ABSTRACT Pepper a perishable seasonal fruit, requires storage to extend its shelf-life. Appropriate postharvest handling and storage prolong longevity and preserve quality of Pepper Fruit (PF). However, there is dearth of information on its handling and storage in Southwest Nigeria. Therefore, the effects of postharvest handling methods and storage conditions on storability of PF were investigated. Two hundred Pepper Fruit Marketers (PFM) were randomly selected from pepper markets in Ibadan, ...
ABSTRACT Soil erosion is a major threat to sustainable agriculture in the humid tropics. Management practices adopted to control soil erosion and improve soil quality include mulching and the use of Vetiver Grass Strips (VGS). Integrating VGS with mulch could be more effective in controlling soil erosion than VGS or mulching alone. However, information on the effectiveness of combined utilisation of VGS and Vetiver Mulch (VM) in controlling soil erosion and improving crop yield is scanty. The...
ABSTRACT A field experiment was carried out at the Federal University of Technology Teaching and Research Farm, Owerri, to ascertain the responses of Cucumber (Cucumis sativus) to poultry manure and NPK fertilizers during the 2013 cropping season. The experiment was laid out as a 3x3 factorial in Randomized Complete Block Design replicated three times. The treatments were: poultry manure rates of 0, 5 and 10 ton/ha while N.P.K. rates were 0,200 and 400 kg/ha. Data on various growth and y...
Successful land management for tree crop production requires good knowledge of the soil variation and suitability for specific tree crops. Most of the traditional rubber growing areas in Nigeria have not been evaluated for their suitability and production potential. Characterisation and evaluation of the land for rubber production was therefore conducted. Soils of two rubber producing areas: Iyanomo, Edo State and Akwete, Abia State were characterised and evaluated using local, United St...
Stem borers are among the major biotic stresses limiting the grain yield of maize, an important cereal crop in Africa. Breeding for multiple resistance to maize stem borers has been reported to be a promising method of control. Understanding the genetic variability of crop populations will help in improving them for pest resistance. Thus, genetic variability for dual resistance to two stem borer species were determined in a white (DMR ESR-W) and a yellow (DMR ESR-Y) maize populations to ...
Use of single soil specific extractants to determine plant available phosphorus and exchangeable potassium for crops such as bell pepper, are costly, laborious and time wasting. Bell pepper, rich in antioxidants, requires phosphorus and potassium for high quality fruit yield. Mehlich-3 (M3), a multi-purpose extractant could extract phosphorus and potassium simultaneously. However, M3 has not been evaluated and adapted for Nigerian soils. Therefore, M3 as a multi-purpose extractant of P a...

ABSTRACT The dearth of up-to-date information on the Nigerian natural resources is a major hindrance to their optimal and sustainable use for national development. Remote sensing technique enables faster and more accurate acquisition of information than that of conventional approach to natural resources survey. However, their uses are yet to be fully exploited. This study was therefore designed to produce LandUse/LandCover (LULC) maps of Southwestern Nigeria using remote sensing technique an...

ABSTRACT Crop Rotation (CR) and planting of Cover Crops (CC) are important methods of weed management for sustainable crop production. These and various other methods are usually integrated to enhance weed management in crop production. While reports abound on integrated weed management involving these and other practices, there is inadequate information on integrated use of Pre-emergence Herbicides (PH), CC, and CR in maize production. Therefore, effects of continuous use of CC with PH were...
ABSTRACT Fifteen genotypes of okra were evaluated in eight environments for stability of seed yield, and also to identify the most suitable environments for producing high quality seed at the University of Ibadan, Nigeria from 1984 to 1986. There was significant genotype x environment interactions for all characters examined except for percent seed germination. On the average, highest seed yield and best seed quality as measured by percent seed germination were associated with environments wi...
ABSTRACT High and sustainable kenaf production in a fragile tropical soil requires the use of soil amendments. Arbuscular Mycorrhizae (AM) are important for nutrition of plants in nutrient depleted soils of the tropics. Due to insufficient information on kenaf production using fertilizers and AM, the effects of fertilizers and AM on soil chemical properties, growth and fibre yield of kenaf were investigated. Screenhouse and field experiments were conducted at the Institute of Agricultural Res...
