Vast sums of public money are invested into universities globally as anchor institutions and knowledge bases providing seedbed resources for research development entrepreneurship. Focusing on university science technology we examine two U.K. case studies government support from the “Innovation Knowledge Centre” (IKC) program to translate industry innovation good. Although IKCs not tasked addres...
Ryegrass is the probably the most damaging weed to winter wheat over a large part of the high rainfall area in the central, north and east Texas. Economic losses in wheat occur through reduced grain yield, quality, foreign matter, and harvest efficiency. Yield loss can exceed 90% in heavy infestations. In addition to yield reduction, reduced harvest efficiency results in lower test weight, high...
In agrotechnical practice, it was found that between qualitative indices, which express the sowing precision achieved by planters determined in laboratory, and those under operating conditions, there are certain differences, sometimes quite significant. The decrease value of quality indices manifested increase number mistakes, either double planting holes (with at least two seeds), or missing h...
Seedbed conditions during corn (Zea mays L.) planting can have substantial impact on stand establishment and final yield. Planting management decisions are complex due to spatial variability caused by changing soil characteristics such as texture or landscape position. Field experiments conducted in central Missouri from 2017 2019 assessed the effects of varying depths Sites included fine- coar...
There is a difference of 45% to 55% between the attainable yield and potential rice. This gap may be due insufficient inputs poor mechanization status. In this regard, agricultural utmost importance obtain satisfactory yield. study was conducted determine level, power per unit area, probit regression, challenges faced by farmers understand status in rice cultivation. For this, 98 households Pyu...
Abstract The title of my article bears a double meaning. On the one hand, it refers to group Conservative politicians around Boris Johnson who studied at Oxford University in eighties and are identified Jonathan Coe’s novel as engineers behind Brexit; on other portrays fictional scholars more or less frustrated dissatisfied with university for various reasons turn their backs academia find luck...
Logging disturbance is important in uneven-aged stands because harvests are frequent, merchantable trees are retained, and regeneration may be present. Logging disturbance was monitored during the establishment of a study testing the application of uneven-aged silvicufture in an irregularly aged, pine-hardwood stand. Disturbances were: (1) seedbed conditions averaging 56, 16, 9, and 17 percent ...
Onion is commonly established in the field either by direct sowing, or transplanting seedling from seedbed sets depending on growing conditions of specific region and grower interests. However, optimum age onion areas Ethiopia not well done. Field experiment was conducted at Alawuhakebele North Wollo zone to optimize varieties 2021/2022 cropping season under irrigation. Adama Red, Bombay Red Na...
A goal in sustainable agriculture is to use fossil energy more efficiently crop production. This 60-year-old experiment on a silt loam chernozem investigated effects of fertilization (unfertilized control, mineral fertilizer (NPK) and farmyard manure (FYM)) rotation (continuous winter rye (CR), (RR), spring barley (SB) diesel fuel consumption, total input (made both direct indirect inputs), yie...
