Comparing Water Performance by Two Different Surface Irrigation Methods

Using Thermal Units for Crop Coefficient Estimation and Irrigation Scheduling Improves Yield and Water Productivity of Corn ( Zea mays L.)

“…Average annual precipitation is about 525 mm of which 80% occurs from June through yield of grain that ranged between 6 to 10 Mg ha -1 (Mojarro et al 2012). Following INIFAP recommendations, a fertilizer dose of 200-80-00 (N-P-K) was applied for both years.…”

Hydraulic Approach into Olden Agricultural Aqueducts at the Mexican Region of Zacatecas

“…Therefore, this work took into account some recent contributions on the subject, carried out in regions surrounding each estate farm in question. In that sense, the findings of España [36], Flore-López and Bautista-Capetillo [37], Bautista-Capetillo et al [38], Mojarro et al [39], Luna [40], De León and Robles [41], and Allen et al [42] have been a reference point to infer irrigation water management. Due to temporal differences between previous literature and conditions prevailing then, it is appropriate to consider inherent reservations; notwithstanding, computations and also determinations derived from alluded methodologies are sufficient for the ends pursued here.…”

“…On the other hand, 10-day irrigation intervals were considered throughout the phenological life of each crop and 10 h as characteristic irrigation time. It is pertinent to clarify that the above values are adopted in this work since they are characteristic of the region; in case of furrow dimensions, it is common for farmers to adopt them, while furrow irrigation efficiency and irrigation time are result of evaluations carried out in different plots [37][38][39][40]. From the above conditions, it was found that for wheat, with a sowing date at the beginning of April, around 200 hectares would have been cultivated; however, by establishing until the end of the same month, the area would reach 250 hectares (rainfall would allow a 17% reduction in crop irrigation dose, in its most critical stages of water needs).…”
