Afield experiment was carried out from 2011 to 2018 cropping seasons at experimental site of Gera agricultural research sub-center to investigate the effect of soil moisture depletion and to identify optimal soil moisture depletion level on growth, yield and water productivity of coffee Arabica (coffee Arabica L.) of variety 74165. The treatments consists of five allowable soil moisture depletion level (ASMDL), i.e, 60% ASMDL, 80% ASMDL, 120% ASMDL, 140% ASMDL and control irrigation of 100% ASMDL. These five treatments were laid out in complete randomized block design with three replications. The irrigation water was applied based on allowable soil moisture depletion of (p=40%) considered for coffee Arabica. The over year analysis of variance showed that soil moisture depletion level significantly (P<0.05) affected coffee yield and water productivity. The average highest coffee yield of 2330 Kg/ha was obtained from the 120% ASMDL by applying 10145 m3/ha of water, while the FAO recommended treatment of 100% ASMDL produced the lowest yield of 1780 Kg/ha. The 60%, 80%, 100% and 140% treatments were not statistically significant from each another. Therefore, 120% ASMDL treatment gave above mean value of yield and water productivity and hence can be used as the allowable soil moisture depletion for coffee Arabica (coffee Arabica L.) in a coffee growing area of Gera.

Common bean is playing a crucial role across the world mainly in the warm and lowland areas of the country including Ethiopia. Understanding the level of drought tolerance of the varieties available in each country is of paramount importance for breeding common bean for drought adaptation. However, the production of common bean is mainly limited due to lack of high yielding potential varieties and frequent and recurrent drought. Hence, the study was aimed to evaluate and identify the superior performance and genetic potential of improved common bean varieties for yield and yield related traits against drought. A total of 10 recently released improved common bean varieties were evaluated using a randomized complete block design (RCBD) with three replications at Mieso during the main cropping season of 2018 and 2019. The information generated on the drought tolerance of the available varieties should help in the design of a breeding strategy that incorporates adaptation traits with commercial characteristics preferred by common bean farmers for varieties to be grown in diverse environments. The combined analyses of variance revealed the presence of tremendous genetic variation among improved common bean varieties for all the studied traits except plant height and stand count at harvest, which implies the availability of substantial genetic variation among varieties. Overall, SER-125, SER-19 and Nasir common bean varieties had better performance compared to the other varieties for yield and the yield related traits. The maximum grain yield was obtained from SER-125 (2620 kgha -1 ) followed SER-19 (2612 kgha -1 ) and Nasir (2583.33 kgha -1 ) common bean varieties and identified as the superior improved common bean varieties. Eventually, the effect of varieties on grain yield was significant and the best performing varieties of common bean would be recommended for the specific community and its vicinity even though further study should be carried out including a number of recently released varieties for improved common bean production in the target area and also to put the recommendation on strong basis. Therefore, based on the results of this adaptation experiment, SER-125, SER-19 and Nasir were recommended for production and adoption at Mieso and other similar environments.

Field experiments were conducted during 2014 and 2015 to evaluate the effects of residual organic fertilizers with supplemental inorganic fertilizers on performance of subsequent maize crop and soil chemical properties at Field 2, Faculty of Agriculture, Universiti Putra Malaysia, Serdang, Selangor, Malaysia. In the first season, the trial was conducted by using 4 nutrient management treatment (control, 100% poultry manure (PM), 100% NPK and 50% NPK + 50% PM) in 3 cropping system (sole maize, sole soybean and maize + soybean intercropping). The following trial was conducted by using the first experimental plot. After harvest of the crops in the first experiment, the biomass was left and incorporated manually into the soil before planting the subsequent maize crop. The experiment comprised of 14 treatments, 12 based on the first experiment and two additional treatments for comparison (control and 100% NPK). The treatments were laid down in a randomized complete block design (RCBD) with three replications. The results showed that all fertilizer treatments increased growth, yield and yield components of the subsequent maize crop. However, incorporation of maize residue alone was ineffective in increasing yield of the subsequent maize crop. The combination of crop residue with residual PM enhanced soil pH, organic matter and nutrient availability in the soil. The combined application of soybean residue + 50% residual PM + 50% phosphorous and potassium (PK) fertilizer and soybean residue + 100% PK gave maize yield same level as 100% NPK. Therefore, it can be recommended that substitution of 50% inorganic fertilizer with residual PM and substitution of N fertilizer in soybean residue is recommended to increase yield of maize and improve soil chemical properties.

Rats and mice are not only a nuisance but can also cause property damage and transmit diseases. You’ll know they’ve arrived if you see rodent droppings near a food source or shredded fabric or paper. If you identify rodents, there are several steps to take to ensure permanent removal of these pests. Removing rodents with traps or poisons will not keep rodents out of your home in the future. To permanently keep rats and mice out of your home or business, you will need to prevent access by sealing all possible entry points. It is equally important to eliminate rodent attractions such as food and water by keeping food in tightly sealed containers and repairing leaky pipes.

Rice (Oryza sativa L.) is the most important food security crop for about half of the world’s population (Brohi et al., 1998) and ranks third in area after wheat and maize and second both in production and productivity after maize worldwide (FAOSTAT, 2012). The total world rice production has risen steadily from about 200 million tons (1960) to over 678 million tons (2009) (USDA, 2012). In the 2010/2011 and 2011/2012, the world paddy productions were estimated at 691.3 and 713.8 million tons, respectively. Globally, 158.9 million hectare of rice was harvested during the 2011/2012 (USDA, 2012). Rice represents 29% of the total output of grain crops worldwide (Xu et. al., 2003).These yields are compared with the world average of about 3.8 tones/ha; it is evident that there is a lot of potential to improve rice yields worldwide. Over 90% of the world’s total rice crop is produced in South and East Asia. In area and production, China is the leading country in the world (EUCORD, 2012).

Stevia rebaudiana Bertoni, known as the "sweetest plant of the world", belongs to the family Asteracea and is native to the South American center of diversity. The world of sweetness has seen a sweeter change in the recent past with the introduction of stevia sugar obtained from leaves of stevia containing compounds about 250 to 300 times sweeter than the table sugar (Kumar, 2002). The substance of interest is stevioside, rebaudioside A and at least six other compounds that have glucosidal groups attached to a three-carbon ring central structure. Stevioside could be equivalent to the sweetening power of 28 tons per acre of sucrose sugar (Shock, 1982). Though these sugars have sweetening qualities, they have been found to contribute to calories and are not advised for the consumption by diabetic patients.

Rice (Oryza sativa L.), is one of the most important food crops and is considered as a major source of calories for more than half of the global population (Carrijo et al., 2017), covers 11% of total arable land (Khush, 2005). Rice has become a commodity of strategic significance across many African countries (Hegde and Hegde, 2013). It is also the most rapidly growing food sources across the continent due to the great urbanization in Africa more than any other region in the world.
