Physiological basis of genetic variability in drought response and its association with yieldand related indices is not clear in Brassica. In this study 36 accessions belonged to sevenspecies of Brassica were evaluated under normal, moderate and severe stress environments.Physiological traits along with seed yield, seed yield components, oil content and two selectionindices (stress tolerance in...

The unmanned aerial vehicles (UAV) have become a better solution for agricultural growers due to advanced features such as minimal maintenance costs, quick set-up time, low acquisition and live data capturing. Near-ground remote sensing (drone) has opened up new agronomic opportunities crop management. This study predicted the seed cotton yield field area located at Tamil Nadu Agricultural Univ...

Crop gross primary productivity (GPP) is an important characteristic for evaluating crop nitrogen content and yield, as well as the carbon exchange. Based on the close relationship observed between GPP and total chlorophyll content in crops, we applied a model that relies on a product of chlorophyll-related vegetation index and incoming photosynthetically active radiation for remote estimation ...

Assembly of plastid-encoded chlorophyll binding proteins of photosystem II (PSII) was studied in etiolated barley seedlings and isolated etioplasts and either the absence or presence of de novo chlorophyll synthesis. De novo assembly of reaction center complexes in etioplasts was characterized by immunological analysis of protein complexes solubilized from inner etioplast membranes and separate...

Soybean (Glycine max L.) is considered as one of the major sources of oil and protein. In this study, the effects of vermicompost (VC) and sulfur (S) on soybean photosynthesis responses, yield, and grain quality were studied. To this end, a split-plot design field experiment based on randomized complete blocks with nine treatments and three replications was conducted in Aligudarz city Lorestan ...

introduction: rosemary (rosmarinus officinalis l.) is a perennial, ever green and fragrant plant belongs to lamiaceae family. vegetative parts of this plant have essential oil and compounds with anti oxidant and antibacterial properties which are used extensively in pharmaceutical, food and cosmetic industries. the use of biofertilizers such as vermicompost and nitroxin could have beneficial ef...

Nieman et al. (16,17) and Bishop et al. (2) described the photooxidation of ferrocytochrome c by detergent treated chloroplasts as an oxygen-consuming, cyanide-insensitive process which was stimulated by a soluble chloroplast enzyme. In an earlier paper, we reported that the quantum yield of this reaction increases at wavelengths beyond 690 my (14), and concluded that only the first photoact is...
