Abstract The suitability of the Dirma River Basin in Ethiopia for surface irrigation potential development and identification potentially irrigable sites were subject present study. river basin area was evaluated based on slope, soil water resource availability using ArcGIS 10.1. Potentially suitable potato tomato crops. reference crop evapotranspiration, effective rainfall, net gross requirement estimated CROPWAT software. results model developed indicated that about 68.3% total falls...

In the present study, Meteorological Drought (MD) has been analyzed using India Department (IMD) criteria, and Standardized Precipitation Index (PIStandard) in foothills of central Himalayan region Uttarakhand State, India. Rainfall time series at two weather stations, namely Pantnagar Dehradun stations were selected. For evaluation PIStandard method, moving sums rainfall data arranged monthly scales 1, 3, 6, 12, 24 months. The after sequencing it a for testing different statistical...

Irrigation water management practices are the main strategies to improve productivity. This research work was focused study performance of alternate and paired row furrow irrigation systems at three levels (100%, 75%, 50% crop evapotranspiration) using different productivity indicators for onion crops. The experiment had six treatments replicated times evaluate analysis variance in SAS software. Water like use efficiency, field expense efficiency were determined through bulb yield which used...

Utilizing empirical advance and infiltration functions, relationships for surface subsurface storage shape factors have been obtained. The as expressed by these found to be a function of time well characteristics soil. Incorporating relationships, continuity equation has written water in irrigation. compares with field data other workers.

The vulnerability of soil toward erosion might be reduced by having a good vegetative cover over the surface, slope improvement, and improving properties so that it is not easily detached transported. However, establishment proper long process because takes time for seeds to germinate attain maturity. As an alternative approach, if resistance was increased increasing shear strength against erosive forces offered eroding agents, system would become capable withstanding detachment its...

In this study, the operational and design performance of main canal (MC) was assessed to determine carrying capacity water delivery during peak irrigation requirement using selected indicators. The indicators used were ratio, relative changes in level (RCWL) ratio. study carried by collecting data comprising flow discharges at locations MC conveyance system. climate crop growth parameters (QR). estimated for entire commands East-bank 5.68 m3s−1 February. results revealed that designed...

Drip irrigation is a highly efficient technology widely adopted in row crop agriculture, particularly regions with limited freshwater resources.This controlled distribution minimizes the surface flow of water and percolation, enhancing insectpest management salinity control.This study was carried out College Agriculture Sciences Engineering, IFTM University, Moradabad, Uttar Pradesh (India).The treatments embraced different pairs five drip levels T1 (1 hr one-day intervals), T2 (2 hrs two...

This study was conducted in the College of Agriculture Sciences and Engineering, IFTM University, Moradabad, Uttar Pradesh (India). Drip irrigation, a relatively new technology world, has increased vegetable crops. In India, eggplant, also known as brinjal, is cultivated across approximately 0.72 million hectares land. The included various drip irrigation treatments: T1 (1 hour every day), T2 (2 hours two days), T3 (3 three T4 (4 four T5 (Control with furrow irrigation). findings showed that...

The study was carried out to on identification of performance gaps for improvement center pivot sprinkler system in the Tigray region Northwest Ethiopia. objective identify irrigation and suggest remedial measures system. methods used gap Identification were observation, Interview, measurement, using design document. Center revealed that Excess runoff due leaky boots higher application depth, absence regular checkup emitting devices, improper scheduling dominant Making functional an...

Irrigation practice evaluation of center pivot sprinkler irrigation system at Hiwot Agricultural Mechanization farm, North/west Ethiopia was conducted. The aim the study evaluating existing in terms scheduling. Measuring flow rate machines for and Crop water requirement based scheduling used to evaluate system. highest value crop location m6, m7 m12 5.24 mm/day September mid-stage m4 m8 October equal 4.99 mm/day. Whereas, lowest 2.52 July initial stage which august 2.08 actual varies from...

Early blight of potato caused by Alternaria alternata is one the major diseases causing considerable yield loss. Efficacy bio-agents was studied and revealed all four Trichoderma species significantly reduced mycelial growth pathogen over control dual culture method. Significantly maximum inhibition obtained with T. viride (57.08%) followed azospirillum (50.00%), harzianum (43.26%) virens (37.08%) after 48 hours incubation. In present study, observed more inhibitory against A. alternata....

The movement of sediment particles is governed by the relative magnitude acting drag and resistance offered particle. force that acts on a particle depends flow parameters as well surface area exposed to flow. Similarly, its weight in contact with stream bed. In case spherical particles, orientation does not play an important role, while non-spherical how orients itself vital role. Therefore, which real situation, velocity will depend their orientation. Numerous studies have been conducted...
