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...
ett, 1999), planted early and at low populations; thus, relying on the sorghum hybrid to adapt to the growing Typical planting recommendations for dryland grain sorghum [Sorconditions by tillering. Research by Jones and Johnson ghum bicolor (L.) Moench] in the southern High Plains are to delay (1991, 1997) demonstrated that the optimum planting date, until soil water is adequate for crop establ...
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...
Abstract The earthquake that occurred on September 28, 2018 with an strength of 7.4 at a depth 10 Km, triggered tsunami along the coast Palu city.

Regenerating longleaf pine by artificial means is an essential component of restoring the ecosystem across most of its range because there are limited acres of longleaf stands remaining. Establishing longleaf pine is an early step in the ecosystem restoration process. An overview discussion of artificial regeneration techniques and related issues are presented this paper. Other papers follow in...
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...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
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...
