Field experiments were conducted in Stoneville, MS, to determine the impact of soybean planting date and maturity group on stink bug (Heteroptera: Pentatomidae) populations. Maturity group IV and V soybeans were planted on three planting dates in 2003 and 2004. Planting dateswere lateMarchÐearlyApril, lateAprilÐearlyMay, and lateMayÐearly June. Plotswere sampled weekly with a standard 38.1-cm-d...

Early planting of bambara groundnuts (Vigna subterranea L. Verdc) in the southern Africa enables farmers to fetch premium prices before the markets are flooded with produce from the main summer growing period. However, adaptation of the crop outside the main growing season has not been studied in Zimbabwe. Therefore, this study evaluated 20 varieties at four planting dates covering contrasting ...

Neotephritisfinalis (Loew) (Diptera: Tephritidae), and sunflower bud moth, Suleima helianthana (Riley) (Lepidoptera: Tortricidae) are major head-infesting insect pests of cultivated sunflower (Helianthus annuus L.). Planting date was evaluated as a cultural pest management strategy for control of N. finalis and S. helianthana in several production regions of North Dakota during 2009 and 2010. R...

The hedonic price literature suggests that locations with more favourable characteristics should display compensating wage and house price differentials. Estimates of the marginal willingness to pay for small changes in climate variables are derived using the hedonic price technique applied to Italian data. A hedonic price model was specified in terms of January and July averages. There exists ...

Management plan model of agricultural planting information technology research and application of design system for agricultural production and digital has important theoretical and practical significance of agricultural planting. The study concluded, extracted the relevant agricultural planting design theory and technology research based on the show, applying the system analysis principle and ...

Low density plantings complemented by natural regeneration is an increasingly common reforestation technique to ensure growth of a sufficient number of trees from desired species while maintaining natural processes such as succession. One such form of low density planting that aims at lowering establishment costs—oak clusters—has been developed as an alternative to row planting since the 1980s ...

In a three year study, IOOderate and severe root pruning just before planting was compared to no root pruning, on two size classes of seedlings (smaller and larger than average). Seedlings were bar planted in holes the full depth of the planting bar blade. For the smaller seedlings, survival was 1.0 percentage point higher for moderate pruning and 5.6 points lower for severe pruning compared to...

In this issue of the Arboricultural Journal discussion approaches and methods for tree valuation continues with particular but by no means exclusive relevance to amenity trees in u...

A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield ...

Sclerotinia homoeocarpa (F. T. Bennett) is one of the most economically important pathogens on high-amenity cool-season turfgrasses, where it causes dollar spot. To understand the genetic mechanisms of fungicide resistance, which has become highly prevalent, the whole genomes of two isolates with varied resistance levels to fungicides were sequenced.
