Increased costs of annual establishment of small grain pasture associated with fuel, machinery, and labor are eroding the profitability of stocker cattle enterprises. Interest has therefore increased in development of cool-season perennial grasses that are persistent and high quality. This study occurred on 24 ha (divided into thirty 0.81-ha paddocks) located at the University of Arkansas Divis...

Heifer performance, diet composition, and forage composition were compared during rotational and continuous grazing of mixed pasture (alfalfa, tall fescue, orchardgrass). One hundred eighteen yearling heifers were used to compare the three grazing systems during 2 yr. Treatments included continuous (CONT), 6-paddock rotational (6-PADD), and 11-paddock rotational grazing (11-PADD). Rotational pa...

To what extent can the private sector be relied upon for the protection of biological diversity? Bioprospecting, the search for valuable products such as pharmaceuticals in biological organisms, is one incentive mechanism that has received much recent attention in the literature (Polasky et al. 1993, Polasky and Solow 1995, Simpson et al. 1996, Koo and Wright 1999, Rausser and Small 2000). Simp...

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...

During 2007–2013, the Swedish Board of Agriculture granted support within a national program to about 1000 wetlands, corresponding to a 5300-hectare wetland area, with the dual goal to remove nutrients from water and to improve biodiversity in agricultural landscapes. The aim of the present study was to compare the effects on nutrient transports that are realized within the national program to ...

A survey of cable logging contracts was conducted in 5 of the 8 Alpine countries, namely: France, Germany, Italy, Slovenia and Switzerland. The goals of the survey were to set a gen­ eral reference for cable logging rates, to identify eventual differences between countries and to determine the effect of technical work parameters (i.e. piece size, removal per hectare, line length) on actual cont...

All the life stages of the reduviid predator Rhynocoris marginatus (Fab.) were released (30, 50 and 70 Days After Seedling Sowing -DAS) into the groundnut field at 5000/hectare. Spodoptera litura (Fab.), Helicoverpa armigera (Hubner), Atractomorpha crenulata, Chrotogonous trachypterus, Aphis craccivora, Mylabris pustulata and Mylabris indica were observed during the study period. R.marginatus s...

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 ...

watershed scale irnpact. Our objective was to estimate the watershed scale impact of grass buEers by comparing sediment and agichemical losses from two adjacent 14 1 165 hectare watersheds, one with conservation buffers and one without. Rainfall derived m o f f events frorn 2002-2003 were monitored for water runoff, TSS, phosphorous and atrazine loss. A conservation-watershed included 0.8 Ism o...

Selective logging has been applied in the Indonesian tropical rain forest since the 1960. This has resulted thousands of hectare logged-over forest. In Labanan, Berau, East Kalimantan, selective logging will enter the second rotation in 2010. A comprehensive analysis on the logged over forest condition should be made before harvesting the logged over forest. One aspect that should be considered...
