Recently developed landmark-based geometric morphometry has been used to depict the morphological development of organisms. In geometry, four landmarks can be mapped to any other four by Möbius transformations, if the cross-ratio of the landmarks is invariant and vice versa. To geometrically analyze the morphological development of the human body, we examined the cross-ratio of three consecutiv...

It is well known that mechanochemically activated phosphate rock (MAPR) could improve extractable phosphorus (P) (extracted in 2% citric acid) greatly an ecological way. To evaluate the agronomic effectiveness of MAPR, we conducted a field experiment using spring maize Luvisol (pH 6.47) soil Northeast China for three consecutive years. Treatments consist variation P levels substitution triple s...

Rock phosphates are less soluble and agronomically not as efficient the acidulated. However, some rhizobacteria can improve solubilization of inorganic in soil, raising efficiency rock phosphates. The objective was to evaluate development maize plants response application P sources associated with inoculation. A greenhouse experiment carried out six sources: no application; ​​Triple Superphosph...

Abstract—The enhanced need for food items is receiving more importance due to a gradual increase in the world population and, in this scenario, fertilizers play a very important role in agriculture. In this study, the production of the normal superphosphate was investigated with a continuous chamber method by adding potassium chloride to a mixture of Hibin apatite and Kingisepp phosphorite. In ...

A pot experiment was carried out to study the phosphrous-sulphur interaction at Department of Agricultural Chemistry and Soil Science, Rajasthan College of Agriculture, Udaipur on a sandy loam soil (Typic Haplustept) medium in P and deficient in S with clusterbean. The treatment consisted of three levels of P (0, 20 and 40 kg P O ha ) and three levels of S (0, 10 and 20 kg ha ) applied from gyp...
