The soils of South western Nigeria are rapidly degrading due to nutrient mining, soil loss, inappropriate land use, low inherent soil fertility coupled with adverse effects of climate change. These have resulted to persistent low yields and farmers’ poverty. The current farming systems have failed to improve continuous decline in crop production. There is need for integrated approach that involves mineral fertilizer, organic resources, and improved crop varieties with sound agronomic practices if the region will be able to feed its population of over 35 million people. Integrated Soil Fertility Management (ISFM) is an all-encompassing resource management technique that embraces the use of good planting materials, with appropriate organic and/or inorganic fertilizer application or their integrated use. It also entails adapting the various combinations of the ISFM components to local conditions which by implication means site specific management. There is lack of coordinated information about the components of ISFM being used in SWN and most stakeholders have not appreciated the importance of integrated approach. This paper is therefore put forward to review the status of Integrated Soil Fertility Management in South western Nigeria in order to identify knowledge gap for sustainable crop production in the region.
This study contributes in existing literature on integrated soil fertility management for sustainable crop production in southwestern Nigeria. The study also harmonizes research findings about ISFM thereby making information available for researchers, policy makers, extension agents and other stakeholders about ISFM protocols. It aids in identifying knowledge gaps for intervention.

A study was conducted at University of Uyo Teaching and Research farm to evaluate the effect of different tillage practices on growth and yield of fluted pumpkin in an ultisol. The treatments were no till, flat, surface hoeing, raised bed, mounds and ridges. The parameters studied were establishment percentage, number of leaves per plant, vine length, leaf area, number of branches, and number of pods, length and circumference of pods as well as pod yield in tons per hectare. Data collected were subjected to analysis of variance and means were compared using least significant difference (LSD) at 5% probability level. There was no significant difference in the establishment count. However, significant differences occurred in all other parameters studied. Best results were obtained from the ridges and mounds over the other tillage practices. Ridges and mounds are therefore encouraged for increased production of fluted pumpkin.
This paper’s primary contribution is finding that tillage practices have
additional benefits in the growth and yield performance of crops
particularly fluted pumpkin and farmers should till their soils before
planting preferably using surface hoeing which is a less costly tillage
