use of available moisture and by avoiding heat stress. Fall planting is desirable because drier soil conditions Available winter hardy lentil (Lens culinaris Medik.) germplasm allow for planting the crop without the excessive soil has prompted interest in the development and use of cultivars that compaction that is common with spring planting in cold can be fall planted in cold highland areas. ...

Received for Publication July 27, 1984 INTRODUCTION The time and amount of nitrogen (N) uptake affects both root and extractable sucrose yield of sugarbeets (Beta Vulgaris L.). Either excessive or late N fertilizer applications and subsequent plant N uptake from applied•or residual N sources cause an increasing proportion of the photosynthate to be used for top growth at the expense of both roo...

proper sowing date along with providing normal growth rate in rape oilseed plants significantly leads to higher seed and oil yield via decreasing cold damages. the experiment was conducted as factorial with two factors including sowing dates with 4 levels (12 and 23 september, 2 and 12 october) and genotypes with 5 levels (modena, licord, okapi, opera and zarfam) in three replications. the stud...

Abstract Alternative strategies are needed for management of glyphosate-resistant (GR) horseweed in soybean. Integrating a cereal rye cover crop with soybean planted narrow rows may improve control and reduce herbicide selection pressure herbicide-resistant biotypes. Four site-years experiments were conducted Michigan to determine whether fall-planted terminated glyphosate 1 wk prior (early ter...

Optimizing the timing of nitrogen (N) enhanced efficiency fertilizers (EEFs) may maximize winter wheat ( Triticum aestivum L.) grain yield, protein content, and N-use (NUE). From 2013 to 2018, experiments were conducted at two irrigated six rain-fed sites across Canadian Prairies (24 site-years) evaluate responses N source timing/placement effects EEFs. Nitrogen sources included untreated urea,...

Agricultural accidents are a frequent cause of severe injury. Sixty-four patients with such injuries were seen from October 1981 through September 1984. The patients ranged in age from 2 to 73 years. The highest incidence of injury occurred during spring planting (May through June) and fall harvesting (September through October). The tractor and grain auger were the most common injuring agents....

In a young walnut orchard planted on black walnut rootstock, and stunted as a result of root lesion nematode feeding treatments are being applied in an effort to invigorate tree growth and/or significantly reduce the nematode population. Treatments began in 1989 and include: (1) Spring grafting two paradox seedlings to the existing trees trunk (llinarching")i(2) application of Nemacur 3 nematoc...

There is an increasing market for locally grown malting barley (Hordeum vulgare L.) in the Northeast US. Malting must meet certain quality standards acceptability brewing market. Up-to-date recommendations are needed regionally adaptation to ongoing climate change. A two-year field experiment was conducted assess interactive influence of three dates planting (5 September, 15 and 25 September), ...

The effects of irrigation and planting pattern on wheat in field conducted at Taian, northern China during 2011-12. The experiments consisted of two planting patterns (single and double rows) and two irrigation levels (0 and 180 mm) resulting in the same plant density (200 × 10 plant/ha). Each experiment plot was 3 m × 3 m in size and replicated thrice in split-plot design. During course of stu...
