The objective of this study was to investigate the effect of foliar fertilization as compared to mineral fertilization on yield and yield components of soybean. The experiments were carried out during 2020 and 2021 growing seasons at Research and Development Station for Agriculture Turda (RDSA Turda), Romania, using randomised complete block design with three replications. The two variants of foliar fertilization contain macro and micro elements, being applied in different phases of soybean growth and development. Among the foliar fertilization options, T1 stood out as the foliar fertilization option that contributed to some extent to the growth of plant height, the number of pods/plant, the number of grains/plant, the weight of grains/plant and yield. The second variant of foliar fertilization (T2) in most of the analysed cases determined a decrease in the yield elements as well as the yield compared to the control variant. [ABSTRACT FROM AUTHOR]

The choice of a mixed structure of fodder crops, including annual and perennial species, becomes a necessity for Romanian farmers due to the droughty periods recorded during the vegetation period of fodder plants. The choice of some species with good adaptability at drought and high forage yields in such climatic conditions has no less importance. Moreover, the application of a proper fertilization influences both the reaction of species at climatic conditions and the level of obtained yields. This study aims to find species/crops and fertilization levels which can provide good forage yields in drought conditions. In this respect six crops represented by two mixtures as oat + peas (control - C1) and triticale + pea (C2), respectively by four pure crops as rape (C3), millet (C4), sorghum x Sudan grass hybrid (C5) and sweet sorghum (C6), on three levels of fertilization (N0P0 kg∙ha-1 - F1, N60P70 kg∙ha-1 - F2 and N120P70 kg∙ha-1 - F3), were studied. The study was undertaken in 2011 when the rainfall level during sowing-harvesting period (March-July months) was with 362.65 mm lower than in 2010 and with 184 mm lower than in 2009, respectively. Sweet sorghum and sorghum x Sudan grass hybrid fertilized with N60P70 kg∙ha-1 and N120P70 kg∙ha-1 doses were revealed with significant high dry matter yield among the studied crops and experimental variants (crop x fertilization). Among the mixtures of annual grasses and legumes taken into the study and which can be used in pig farming within experimental area, in a descending order, considering the obtained yields, the following variants can be recommended for farmers: triticale + peas fertilized with N120P70 kg∙ha-1 dose and unfertilized oat + peas.

Crop biomass is more and more of interest as raw material for producing different kinds of energy as it is renewable and contribute significantly to the mitigation of the green house effect. The crop biomass is increasingly used as substrate for producing biogas. In this respect, it is widely appreciated that maize is one of the most important crop for producing biomass which can be used for biogas production. But, together with maize there are other several crops that are suitable for producing biomass that could be used as substrate for producing biogas. Among this crops, there is included the triticale crop, which could provide important yields of biomass at late spring and early summer, depending of the growing area. The aim of the paper is to present the above-ground biomass yield at different varieties of triticale (Negoiu, Mezin, Cascador, Haiduc, Stil, Gorun 1, Polego, Tulus, Titan, Oda) in some of the most important plant growth stages and in the specific conditions from South Romania. Also, it is aimed to present the results obtained in the medium milk growing stage regarding the share of biomass on plant components, the moisture content of plant components, as well as regarding plant height and stem diameter at soil level. Researches were performed in 2012/2013 in field experiments located in South Romania, on a reddish preluvosoil. [ABSTRACT FROM AUTHOR]

High nature value (HNV) grassland systems are increasingly important for the ecosystem services they provide and for their socio-economic impact in the current constant-changing context. The aim of our paper is to evaluate the long-term effect of organic fertilizers on HNV systems in the Apuseni Mountains, Romania. As an objective we want to identify the optimal intensity of conservation management and its recognition based on indicator value plant species. The experiments were established in 2001 on the boreal floor and analyze the effect of a gradient of four organic treatments with manure. Fertilization with 10 t ha−1 manure ensures an increase in yield and has a small influence on diversity, and could be a real possibility for the maintenance and sustainable use of HNV. Each fertilization treatment determined species with indicator value that are very useful in the identification and management of HNV. The indicator species are useful in forecasting the fluctuations and successions in grasslands, determined by the modification of the dominance-codominance ratio and the real coverage of each species.
