Abstract: Productivity of wheat was low due to depleted soil fertility and the blanket use of fertilizers. Fertilizer is the most vital input, contributing significantly to final wheat yields although wheat yields have long been low due to a lack of soil test-based site-specific fertilizer recommendations. This study aimed to determine an economically appropriate rate of NPS fertilizer based on calibrated Phosphorus for bread wheat production in the Degem district. The experiments laid out in randomized complete block design (RCBD) with three replications. The treatments were based on already determined Phosphorous critical and requirement factors and consisted of 100% Pc from TSP fertilizer, 25%, 50%, 75%, and 100% Pc from NPS fertilizer and control (without fertilizer). The phosphorus requirement factor (Pf) (5.85), phosphorus critical (Pc) (22 ppm), and optimum nitrogen optimum nitrogen (92 kg ha-1) were used from previous studies. Improved bread wheat variety senete was used at 150 kg/ ha seeds rate. The results of a statistical analysis of variance demonstrated that NPS fertilizer rates based on calibrated phosphorus had significant effects on bread wheat production. Partial budget analysis shows the maximum net benefit (101,570.65 Birr ha-1) with an acceptable marginal rate of return (MRR) (932’52 %) through the application of 75% of Pc from NPS with optimum nitrogen fertilizer use. Consequently, 75% Pc from NPS should be used in the Degem district for bread wheat production, with the optimum nitrogen. Thus, further scaled-up and demonstration of the technologies for bread wheat production in the Degem district.

Abstract: The Chinese giant salamander (Andrias davidianus), the American giant salamander (Cryptobranchus alleganiensis), and the Japanese giant salamander (A. japonicum) are precious aquatic protected animals that currently exist in the world. The latter two cannot be traded locally, whether wild or cultivated, and can only be protected, so they have not formed an industry. However, China allows the second generation of artificially bred offspring giant salamander to be traded and has already formed a factory scale breeding. The Chinese giant salamander has high economic value in food, health, medicine, beauty and other fields. In recent years, its artificial breeding industry has been widely developed in China and has a certain industrial scale. However, there are also many problems in the development of the giant salamander industry. In order to promote the high-quality development of the giant salamander industry and improve its quality, this article conducts research on the giant salamander industry, identifies existing problems, and provides suggestions. Firstly, this article analyzes the problems in the development process of giant salamanders from multiple perspectives, including management, service, market, research and development, and brand awareness. Secondly, corresponding industrial development strategies are proposed, including increasing regulatory efforts, enhancing service awareness, building market order, expanding sales channels, increasing research and development investment, reducing disease occurrence, extending the industrial chain, and strengthening brand awareness. Finally, the prospects for the development of the giant salamander industry are discussed.

Abstract: Maize is an important food crop in Ethiopia and it is one of the main smallholder food crops in the rift valley of Oromia, although shortage of rainfall and erratic occurrence was caused soil moisture content stressed yields reduced. Suitable soil and water conservation measures that can be easily integrated into the existing farming operations while enhancing in-situ moisture conservation. The study was conducted on land surface management to increase soil moisture content, amend soil nutrients and enhance yield and yield components of maize. The experiment was conducted during the 2021 and 2022 main cropping seasons at Adami Tulu Agricultural Research Center on-station using RCBD that had five tested treatments. Maize variety Melkasa-II was used as a testing crop for its familiar to local communities. The results indicated that soil moisture content was enhanced by 5.8% to 26.4% in maturity and vegetative stages up to 60 cm depths. Soil physico-chemical properties were improved and the highest grain yield was obtained from 5 tha-1 (SM+FYM) plus NPS fertilizer and 5 tha-1 of straw mulch plus inorganic fertilizers treatments that increased by three to four fold of the organic fertilizer applied and control treatments orderly. This result implies that retaining crop straw mulch and application of farmyard manure in the field within profitable cost can be used as soil moisture conservation tool for sustainable improvement of maize production in the study area.
