Effect of bulb density, nitrogen application time and deheading on growth, yield and relative economics of daffodil cv. Tunis (Narcissus sp.)

A two years field experiment to study the effect of bulb density, nitrogen application time and deheading on the growth and bulb yield of daffodil cv. Tunis was conducted during winter seasons of 2009 to 2010 and 2010 to 2011 on silty clay loam soil, low in available Nitrogen, medium in available phosphorus and potassium with neutral pH. The study revealed that the bulb density at 15.0 t ha-1 proved significantly...

Xylem vessel element structure explains why columnar apple trees flower early and have higher yield

The vessel elements of secondary xylem in branches of columnar and normal apple trees were studied by isolation method and micrograph. The lengths and diameters were measured and the type of side wall (reticulate or pitted) was noted. Most of the perforation plates were simple. Normal apples had more abnormal vessel element cells than columnar apples. The average diameter of the xylem vessel elements of columnar apples...

Physiological and biochemical behavior in banana cultivars and hybrids under water deficit

Water deficit is a major problem in banana grown under tropical and sub-tropical region climatic conditions. It affects plant growth and development and ultimately leads to a considerable bunch yield reduction or crop failure. Although the banana cultivars and hybrids are susceptible to water deficit, there is a marked genotypic variation in morphology of the plant and rooting pattern in banana in response to water...

An analysis of the determinants of household level production and marketing of beans in Eastern Congo

Legumes and especially beans provide some of the most widely grown crops in the East and Central Africa region. The question of whether certain crops, specifically beans, are more beneficial to women than to men in relation to cash crops and other cereals, has been raised from time to time. In the central Africa region and in particular in the Democratic Republic of Congo (DRC), bean production has been promoted in the...

Rheological characterization and texture of commercial mayonnaise using back extrusion

When creating or redesigning food product researchers need to pay special attention to textural and rheological properties. Texture is a sensory perception derived from the structure of food and is related to viscosity and elasticity. Mayonnaise is semi-solid oil-in-water emulsion with starch in its formulations when fat-reduced. Under shear forces it exhibits different types of macroscopic flow behavior, such as shear...

Effect of transgenic cotton expressing Cry1Ac and Cry2Ab2 protein on infectivity of the entomopathogenic nematodes, Steinernema karii and Heterorhabditis bacteriophora

Entomopathogenic nematodes are used in biological control of pests. The cry proteins from insect resistant cotton may affect their infectivity. The effect of Bacillus thuringiensis (Bt) cotton (06Z604D) on infectivity ofHeterorhabditis bacteriophora and Steinernema karii was investigated in the green house. The nematodes were introduced into pots containing Bt cotton (06Z604D), isoline...
