STUDY ON THE IDENTIFICATION OF HERBICIDES WITH HIGH SELECTIVITY TO ENSURE CULTURAL HYGIENE IN GRAIN SORGHUM CROPS

The integrated management of weeds uses a combination of biological, cultural, mechanical and chemical measures to combat the weeds in order to maximize the economic profits. Integrated management strategies for cultural hygiene are not sufficiently developed for selective herbicides in order to combat weeds for Sorghum bicolor (L.). The efficacy of the applied herbicides was tested using the Abbott’s formula, and the most effective in controlling weeds in the grain sorghum culture for the Caracal Plain area was found to be the Trek P 334 SE herbicide, with a value of 97.21%, followed by Gardoprim Plus with a calculated coefficient of 95.33% and the herbicide Wing P whose value was 94.15%. The lowest coefficient was recorded for the Casper herbicide, 73.28%. The level of productions made this year in the herbicide experiment using the Alizee hybrid range between 3092 kg/ha at the Control variant and 8150 kg/ha when the Trek P 334 SE herbicide was applied. The increases recorded in all variants with herbicides, regardless of the active substance contained, have achieved very significant increases in production in comparison with the Control variant

CONSIDERATIONS CONCERNING THE COMPOSTING OF ORGANIC WASTE

Compost means a product obtained by an aerobic, thermophilic, decomposition process and microbial synthesis of the organic substances in the residual products, which contains over 25% relatively stable humus predominantly composed of microbial biomass and which is subsequently subjected to a slight decomposition. stable enough not to reheat or cause problems with smell or breeding of insects and has the ratio C: N = 10-15 Regardless of its origin and nature, organic matter, depending on the conditions of aeration and humidity, evolves towards a new qualitative state, relatively stable to biodegradation, characterized by a humus-likeC:Nratio. Â

AGRICULTURE 4.0 - THE USE OF SMART TECHNOLOGIES FOR HIGHPERFORMANCE AGRICULTURE

Given that the labor market in Romania has an acute shortage of labor (about 1 million people), in agriculture this lack is felt even more acutely because the population in the villages is declining and aging, thus it is increasingly difficult for Romanian farmers to find labor, let alone skilled labor. One solution can be the digitization of agriculture, ie the introduction of the latest management concepts, sensors, automation, robots, etc. in the modernization of work processes in agriculture, thus reducing the need for labor, while increasing productivity and efficiency in agriculture

CONSTRUCTION TYPES OF TECHNICAL EQUIPMENT FOR DOSING, WEIGHING, PACKAGING AND PROCEDURES USED IN MILLING UNITS

The paper presents several types of technical equipment for dosing, weighing, packaging and the procedures used in the milling units. The weighing systems take into account several important criteria for their design, namely: how the weight or mass of the load is offset and how the result is transferred

AGRICULTURE 4.0 - A CHALLENGE FOR ROMANIAN AGRICULTURE

CONSIDERATIONS CONCERNING THE VALORIZATION OF THE JUICE OBTAINED FROM SUGAR SORGHUM STALK FROM ALCOHOL

 With a high production per hectare, sugar sorghum is a high value technical plant for farmers because from an average production of 70-80 t/ha, a high quantity of juice can be obtained, which can be used as such in the food industry (natural sweetener) or processed for the purpose of obtaining alcohol. The alcohol has a higher value/liter, can be stored more easily and its uses are multiple: in the food, pharmaceutical, chemical industry, etc
