<p>The present paper presents the results on the influence of the nutrition space at <em>Dracocephalum moldavica</em> L., cultivated under the conditions of A.R.D.S. Secuieni between 2016 and 2017. Following the interaction of the factors, the distance between the rows and the distance between the plants per row was found that in the variant sown at 70 cm between the rows and 15 cm between the plants per row there was an increase in the average number of branches (2,27). The variants sown at 50 cm and 70 cm between the rows achieved deficit production, very significant compared to the control sowing at the 25 cm between the rows.</p>

<p>In the lab, three sorghum hybrids for grains cultivated in the Center of Moldova were analyzed qualitatively, two of them having white grains, and one having red grains. Two of the hybrids, one with white grains (Albanus) and one with red grains (Alize) came from Euralis SAS France, and the third, with white grains, came from N.A.R.D.I. Fundulea Romania (Fundulea 32). The results obtained from the laboratory investigations indicated that the variation of the chemical composition of the sorghum grain depending on the cultivated hybrid.</p>

Existing information in the literature on the variation in tuber yield and their inulin content, depending on the variety and soil and climatic conditions of Helianthus tuberosus L., is limited. For this reason, in the pedoclimatic conditions from ARDS Secuieni (Center of Moldova) and from ARDS Caracal (Oltenia Plain) was conducted a study regarding this aspects. This study was conducted between 2018-2020, within an experiance with four genotype of Jerusalem artichoke and specifically: Dacic dwarf, Rareș, Olimpic and Dăbuleni population. The results obtained showed major differences between the cultivated genotypes and between the two agricultural areas, both in terms of tuber yield and tuber quality. Jerusalem artichoke is a species that has resistance to drought and high temperatures, achieving average yields of 21.3 to ha-1 in Secuieni and 24.0 to ha-1 in Caracal. The Oltenia Plain offered more favorable conditions for the growth and development of Jerusalem artichoke, but the species also successfully succeeded in Central of Moldova. Inulin was present in the tubers in a percentage between 48.35% and 58.38%, which confirms the high functional potential of the species and recommends the species as a “source of fiber”. Also, due to the high mineral content identified in the tubers, the mention of “iron source” and “magnesium source” may be issued.

<p>The present paper presents the results on the influence of the nutrition space at <em>Cassia angustifolia</em> Vahl. (Senna), cultivated under the conditions of A.R.D.S. Secuieni in 2017. The interaction of the studied factors was characterized by very significant negative differences to the production of fresh herb at <em>Cassia angustifolia</em> compared to the control variant (30666 kg/ha) at the distance between rows of 50 cm and 70 cm at all three distances between plants per row (continuous row, 15 cm and 25 cm).</p>
