an experiment was conducted at zahak research station in zabol in 1996-97 to determine the best method of planting and plant density for mixed culture of cucumber and eggplant. in this experiment, yields of two crops were compared in individual and mixed cultures. in both systems the distances between two plant were 25 and 50 cm, and in the mixed culture eggplants were planted in the opposite o...
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...
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...
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...
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 ...
Ex-ante regulations and ex-post liability rules regulate the planting of GM crops in the European Union (EU). Those rules and regulations are in addition to the rules and regulations governing the planting of the equivalent non-GM crop. The legal basis imposing additional rules and regulations—the coexistence measures—is Directive 2001/18/EC on traceability and labelling of GMOs. The European C...
