To save water, get suitable establishment, shorten growth duration and increase grain yield of maize, this experiment was conducted as split plot factorial arrangement in randomized complete block design with three replications at Mahidshat research station (Kermanshah, Iran) in 2017 and 2018 growing season. Two planting dates (10th and 20th of July) were assigned to main plots, and a combi...
Salinity and water stress reduces the ability of plant to take up water and decrease growth rate, photosynthesis rate (An) and stomatal conductance (gs) of plants. In this study, effects of deficit irrigation with different salinity levels and planting method (in-furrow and on-ridge) as strategies for coping with water and salinity stress on physiologic properties of rapeseed was investigat...
a field study was conducted to determine the effects of planting method, density and nicosulforon on corn (ksc704) and weeds grown in corn at agricultural and natural resources research center of khorasan-razavi province, iran in 2009-2010 growing season. the treatments were: three planting methods (one row, two row and in-row), two planting density (75000 and 90000 plants/ha) and three doses o...
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 ...
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 ...
