AbstractBread wheat (Triticum aestivum L.) is one of the most important cereal crops in Ethiopia. The productivity of wheat is markedly constrained by nutrient depletion and inadequate fertilizer application. The experiment was conducted to study the effect of nitrogen (N) and potassium (K) fertilizer rates on growth, yield, nutrient uptake and use efficiency during 2019 cropping season on Kedida Gamela Woreda, Kembata Tembaro Zone Southern Ethiopia. Factorial combinations of four rates of N (0, 23, 46 and 69 kg Nha−1) and three rates of K2O (0, 30 and 60 kg Nha−1) in the form of urea (46–0-0) and murate of potash (KCl) (0-0-60) respectively, were laid out in a randomized complete block design with three replications. The results showed that most parameters viz yield, yield components, N uptake and use efficiency revealed significant differences (P < 0.05) due to interaction effects of N and K. Fertilizer application at the rate of 46 N and 30 kg K ha−1 resulted in high grain yield of 4392 kg ha− 1 and the lowest 1041 from control. The highest agronomic efficiency of N (52.5) obtained from the application of 46 kg N ha−1. Maximum physiological efficiency of N (86.6 kg kg−1) and use efficiency of K (58.6%) was recorded from the interaction of 46 and 30 kg K ha−1. Hence, it could be concluded that applying 46 and 30 kg K ha−1was resulted in high grain yield and economic return to wheat growing farmers of the area. Yet, in order to draw sound conclusion, repeating the experiment in over seasons and locations is recommended.

Scarcity of water is the most severe constraint for sustainable development of agriculture in arid and semi-arid areas. Hence, novel irrigation water application systems need to be developed so that high crop yield and water productivity per unit of land can be increased. Thus, the field experiment was conducted with the objective of determining the effect of different soil moisture depletion levels on yield and water use efficiency of sorghum crop in Benna-Tsemay woreda at Enchete kebele, Southern Ethiopia. The experiment was conducted for two consecutive years (2019-2020). It was arranged in RCBD with three replications and treatment was rated for five levels of available soil moisture depletion (ASMD), where T1 = 60%, T2 = 80%, T3 = 100%, T4 = 120%, and T5 = 140% of ASMD. Analysis of variance has shown that yield and water use efficiency of sorghum crop was significantly (P < 0.05) affected by irrigation scheduling. As observed in this study, the most economically attractive and environmentally accepted for small scale farmers with tolerable cost of production and higher net benefit was obtained by application of T3 (100% ASMD) under conventional furrow irrigation system. Therefore, for this particular sorghum crop (teshale variety), it could be concluded that increased water saving and water productivity through irrigation at 100% ASMD under conventional furrow irrigation system can solve the problem of water shortage and would ensure the opportunity of further irrigation development in the study area and similar agro-ecology.

The Impact

There have been significant decreases in the aggregate energy intensity of industry in China, Korea and Taiwan since 1980. We decompose changes in this often-used energy performance indicator into contributions associated with industry product mix and sectoral energy intensity. In all cases, the results obtained show a large effect of changes in sectoral energy intensity and a relatively smaller effect of changes in product mix. We further decompose the sectoral energy intensity effect to identify the impact of fuel substitution. It is concluded that decreases in the aggregate energy intensity of industry in the three economies were due primarily to improvements in fuel use efficiency.

Field experiment was carried out during the 2017-18 cropping season at Kako, Bena-Ttsemay woreda, South Omo zone, Southern Ethiopia to determine the effect of intercropping of maize and cowpea on the yield, land use efficiency and profitability of both crops. The experiment consisted of 4 treatments (sole maize, sole cowpea, one row maize to one row cowpea and one row maize to two-row cowpea) and laid in RCBD in four replications. Intercropping of one row maize to one row cowpea and one row maize to two-row cowpea, resulted in 55.8% and 27.9% greater land use efficiency than for either crop grown alone. The highest MAI was obtained by growing one row of maize to one row of cowpea (11563.17) followed by one row maize to two-rows of cowpea (6783.50).Based on the present finding, intercropping of one row maize and one row cowpea more economic advantage than the other crop combination or grown alone. Therefore, intercropping of one row maize to one row cowpea is an advantageous to farmers in the study area since it would provide additional crop yield with the same piece of land and more profitable related to cost benefit.

Highlights Principal component analysis found the impact of controlled and uncontrolled drying system variables. Cotton gin fuel use can be minimized by avoiding excessive drying and minimizing conveying air. Post-harvest processors should minimize the length of, and insulate, the duct from the burner to the mix point. Abstract. Fuel price volatility and variable incoming cotton moisture levels make drying costs unpredictable, threatening cotton gin profitability. One means for managing this risk is improving fuel use efficiency. Fuel use audits were conducted in 26 commercial cotton gins over three seasons to elucidate industry best practices. Material flow and changes in moisture content were used to estimate beneficial drying energy. Airflow and temperature data were used to estimate fuel consumption. The ratio of these quantities, defined as fuel use efficiency, was included with twelve other variables in a multivariate statistical analysis. Principal component analysis identified two controlled variables that inversely correlated to fuel use efficiency: the length of the duct between the burner and the seed cotton mix point, and the volume of conveying air per unit mass of seed cotton. Minimizing these two variables could reduce the cost of fuel energy, provided that the air volume is sufficient to maintain material flow, drying, and gin processing rate even when receiving very wet cotton.
