dc.description.abstractDeclining soil quality is emerging as an environmental and economic issue of global concern, because degraded soils are becoming prevalent due to intensive use and poor soil management. Declining soil productivity due to poor soil quality (particularly Carbon and Phosphorus deficiency and high bulk density) has been a major limiting factor to food production in Nigeria. Also, failure in establishing rainfall onset usually affects farmers negatively in the Northern Guinea Savanna Ecological Zone (NGSEZ) for proper planning of cropping activities. This call forPrediction of optimum rainfall so as to validate effective planting dates for high maize yield in the Northern Guinea Savanna zone, two consecutive years‟ field trials were conducted in 2016 and 2017 rainy seasons at the Institute for Agricultural Research (IAR) farm located at Samaru (latitude 11o1‟N and Longitude 7o3‟E) in the NGSEZ of Nigeria to study the effect ofcover crops and planting dateson maizeyield.using Randomized Complete Block Design (RCBD)in factorial arrangement with a combination of four planting dates and two cover crop Centrosema pascuorum and Cucurbitamaxima and no cover treatment replicated three times. Data generated was analyzed using SAS statistical package. The combined Result shows, the variation in the climatic data over the 35 years and during the two year of the experiment shows that maize can be grown over a wide range of climate with an optimum yield under adequate management. Planting dates statistically influenced grain yield in both first and second weeks of planting 4.08 and 4.01 tons/hectare similar to plots with no cover crop while the value for the last planting date (3.86) ton/hectare is similar to the plot with cover 3.78 Centrosema perscurum and 3.71Cucurbita maxima. physical soil properties such as (moisture and hydraulic conductivity) and climate (rainfall and temperature) are relevant to determine best planting date and optimum crop germination before the start of dry spell mostly experienced in the second to third week of June in these experiment.when subjected to Principal Component Analysis (PCA) to indicate their level of contribution to the maize yield. The soil quality assessment on the four planting dates evaluated in the study indicates that no cover and the two cover crop has same ranking while planting date one and two is better than third and fourth planting dates 1=best while 5=worst, CP=centrocema pascuroum, CM=cucubita maxima,NO=no cover, A= planting 1, B=planting date 2, C=planting date 3,D=planting date 4, SQ=soil quality.en_US
