Abstract
This study was conducted at Sitio Bacsayan, Poblacion, San Gabriel, La Union from December 17, 2004 to February 15, 2005 to determine the effect of optimal irrigation to corn yield reduction considering the following parameters: height of plants at harvesting time, weekly growth rate of plants, number of corn ear produce per treatment and weight of young corn per treatment. The Randomized Block Design (RCBD) with three treatments and three blocks was used.
The treatments were as follows:
T₁ - Irrigation occurred from seeding stage to silking stage
T₂ - No irrigation at tasseling to silking stage
T₃ - No irrigation at late whorl stage
T₄ - No irrigation from seeding to mid-whorl stage
T₅ - Irrigation occurred only from seeding to mid-whorl stage
T₆ - Irrigation occurred at late-whorl stage
T₇ - Irrigation occurred at tasseling to silking stage only
T₈ - No irrigation occurred (traditional method)
Analysis of Variance (ANOVA) was used to determine the effects of optimal irrigation to corn yield reduction. Least Significance Difference was used for further test of significance.
The optimal irrigation pattern for corn were evaluated. The results indicate that corn plants under 1.0 E.T. did not significantly influence the weekly growth rate of plant, height at harvest time, size of young corn in terms of the diameter and weight of corn. Significantly increased in the number of young corn and size in terms of the length. Under 1.5 E.T., the results demonstrated insignificant in the height of plants at maturity, weekly growth rate, number of young corn ear, size of young corn (dia, length) and weight of young corn ear.
