Core Ideas Tillering was better in conventional than no‐tillage in plant cane but it was opposite in second ratoon. Minimum or no‐tillage produced higher sugarcane ratoon yields than conventional tillage in Florida Histosols. Overall, in a 3‐yr crop cycle, the yields were similar in all three tillage levels. Tillage effect on yield did not vary wit...

Sugarcane production of the Everglades Agricultural Area (EAA) occurs mainly in organic soils (Histosols). Even though drainage of these natural wetland soils allowed crop production, it also modified the dynamics of the soil microbiota. Consequently, the soil presents increased microbiological oxidation, what results in soil subsidence. Thus, soil...

Sugarcane (Saccharum spp. hybrids) monoculture was amended with leguminous rotation breaks (cowpea, Vigna unguiculata; and soybean, Glycine max) and compared with growers’ practice (sweet corn, Zea mays var. saccharata rotation; and bare fallow). After incorporation of rotation-break residues, fungicidal treatments (mancozeb, mefenoxam and azoxystr...

Sugarcane (Saccharum spp. hybrid) successive planting (also called monoculture) causes serious yield losses and its management is not well studied in Histosols. Based on very few studies in other sugarcane regions, root colonization by harmful soil fungi is considered as a major cause of this yield decline, but there is lack of knowledge on its man...

The usefulness of breeding to improve sugarcane (Saccharum sp. hybrids) crop performance and productivity depends heavily on the continued availability of new and beneficial genes and on novel approaches to the reproductive and agronomic controls used to access their full potential. One such novel approach is perhaps in the study of full or partial...

Key message The mean and variance of developmental rates of bamboos at different temperatures follow a power law. The rate isomorphy hypothesis, demonstrated in insects and mites, does not hold in bamboos. Abstract The developmental time of plants and poikilotherms can be significantly affected by temperature. Developmental rate (i.e. the reciproc...

Agricultural intensification has brought obvious increases in the extent and intensity of agricultural activities, which simultaneously led to rapid changes in landscape patterns. However, the relationship between agricultural intensification and pest damage was poorly known at the landscape scale, especially in China. We conducted an analysis to e...

In recent years, global changes are the major causes of frequent, widespread outbreaks of pests in mosaic landscapes, which have received substantial attention worldwide. We collected data on global changes (landscape and climate) and economic damage caused by six main insect pests during 1951–2010 in China. Landscape changes had significant effect...

The relationship between spatial density and size of plants is an important topic in plant ecology. The self-thinning rule suggests a −3/2 power between average biomass and density or a −1/2 power between stand yield and density. However, the self-thinning rule based on total leaf area per plant and density of plants has been neglected presumably b...

Transgenic crops are increasingly promoted for their practical effects on suppressing certain insect pests, but all transgenic crops are not equally successful. The insect pests can easily develop resistance against single Bacillus thuringiensis (Bt) toxin transgenic crops. Therefore, transgenic crops including two or more mixed Bt-toxins can solve...

Energycane has been proposed as a potential, perennial bioenergy crop for lignocellulosic-derived fuel production in the United States. Herbicides currently used in sugarcane and other crops can potentially be used in energycane if there is acceptable tolerance. Also, to limit future invasion of energycane escapes, herbicides used for perennial gra...

Commercial wheat farms were studied in Yinchuan Plain of Northwest China to assess the effects of two agro-farming systems on ground-dwelling predators. Pitfall trap methods were employed to investigate ground-dwelling predators during a four-year study from 2009 to 2012. Results showed that 9 species of ground-dwelling predators (Calosma maderae,...

Mosaic’s most distinctive symptom is a pattern of contrasting shades of green, often islands of normal green on a background of paler green or yellowish chlorotic areas on the leaf blade. It had not been a problem in Florida until 1996, when it was observed on CP72-2086, a major commercial cultivar, near the intersection of Hatton Highway and US 98...
