THE FERTILIZATION EFFECT ON THE PRODUCTION OF BEANS GRAINS AND THE PROTEIN CONTENT IN THE SOIL AND CLIMATE CONDITIONS OF THE BANAT PLAIN PUBLISHEDAna Maria Andronache, Ioan Borcean None
Researches have been done in the most favorable areas for the cultivation of beans, on a black, humid and very fertile soil type, that is in an iron oxides reduction process. The experiences were trifactorial, organized after the divided lot with three repetitions method. The studied factors were: Factor A – the cultivated type(Avans and Diva); Factor B – the fertilization with nitrogen(40 kg/ha P2O5 and 80 kg/ha P2O5); Factor C – the nitrogen dose(N0, N50, N100). In this study are presented data concerning the influence of the factors on the plant’s height, the number of ramifications per plant, the number of pods per plant, the number of beans per pod, the weight of the beans per plant and the variation of the mass of 1000 beans. The harvest variation was between 1400 kg/ha and 2600 kg/ha, the mass of 1000 beans had an amplitude between 1809 and 4339 and the protein content was between 24,22% and 28,11% for the Avans type and between 24,46% and 28,06% for the Diva type. The height of the plants has grown, under the influence of fertilization, from 40,30cm (N0P40) to 45,50cm (N100P80) at the Avans type and from 34,40cm (N0P40) to 45,50cm (N100P80) at the Diva type. The number of ramifications per plant has grown from 4,30 (N0P40) to 5,80 (N100P80) at the Avans type and from 3,60 (N0P40) to 5,90 (N100P80) at the Diva type. The number of pods per plant, in the researched domain, has grown from 15,60 to 22,50 at the Avans type and from 13,60 to 20,40 at the Diva type. The number of beans per pod was almost the same for each type; the result was between 4,80 (N0P40) and 5,50 – 5,80 (N100P80). The results of the biometrical measurements are in positive relations with the results of the harvest.
