Factors influencing food insecurity among small farmers in Nigeria
This study estimates a food insecurity index and examines the factors that influence food insecurity among small farmers in Nigeria. Data for the study were collected from 400 farming households in Osun area of the southwestern Nigeria. Descriptive statistics, a cost of calorie function (COC) and a Tobit regression model were used to analyze the data. A regression model made up of 15 regressors was specified. Eleven of...

Improved efficiency of microspore culture of Brassica campestris ssp. pekinensis (Chinese cabbage)
We selected two cultivars of Brassica campestris ssp. pekinensis (Chinese cabbage), ‘Futian 50’ and ‘Changkuai,’ to investigate the factors that influence microspore embryogenesis and plantlet regeneration. We have also discussed some protocols for the induction culture of microspore-derived embryos and for rooting and transplantation of microspore-derived plantlets. We obtained the following...

Assessment of soil properties and crop yield under agroforestry in the traditional farming system
The rate at which soil ecosystem is being degraded in crop production systems in the tropics is alarming. This study therefore attempts to assess the physico-chemical properties of soil and crop yield under agroforestry in the traditional farming systems. This was a researcher-designed, farmer-managed participatory experiment. Two farming systems (cashew/maize intercropping and sole maize cropping) were used. The two...

Effects of organic amendments and fungicides on the survival of collar rot fungus of soybean incited by Sclerotium rolfsii
Soil-borne plant pathogenic fungi cause heavy crop losses all over the world. With variable climate from region to region, among tropical and subtropical land crops, soybean [Glycine max (L.) Merill]. is an important oil seed crop, providing vegetable oil as human food. Results revealed that alone fungicidal seed treatment (main), alone soil application of organic amendments (sub) and their interactions significantly...

Effects of nitrogen rates and application time on popcorn
Among the various limiting factors in the production of Brazilian popcorn, paucity of information on cultural practices is highlighted, with emphasis on the management of fertilizer, especially nitrogen (N) topdressing. This mineral nutrient is of great importance in several agronomic characteristics of corn plants, mainly components of production. The aim of this study is to evaluate the effects of N management on...
