Water Deficit is an important limiting factor for crop growth and production in some regions of the world. It elicits several morphological responses in crop plants. Most of these responses are adaptive mechanisms to withstand water deficit or drought and to ensure both survival and reproduction. Balanced and integrated use of nitrogen fertilizer and straw mulch may enhance the accumulation of soil organic matter, improves soil physical properties and increase crop yield. Hence, impact of deficit irrigation, nitrogen fertilizer and straw mulch on the vegetative growth of maize were examined in a green house. The objective is to determine measures which will enhance resistance to drought and increase maize growth with improved soil conservation. Twelve treatments were considered by varying irrigation, rice mulch, and nitrogen fertilizer. Results obtained based on statistical analysis reveal that: (i) Mulch reduces the amount of water needed for irrigation. (ii) Mulch significantly (P<0.05) affect plant height, leaf number, leaf area and shoot biomass. (iii) The interactions of fertilizer mulch and fertilizer water significantly affect shoot biomass. Further field studies are needed to extrapolate the findings to a wider range of seasonal and site conditions.
