In order to make mechanized planting economically viable, the present spring planting period for Norway spruce (Picea abies (L.) Karst.) seedlings in Scandinavia needs to be extended. To evaluate the possibilities to extend the planting period, six field experiments were established in four years during which frozen-stored, dormant seedlings and actively growing seedlings targeted for spring pl...

Cultural practices can affect the quality of pineapple fruits and its variation. The objectives of this study were to investigate (a) effects of weight class and type of planting material on fruit quality, heterogeneity in quality and proportion and yield of fruits meeting European export standards, and (b) the improvement in quality, proportion and yield of fruits meeting export standards when...

Wheat (Triticum aestivum L.) was planted as winter crop using raised bed and conventional planting system with four N levels at Regional Wheat Research Station, Rajshahi (latitude 28°75′ N and longitude 92°58′ E), during November to March in 2002 and 2003 to study N content in grain and straw, uptake of total nitrogen, N use efficiency, fertilizer recovery percentage and grain yield. The highes...

Degraded forests are among of the most important environmental and commercial problems around world. Turkey has 22.74 million hectares forest area, out which 9.656 ha (42%) unproductive. To transform these unproductive into productive ones, restoration including rehabilitation is one best actions. In this sense, juniper species play an role for degraded lands because they drought-tolerant withs...

extended abstract 1. introduction in dry areas, crop yield is generally low and there are limitations in fulfilling goals such as increasing the area under cultivation and reducing the cost of production. in such circumstances, the agricultural activity is limited to crops that can tolerate the harsh climatic conditions, secure farmers' income, and tolerate saline and limited water resources in...

The basic requirements for small scale cropping machines are, they should be suitable for small farms, simple in design and technology and versatile for use in different farm operations. A manually operated template row planter was designed and developed to improve planting efficiency and reduce drudgery involved in manual planting method. Seed planting is also possible for different size of se...

In the 1990’s, the World Agroforestry Centre (ICRAF) initiated a domestication programme of indigenous fruit trees (IFTs) in Southern Africa to increase farmhousehold income through farmer-led tree planting and thus conserve bio-diversity. From the farmer's point of view planting domesticated IFTs is an investment under uncertainty and irreversibility. As timing of planting is flexible, real op...

The effects of alachlor (2.25 kg a.i./ha) and fenamiphos (2.25 kg a.i./ha) on the penetration and development of Heterodera glycines were examined on Glycine max cultivars Deltapine 105 planted 29 April, 29 May, and 29 June 1986 and Deltapine 105 and Centennial planted 15 May, 15 June, and 15 July 1987. Penetration was lowest on the third planting of soybeans and on fenamiphos-treated plants. D...

A panel of polymorphic microsatellite markers have been developed in coast redwood (Sequoia sempervirens). Two loci in particular (Seq18D7-3 and Seq21E5) demonstrate the potential of microsatellite genotyping in the assessment of genetic diversity and inheritance in redwoods. The highly polymorphic Seq18D7-3 marker provided evidence for the planting of non-local redwood seedlings in a restored ...
