Estimation Of Storage Tank Capacities For Different Roofing Areas For Rainwater Harvesting In Dodoma Urban, Tanzania, Ombeni J. Mdee
Tanzania Journal of Engineering and Technology (TJET)
This study uses a mass balance model and economic analysis technique to present an estimation of roofing areas and storage tank capacity for Rainwater Harvesting (RWH) system. The water-saved benefits were estimated using the monthly rainfall of over 39 years from 1981 to 2020 and five roofing areas. The proposed roof-storage-ratio method presents the minimum requirement of roof area and storage tank size when the ratio value is closer to 1. The benefit-cost ratio and percentage of reliability indicated the optimal roofing areas ranging between 200 and 300 m2 for storage tank capacity between 20 and 25 m3, with a …

The world’s agricultural production is declining due to severe loss of soil fertility through natural processes or because of human activities. Biochar has been identified as a potential soil amendment to regain its fertility and increase crop productivity. This study aimed to assess the effects of biochar on soil nutrients and crop yields in the southern highlands of Tanzania. Data were collected through key informant and household interviews, and from sampling of soils in coffee farms where biochar of maize cobs origin was incorporated at the rate of 3 t ha-1.

Extreme weather conditions associated with climate change affect many aspects of plant and animal life, including the response to infectious diseases. Production of salicylic acid (SA), a central plant defence hormone, is particularly vulnerable to suppression by short periods of hot weather above the normal plant growth temperature range via an unknown mechanism. Here we show that suppression of SA production in Arabidopsis thaliana at 28 °C is independent of PHYTOCHROME B (phyB) and EARLY FLOWERING 3 (ELF3), which regulate thermo-responsive plant growth and development. Instead, we found that formation of GUANYLATE BINDING PROTEIN-LIKE 3 (GBPL3) defence-activated biomolecular condensates (GDACs) …

Boreal mixed forests of trembling aspen (Populus tremuloides) and white spruce (Picea glauca) can provide higher outputs of many ecosystem goods and services, combined with resilience for changing environmental conditions. In this study, we examine the growth of white spruce and aspen over a range of stand compositions created by spot and broadcast treatments of broadleaves using manual and chemical means, aspen spacing, and untreated control. Twenty-two growing seasons postharvest, treatment responses created a range of broadleaf densities and spatial arrangements, reflected in significant differences in heights and diameters of the spruce mixedwood component.

Different methods such as physical, biological and chemical are used to manage soil fungus increasing termites. Synthetic insecticide plays a vital part in the management of termites. The pesticide used in big quantities causes phytotoxicity, mammalian toxicity and resistance to pesticides in target pests and insect outbreaks. Intensive pesticides exert chronic effects on living organisms with annoyance for beneficial insects. It also accompanied with environmental hazards and developed resistance. Plant leaves extracts provide a distinct variety of biochemical compounds with diverse prospective uses. Resistance development requires the discovery of fresh biological compounds with a wide spectrum of action. Plant leaves …

Soils have the most diversified microbial communities of any environment on the planet. Bacteria, fungi, algae, and protozoa are all found in abundance in soil. Maintaining a healthy environment for crops requires a strong link between plants and soil microorganisms that are essential for good crop development. Soil bacteria are key regulators of the nutrient cycle. Mineralization, legume nitrogen fixation, and ammonia conversion to plant-available nitrate would all be impossible without bacteria. Effective microorganisms have the ability to boost crop growth and yield. When used in conjunction with organic amendments, these bacteria performs better than to the sole application. It …

Fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) is most destructive specie of genus Spodoptera for several agricultural crops. In Pakistan's Sindh province, the invasive fall armyworm Spodoptera frugiperda was first documented causing serious maize damage in 2019. There is need to develop management strategies against this pest in the country. The current study was conducted to check the toxicity of different insecticides against FAW in maize field. The results showed among tested insecticides, deltamethrin was recorded most toxic insecticide followed by chlorantraniliprole and emamectin benzoate. At 1d days after first spray, least number of larvae were recorded with deltamethrin (0.07 …

Salinity causes a detrimental impact on plant growth, particularly when the stress occurs during germination and early development stages. Barley is one of the most salt-tolerant crops; previously we mapped two quantitative trait loci (QTL) for salinity tolerance during germination on the short arm of chromosome 2H using a CM72/Gairdner doubled haploid (DH) population. Here, we narrowed down the major QTL to a region of 0.341 or 0.439 Mb containing 9 or 24 candidate genes belonging to 6 or 20 functional gene families according to barley reference genomes v1 and v3 respectively, using two DH populations of CM72/Gairdner and Skiff/CM72, …

Rosen Research Review
What’s better than simply drinking wine in a vineyard? Maybe a beautiful destination where the whole family can enjoy a day together, tasting wine, enjoying a variety of activities, and watching the kids play. Dr. Robin Back at the UCF Rosen College of Hospitality Management and his collaborators have examined a case example that presents a new business model for wine tourism—micro-clustering with diverse forms of ownership on two adjacent wine farms. The team reveals how a single South African agribusiness achieved success, and raises the possibility of other similar businesses doing the same.

Revegetation of boreal forest lands disturbed by surface mining for bitumen can be challenging due to fluctuating levels of soil NaCl and harsh winter temperatures. These stressors may hinder the growth and survival of planted tree seedlings. Two experiments were carried out to examine the processes of recovery from NaCl stress and overwintering in trembling aspen, tamarack, and white spruce seedlings. In the recovery experiment, seedlings were treated with 0, 50, or 100 mM NaCl for 60 days and then allowed to recover for 60 days. Most of the examined physiological variables (total dry weight, chlorophyll concentration, photosynthesis, and transpiration) …

A multi-state and interdisciplinary team was formed to address the Extension and research needs of CLRDV, an emerging cotton disease with high potential impact for U.S. cotton production. In 2017, CLRDV was identified in AL and Auburn University immediately formed an interdisciplinary working group composed of plant breeders, plant pathologists, entomologists, and agronomists. Since then, scientists from ten other states have joined the CLRDV group. Thus, allowing research to be coordinated efficiently and best deploy limited resources to attend the stakeholder’s needs. The CLRDV group produces and shares new and relevant information with the scientific community and cotton producers alike.
