Small field plot experiments were carried out at the testing station of Central Control and Testing Institute in Agriculture VeÄžkĂ˝ Meder (Slovakia) experimental years 2014/2015, 2015/2016 2016/2017. Selenium salts form sodium selenite selenate applied growth phases: end tillering (BBCH 29) flag leaf ligule collar visible 39). The effect 2016/2017 on yield wheat grain was not statistically sig...

A study was conducted in the field to identify the N application stages which greatly determine spikelet differentiation and degeneration of rice (Oryza sativa L.). Spikelet differentiation and degeneration were greatly influenced by time of N application. N application at the neck-node differentiation stage significantly increased spikelet differentiation and that at the active meiosis stage s...

Maize developed from its ancestor, teosinte, about 10,000 years ago. The evolution has gone teosinte with multiple tillers to single-tiller maize plants. An investigation took place identify and sequence genes related tillering ability in perform In silico analysis. Mating proceeded by manual pollination between the commercial hybrid SC2031 of (Zea mays L.) genotype Domiata (Durra rayyana). par...

The experiment was planned to investigate the tractor mounted N-sensor (Make Yara International) to predict nitrogen (N) for wheat crop under different nitrogen levels. It was observed that, for tractor mounted N-sensor, spectrometers can scan about 32% of total area of crop under consideration. An algorithm was developed using a linear relationship between sensor sufficiency index (SIsensor) a...

This article presents the results of studies effectiveness use biological products in winter wheat crops. The positive effect pre-sowing seed inoculation with Azotofit and Help Growth on germination capacity seeds Skagen variety has been established which was 3-4% higher than control contributed to an increase number nodal roots by 56% 50%, respectively, plant density 13-9 pcs / m2 more control...

Metre-resolution airborne multispectral images have been used to estimate crop biomass in rice (Orysa sativa L.). Images were acquired at four stages of crop development; mid-tillering, flowering, panicle initiation and immediately prior to harvest. The imaging system, flown in a light aircraft, comprised four CCD video cameras; recording in the infrared, red, green and blue wavebands. Normaliz...
