Research on establishment of tehnological links to Gypsophila paniculata L. on sandy soils

Английский. Diversifying the range of plants grown on sandy soils, by introducing the culture of some species able to exploit existing natural conditions and which also contributes to their setting is a necessity. Research conducted at Central Research Station for Agricultural Plants on Sandy Soils of Dabuleni, Dolj county, Romania, in Gypsophila paniculata L. in sandy soil conditions, have demonstrated the possibility of introducing the culture of this species to exploit these types of higher ground. In type bifactorial experience was aimed at establishing the distance between the lines and the amount of useful seed, used for sowing, taking into study four distances between rows (37.5 cm, 50 cm, 62.5 cm and 75 cm) and three standard seed (4 kg/ha and 6 kg/ha and 8 kg/ha). The standard distance between rows and sowing the seed used in the production of roots influences. Normal growth of seed from 4 kg/ha to 6 kg/ha and 8 kg/ha is not justified in terms of production. By sowing at a distance of 62.5 cm between rows, using a quantity of seed sown useful to 4 kg/ha, there was a production of 11 t/ha, which enables us to opt for inclusion in the culture of the species Gypsophila paniculata L. sandy soils in southern Oltenia.

Diversificarea sortimentului de plante cultivate pe solurile nisipoase, prin introducerea in cultura a unor specii capabile sa valorifice conditiile naturale existente si care sa contribuie, totodata, la fixarea acestora se impune ca o necesitate. Cercetarile efectuate la CCDCPN Dabuleni-Dolj, la Gypsophila paniculata L., in conditiile solurilor nisipoase, au demonstrat posibilitatea introducerii in cultura a acestei specii, in vederea valorificarii superioare a acestor tipuri de sol. Intr-o experienta de tip bifactorial, s-a urmarit stabilirea distantei dintre randuri si a cantitatii de samanta utila, folosita la semanat, luindu-se in studiu patru distante intre randuri (37,5 cm, 50 cm, 62,5 cm si 75 cm) si trei norme de samanta (4 kg/ha, 6 kg/ha si 8 kg/ha). Atat distanta dintre randuri, cat si norma de samanta folosita la semanat influenteaza productia de radacini. Cresterea normei de samanta de la 4 kg/ha la 6 kg/ha, respectiv 8 kg/ha, nu se justifica din punctul de vedere al productiilor realizate. Prin semanatul la distanta de 62,5 cm intre randuri, folosind o cantitate de samanta utila la semanat de 4 kg/ha, s-a realizat o productie de 11 t/ha, care ne indreptateste sa optam pentru introducerea in cultura a speciei Gypsophila paniculata L. pe solurile nisipoase din sudul Olteniei.
