Species mixing boosts root yield in mangrove trees

Oecologia, 2012
Enhanced species richness can stimulate the productivity of plant communities; however, its effect on the belowground production of forests has scarcely been tested, despite the role of tree roots in carbon storage and ecosystem processes. Therefore, we tested for the effects of tree species richness on mangrove root biomass: thirty-two 6 m by 6 m ...

Breeding for root yield in alfalfa

Canadian Journal of Plant Science, 1991
Winter survival of alfalfa (Medicago sauva L.) has often been associated with the size of the root system but breeding for a larger root system has never received much attention. The objectives of this study were to detect variability for root traits among seven alfalfa entries grown under two nitrogen fertilizer treatments (R- and N-treatments) which

Root pruning and yield of maize

Netherlands Journal of Plant Pathology, 1965
The effect on yield of artificial injury to the root system of maize was assessed in two trials both on sandy soil at Wageningen. In the first in 1960 only severe injury (removal of half of the root system in the five-leaf stage or a third or more at the beginning and end of flowering) reduced the yield of straw significantly.

Association Between Sugarbeet Root Yield and Sugarbeet Root Maggot (Diptera: Otitidae) Damage

Journal of Economic Entomology, 1998
Sugarbeet root maggot, Tetanops myopaeformis von Roder, is a major insect pest of sugarbeet throughout much of North America. Root maggot damage is routinely rated on a 0 (no damage) to 5 (severe damage) scale. In 42 trials, the relationship between visual damage and root yield was examined. The mean damage rating in the absence of insecticides was 3.3±

Effect of abamectin on root‐knot nematodes and tomato yield

Pest Management Science, 2012
AbstractBACKGROUND: Tomato growers in Shandong Province, China, commonly face heavy root‐knot nematode infestations. Current methods of control include cadusafos and methyl bromide (MeBr), but alternative methods are required because of the high toxicity of these pesticides and the ecological risk of their use.

Root nodule bacteria to improve yield of wheat

Plant and Soil, 1985
Beneficial effects on yield and N-assimilation in wheat cv. HD2329 due to inoculation with nine strains belonging to six species and cowpea miscellany of genus rhizobium and Azotobacter were observed. Stimulation of soil Azotobacter and Azospirillum in the root region of wheat occurred due to seed inoculation with Rhizobium.

Effect of Pachymetra Root Rot on Sugarcane Yield

Plant Disease, 1994
The effect of Pachymetra root rot on yield of sugarcane was assessed through a correlation of soil inoculum density with yield in the susceptible cultivar Q90. Variation in plot inoculum density was created by growing cultivars of varied resistance in the previous crop.

Sowing Date Affects Development and Root Yield of Radish

International Journal of Vegetable Science, 2008
Abstract Radish (Raphanus sativus L.) cultivars are very specific in how they respond to temperature and photoperiod. The present investigation was carried out to evaluate eight cultivars of radish established at six sowing dates for characters affecting root yield.

Root growth, water potential, and yield of irrigated rice

Irrigation Science, 1997
Root length density (Lv), leaf water potential (Ψ leaf) and yield of rice were studied in 1983 and 1984 on a Phool bagh clay loam (Typic Haplaquoll) and on a Beni silty clay loam (Aquic Hapludoll) in the Tarai region of Uttar Pradesh under naturally fluctuating shallow (0.07–0.92 m) and medium-depth (0.13–1.26 m) water table conditions with six water ...

Bioassay to assess root rot in pea and effect of root rot on yield

Netherlands Journal of Plant Pathology, 1993
Infection of pea roots by soil-borne pathogens causes foot and root rot. In 1985 research was started to develop a method to predict the root rot likely to occur in prospective pea fields. In a bioassay the pea cultivar Finale was sown in a composite soil sample from each field in pots under standardized conditions in the greenhouse.
