An infiltration model development and evaluation for pitcher irrigation system

Abstract

Infiltration models are based on quantitative relationships among variables that are developed analytically, or from a spectrum of infiltration data that could be fitted into the equation. An attempt was made to begin the development of a mathematical (infiltration)m model using the assumptions of Hillel and Gardner (1969; 1970), incorporating the assumptions of Green and Ampt (1911) and Philip (1957a;1957c). The model developed in this study used Pitcher (pot) and soil properties, as well as the time of infiltration as inputs. The model proved to be capable of predicting infiltration better than the pitcher infiltration equation advanced by Clifthill (1983), which did not consider the properties of the soil beneath the pitcher. The developed pitcher model gave a better prediction of infiltration, especially with pitchers fired at low temperatures (<650°C) and, which invariably had higher seepage rates than in pitchers fired at high temperatures (>850°C).

Clay Pot Irrigation- A Review Study

“…Researcher described the salt tolerance of five cultivars of Capsicum annuum L and the variety NMCA 10652 had the highest survival percentage at 100% in the 4.1 dS m-1 treatment, followed by 'Early Jalapeno', 'Nu-Mex Sweet', Pimienta De Chiera', 'Santa Fe Grande', 'Golden Treasure', and 'Nu-Mex Joe E [21]. Scientist found that the highest dry chili yields of 8.12 and 20.78 q ha-1 were obtained from nonsaline canal water followed by two applications of non-saline water alternating with one saline water with 7.30 and 20.38 q ha-1 respectively [22]. Saline (well) water irrigated plants yielded 3.99 and 11.72 q ha-1 respectively, which represented yield reductions of 50.8% and 43.6%, respectively as compared with nonsaline.…”

Pitcher Irrigation: Some Theoretical and Practical Aspects

“…A number of recent studies (Qiaosheng et al, ; Siyal et al, ; Siyal and Skaggs, ; Saleh and Setiawan, ; Usman et al, ; Al‐Mohammed, ) have examined patterns of soil wetting by buried pots or porous pipes to find the most adequate position and distribution of these irrigation emitters. On the other hand, Abu‐Zreig et al .…”
