Optimum tillage system for pepper production in an alfisol of South-western Nigeria
Optimum soil tillage for different crops in different regions needs be established for good yield. For pepper production on an alfisol with soil texture on the surface soil, this paper investigated three tillage systems (Plough-Plough Till – PPT, Plough-Harrow Till – PHT and Plough-Ridge Till – PRT) and two compaction levels induced by a 50 kW MF tractor (5 and 10 tractor passes – 5P and 10P)...

The impact of irrigation water quality on water uptake by orange trees
A greenhouse lysimeter study was carried out in Tottori (Japan) during August 2000 to explore the impacts of saline irrigation on water uptake by orange trees. Two lysimeters filled with sandy soil were used. Each lysimeter was planted with a tree. During the first half of August, both lysimeters (L1 and L2)[b1] were irrigated with non-saline water. In the second half of the month, L1 was irrigated with non-saline...

Preliminary assessment of shea butter waxing on the keeping and sensory qualities of four plantain (Musa aab) varieties
Over the last few years, the production of plantain has been increasing due to the introduction of some high yielding varieties. Unfortunately, very high post-harvest losses are incurred annually due to lack of appropriate storage technologies. This study evaluated the effect of shea butter as a food-grade wax on the pre-climacteric life and sensory qualities of four plantain varieties...

Optimisation of protoplast isolation protocols using in vitro leaves of Dendrobium crumenatum (pigeon orchid)
Protoplast isolation from in vitro leaves of Dendrobium crumenatum was carried out. Factors affecting protoplast isolation, sorbitol concentration, enzyme combinations and concentration and incubation time for isolation were studied. Results obtained showed that 0.5 M sorbitol was the most effective concentration to isolate the protoplast (25.62×104 protoplasts/g FW). High yield of...

Mycoflora and nutritional components of cocoa powder samples in South West Nigeria
The production of cocoa powder (CP), the major ingredient of cocoa-based beverages, has been on the increasing trend in Nigeria without much concern for whether or not they meet the microbiological criteria for food safety. This study was, carried out to investigate the mycroflora and intrinsic factors of twenty four brands of cocoa powder samples bought from different sources in South-West Nigeria with a view to...

Effect of different plant growth regulators on callus induction in Catalpa bungei
The present study describes a reliable method for callus induction of Catalpabungei plant. Calli were in vitro initiated from leaves, stem and petiole segments using DKW basal media. The effect of combinations of BA (6-benzyl adenine) and NAA (α-naphthalene acetic acid) on callus induction was investigated. It was found that growth regulators and their concentrations have obvious effects on the...

Changes of the lipid peroxidation and chlorophyll amount of green bean genotypes under drought stress
One of the environmental stresses, and maybe one of these important drought stresses, cause deterioration of oxidative on the plant cell. Beans is one of the vegetables influenced by high level of drought. Drought stress deterioration effects on beans and its aim determines these effects either as been different or not caused by drought stress dependent on 10 item beans (Phaseolus...

The screening wheat (Triticum aestivum L.) plants for moderate phytate content using colorimetric values of semi-grain seeds
To select wheat cultivars with moderate phytate content, in this experiment the authors found out a new method quickly screening individual plant in huge offspring. Twenty-three wheat cultivars were twice planted at two places. For one part of the seeds harvested, they randomly cut them into two semi-grain seeds one by one, the semi-grain seeds without embryos were assayed by colorimetric values in some micro-test...

Inheritance of hyper sensitive response to Striga parasitism in sorghum [Sorghum bicolor (L.) Moench]
Striga parasitism involves a series of events occurring beneath the soil surface. The complex nature of host/parasite interactions and the influence of environmental factors have limited our knowledge of host plant resistant mechanisms and their genetics and slowed the breeding for resistance efforts. However, the development of the new laboratory screening assays in our laboratory, have improved our understanding...
