Salinity is the dissolved salt content in soil or water and is a major issue in irrigated agriculture. Field experiments were conducted to study the soil moisture and soil salinity pattern at different locations for furrow-bed and furrow-ridge irrigated wheat crop. Results were compared to border irrigation. Wheat was sown on plot size of 55.5m X 7.31m having loam soil. Traditional flat sowing was accomplished with row to row distance of 23cm using seed drill and two rows of wheat planted manually on both 30 cm x 60 cm wide furrow-bed and 45cm wide furrow-ridge. Four irrigations...

Soil Conservation Service-Curve Number Methods
ISBN: 9783639259278 / Angielski / Miękka / 2010 / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Increase in demand of water with passage of time for irrigation and hydropower lead Pakistan to conserve its all water resources. Unfortunately the absence of long term runoff record makes it difficult to estimate the availability of water. Therefore for estimation of runoff certain other techniques are in use but the most common method in practice is SCS-CN method. SCS-CN technique shows the catchment response of precipitation in the form of runoff. Mishira and Singh modified its equation by introducing two more parameter and redefining one term and finally recommended modified...
