This paper presents the results of research conducted during 2016-2021 regarding the influence of four soil tillage system and two fertilizer doses on emergences and maize yield, in the pedoclimatic conditions of the hilly area of the Transylvanian Plain. In all experimental years, a faster maize emergence was observed in the conventional-plow and minimum tillage-chisel compared to minimum tillage-disk and no-tillage. In a conventional system (control), the yield achieved (7603 kg ha-1) was close to the minimum tillage-chisel system (7529 kg ha-1), and higher than the minimum tillage-disk (6391 kg ha-1) and no-tillage (5178 kg ha-1). The beneficial effect of additional fertilization with CAN 27 (granular nitrogen fertilizer containing magnesium and calcium from dolomite) is found in a better development of plants and on the increase of yield with 356 kg ha-1 compared to the variant with basic fertilization. The yield difference between the two hybrids included in the experiment is insignificant (under 100 kg ha-1).

An energy saving way is that of implementing optimal technology specific to each culture and pedoclimatic area. The minimum tillage and no-tillage systems represent alternatives to the conventional system of soil tillage, due to their conservation effects on soil features and to the assured productions, maize: 96-98.1% at minimum tillage and 99.8% at no-tillage, soybean: 102.9-111.9% at minimum tillage and 117.2% at no-tillage, wheat: 93.4-96.8% at minimum tillage and 106.9% at no-tillage, as compared to the conventional system. Correct choice of the right soil tillage system for the crops in rotation help reduce energy consumption, thus maize: 97.3-97.9% at minimum tillage and 91.3% at no-tillage, soybean: 98.6-98.2% at minimum tillage and 92.8% at no-tillage, wheat: 97.4-98% at minimum tillage and 91.6% at no-tillage. Energy efficiency is in relation to reductions in energy savings, but also with efficiency and impact on the tillage system on the cultivated plant. For all crops in rotation, energy efficiency (energy produced from 1 MJ consumed) was the best in no-tillage and 10.44 MJ ha at maize, 6.49 MJ ha at soybean, 5.66 MJ ha at wheat. Energy-efficient 1 1 1 agricultural system: the energy consumed-energy produced-energy yield, necessarily have to be supplemented by soil energy efficiency, with the conservative effect of the agricultural system. Only then the agricultural system will be sustainable, durable in agronomic, economic and ecological terms. The implementation of minimum and no-tillage soil systems have increased the organic matter content from 2 to 7.6% and water stabile aggregate content from 5.6 to 9.6%, at 0-30 cm depth, as compared to the conventional system. While the soil fertility and the wet aggregate stability have initially been low, the effect of conservation practices on the soil characteristics led to a positive impact on the water permeability in the soil. Availability of soil moisture during the crop growth led to a better plant watering condition. Subsequent release of conserved soil water regulated proper plant water condition and soil structure.

The aim of this study is to evaluate the behavior of 75 European soybean genotypes from four maturity groups regarding the influence of climatic conditions of 2020 on soybean main growing and development stages. The experiment was conducted at the ARDS Turda in 2020, using a complete randomized block design with three replications. Dates of emergence (VE) and beginning of flowering (R1), were recorded for all 75 soybean cultivars from each of the four maturity groups (000 to I). Results obtained show that growing, and development stages of the studied soybean genotypes are according both with: thermal units and daily period from sunrise to sunset. Effects of daylength and temperature on soybean development were estimated. The rate of development to flowering was fastest for the very early genotypes than for genotypes in the semi-early maturity group (MG).

Soybean growers have invested into agronomic practices to maximize production and increase its potential, one of the practices are the usage of foliar fertilizer. In order to quantify the effects of foliar fertilization on soybean seed quality, an experiment was carried out at Research and Development Station for Agriculture Turda, in two consecutive years (2020-2021) and was based on a randomized blocks design with three replications. Seventy-five soybean genotypes from four maturity groups were analyzed. A small influence of foliar fertilization on soybean yield was observed with a slight decrease for the early genotypes when foliar fertilization in both growth and development stages were applied. Regarding the quality, an improvement of the chemical composition of soybean seeds can be reached by applying foliar fertilizers. The results from this study revealed that yields was not increased by treatments applied on soybean growing season.

Resulted plants could improve crop yield or to develop in less adequate geoclimatic conditions, responding those to challenges raised by global change. However, at now there are limited information on potential impact of such plants on soil properties and microbiota. Considering that microbiota are key mediators of soil functions and ecosystem processes it is important to fulfil such gaps. The objective of this study was to identify if different genetic varieties of Cherry tomato (Solanum lycopersicum), grown in same conditions, could influence root exudates (mainly carbohydrates) and rhizosphere microbiota profile. Randomized complete block rhizo-box experiment was performed with identic soil under similar growing conditions of genetic varieties Cherry tomatoes. PLFA and carbohydrates were analysed on GC-FID. In soil where tomatoes were grown the total PLFA amount was approximately two times higher compared with that detected from control (669.1 nmolg-1), which means that tomato root rhizosphere and exudates could influence soil microbiota. The average value of total PLFA for heirloom varieties was 1575.5 nmolg-1 while for hybrid varieties was 1269.4 nmolg-1. ANOVA test revealed significant differences between genetic type varieties of Cherry tomato (Solanum lycopersicum) rhizosphere microbiota community structure. Gram-positive, gram-negative bacteria and fungi abundance decreased in hybrid Cherry tomato varieties rhizosphere soils. Decreases in microbial and fungi community abundance may be related with decrease in carbohydrates content following with grown of different genetic hybrid varieties of Cherry tomato where some species exudates are reduced in essential carbohydrates content.
