    <p>Irrigation is essential for crop cultivation in arid and semi-arid areas with limited rainfall and water resources. Efficient and effective use of water resources is required and saving irrigation water is important. Djibouti is a very dry region with annual rainfall of about 150 mm and an average annual temperature of 28.6°C. Due to such meteorological conditions, water resources depend mostly on groundwater, and this makes water extremely scarce. Therefore, water saving in agricultural sector is indispensable. This study aims at promoting effective and efficient use of irrigation water in Djibouti. The appropriate irrigation water amounts for tomato cultivation were estimated using CROPWAT provided by FAO and observed meteorological data at Ali Farren farm in Djibouti. The conditions required for calculating the amounts of irrigation water were medium loam soil based on the laboratory results of soil particle size test, and the tomato cultivation period from October to March according to the local farmers. The result showed that the average monthly reference evapotranspiration was 5.7 mm/day annually. Reference Evapotranspiration was maximum in July and August with 8.4 mm/day and minimum in December with 4.6 mm/day. The amount of irrigation water from October to March was about 476 mm which corresponds to the local tomato cultivation period.</p>

  • Long-term cultivation test of green pak choi (Brassica rapa var. chinensis) for reduction of phosphorus fertilizer application in greenhouse soil with high phosphorus accumulation Reviewed

    Authorship:Lead author   Language:Japanese   Publishing type:Research paper (scientific journal)  

    From 2001 to 2019, phosphorus fertilizer application was reduced over 100 harvests of pak choi (Brassica rapa var. chinensis) in greenhouse soil with high phosphorus accumulation.
    Available phosphate in the top soil declined over time to reach 152 P mg/100 g in 2011, but leveled off thereafter. Based on available phosphate in the top soil and phosphorus uptake in pak choi, we believe that phosphorus uptake of approximately 70% occurred from phosphorus accumulated in the soil. In the organic mixed fertilizer plots and garbage fertilizer plots, the efficiency of phosphorus fertilization was 48.8% and 60.0%, respectively. The cause of efficient phosphorus fertilization was considered to be mixing inorganic state phosphorus, such as a chemical fertilizer or palm husk combustion ash, into raw materials. There were no adverse effects on crop yields or growth even if phosphorus fertilizer was applied at a lower rate than phosphorus uptake after 100 harvests. This result contributes to removing the uneasiness of reducing phosphorus fertilizer.

  • Effects of betacyanin on salt tolerance in Swiss chard (<i>Beta vulgaris</i> var. <i>cicla</i>)

    <p>Swiss chard and spinach belong to the family Amaranthaceae. Swiss chard is rich in the pigment betacyanin, which has antioxidant properties. This study compared the salt tolerance of spinach and Swiss chard in terms of the suppression of Na penetration into the plants and the reduction of oxidative stress. The Na content of spinach increased in the roots and shoots with the increase in Na concentration of the treatment. The ability to inhibit Na penetration into the roots—examined on the basis of plasmalemma ATPase activity and glycine betaine content—was lower in spinach than in Swiss chard. However, Na treatment increased the plasmalemma ATPase activity and glycine betaine content in the shoots of both plants. In swiss chard, the pattern of Na content increase by Na treatment was markedly different from that in spinach. Within Na treatment concentrations that maintained plant growth, the Na content in the shoots increased with the increase in Na treatment concentration. However, no increase occurred at higher treatment concentrations. Meanwhile, the Na content in the roots did not change with the Na treatment concentration that maintained plant growth, but it increased rapidly above that concentration. Hydrogen peroxide content and superoxide dismutase (SOD) activity of both spinach and Swiss chard increased with Na treatment and increased markedly at growth-maintenance and growth-inhibitory Na concentrations, respectively. The catalase activity of spinach was substantially increased with Na treatment at all tested concentrations, while that of Swiss chard increased only at growth-inhibitory Na concentrations. Betacyanin content did not change regardless of Na treatment and treatment concentration, and a constant amount was maintained in the shoots.</p><p>Thus, salt tolerance was higher in betacyanin-containing Swiss chard than in spinach. The amount and mode of elimination and distribution of excess Na penetrating into the plants differed between both species. The findings suggested that betacyanin contributes to reducing oxidative stress at least at Na concentrations lower than the growth-inhibitory concentration, resulting in increased salt tolerance of Swiss chard. Because the betacyanin content did not change with Na treatment, the antioxidant levels might not be affected in Swiss chard grown under high-salt conditions.</p>
