Yield response to elevated soil boron in wheat cultivars of local and foreign origin

Abstract

The two-year field study was aimed to investigate the effect of increasing soil boron treatments (3.3, 6.7 and 13.3 g H3BO3/m2) on eight wheat cultivars, as well as to estimate the rate in which yield decreases followed the increase in soil boron. A strong positive linear relationship was found between the treatments and soil hot water extractable boron. On average, wheat yield response to elevated soil boron was decrease of 7.7%. Cultivars of local origin over-yielded foreign cultivars at all levels of boron supply. The estimated yield loss was 1.8% per increase in soil boron of 0.1 ppm.

Dvogodišnji poljski ogled je postavljen sa ciljem ispitivanja uticaja tretmana borom (3.3, 6.7 and 13.3 g H3BO3/m2) na osam sorti pšenice, kao i procene intenziteta kojim se prinos smanjuje usled rastuće koncentracije ovog elementa u zemljištu. Utvrđena je jaka pozitivna linearna veza između primenjenih tretmana i zemljišnog bora rastvorljivog u vreloj vodi. Prosečna redukcija prinosa pšenice na tretmanima iznosila je 7,7%. Kod lokalnih sorti je zabeležen viši prinos u odnosu na strane, bez obzira na tretman. Procenjeno je da porast koncentracije zemljišnog bora od 0,1 ppm za posledicu ima redukciju prinosa od 1,8%.
