Maize performance in a sandy loam ultisol amended with NPK 15-15-15 and poultry manure
Most of the soils in the tropics are known to be poor in fertility status and poor resource farmers do not often have the finance to procure adequate fertilizers needed for their crop. Hence, there is the need to supplement soil nutrients for optimal crop performance. A greenhouse study was carried out at the University of Nigeria, Nsukka to evaluate maize performance using different rates of poultry manure (PM) and NPK...

Spatial variability of soil color parameters and soil properties in an alluvial soil
Understanding of spatial variability of soil properties provides the factors and processes controlling their potential in agricultural production. The objectives of this study were to analyze spatial structure of soil properties and soil color parameters (L*, a*, b*) in an alluvial field (45 ha) under different crop patterns, and to map soil properties using geostatistical methods. A geostatistical sampling scheme was...

Drying kinetics and quality characteristics of beetroot slices under hot air followed by microwave finish drying
The experiments were conducted to evaluate the impact of air temperature and microwave power level on drying behavior and quality of beetroot. The osmotically pretreated samples in sugar-salt mixed solution were further dehydrated using convective tray drier upto a moisture content of 40 to 60% db (the point where drying rate became slow) followed by microwave drying to a moisture content of 6% (bone dry...

Growth, productivity and quality of soybean [Glycine max (l) Merrill) under different levels and sources of phosphorus and plant growth regulators in sub humid Rajasthan
In India, soybean is the third largest oilseed crop but its productivity is lower and that can mainly be related to low fertilizer phosphorus usage, poor phosphorus use efficiency and flower and bud drop. In this backdrop, to achieve sustained higher soybean productivity, twenty seven treatments [three doses: 20, 30 and 40 kg P2O5 ha-1; three sources: single super phosphate (SSP), phosphorus rich organic manure (PROM)...

Genetic relationship between sesame (Sesamum indicum L.) and related wild species based on chromosome counts and isozyme markers
Sesame is an orphan crop with little research attention in Kenya. Genetic relationship between cultivated sesame and related wild species in Kenya is not well known. The objective of this study was to determine genetic relationship between traditional landraces of sesame and related wild species using somatic chromosome counts and isozyme markers. Somatic chromosome counts of four wild species revealed a consistent...
