Effets de la variabilité de deux doses différentes de bore sur deux stades phénologique de la floraison sur : la fécondation et nouaison du poirier (variété Santa Maria)

Abstract

The Perry take the fourth place among the most popular fruits in the world after citrus, bananas and apples. In Algeria, the weakness of production and yield of pore are _conditioned by several factor including soil and climatic factors, the genetic program of the species cultivated and crop management by the different farming technique. Given the contraints of production and mainly those weather accidents that have indirect effects on lowering the yield, affecting fertilization. Our study objective is to test the effect of boron by sprays at the beginning of flowering and full bloom with two different doses on the pear variety (Santa Maria) for fertilization, and higher rate of fruit setting and therefore improved performance. The results confirmed that foliar applications of boron solution On the pear variety (Santa Maria) at the beginning of flowering resulted in an improvement of the fertilization rate and consequently increasing fruit set of numbers which will result in a higher fruit production in quantity and quality.
