To this end, it proposes a compaction operation able to reduce the volume and the water activity of the fish wastes, thus favouring their handling and reducing the economical costs associated to their transport and storage. To assess the viability of a waste compaction operation, the main operation factors governing the process were identified, and their influence upon the performance of a prototype at pre-industrial scale was investigated by a statistical approach. The main drawback associated to fish waste compaction is the generation of a variable amount of wastewaters, which cannot be directly discharged without a suitable depuration treatment. To this regard, the proposed wastewater treatment comprised two series filter cartridges, able to remove most of the fine solids followed by a membrane batch concentration unit able to produce a final permeate meeting the current environmental regulations. ····· 1036189185

Thousand hectares of agricultural land has been occupied by the increased population. That s why limited resources have to be utilized to the full extent to feed the increased stomachs. To increase the agricultural production soil characterization is a basic need. Soil characterization can be done in various soil parameters such as organic matter, nitrogen, phosphorus, potassium, pH etc. This study was carried out in Chitwan district where high intensity farming has been practiced for more than 20 years. The productivity of soil resources has declined due to soil fertility depletion, nutrient imbalance, decline in organic matter content and decline in physical and hydrological properties. It is therefore, increasing concern about soil resource inventory and its sustainability for the optimum use in the future. Geographical Information System (GIS) tool was used for generating distribution map of soil properties which provides information on resources which will be important to planners, decision makers and researchers. ····· 1036189168

The next most accurate approach would be one which integrates our understanding of the soil-plant-atmosphere continuum as mechanically as possible. The Soil Water Balance (SWB) model is a mechanistic, real-time, generic crop, soil water balance, irrigation scheduling model. SWB gives a detailed description of the soil-plant-atmosphere continuum, making use of weather, soil and crop management data. Traditional irrigation was practiced in Ethiopia since time immemorial. Despite this, water productivity in the sector remained low. At Godino, farmers use the same water amount and interval, regardless of crop species and growth stage. In an effort to improve this, two of the traditional irrigation scheduling methods was compared with two more scientific methods, using furrow irrigation. The growth performance and tuber yield of potato cv. Awash revealed that irrigation scheduling using a neutron probe (NP) significantly outperformed the traditional methods, followed by SWB model irrigation calendar. Since NP involves high cost and skills to use, SWB is preferred. ····· 1036189148

Intercropping pattern 2:4 (H) gave the highest seed yield/acre as compared with those of normal population of 2:4 (N) and other patterns. Soybean variety (Giza 22) had higher values for all studied soybean parameters than Giza 111 variety. All studied parameters of intercropped soybean were increased by doubling distance between hills of maize plants from 30 to 60 cm under intercropping patterns. Leaf area and yield/plant of intercropped maize were higher than those of solid maize under the same density of maize in the ridges. Intercropping pattern 2:2 (N) gave the highest grain yield/acre as compared with the other intercropping patterns. Wider distance between hills of maize plants (60 cm apart) gave higher values for all studied maize characters. Increasing soybean plant densities under intercropping patterns (2:2 `H` and 2:4 `H`) caused significant increments in soybean yield/acre and land equivalent ratio without significant reduction in maize yield/acre.
