repetitions. main factor was the date of planting at three levels (26 may, 10 jun, 26 jun) and the s...

ABSTRACT- Maize production, which is ranked after wheat and barely in Fars province, Iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. Therefore, proper planting method can improve irrigation water management. The objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...
