หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Development of Water Allocation Strategy to Increase Water Use Efficiency of Irrigation Project) ผู้เขียน:ดร.วราวุธ วุฒิวณิชย์, รองศาสตราจารย์, ดร.เจษฎา แก้วกัลยา, รองศาสตราจารย์, Ponsatorn Sopaphun, Watchara Suidee, ประพันธ์ สพเสถียร สื่อสิ่งพิมพ์:pdf AbstractIn development of water allocation strategy to meet crop water requirement and to utilize rainfall effectively, a computerized water allocation scheduling and monitoring system named WASAM 2 was developed. Song Phi Nong irrigation project was selected as a case study. WASAM 2 was used for water allocation scheduling in Song Phi Nong project for 3 cultivation seasons of 1994 dry and wet seasons and 1995 dry season. The discharge at 5 key regulators which are the entrance to 5 water masters were monitored on daily basis. The actual delivery performance of the 3 studied seasons indicated that the actual measured discharge was about 20-30% higher than the recommended WASAM 2 discharge because Song Phi Nong project was the downstream project and had to take all the remaining water from the upstream Phanom Tuan project. It is recommended that the water allocation scheduling system of Song Phi Nong and Phanom Tuan projects will be combined into one system to increase the efficiency in water allocation. The average irrigation efficiency of Song Phi Nong was 37.6% in dry season and 28.5% in wet season. WASAM 2 increased the wet season efficiency by 3-5%. The irrigation efficiency in the dry season was on the average 7.7% higher than that in the wet season. Some water master has the efficiency up to 46.9% in dry season. The irrigation efficiency of the project is still low by two reasons : (1) being unable to completely control the discharge, and (2) high seepage loss in the canal system. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Soil Moisture Depletion at Different Growth Stages on Yield and Water Use Efficiency of Bread Wheat Grown in Semi Arid Conditions in Ethiopia) ผู้เขียน:Mahamed Badel Mahamed, ดร.เอ็จ สโรบล, ศาสตราจารย์, Tilahun Hordofa, ดร.สุดสายสิน แก้วเรือง, รองศาสตราจารย์, ดร.จินดารัฐ วีระวุฒิ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA field experiment was conducted at the Malkassa Agricultural Research Center (MARC) in Ethiopia, during the off season of 2009 from January to April. The purpose of the study was to evaluate the effect of soil moisture depletion at different growth stages on yield and water use efficiency of bread wheat (Triticum aestivum L.) variety “Hawi” grown under semi arid conditions. Three soil moisture depletion (SMD) levels and 4 growth stages of SMD were used as the main- and sub-plots, respectively, and were arranged as split plots in a randomized complete block design with 4 replications. Irrigation was applied when the soil moisture was depleted by 50% (D1; control), 60% (D2) and 75% (D3) of available soil water (ASW) at 4 growth stages: 1) vegetative (V), 2) heading (H), 3) flowering (F) and 4) grain filling (G). All the plots were irrigated to field capacity after planting. Soil samples were taken before and after each irrigation event for the first 3 wk after planting. Thereafter, irrigation frequency was established according to treatments. All the treatments were irrigated when 50% of ASW was depleted for the whole growing season, except for the growth stages where SMD treatments were imposed. The SMD levels significantly affected dry matter, grain yield (GY), water use efficiency (WUE) and thousand seed weight (TSW) of the “Hawi” bread wheat. The 50% SMD gave the highest GY, TSW, spike length, plant height and WUE at each growth stage. Increasing the SMD level significantly reduced the yield and yield components of the “Hawi” bread wheat. Grain yield reduction was 26.6 and 30.8% for D2 and D3, respectively, compared with D1. |
