Influence of nitrogen fertilization and defoliation frequency on nitrogen constituents and feeding value of annual ryegrass.
Two experiments were conducted to determine the seasonal effects of N fertilizer (NF) and defoliation interval (DI) on specific N fractions within annual ryegrass (AR) and overall usage of AR N by growing lambs. In Exp. 1, NF (0, 112, 224, and 336 kg of N/ha) and DI of 2, 4, or 6 wk were factorially applied to AR plots. Both decreasing DI and increasing NF increased N levels in AR in a manner t...
متن کاملUrinary nitrogen concentration from dairy heifers grazing kale supplemented with either plantain or perennial ryegrass baleage in winter
The effect of feeding two different supplements (perennial ryegrass or plantain baleage) on urinary nitrogen (N) excretion from dairy heifers (8 months old, 180 kg liveweight (LW)) grazing kale was examined in two successive winters. Heifers (n=90 and 80 in Years 1 and 2, respectively) were offered 2.5 kg DM kale/100 kg LW/day and approximately 3 kg DM/heifer/day of either perennial ryegrass or...
متن کاملThe Effect of Root-zone Nitrogen concentration on Corn
Nitrogen (N) is a major enzyme constituent making it a determining factor in plant yield and health. When a plant is deficient in N the shoot:root ratio typically decreases, chlorosis occurs, and growth is reduced. The objective of this study was to determine the level of nitrogen needed for optimal growth of corn. Plants were grown in containers and watered with 0, 0.3, 1.0, 3.0, and 10 mM N f...
متن کاملInterplanting Annual Ryegrass, Wheat, Oat, and Corn to Mitigate Iron Deficiency in Dry Beans
This study evaluated whether grass intercropping can be used to alleviate Fe deficiency chlorosis in dry beans (Phaseolus vulgaris L.) grown in high pH, calcareous soils with low organic matter. Field studies were conducted at the University of Wyoming Sustainable Agriculture Research and Extension Center in 2009 and 2010. Black- and navy beans were grown alone or intercropped with annual ryegr...
متن کاملEstimating Grain and Straw Nitrogen Concentration in Grain Crops Based on Aboveground Nitrogen Concentration and Harvest Index
Simulating grain (Ng) and straw (Ns) nitrogen (N) concentration is of paramount importance in cropping systems simulation models. In this paper we present a simple model to partition N between grain and straw at harvest for barley (Hordeum vulgare L.), wheat (Triticum aestivum L.), maize (Zea mays L.), and sorghum (Sorghum bicolor Moench). The principle of the model is to partition the abovegro...
