Sorghum can be an excellent source of starch, protein, sugar, fiber, being cheaper than corn, because the costs/ha are lower than corn. It has a great development due to its use in food industry, especially in semi arid areas of the world where the climatic conditions offer limited conditions for agriculture. In this paper, we managed to prove how important is the proper fertilization with nitrogen and phosphorus in forming the number of shoots/field and how important is the ensuring of an optimal seeding density on the formation of main plant in the sorghum field. Considering the importance of plants number in field, the main objective of the researches conducted during 2013 - 2014, was to study the sprouting ability of sorghum plants and the influence of some technological factors on it, knowing their direct influence in forming the field and indirect influence on grain production. In the experimental field of Agricultural Research - Development Station Secuieni, we placed an experience of 3 x 4 x 4 type, where we study at three hybrids of sorghum for grain, the influence of sowing density and nitrogen and phosphorus fertilization on Sorghum bicolor L. plantlets ability to sprout. The obtained results highlight the fact that the nitrogen and phosphorus fertilization contribute to the increasing of the shoots number/plant, but the sowing density negatively influence their formation. The correlation between nitrogen and phosphorus fertilization and the shoots number/ha was direct, the correlation coefficients were statistically ensured and interpreted as very significant, while that between sowing density and shoots number/ha was indirect, in this case, the correlation coefficients were interpreted as negative very significant. x [ABSTRACT FROM AUTHOR] |
