Greenhouse crops production has been improved by CO2 enrichment commercially. The impact of a threshold level elevated (e[CO2]) on the effective quantum yield photosystem II (ФPSII, chlorophyll fluorescence parameter), which is linked to crop yield, growth and fruit quality, still uncertain. Many previous studies cultivated C3 under 550–700 µmol·mol-1, not beyond this range. Hence, tomato plants were grown ambient (a[CO2], 500 µmol·mol-1) e[CO2] (700, 850, 1000 µmol·mol-1): named as EC700, EC850, EC1000, respectively, uniform environmental conditions for two growing seasons investigate response ФPSII along with four photosynthetically active radiation intensities plant continuous concentration [CO2]. Under constant PAR during autumn-winter 2020 spring-summer 2021, order mean values explored EC700 > EC1000 EC850 a[CO2] a[CO2], respectively. optimum total was stimulated 74.04% 55.86% compared a[CO2]. results showed that water use efficiency related (WUEy) enhanced reducing stomatal conductance Optimum WUEy 55.91–210.87% principal component analysis strong correlation height, in LAI weak stem diamter indicated effect e[CO2]. 2021 found more influential analytic hierarchy process get production, no significant difference between ranking scores found.

The biochar application has been reported to have a positive effect on crop yield and nutrient utilization. However, the effects of joint nitrogen (N) soil physical properties, fruit yield, quality, water productivity (WP) partial factor (PFPN) water-stressed greenhouse tomato under drip fertigation remain poorly understood. In this study, two-season experiment was conducted in autumn 2021 spring 2022, involving two rates (0 30 t ha–1 only first season before sowing), N fertilization (175 250 kg ha–1), three irrigation levels (100%, 75%, 50% evapotranspiration). results showed that significantly decreased bulk density by 7–13%, but increased porosity 5.5%− 10% 43.2–73.8% compared with non-biochar treatment. affected total soluble solids (TSS), sugar (SS), vitamin C fruits. interaction PFPN WP 67.4% 76.3% 2021, 38.1% 51.8% respectively. Biochar rate level had significant TSS SS contents both seasons, seasons. application, yield. rate, were growing enhanced quality water-nitrogen tomato. Principal Component Analysis (PCA) revealed PC1 accounted for 47.7% 48%of variation while PC2 14.6% 15.6% This study underscores significance drip-fertigated cultivation highlights its sustained next season.

A Novel Multipurpose Self-Irrigated Green Roof with Innovative Drainage Layer

Hydrology, Год журнала: 2023, Номер 10(3), С. 57 - 57

Опубликована: Фев. 25, 2023

Climate change is a significant problem that many countries are currently facing, and green roofs (GRs) one of the suitable choices to confront it decrease its impacts. The advantages GRs numerous, such as stormwater management, thermal need reduction, runoff quality, life quality improvement. However, there some limitations, including weight, limits in water retention, irrigation drought period, suitability harvested for building usages, installation on sloped roofs, high cost. Therefore, developing novel system design with higher efficiency fewer negative points seems necessary main scope this research. In regard, multipurpose self-irrigated roof an innovative drainage layer combined specific multilayer filters has been developed. application proposed terms retention capacity, storage volume, treatment performance, system, layer, domestic purposes, other aspects analyzed compared conventional systems focus extensive roofs. results demonstrate would have less weight due replacement gravel pipeline network storage, capacity design, impacts existence can be changed periodically, easier flat possibility using collected rainfall use, demands sub-surface self-irrigation system.

Horticulture Irrigation Systems and Aquaculture Water Usage: A Perspective for the Use of Aquaponics to Generate a Sustainable Water Footprint

Опубликована: Май 9, 2024

The expansion of food production is getting more important due to a rising world population, which relying on security regional and local scale. Intensive systems create negative impact the ecosystem because agrochemical pollution nutrient rich water discharges into nearby rivers. Furthermore, these are highly depending resources causing scarcity soil erosion overexploitation natural in general. objective this article review usage two most intensive systems, agriculture aquaculture showing lacking areas, like system management climate change, must be considered implementation sustainable footprint. In addition, includes an analysis if combination both aquaponic possibilities saving. There variety footprint analyses for crop aquatic animal production, but there also lack information about including irrigation cleaning processes, substitution, pond removal, evaporation change especially aquaculture, industrial elaborated fish feed.
