Three Stages

A study was conducted at two locations to evaluate the effects of cheat (Bromus secalinusL. ♯3BROSE) competition on four seeding rates (4.5, 9.0, 13.5, and 22 kg/ha) of alfalfa (Medicago sativaL. ‘Riley’). Three stages of first harvest (early bud, early bloom, and late bloom) were imposed on fall-planted alfalfa, with and without cheat overseeding, to determine the effects of harvest stage on alfalfa yield and quality. Cheat infestations significantly decreased alfalfa production and forage quality. Increasing the seeding rate of alfalfa only partially offset these losses. Harvesting early helped minimize the effect of cheat competition. First-harvest protein yield of forage was significantly decreased by, cheat overseeding. Total protein yield at first harvest was not affected by cutting stage but did increase with the two higher seeding rates of alfalfa.

The introduction of glyphosate-resistant (GR) alfalfa offers a new weed management system for alfalfa establishment; however, alfalfa seeding rates are based on conventional cultivars. Determining optimum seeding rates allows forage producers to maximize yield, quality, and profitability with GR alfalfa. Field experiments were established in 2005 and 2006 to determine the effect of seeding rate and weed control on GR alfalfa yield, forage quality, and persistence up to 3 yr after establishment. Seeding rates of 4.5, 9.0, and 18 kg ha−1were evaluated. Weed control methods during the seeding year included no herbicide, glyphosate applied once before the first harvest, and glyphosate applied once before the first harvest and then 7 to 10 d following subsequent harvests. Alfalfa yield was greater at higher seeding rates and when weeds were removed with glyphosate. Season forage yields were the greatest with the 18 kg ha−1seeding rate and where no herbicide was applied. Weed biomass often was lower at the higher seeding rates and was 91 to 98% lower in the glyphosate treatments compared to the nontreated. Forage quality was not affected by seeding rate but varied by herbicide treatment depending on establishment year. Plant density increased with seeding rate and treatment effects persisted for three growing seasons. Herbicide treatment did not affect stand density as greatly as seeding rate and did not influence stand longevity.

Abstract Brown midrib (BMR) forage sorghum (Sorghum bicolor (L.) Moench) silage is a reasonable alternative to corn (Zea mays L.) silage for areas with limited soil moisture. Traditional forage sorghum varieties are tall and prone to lodging, with low forage quality. Brachtyic dwarf BMR forage lines are shorter, lodging resistant and have higher forage quality. Newer, earlier hybrids have expanded the potential adaptation of forage sorghums to more northern areas. A two-year study was conducted during the 2014 and 2015 growing seasons using newly available brachytic dwarf BMR forage hybrids to determine the effects of different seeding rates and N (nitrogen) fertilization rates on forage dry matter (DM) yield and quality for two hybrids. The experimental design was split-split-plot with four replications. In each replication, main plots were two hybrids [AF7202 (early maturity) and AF7401 (late maturity)], subplots were two seeding rates (198,000 seeds ha-1 and 296,400 seeds ha-1), and sub-subplots were two N rates (123 kg ha-1 and 168 kg ha-1). Dry matter yield and forage-quality parameters were measured for each treatment. We observed significant differences between hybrids for all the parameters, except neutral detergent fiber digestibility (NDFD) in 2015. The early maturity hybrid, AF7202, had higher yields, higher starch content and net energy for lactation (NEL) levels than AF7401. The dwarf hybrid, AF7401, had higher crude protein (CP) content and NDFD than AF7202. AF7202 was more responsive to the higher N rate than AF7401. Crude protein was increased as N level increased for both hybrids. Other forage quality traits were unaffected by N rates. Neither variety responded to an increase in seeding rate. This study showed that the earlier brachytic dwarf forage sorghums, such as AF7202, managed with recommended seeding rates and possibly higher N rates, have good potential for high forage yield and quality in central Pennsylvania (PA).

The results of studies on the influence of agrotechnological techniques on the productivity of alfalfa (Medicago sativa), cultivation on agro-peat soils in the south of Belarus were presented. It was established that the yield of green mass on average over 4 years of life was 393.6–517.9 c / ha when sown under cover and 494.3–629.8 centners ha-1 with coverless sowing. Productivity — 56.5–75.1 and 69.5–89.7 centners ha-1, respectively. A positive correlation between the increase in the yield and productivity of the grass stand with an rise in the seeding rate and doses of fertilizers applied was noted.

Given that this is the inaugural edition, we thought that the first issue of the international journal «ArchAlp» needed to be characterized by a wide angle view, taking shape as sort of veritable tour d’horizon of the alpine space. Thinking with the scientific committee of the journal, it seemed to us that a reflection on the characteristics of contemporary architectural production in the European Alpine area, starting from regionally-based analyses and interpretations, could be very important. A description of the state of the art, which in order to have scientific validity must be based on comparative interpretations, has the aim of restoring continuity and differences in the “building culture” among the various Alpine regions. From here the idea of building the central core around a series of local monographs.

Analysis of the height and leafiness of plants of oats (fodder), pea (spring), field pea was carried out depending on the seeding rates and fertilization. It was established that under the increase in the seeding rate of oats by 25 %, the height of plants of the grass and legume components rose irrespectively of the rate of fertilization. The leafiness of leguminous crops was 2.9—3.1 times higher than that of oats.
