The objective of the present study is to show a compilation of information in tomato and hot and sweet pepper grown under plastic mulching, combined with drip irrigation or with microtunnels. Sweet pepper under mulching needs to be irrigated preferably when soil moisture decreases to 50 % if the purpose is to increase unit area yield to 18.05 t·ha -1 (39 %) as an average of four water application methods. When mulching and flood-irrigating sweet pepper, we suggest the application of all nitrogen fertilizer before placing the plastic on the field. The use of microtunnels in sweet pepper is an excellent way to repeal insects transmitting virosis. But adequate precautions should be taken; especially in tomato and peppers, which are sensitive to higher than optimum temperatures that may cause negative effects on crop growth and yield. This happened in the present study with sweet pepper. Tomato grown under mulching with drip irrigation had a yield increase of up to 26.7 t·ha -1 (39 %) and resulted in water savings of 1,800 m
