ABSTRACT: This study was conducted during February and May 2016 at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat (Longitude 32o 32` E, Latitude 15o 40` N and Altitude 380 m amsl), on a total area of 40m× 30m, with the objective of determining water distribution efficiency due to the effect of different weather conditions during three periods in the day (morning 08:00- 09:00 a.m., mid-day 12:00 - 02:00 p.m., evening). The study also included determination of Christiansen's coefficient of uniformity (CU%) and the distribution uniformity (DU%) for each of the above mentioned periods under two operating pressures of 1.0 and 2.0 bar and two riser heights of 1.0 and 1.5 m. Plastic sprinkler heads (LEGO) sing1e nozzle type were used .The experiment..........

ABSTRACT: This study reveals the effect of 300g of mild steel buried in different levels of crude oil( 0, 40, 80, 120 and 160ml ) polluted soils (3kg) on the growth response of two maize (ZeaMays L.) varieties. The plant height, leaf length, and leaf number were measured. There was a gradual increase in the growth parameters with age in soils with low levels (0, and 40ml) of treatment. The higher the treatment levels, the higher the corrosion of mild steel, and the higher the iron content in the soil. There was higher chlorosis and reduction in leaf size in the 160ml crude oil treatment in the white maize compared with the yellow maize. This could be as a result of the penetration of oil into the plant tissues and highly corroded and dissolved iron in the soil matrix. It was therefore, concluded that crude oil/ iron stress...........

ABSTRACT: The present experiment entitled "Genetic variability, Correlation and Path analysis for yield and yield components in F6 generation of wheat (Triticum aestivum L.Em. Thell.)" Was conducted in Rabi 2015-16 at the Field Experimentation Centre of the Department of Genetics and Plant Breeding, SHUATS, Allahabad. The experiment was carried out in augmented design with three (3) blocks to obtain information on estimates of variability, correlation coefficient and path analysis among 19 genotypes of wheat. Analysis of variance revealed that there was significant differences among........

ABSTRACT: Biochemical methane potential (BMP) test is a useful laboratory-scale tool to determine the biodegradability and methane potential from different manure. The aims of this study were to evaluate the BMP of sheep manure and the elimination of pathogens after going through anaerobic digestion. The BMP was carried out in mesophilic temperature (35ºC) with a substrate/inoculum (S/I) ratio of 0.5 gSV/grSV. At the beginning and in the end of the experiment the following variables were determined, pH, total and soluble chemical oxygen demand (CODT and CODs respectively), total ammonia nitrogen (TAN), free ammonia nitrogen (FAN), volatile fatty acid (VFA), partial.......
