Abstract: A field experiment was conducted during the “Bona” season of 2016 at Bale highland agro ecology and environment to optimizing fertilizer rate recommendation for major cereal production systems by using wheat as test crop. Experiment was laid out in a randomized complete-block (RCBD) design with three replications for sixteen (16) treatments were conducted. It was found that the amount of N application in plants had significant difference between treatments applied with nitrogen fertilizer. The grain yield and yield components were all elevated remarkably by applying different rate and type of fertilizer; four level of N (0, 23, 46, 69, 92) three levels of P (0, 10, 20), and three level of K (0, 10, 20) in addition the last three treatment foliar application 45 days after planting and comparing with control (absolute zero) treatment. There was significant difference in grain yield and yield components of Madda walabu (bread wheat) among the treatments. The results showed in addition to significant difference among the treatments, high yield response recorded under 46N-20P-0K-0S kg ha-1 (5, 3 t ha-1) and followed by 69N-20P-0K-0Skg ha-1 (4.5 t ha-1) the lower yield response was under control treatment (2.3. t ha-1). In conclusion, fertilizer rate containing nutrient combination of rate of 46 N 20 P (kg ha-1) had brought the higher grain yield and showed efficient use of fertilizer combination. The result indicted that the optimum fertilizer applications for bread wheat 46 N 20 P (kg ha-1) were brought maximum yield for selka site of sinana district.

Abstract: There is a particular situation in the financial market that the natural state space is known and the probability distribution is unknown which called Knight Uncertainty. The strict assumption of the traditional pricing model in the past was challenged. The influence of Knight Uncertainty on the pricing of financial derivatives white sugar options is discussed. The price of white sugar option in China is empirical analyzed by using the option pricing model under Knight Uncertain environment. The pricing interval of the option is obtained by using the net uncertainty coefficient. At the same time, it is found that the parameters of Knight Uncertainty directly affect the accuracy of pricing through comparison with real price. It can fit well with the real price if taking the appropriate size of the net uncertainty metric parameter. The research results can provide theoretical support for investors and regulators.
