Quality changes of fresh noodles prepared from wheat cultivated with N-fertilization treatments, followed by γ-irradiation were investigated. The protein content of the KPS60 was the highest of all treated samples, and protein contents of wheat cultivated with N-fertilizer was increased. γ-Irradiation did not affect the protein contents of the samples. However, the water holding capacity and resistant starch contents was increased by irradiation. The dry gluten and wet gluten contents of samples were further increased by γ-irradiation. The pasting properties were influenced by γ-irradiation but not N-fertilization. The hardness of noodles made with irradiated wheat flour was decreased, but the degree of decrease was small compared with that of viscosity. The gumminess and chewiness of noodles made with irradiated flour having higher protein content and WG showed also higher score. Thus, treatment of wheat flour with N-fertilization and γ-irradiation may improve the quality of Korean-style noodles during storage.

The objective of this study was to investigate the effect of drip irrigation level on soil salinity and growth of broccoli (Brassica oleracea L. var. italica) at the 'Saemangeum Reclaimed Tidal Land' from April to June, 2015. Drip irrigation was conducted at 1.5, 3.0 and 6.0mm•day -1 level for reduction of resalinization in the plastic vinyl house using 10cm spacing drip irrigation tape. At harvesting stage, the average EC of surface soil was 10.9dS•m -1 for 1.5mm•day -1 , 11.5dS•m -1 for 3.0mm•day -1 and 5.1dS•m -1 for 6.0mm•day -1 and was significantly reduced by 52~56% in 6.0mm•day -1 treated plot compared to those in 1.5 and 3.0mm•day -1 plots. The fresh bud weights of 1.5, 3.0 and 6.0mm•day -1 treatment plots were 60.9, 129.1 and 371.3g•plant -1 , respectively. The estimated soil EC for 50% yield reduction was 7.6dS•m -1 and the desalinization depth by drip irrigation was 30~40cm in soil profile. The total amount of drip irrigation water was estimated to be 422mm and the daily drip irrigation level was 6.0mm•day -1 for the prevention of resalinization during the broccoli growing period at the 'Saemangeum Reclaimed Tidal Land'. Our results suggested that drip irrigation shows effectiveness on the lowering the soil salinity according to the drip irrigation quantity but it needs more research on this study because dynamics of salts in soil can vary with many factors such as soil physico-chemical properties and seasonal climate.

ABSTRACT. The Experiments were conducted by moderate season culture of each of early, medium and late maturing varieties which were considered to be of strong salt tolerance in low and high salty reclaimed areas (0.2% at the May). This study was carried out to investigate the proper nitrogen fertilizer level and seeding rates at reclaimed saline land in Korea. The proper seeding rates were 40 kg ha −1 in 0.2% saline land. The dry matter production of barnyard millet was possibly estimated by exponential functions of Y = 0.0098X 2 + 0.7030X + 2.6267. Effects of nitrogen rate on agronomic characteristics, forage yield, and chemical composition of barnyard millet to reclaimed tidal land are summarized as follows: The proper nitrogen fertilizer level was 200 kg ha −1 in 0.2% saline land. N was absorbed actively before the emergence of the barnyard millet but showed relative decrease thereafter. The early growth of the barnyard millet was inhibited, resulting in the favorable late growth, increased panicle weight and ratio of matured grain. These results suggest that barnyard millet is the most forage crops for cultivation on reclaimed tideland in view of the good emergence and forage production.
