Poor soil fertility is important constraints that limited crop production in Ethiopia. The Masha district was highly prone to phosphorus fixation with ions like Aluminum ion since soil of the area is prone to acidity. This experiment was therefore conducted to investigate the effect of of phosphorus fertilizer with agricultural lime, coffee husk ash and coffee husk charcoal on yield of faba bean and agronomic efficiency of the fertilizer on acidic soils of Masha district. Field experiment involving two rates of phosphorus (23 and 46 kg P2O5/ha) and the three soil amendments was in randomized complete block design with three replication. The result indicated that significantly high grain yield was obtained from integrated application of 46 kg P2O5/ha with the agricultural lime, coffee husk ash and coffee husk charcoal with the observed values of 2265, 1953 and 1943 kg/ha, respectively. Agronomic efficiency significantly great values were obtained from treated with the agricultural lime+23 kg P2O5/ha, agricultural lime+46 kg P2O5/ha, coffee husk ash+23 kg P2O5/ha and coffee husk charcoal+23 kg P2O5/ha with the observed values of 14.86, 14.60 and 10.07, respectively. It can be concluded that 46 kg P2O5 with 2.5 ton agricultural lime, 7.5 ton coffee husk ash or 7.5 ton coffee husk charcoal per hectare on acid soils for high yield and yield components on faba bean at Masha district. When 23 kg P2O5/ha was integrated with the soil amendments, relatively high agronomic efficiency was observed.

In this study, it is aimed to establish quality critical points in order to determine the quality of feeds prepared in compound feed factories before production. For this purpose, quality control points should be established and continuously monitored in compound feed production. With our study, the quality of the raw materials we use in the production of compound feed (feed nutrient contents), and then determined the important technological changes in feed mill; control points were established in mill, mixer, molasses mixer, conditioning, pellet press inlet, pellet press outlet, cooler and packaging sections. Four different mixed feeds (quail, laying hens, dairy cow, beef cattle feed) were sampled from these regions. The study was carried out in a commercial feed factory. Firstly, rations were prepared with the formulation program on the computer of these compound feeds. Then, samples were taken from the determined points and nutrient contents (dry matter, crude protein, crude oil, crude cellulose, crude ash, starch, sugar, metabolic energy value) were compared with both chemical and NIRS method. According to the data obtained; In the samples taken under the mill, both chemical and NIRS methods were used and the results did not reflect the formulation values. According to the findings of the research, the results obtained from the samples taken from the sub-mixer bunker showed close values from the formulation values of the mixed feeds and it was concluded that it may be the most appropriate quality critical point.

Water deficit is one of the main limiting factors affecting plant growth. Selection in water-limited environments can result in populations or species with improved response to drought. Water deficit decreases yield and quality, therefore, it is important to identify genotypes that are tolerant to deficit irrigation conditions. In this study, the water-deficit tolerance of 59 pepper-inbred lines was determined. Experiments were conducted in a growth chamber and under field conditions (Şanlıurfa) with a control (100% full-irrigation) and water-deficit treatment (50% irrigation). Fruit weight, fruit length and number of fruits were recorded. Pepper lines 1900, 896 A-W, 74, 760, 1560-W, 912 A-W, 405-A, 953-W, 226, 1105-W and 441 were identified as the most tolerant to water deficit conditions. Present findings revealed that these pepper lines could be used to develop cultivars that have satisfactory yield under water deficit conditions.

Pulses in Pakistan is used in combination with cereals to balance the diet. Its area and production is decreasing for last many years. In the barren and partly arid regions, water shortage is the major component that restricts yield. Using of drought resistance plant is one of the best ways for good cultivation under drought condition. As the pulses have great nutritional and economical values and drought stress affect their morphological features. The legume yield is mostly cultured in rain fed region of the Punjab where they bear a slighter quantity of water situation resulting in low yield of bean. To overcome these problems it is necessary to get knowledge about the performance of different lines of different pulses crops under water stress conditions. That’s why in this paper the information about the previous literature has been discussed.

Cucurbita pepo spp. pepo has a unique ability to phytoextract Persistent Organic Pollutants (POPs) such as p,p’-DDE from the contaminated soil to plant compartments. Although the uptake mechanism of the POPs by the plants still remains unknown, p,p’-DDE has been accumulated in the plants grown in the contaminated fields, posing the environmental and human health risks. In this study, p,p’-DDE accumulation was investigated in the plants grown in contaminated soils amended with of 0%(control), 0.1%, 1%, and 10% of biochar produced from activated sludge under greenhouse conditions. The p,p’-DDE concentrations in soil and plant samples were measured by an Agilent 7890A GC with μ-ECD detector. The p,p’-DDE concentrations in roots and shoots of the plants were decreased 94% and 87% compared to the control set, respectively by 10 % biochar amendments which are significantly different from the other sets. On the other hand, p,p’-DDE concentrations in roots were not affected by biochar amendments and measured between 7 ng/g to 8 ng/g for the all sets. Biochar from activated sludge will help sustainable usage of the sludge as soil amendments to the contaminated fields, highlighting the importance of some future studies on the products from waste materials.
