Abstract

A field experiment was conducted to evaluate the effect of irrigation regimes on yield and water use efficiency of maize crop (Zea Mays L.; SAMMAZ 29) under different irrigation scheduling. Randomized Complete Block Design (RCBD) was used and the experiment consisted of three levels of irrigation water application depth of 100%, 75% and 50% replacement of Total Available Water Capacity (TAWC) and three irrigation intervals of 7, 10 and 13 days replicated three times. Irrigation water was applied into each of 0.75 m × 90 m furrow using siphon tube of 7.5 cm diameter and 200 cm length. The results showed that the highest average irrigation water use efficiency was at I10D75% with 0.71 kg/m3 while the least was at I13D50% with 0.41 kg/m3. The highest average crop water use efficiency (CWUE) was at I10D75% with 0.79 kg/m3 while the least was at I13D75% with 0.56 kg/m3. The highest average maize yield was at I7D100% with 3580 kg/ha while the least was at I13D50% with 1200 kg/ha. The study established that irrigation after every 10 days interval with 75% replacement of TAWC using furrow irrigation of 90 m lengths produced the highest crop water use efficiency, thus saving about 48.3% of irrigation water (amounting to 329 mm) with reference to control (I7D100%) which causes a yield reduction of about 19% (amounting to 680 kg/ha). This efficient water usage saved cost and also helps to address the problem of high water table of the study area.

Highlights

Proper irrigation water management plays a vital role in 2000SynEE-W-STR and it was released in the year 2009

Summary

Introduction

Proper irrigation water management plays a vital role in 2000SynEE-W-STR and it was released in the year 2009. Irrigation scheduling is the decision of when and how much a medium maturity grain crop requires between 500 and 800 water to apply to a field in order to maximize profit (Tariq and mm of water depending on climate (FAO, 2013). Limiting factor; rather the abundance of water is a problem It minimizes water-logging problems by reducing the drainage which results in over irrigation because of abundance water requirements and control root zone salinity problems through (Sani et al, 2008). Farmers apply on average, twice the consumptive use of crops (Sani et al, 2008).
