Multivariate statistical techniques such as cluster analysis, multidimensional scaling and principal component analysis were applied to evaluate the temporal and spatial variations in water quality data set generated for two years (2008-2010) from six monitoring stations of Veli-Akkulam Lake and compared with a regional reference lake Vellayani of south India. Seasonal variations of 14 differen...

Sixty six genotypes of cowpea (Vigna unguiculata (L.) Walp) were investigated to understand the extent of genetic diversity through twelve quantitative traits. Mahalanobis’s D analysis established the presence of wide genetic diversity among these genotypes by the formation of 23 clusters. Cluster I had the maximum number of genotypes i.e 22 and cluster 23 had only one genotype. Intra cluster d...

A field experiment was conducted to study the rate of dissipation thiamethoxam 25% WG in vegetable cowpea. Thiamethoxam 25%WG @ 0.24 ml l-1 sprayed at pod formation stage, and samples pods were harvested 0 (2 hr after spray), 1, 3, 5, 7, 10, 15 days spray. Residues estimated using liquid chromatography tandem mass spectrometer (LC-MS/ MS) All-India Network Project on Pesticides Residues, Colleg...

nature has always proven that it is able to overcome its problems. however, humanmanipulation has led to environmental degradations. the dryness of a thousand-year urmia lake(a brine water lake in iran) is an example of environmental degradation that happened due tosuccessive droughts and construction of dams on the basin of this lake. this study examinesmethods for the revival of urmia lake by...

According to the water resources and climate change and challenges of Urmia Lake basin, which is the discharge and final destination of North West Rivers, a model was presented. Due to climate change and water resources in river basin such as rainfall, climate change in basin that has direct impact on evaporation over water catchment areas and lake water, this model can be provided. In addition...

Effect of rootstock on yield and quality cucumber scion was studied at Department Vegetable Science, College Agriculture, Vellayani, Thiruvananthapuram, Kerala during February-May, 2021. Parthenocarpic non-parthenocarpic scions were grafted onto five different cultivated cucurbit species i.e. pumpkin, bottle gourd, oriental pickling melon, culinary melon ash gourd. Significant variations observ...
