The effect of drip irrigation regimen on growth, physiological parameters, and crop yield in Cucumis sativus L. was investigated using a drip irrigation system. The experimental design comprised eight various water regimens (2, 4, 6, 8, 10, 12, 14, and 16 L·h−1). Plants received water five times a day, making a total of 10, 20, 30, 40, 50, 60, 70, and 80 L per day. Growth and photosynthetic parameters were analyzed on a weekly base for a period of 8 weeks. Crop yield was measured at the end of the experiment. In general, photosynthetic rate (A), intercellular CO2 concentration (Ci), stomatal conductance (gS) and the transpiration rate (E) of the cucumber plants were enhanced by increasing water quantities compared with the control. Overall, the total chlorophyll content was significantly enhanced between week 7 and 8 in plants treated with high irrigation volume. Significant improvements were recorded in plant height and number of leave from week 3 to 8 in plants supplied with high irrigation volume. The observed increase in photosynthetic parameters, chlorophyll contents, and plant growths perhaps accounted for the significant increase in the number of marketable fruits in cucumber grown in higher water regimen. The optimal yield of cucumber in the present study was attained in plants irrigated with water regimen ranging from 40 to 80 L per day. The results of this study present valuable information that cucumber growers in South Africa should adopt the use of drip irrigation technique to save water considering the high drought condition in the country.

Mulched Drip Irrigation

It is a world-wide concerned problem to more efficiently use water resources in agricultural production, and it becomes a hot issue to adopt a more water and fertilizer-saving in grain production. Focusing the main rice producing areas in Inner Mongolia during 2018-2019, this study analyzed the growth stage and morphological characteristics (plant height and root system) of the rice through mulched drip irrigation aerobic rice plot. And the yield of aerobic rice and the factors affecting the yield, as well as evaluated the economic benefit indexes (income and cost) of mulched drip irrigation aerobic rice were discussed. The results showed that the seedling emergence rate of mulched drip irrigation aerobic rice was 4.1% lower than that of traditional transplanting rice, and the root length, average diameter, surface area and volume were lower than those of traditional rice. In addition, the rice with higher plant height and more panicle would get less grain, while more effective tillers and larger 1000-grain weight would get better yield. Compared with conventional rice cultivation, mulched drip irrigation maize and soybean, mulched drip irrigation aerobic rice has significant increase in production and efficiency.

Abstract. In psychology, thinking is typically studied in terms of a range of behavioral or physiological parameters, focusing, for instance, on the mental contents or the neuronal correlates of the thinking process proper. In the current article, by contrast, we seek to complement this approach with an exploration into the experiential or inner dimensions of thinking. These are subtle and elusive and hence easily escape a mode of inquiry that focuses on externally measurable outcomes. We illustrate how a sufficiently trained introspective approach can become a radar for facets of thinking that have found hardly any recognition in the literature so far. We consider this an important complement to third-person research because these introspective observations not only allow for new insights into the nature of thinking proper but also cast other psychological phenomena in a new light, for instance, attention and the self. We outline and discuss our findings and also present a roadmap for the reader interested in studying these phenomena in detail.
