“…The improved vegetative growth with above mentioned superior genotypes under both furrow irrigations (0.8 IW/CPE) ratio and drip irrigation (1.0 ETc) might be due to proper balance of air and moisture in crop root zone, which might have created favorable conditions for genetically superior genotypes to enhance nutrients uptake, photosynthesis and metabolites translocation which ultimately accelerated the rate of vegetative growth. These results are in harmony with findings of Adamu et al (2014) and Ben et al (2019).…”

“…Though furrow irrigation has received sufficient PERFORMANCE OF MAIZE GENOTYPES UNDER DRIP IRRIGATION water, it has recorded lower water productivity due to ineffective use of water and inferior genetic potential of the genotype. These results are in agreement with Ali and Mohammed (2015) and Ben et al (2019).…”

A field experiment was conducted during summer 2018 and 2019 to study the performance of maize (Zea mays L.) genotypes under drip and furrow irrigation regimes at the Main Agriculture Research Station, University of Agricultural Sciences, Dharwad, Karnataka. The experiment was laid out in strip plot design with 3 replications. Treatments included 4 irrigation levels (drip irrigation at 0.6 ETc, 0.8 ETc and 1.0 ETc and furrow irrigation at 0.8 IW/CPE ratio) and 4 maize genotypes. The data indicated that, furrow irrigation at 0.8 IW/CPE ratio and drip irrigation at 1.0 ETc recorded significantly higher and on par growth and yield parameters, grain yield (75.8 q/ha and 71.4 q/ha, respectively) and economic returns. Drip irrigation at 1.0 ETc consumed 28.6% less water but recorded significantly higher water productivity over furrow irrigation. Among the genotypes, NK-6240 found superior over rest of the genotypes. The combination of furrow irrigation with NK-6240 recorded significantly higher growth and yield attributes as well as grain yield and economics over rest of the combinations. However, this treatment remained statistically non-significant with drip irrigation at 1.0 ETc with NK-6240 and furrow irrigation with CP-818.

“…Scientific research advancing the genetic improvement and biotechnology of maize crops has contributed to increasing their adaptation to water shortage scenarios (Langner et al, 2019). Maximum technical efficiency of irrigation depths has increased grain yield from 9.9 to 41% (Ben et al, 2019).…”

This study aimed to verify the incidence of Fusarium spp. in commercial maize hybrids and irrigation management strategies utilizing center pivot systems. The experiment was carried out during the second season in a randomized block design with a split-plot arrangement with five maize hybrids (2B810, MG580, AS1633, DKB290, and AG8544). The plots were irrigated with five frequencies (1, 2, 3, 4, and 5 days) in one experiment, and five water depths (at 25, 50, 75, 100, and 125% of crop evapotranspiration) in another experiment. Plant height, ear insertion height, moisture at harvest time, yield, and incidence of stalk rot were evaluated. Neither irrigation frequency nor irrigation depth influenced the incidence of disease. The one-day irrigation frequency provided the highest yield for maize hybrids. Hybrid 2B810 showed the highest yield and the lowest incidence of the disease.

The costs involved in the implementation and operation of irrigation systems are of paramount importance for the economic planning of irrigated agriculture. Therefore, the objective of this work was to determine the implantation, fixed and annual variables costs, and the occurrence of economies of scale for a fixed conventional sprinkler irrigation system for different area sizes and slope in the impulsion line. Thus, irrigation projects were developed for areas of 1, 3, 5, 10, 15, 20 and 25 ha and slopes in the pumping pipe of 7 and 15%. Also, this work evaluated the implementation, annual fixed and variable costs and their components and the occurrence of economy of scale. The implementation, fixed and variable costs increased as the size of the area increased, but for the fixed and implementation costs, an increase was observed due to the exponential cost of the pipes and their greater participation in the total cost and the variable cost was because the maintenance follows the implementation cost. Therefore, the cost with the pipelines has greater participation in the implementation of the system. The cost of implementation and the total fixed and variable costs raised with the increases in the size of the irrigated area. The variable cost of energy is constant as area size is increased and the raise is by approximately 5.2%, as the slope increases from 7 to 15%. The increasing in the size of the irrigated area provides diseconomies of scale.
