In this study, economic analysis of five desalination technologies for saline agricultural land was carried out. The analysis was comprehensively evaluated by calculating changes in crop production and benefit/cost (B/C) ratio. The analysis of crop production was in the order of tomato > cucumber > a (musk) melon > watermelon > cabbage, and economical efficiency for desalination technology was in the order of soil exchange > soil addition > electrokinetics > under-drainage > subsoil reversal. In cost benefit analysis, B/C ratio was in the order of under-drainage > soil exchange > electrokinetics > soil addition > subsoil reversal, and all desalination technologies used in this study have the ratio higher than 1, which means economical efficiency was high. Based on the net production considering B/C ratio, the general economic analysis was exactly order from that of crop production analysis. As a result, economical efficiency of soil exchange was highest, and economical efficiency of soil addition and electrokinetic was relatively higher than others.

In this study, cost analysis of electrokinetic (EK) restoration process for desalination of saline agricultural land was performed for field application based on a pilot scale field application. For reasonable cost analysis, EK process was classified into three major parts: system design, installation and operation. Cost of system installation consists of materials and installation for electrode/electric wire, power supply and data monitoring, drainage system, etc. Operation cost was calculated based on electrical consumption and water charges for EK process. Total cost for EK process was 2,943,013 won for $1000m^2$ in greenhouse area. Cost for system installation was 2,553,786 won, that is, 87% of total cost, while cost for system operation was 389,229 won, that is, 13% of total cost.

Agroforestry in terms of intercropping cow pea as summer forage with Grewia tenax was undertaken under sub -irrigation system in two consecutive seasons of 2017 and 2018 in saline soil of Khartoum State of Sudan. The aims were to find out suitable agro forestry system for saline soils as well as to investigate effect of tree spacing on field summer forage crop under semi -irrigation system. Therefore G. tenax trees that spaced at 4×4 m were used as main factor versus cow pea crop that incorporated at 25×50 cm intervals by using completely randomized block design with 3 replications. Trees and crop parameters were determined in terms of plant growth and yield. In addition to land equivalent ratio and soil chemical and physical properties at different layers were determined. The results revealed that, soil parameters in terms of CaCo₃, SAR, ESP, pH paste and EC ds/m were increased with increasing soil depths. Meanwhile tree growth did not show any significant differences in the first season in 2017. Whereas in the second season in 2018 tree growth namely; tree height, tree collar and canopy diameters were higher under intercropping than in sole trees. Cow pea plant height recorded significant differences under sole crop in the first season in 2017. Unlike the forage fresh yield that was significant under the inter cropped plots. Tree fruit yield was higher under sole trees and land equivalent ratio was more advantageous under GS2 (1.5 m) which amounted to 4. Therefore it is possible to introduce this agroforestry system under saline soils to provide summer forage of highly nutritive value to feed animals and to increase farmers' income as far as to halt desertification and to sequester carbon.

Human-induced soil salinity is becoming a major threat to agriculture across the world. This salinisation occurs in both irrigated and rain-fed agricultural zones with the highest proportions in the arid and semi-arid environments. Livestock can play an important role in the management and rehabilitation of this land. There are a range of plants that grow in saline soils and these have been used as animal feed. In many situations, animal production has been poor as a result of low edible biomass production, low nutritive value, depressed appetite, or a reduction in efficiency of energy use. Feeding systems are proposed that maximise the feeding value of plants growing on saline land and integrate their use with other feed resources available within mixed livestock and crop farming systems. Salt-tolerant pastures, particularly the chenopod shrubs, have moderate digestible energy and high crude protein. For this reason they represent a good supplement for poor quality pastures and crop residues. The use of salt-tolerant pasture systems not only provides feed for livestock but also may act as a bio-drain to lower saline water tables and improve the soil for growth of alternative less salt tolerant plants. In the longer term there are opportunities to identify and select more appropriate plants and animals for saline agriculture.

서남부 간척지에서 벼 담수표면산파재배시 토양 염분농도별 적정 파종량을 구명하고자 $2003{\sim}2004$년에 걸쳐 호남 농업 연구소 계화도출장소 시험포장인 문포통(세사양토)의 저영답(토양 염농도 0.1%)과 중염답(토양 염농도 0.3%)에서 서간벼를 공시하여 파종량별 입모수, 생육, 수량 및 백미 외관 품위 등을 검토한 결과를 요약하면 다음과 같다. 1. 입모수는 중염답보다 저염답에서 파종량이 증가할수록 많았다. 2. 간장과 수장은 중염답이 저염답보다 파종량이 증가할 수록 짧았으며, 도복은 토양염농도에 상관없이 파종량이 증가할수록 심했다. 3. 완전미 수량은 저염답에서는 파종량 5 kg/10a까지, 중염답에서는 파종량 7 kg/10a까지는 증가되었으나 그 이상의 파종량에 서는 수량이 증가하지 않았다. 4. 백미의 외관상 품위는 파종량이 증가할수록 저염답보다 중염답에서 완전미율이 낮았다. 5. 따라서 서남부 간척지에서 벼 담수표면산파재배시 입모, 벼 생육, 완전미 수량 및 백미의 외관상 품위 등을 고려할 때 적정 파종량은 저염답은 $5{\sim}7kg/10a$, 중염답은 $7{\sim}9kg/10a$이 적당할 것으로 생각된다.

서남부 간척지에서 고품질 쌀 생산을 위한 생태형별 적정 질소시비량을 구명하고자 2003년과 2004년에 호남농업연구소 계화도출장소 시험포장 문포통(세사양토, 토양 염농도 $0.1\%$)에서 삼천벼, 화성벼, 남평벼를 공시하여 질소시비량에 따른 벼 생육, 수량구성요소, 수량 및 품질 관련형질을 검토한 결과를 요약하면 다음과 같다. 1. 단위면적당 수수와 영화수는 질소시비량이 증가할수록 많았으나 등숙비율이 낮았으며 현미천립중도 가벼웠다. 2. 백미의 완전립비율은 질소시비량이 많을수록 낮아졌고, 단백질 함량은 질소시비량이 증가됨에 따라 다소 높아지는 경향이었으나 아밀로스함량은 질소시비량간에 별 차이가 없었다. 3. 완전미 수량은 삼천벼가 질소 12/10a수준까지, 화성벼와 남평벼는 11/10a 수준까지는 증수되었으나 그 이상의 질소시비량에서는 수량차이가 인정되지 않았다. 4. 따라서 서남부간척지에서 벼 기계이앙재배시 완전미 수량, 등숙비율 및 미질 등을 고려한 10a당 적정 질소시비량은 $11\~12$으로 판단된다.
