Drought is a serious threat to cotton growing. This study aims to evaluate effect of hydropriming on seed germination of two varieties of cotton, STAM 129A and STAM 190, under drought stress. Seeds are primedfor3, 6, 9, 12, 15 and 18 hours. The germination test was carried out in 90 mm Petri dishes, at 0, -3, -6 and -9 bar adjusted by PEG-6000, and lasted 7 days. Germination percentage (GP), mean germination time (MGT), germination index (GI) and the relative PEG injury rate (RPIR) was then calculated.

There is a wide genetic variability of cucumber in different parts of India. Performance evaluation of the different genotypes for growth and yield attributes is a prerequisite for any breeding programme. Hence, studies have been conducted at the Department of Vegetable Science, Horticultural College and Research Institute, TamilNadu Agricultural University, Coimbatore, TamilNadu, India from 2020 to 2023 to evaluate different genotypes collected from different parts of TamilNadu to find the suitability of cucumber for salad and slice (fruit) purpose.

Agriculture is a vital sector in both China and Tanzania, contributing significantly to their economies and supporting numerous livelihoods. However, it faces challenges like climate change, resource limitations, market access issues, and technological advancements. This interdisciplinary analysis combines economic factors, basic agricultural principles, information services, and policy analysis to comprehensively study agricultural information services in both countries. The results have the potential to guide future policy decisions.

Trained human resources are needed to prevent food safety hazards along the food chain. A survey of food science undergraduate teams from six universities in Sri Lanka was conducted to assess food safety knowledge at two points in the food chain, food processing and catering. The questions on food processing assessed exposures of the undergraduates in classes and outside. A second assessment addressed the application of food safety knowledge in food preparation and catering management. Six teams of 5 undergraduates each answered the food processing questions.

Water quality and its availability have implication on the health status and lifestyle of a community. Over 80% of preventable disasters, diseases, hunger and even deaths are due to improper utilization and management of water. Flooding, orchestrated by climate change has exacerbated the situation. Children below the age of 5 years old are highly vulnerable and most affected by these waterborne diseases. The pattern of water-borne diseases in relation to water quality and other environmental factors was studied among residents of Igbesa in Ado Odo-Ota LGA of Ogun state, Nigeria.

Summary: In Congo, rice yields remain low. To better determine the productivity of the panicle in rice varieties, following the different treatments of the mineral nutrition background, it was established that there is a considerable influence of the contributions of nitrogen and carbon compounds coming from the vegetative organs of the plant. Methodology and results: Three treatments were applied (N12 P6 K6), (N24 P12 K12) and (N 36P 18K18) on the two (2) varieties Nerica 14 and Nerica 12.

Wheat is an important field and food crop worldwide and in Sudan it is grown in many areas using different types of cultural practices. A field experiment was conducted in Dongola Agricultural Research Farm, Northern State, for two successive seasons to investigate the effect of three leveling techniques; Laser (L), Scraper (S) and traditional (T); three type of ploughing; heavy disc harrow (H1), disc plough (H2) and no-ploughing (H3), and two sowing methods; seed drill machine (S1) and manual seed broadcasting (S2)on wheat production.

In Dacryodesedulis (G; Don) H. J. Lam L and Elaeis guineensis Jacq. Are two fruit species used for food. In Brazzaville, they are among the most representative and cover the entire city. The phonological study of these two species was carried out throughout the city of Brazzaville. The aim of the study is to improve phenological knowledge of these species. The methods used are based on field surveys. The trees selected, marked and geolocated were monitored using the observation method for two years. The various results obtained show that in Dacryodesedulis (G. Don) H. J.

In this paper, we present a numerical analysis of natural convection and the effects of collector radius variation on the velocity and temperature field. After transforming the conservation equations of mass, momentum and energy, we compare the results of our calculation code with those of Comsol. On the one hand, the comparative study of the temperatures in the collector reveals a slight difference at the entrance to the chimney, on the other hand we note that there is a perfect agreement with the general appearance of the evolution curves temperatures in the chimney.
