PDCA – Hogyan tanul a szervezet?

open access: yesInternational Journal of Engineering and Management Sciences, 2016
Egy szervezet (legyen az profitközpontú vagy versenyszférán kívüli) tudja, hova akar eljutni (jövőkép). Ez történhet szándék szerint megvalósult stratégia mentén, de lehet fokozatosan kifejlődő stratégia eredménye is. A stratégia vagy korábban kialakult

Farmers' Subjective Perceptions of Yield and Yield Risk [PDF]

open access: yes, 2006
Using survey responses of Illinois corn farmers to differently framed yield questions, we examine their subjective information by relating stated yields and risk to the corresponding objective county measures. The results show that farm-level yields can be best characterized by soliciting probabilistic information, which provides more accurate yield ...

Climate variation explains a third of global crop yield variability

open access: yesNature Communications, 2015
Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive.

The role of pruning in the intensification of plum production

open access: yesInternational Journal of Horticultural Science, 2006
In an orchard planted in the spring of 1997, four kinds of spacing have been applied (4.0 m x 1.5 m, 4.0 m x 2.0 m, 5.0 m x 2.5 in and 6.0 m x 3.0 m). Four cultivars (‘Cacanska lepotica', Stanley' ‘Bluefre' and ‘President') grafted on Myrobalan rootstock

Variability of yield and yield components in “egusi” melon [PDF]

open access: yesAfrican Crop Science Journal, 2011
Egusi melon (Citrullus lanatus (Thunb.) Mansf.) is an important food crop in Nigeria and other African countries. In a study carried out to estimate the components of variation in ‘egusi’ melon populations indicated high proportion of genetic variation in the yield attributes measured. Estimates of phenotypic coefficient of variation ranged between 3.6-

Effect of Deficit Irrigation on Yield and Water Use Efficiency of Maize at Selekleka District, Ethiopia [PDF]

open access: yes, 2020
Irrigation water availability is diminishing in many areas of the Ethiopian regions, which require many irrigators to consider deficit-irrigation strategy. This study investigated the response of maize (Zea mays L.) to moisture deficit under conventional,

Waste apple wood: A safe and economical alternative substrate for the cultivation of Pleurotus ostreatus and Lentinula edodes

open access: yesFolia Horticulturae, 2022
The use of waste apple-wood as a source of sawdust to cultivate the mushrooms Pleurotus ostreatus and Lentinula edodes is a common practice, but it is imperative to ensure that the wood does not contain unsafe amounts of heavy-metals or pesticide ...

Excessive rainfall leads to maize yield loss of a comparable magnitude to extreme drought in the United States

open access: yesGlobal Change Biology, 2019
Increasing drought and extreme rainfall are major threats to maize production in the United States. However, compared to drought impact, the impact of excessive rainfall on crop yield remains unresolved.

Development of species composition in long term simulations with an individual-tree growth simulator

open access: yesJournal of Forest Science, 2009
The spruce-fir-beech dominated forest stands in Litschau in the Austrian part of the Bohemian Massif were converted by former forest management practices into pure Norway spruce stands and are now discussed to be reconverted into the potential natural ...

Growth of High Quality GaN on Si (111) Substrate by Using Two-Step Growth Method for Vertical Power Devices Application

open access: yesCrystals, 2021
A crack-free GaN film grown on 4-inch Si (111) substrate is proposed using two-step growth methods simply controlled by both III/V ratio and pressure. Two-step growth process is found to be effective in compensating the strong tensile stress in the GaN ...
