Effect of irrigation regimes on the quality, growth and productivity of mango [electronic resource]

The situation of water shortage in arid and semiarid regions is getting
worse due to the unexpected climatic changes. continuous population
growth and increasing consumption of fresh water in the agricultural
sector. The aim of study was to evaluate the impact of irrigation regimes
on quality. tree growth, and mango yield, under semi-arid climate.
Therefore, these experiments for mango trees (Eiwas) were carried out
during 2013 and 2014 in soil of sandy soil under different irrigation
regimes. The drip irrigation system was used The mango tress was
exposed to four water regimes through two years (T1= 100% of available
water as a control, T2 = 85% of T1. T3 = 75% of T1and T4 = 60 % of
field T1). Manure was added to all treatments with the same percentage, while compost in addition to manure was added the last three of them. The results showed that, the T2 treatment proved to be the most appropriate, since it allowed the trees to reach the highest yield (6360.9 Kg/ fed) and the best water-use efficiency (1.13 kg/m3). When, the T4 proved to be the lowest values, since it allowed the trees to reach the lowest yield (2166.6 Kg/fed) and the lowest water-use efficiency (0.55 kg/m3). There were good relationships between water requirements with yield. volume. total acidity and leaf area under four water regimes (R2 equal to 0.72, 0.81. 0.86 and 0.99). respectively.
