Book Description
Maize (Zea mays L.) one of the most important cereal crop in Ethiopia, but growth performance and yield is very low due to in appropriate sowing depth. A green house experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine during 2014/15 cropping season to investigate the effects different sowing depth on germination and growth performance of maize. The experiment was consisted of five level of sowing depth (2cm, 4cm, 6cm, 8cm and 10cm) in randomized complete design with three replications. The data were collected based on seed germination which determined by germination percentage and germination date with their growth performance. The results showed that sowing at depth of 6cm produced the tallest plant, highest number of leaves per plant, leaf length, leaf fresh weight and dry weight. The 10cm depth showed late in germination date and has poor performance as compared to other sowing depth when looked over the result. However, the results of the experiment were only growth parameters and did not include yield. So, similar research is needed to be conducted until final yielding of maize for better recommendation.

Book Description
This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

Book Description
An analysis of growth of maize in relation to water in the soil-plant system was conducted in the field at Davis, California. The time course of root and aerial growth, and water uptake was investigated under conditions of a mild prolonged water stress, with emphasis of defining the soil and crop water status, photosynthesis and the generation of the yield and yield components also were studied. Hybrid maize was grown in deep alluvial soil with high mositure holding capacity. Three irrigation treatment were: a) Weekly 5-cm irrigation starting 21 days after planting (I treatment); b) No irrigation (NI treatment); c) Weekly 5-cm irrigation starting 55 days after planting (155 treatment). Shoot growth. NI treatment, compared to I treatment, reduced crop height 6.5% leaf area 11% although leaf y (water potential) generally was only 2 bars lower at midday during vegetative growth. Diunally, leaf elongation rate (in both treatment) was unespectedly fastest in early afternoon when leaf y was near the daily minimum. Leaf (solute potential) changes lagged behind y so high occurred at near minimum y values, and daytime elongation rates (presumably when temperature was not limiting) correlated with - leaf changes were associated with those of oraganic solutes; soluble leaf carbohydrates changes accounted for 40% of fluctuations. Consistently lower leaf elongation rates in NI treatment could m-not be explained by differences alone, however. Root growth water absorption. Water uptake at various soil depth and times (...).

Book Description
Stresses create barriers in normal growth and developmental processes of plants. Plant life cycle is distorted variably depending upon severity of stress, type of stress and growth stage of plant. Among stresses drought is most severe regarding adverse effects to the agricultural crop productivity at Global level. Among cereals, maize is very important cereal due to multiple utilization for versatile purposes. Drought also affects the maize as it does with other crops so, there is dire need to recognize the effects of drought on maize in detail. This book is typically focusing on interference by drought in maize life cycle. Determination of possible effects on a plant enables the researcher to explore the resources to ameliorate the adverse effects of stress. Furthermore, recognition of plant traits to exploit in breeding, selection and screening of germplasm is also very critical stage in-order to identify suitable traits. This book also include the traits to be used as selection criteria for improvement against drought stress in maize.

Book Description
Water stress is one of the major abiotic stress factors thatcan effect on maize(Zea mays L.)plant growth. This study was focused on the effect of water stress on maize growth under greenhouse condition in Perlis, Malaysia. The experiment was conducted in the greenhouse at campus Jejawi Universiti Malaysia Perlis over the duration of 10 weeks from 7 January 2016 to 11 March 2017. The maize was grown under four different level of water stress which is Control (no stress), Treatment 1 (low), Treatment 2 (medium), and Treatment 3(severe). The maize plant was irrigated daily according to their different percentage of total available water (TAW). Control is 100% of TAW, Treatment 1 is 75% of TAW, Treatment 2 is 50% of TAW and Treatment 3 is25% of TAW. The main objective in this study is to determine the effect of water stress on maize growth. In control and different water stress condition, the morphological of maize growth also was measured such as height of maize plant, diameter of stem, number of leaves and area of leaves. At the end of this experiment, the responses of growth parameters to the different condition water stress wereanalyze using ANOVA.The results obtained indicated that for treatment in no stress condition is better compared to others treatment. The result shows the mean height of plant for no stress, mild, medium and severe stress is 141.33 cm, 120.00 cm, 89.33cm and 56.67 cm respectively. Besides, diameter of stem for each treatment also shows the no stress condition is better. It is proved by the mean diameter of stem for no stress, mild, medium and sever stress is 2.17 cm, 2.13 cm, 2.00 cm, and 1.67 cm respectively. Overall, the growth of maize shows more effective for maize grown under no stress and mild stress condition.
