Wheat: Preparing the Root System for Tillering and Vegetative Growth
The number of tillers is the primary yield component of straw cereals, including wheat, the world’s most widely grown cereal. The number of tillers is fundamental to crop yield development. It will compensate for the loss of plants during sowing due to poor planting. It is directly related to the final number of ears. Three leaves constitute a tiller, and this tiller can be transformed ...

A comparison of three isolines of cotton differing in fiber color for yield, quality, and photosynthesis
Naturally colored cotton (Gossypium hirsutum L.) fibers (CCFs) are eco-friendly for the textile industry because they omit the dyeing process and reduce harmful effluent liquor. However, the low yield and quality of CCFs have greatly affected their development. Limited information is available on the reasons for the low yield and quality of CCFs. The aim of this 2-yr investigation was to compare ...

Elevated atmospheric carbon dioxide and O3 differentially alter nitrogen acquisition in Peanut
Elevated atmospheric CO2 and ozone (O3) may affect productivity of legumes in part by altering symbiotic N2 fixation. To investigate this possibility, measurements of plant biomass, N levels and natural 15N abundance ({delta}15N) were used to examine the effects of elevated CO2 and O3 on N acquisition in field-grown peanut (Arachis hypogaea L.) using open-top chambers. Seasonal 12-h daily average ...

Hand Digging VS Tree Spade: which one gives the best results in terms of quality and time?
We were in Tuscany, with our guest and friend Mr. Leonida Cocchi, at one of his nurseries; we thank him for helping us dealing with this matter. All around the world tree spades are seen as tools to be used just for huge clods, especially by not experts. That’s because tree spades costs, while laborers has a short-term lesser cost. So, smaller clods it is thought to be wiser to produce them ...

Canopy nitrogen reserves: impact on soybean yield and seed quality traits in northern latitudes
Soybean [Glycine max (L.) Merr.] seed produced in the upper Midwest of the United States is lower in protein concentration than soybean produced throughout much of the Corn Belt, the southern United States, and Brazil. As protein comprises on average more than 400 g kg–1 of the soybean seed, yields in northern latitudes may be limited by seed protein accrual. Our objective was to examine the role ...
