Effect of PEG Induced Drought Stress on Seed Germination and Seedling Characters of Maize (Zea mays L.) Genotypes

Drought stress is one of the most important environmental issues that reduce growth, development and yield of the plants. Developing maize cultivars that can perform well in drought and other abiotic stress is an important goal throughout the world. Germination is one of the main growth stages for seedling establishment, and success in this stage is dependent on moisture availability in the soil...


Potential of renewable energy technologies for sustainable rural development in Nepal

Majority of people in Nepal live in rural areas and are poor; though energy is vital for economic development and integral in domestic purposes, due to their poor economic condition, rural people consume less energy and rely on traditional energy sources.


Evaluation of various training aspects of agriclinics and agribusiness centres (ACABC’s) scheme in Rajasthan, India

he various training aspects of the agriclinics and agribusiness centre scheme and these training aspects includes information about the training programmes, place of training, year of completion, factors motivated to join training programme, facilities provided by the training institutes, study material, courses offered in training, classes conducted by the training institutes, seriousness of candidate about training and final feedback of the trainees about training programme.


Isolation and characterization of Ralstonia solanacearum causing bacterial wilt of solanaceae crops

There exists a lot of controversy regarding the prevalence of strains in the various parts of the world. In India, however, scant information is available about the prevalence of biovars/races and strains in various parts of the country. Understanding local pathogen genetic diversity is the first step in a successful breeding and integrated disease management programme. One of the purposes of the present investigation on six isolates of R. solanacearum causing wilt on tomato and brinjal isolated from different agro-climatic zones of Karnataka is to characterize then into races, biovars and phylotype.


The status quo of knowledge management and sustainability knowledge

Organizations that aspire to be economically viable as well as socially and environmentally responsible global citizens, need to understand what sustainability means and how to institutionalize its principles. This paper posits that some of the underlying reasons for slow progress are lack of full understanding of the required knowledge and its systemic nature, as well as potentially insufficient knowledge management processes. It proposes that sustainability knowledge learning should include three “DCA” steps: 1) What to know: identify which knowledge is needed (DEFINE); 2) How to learn : develop strategies to identify sources and learning strategies for the requisite sustainability knowledge (COLLECT); 3) How to use sustainability knowledge: develop knowledge management practices that enable absorption and institutionalization (ACT).


Soil quality refurbishment through carbon sequestration in climate change: A review

The restoration of soil quality through carbon sequestration is major concern for tropical soils. The accelerated decomposition of soil organic carbon due to agriculture resulting in loss of carbon to the atmosphere and its contribution to the greenhouse effect is a serious global problem.


Histomorphology of thymus gland in Guinea fowl (Numida meleagris)

The thymus was collected from day old to nine months of age at monthly interval. Histomorphologically, the thymus gland in guinea fowl consists of cortex and medulla. Cortex was composed of small and medium sized lymphocytes, myoid cells and few Hassall’s corpuscles located in the meshwork of reticular cells. The medulla consisted of less densely packed medium and large sized lymphocytes with relatively more reticular cells and Hassall’s corpuscles. The reticuloepithelial cells were large cells with long cytoplasmic process located in both the region. Myoid cells were frequently found in the medulla and in the corticomedullary region, occasionally found in the cortex.


Constraints in adoption of improved cultivation practices of black gram

In this context the present study was undertaken to study the adoption of improved cultivation practices of black gram and identify the constraints as perceived by black gram growers.


Physiological and biochemical basis for moisture stress tolerance in chickpea under pot study

Water deficit stress is one of the important factors limiting chickpea production in arid and semiarid regions. Water deficit induced b Polyethylene glycol (PEG) affect physiological and biochemical changes in Chickpea. This investigation was undertaken to evaluate morpho-physiological parameters, levels of osmolytes and activities of antioxidative enzymes under PEG 6000 induced osmotic moderate and severe stress in pot. The plants were subjected to two progressive stresses: moderate (-0.4 MPa) and severe stress (-1.2 MPa).
