Description
The objective of this study is to determine the optimal irrigation dose of tomato through a test by varying the doses by the restrictive method of irrigation, 100% Db, 90% Db and 80% Db respectively for D1; D2 and D3. It is conducted in microirrigation at the Falki / Mirriah / Zinder vegetable site in Niger. The estimation of the dose is based on the knowledge of the ETo, the SEM knowing the crop coefficients and the useful reserve knowing the soil data. These calculations are done by the FAO CROPWAT 8.0 software. Irrigation water intakes during the experiment were 1517.45; 1365.73 and 1213.99 mm respectively for D1; D2 and D3. During this test on the device Full Block Reassonated (BCR 3x3); observations and measurements are made on the parameters taken into account (HMP; NMF/P; PMF and the yield per unit plot and per hectare). The statistical analysis of yield showed a significant effect for the treatments and describes the influence of the variation of the irrigation doses as such: the yield given by the D2 (46.69 t/ha) is superior compared to the D1 (36.04 t/ha) and D3 (37.80 t/ha). This variation shows that the optimal dose under local climatic conditions is D2 which gives the best yield and is water efficient with the use of 90% of the calculated gross dose.
