Spotted gum (Corymbia citriodora subspecies Variegata) has the potential to be the major hardwood species for large-scale plantations in South East Queensland, Australia, but production research is limited due to the lack of age of research plots. Optimal spacing is a major subject of concern. Based on time series data from a spotted gum experiment site, growth performance is analysed for five ...

Marigold cultivation is now a profitable enterprise to the farmers, but the socioeconomic data and information of this flower are very scarce in Bangladesh. Therefore, the study was conducted to identify agronomic practices, analyze relative profitability, and input-output relationship during February 2011. Primary data were collected from 100 randomly selected farmers from Jessore and Jhenaida...

Stem maintenance respiration rates were measured in five contrasting balsam fir (Abies balsamea (L.) Mill.) stands. At 15 degrees C, average respiration rates for individual stands ranged from 120 to 235 micro mol m(-3) s(-1) when expressed per unit of sapwood volume, from 0.80 to 1.80 micro mol m(-2) s(-1) when expressed per unit of stem surface area, and from 0.50 to 1.00 micro mol g(-1) s(-1...

The results of nine experiments to study factors influencing the efficacy of N(phosphonomethyl) glycine (as Roundup) in killing sugarcane are reported. These factors include varying rates, methods of application, disturbance of the cane after application, the presence of dew on the foliage during application and the susceptibility of sugarcane varieties. Other factors such as season, soil type ...

Corn silage represents a mixture of highly digestible, energy-dense grain and a poor quality forage (stover). The value of altering the grain to stover ratio through agronomic and harvesting strategies has been recognized for some time, however many of these practices have been applied to hybrids selected primarily for grain yield and adapted for harvest as silage. Although the feeding value of...
