Moving to a high seeding rate increased DM and TDN yields and decreased CP and P concentrations in forage corn.  Using a high nitrogen fertilizer rate increased yields of DM, TDN and CP, increased soluble protein concentration, and reduced P concentration.  However, when net returns...

Research shows that the highest plant densities and yields were produced at a narrow row spacing of 9 inches compared to those of 12, 18 and 24 inch spacings in a no-till production system. Increasing seeding rates of 2.8, 5.7 and 8.5 pounds per acre...

Under  irrigated and high-precipitation conditions, canola yield from 12 inch narrow-row precision planted canola was 10% higher than canola seeded with a 12 inch row air drill. However, under more water-limited conditions, yield from air drill seeded canola was equal or higher than the precision...

Ten lentil cultivars were found to be susceptible to Sclerotinia white mold and Botrytis grey mold. The highest yields were found on dryland plots at a seeding rate of 16 seeds/ft2. Irrigated plots yielded significantly less, and had significantly higher disease incidence. Sclerotinia white mold, caused...

For this study conducted in southern Alberta on irrigated and dryland plots, the precision planter with 12 inch spacing increased seedling emergence and plant stand density compared to an air drill on 12-inch spacing or precision planter with 20 inch spacing — as long as...

Seeding a tall cultivar at 80 seeds/ft2 in early May along with the application of an in-crop wild oat herbicide resulted in the greatest stand establishment and crop biomass, as well as the lowest weed biomass in flax. Flax is a poor competitor with weeds, and...

An optimum seeding rate between 30,000 and 35,000 seeds/ac for hybrid 63A21 sunflower, and between 40,000 and 45,000 seeds/ac for open-pollinated AC Sierra was determined under no-till cropping systems in Saskatchewan. At N fertilizer prices of around $0.50/lbs., the recommended N fertilizer rate based on...

This study compared three canola seeding rates (5, 10 and 15 seeds per square foot) with small and large seed
size lots from two different hybrids. 
It concluded that the most economic and least risky seeding rate to achieve adequate plant stand population is about 10...
