Dynamic of blooming and formation of knots in tomatoes grown over luvic chernozem and in dependence of the form of nitrogen source

Mitova, I.
The influence of N-source over dynamic of blooming and formation of knots in tomatoes grown over medium Luvic Chernozem was established in experiment with tomato andldquo;N-10 х Bizon andldquo;sort in vessel experiment. The N-source norm from 800 mg N kg-1 soil and background of P and K fertilization was imported as a NH4NO3, (NH4)2SO4, Ca(NO3)2, Ca(NO3)2 + Mo, CO(NH2)2, CO(NH2)2 + inhibitor, CO(NH2)2 + inhibitor + Zn. As a correcting fertilization in some cases was added Mo- and Zn-fertilizer and inhibitor of nitrification. As a result of this study we find out: The earliest ripe fruits and the highest ripe fruits-yield are reported in plants fertilized with CO(NH2)2 + inhibitor+Zn. The plants fertilized with (NH4)2SO4 ripe later but they produce higher yield (ripe and unripe fruits). The biggest fruits are found in this variant of fertilization. The latest blooming and ripening and the smallest fruits are produced in the variant with Ca(NO3)2 + Мо.
