Information on above- and below-ground primary production for a wide range of agro-ecosystems is needed. The objective of this study was to quantify the shoot and root mass, shoot mass/root mass ratios, and root lengths of four barley (Hordeum vulgare L.) cultivars (Abee, Bonanza, Harrington and Samson) grown in a Black Chernozem in north-central Alberta. The cultivars were grown using a randomized complete block design with three replicates and were sampled at the tillering, stem-extension, heading, and ripening stages.

Abstract:
Water availability can limit maize (Zea mays L.) yields, and root traits may enhance drought adaptation if they can moderate temporal patterns of soil water extraction to favour grain filling. Root system efficiency (RSE), defined as transpiration per unit leaf area per unit of root mass, represents the functional mass allocation to roots to support water capture relative to the allocation to aerial mass that determines water demand. The aims of this study were to identify the presence of hybrid variation for RSE in maize, determine plant attributes that drive these differences and illustrate

The results of the effect of fertilizers on the root mass, chemical composition and amount of alfalfa nutrients Medicago, (Fabaceae). Along with this, when the root mass is decomposed, the soil is enriched with mobile phosphorus compounds. It was found that the application of mineral fertilizers in the ratio of N60P90K60 significantly increases the root mass. An increase in root mass, along with an increase in organic matter, has a positive effect on the amount of nutrients in the soil, improves water–physical properties and increases soil fertility. 125.7–235.8 kg/ha of nitrogen, 26.1-58.7 kg

Abstract:
The effect of bottom heat, wounding, and duration of stem basal IBA dip on macropropagation of Milicia excelsa was investigated. Bottom heat enhanced root dry mass and accelerated root initiation. Percentage rooting and root dry mass were not affected by wounding and duration of stem basal treatment. However, wounding interacted with bottom heat to affect dry mass (P < 0.05). Root biomass was 60% higher from wounded cuttings than from nonwounded cuttings under the nonheated condition. Chemical names used: 1H-indole-3-butyric acid (IBA).

We examine this relationship and the harms of carceral displacement, which fall heaviest on poor and low wealth communities in the US, especially majority Black communities. Despite being only 13 per cent of the US population, almost 50 per cent of those held in state prisons are Black. Guided by Fullilove's research on the harms of urban renewal, we inventory the damage incarceration exacts on health, wealth, and political power.

Crop roots transport water and nutrients to the plants, produce nutrients when they decompose in soil, and provide organic C to facilitate the process of C sequestration in the soil.

This study was conducted at Swift Current, Saskatchewan, in 2006 and 2007 to characterize the root growth and distribution profile in soil for selected oilseed and pulse crops.

One-year-old, root-bearing wax-apple trees were grown in different-sized containers filled with potting mixture to test if container volume restricts shoot and/or root growth and thereby lends itself to forcing culture. The trunk cross-sectional area (TCSA) at 15 cm above the soil was measured to assess vegetative growth. After 6 months, the TCSA had increased quadratically with container volume.

Citron watermelon (Citrullus lanatus var. citroides) is a drought-tolerant cucurbit crop widely grown in sub-Saharan Africa in arid and semi-arid environments. The species is a C3 xerophyte used for multiple purposes, including intercropping with maize, and has a deep taproot system. The deep taproot system plays a key role in the species’ adaptation to dry conditions. Understanding the root system development of this crop could be useful to identify traits for breeding water-use efficient and drought-tolerant varieties.

The allelopathic effect of coffee roasting residue on the germination and development of seedlings of corn, soybean and cowpea was evaluated. The physiological quality of seeds and seedlings was determined by means of the germination test, first germination count, germination speed index, mean germination time, shoot and root length, shoot and root dry mass and the ratio of shoot dry mass and root dry mass. The use of coffee residue inhibited germination and reduced the germination speed and dry mass accumulation of the seedlings of the three evaluated species.
