Peroxidase isozyme characterization of elite genotypes of Pearl millet (Pennisetum glaucum (L.) R. Br)

Isozyme markers are the oldest among molecular markers. Isozyme markers have been successfully used in several crop improvement programmes. Peroxidase (POX) isozyme has proven to be reliable genetic marker in breeding and genetic studies of Pearl millet. The present study was conducted to characterize 21 genotypes (7 hybrids, 6 female parents, 5 male parents and 3 open pollinated varieties (OPV) of Pearl millet by using...

The one-humped camel in Southern Africa: Unusual and new records for seven countries in the Southern African Development Community

The one-humped camel (Camelus dromedarius) was introduced to colonial southern Africa in the late 19th and early 20th centuries for military and police work to maintain law and order, for use in the postal services and for experiments in connection with rinderpest. Remnants of these (originally very small) populations survive in Botswana, Namibia and the Republic of South Africa but there are no surviving camels in...

The influence of fertilizer type and application rates in tea cultivation on nitrogen and potassium efficiencies

As the most important cultural practices for tea production, single effects of nitrogen (N) and potassium (K) fertilization on yield are well documented but their interactions and impact on their use efficiencies are poorly understood. It was necessary therefore to assess interactions and impact on their use efficiencies in tea cultivation as influenced by fertilizer application rates. This objective led...

Mathematical model for nursery raising inside greenhouse

Farmers require initially high input to raise nursery seedling/cuttings. Farmers’ further activity related to cultivation depends on healthy and available seedlings. Once a farmer has prepared the land and cannot get good seedling, he becomes weak for some season. Studying of environment is a must for planning nursery raising according to thermal profile which can be obtained in greenhouse. Keeping this in mind,...
