Prinos pasulja u združenoj setvi sa kukuruzom tolerantnim na cikloksidim

Abstract

Pasulj i kukuruz gajili su se združeno pre stvaranja hibrida kukuruza upotrebe herbicida. Stvaranjem hibrida kukuruza tolerantnih na cikloksidim opet je moguće njihovo združivanje i to uz zaštitu od korova uključujući i višegodišnje travne korove primenom selektivnih herbicida za oba useva. U radu prikazujemo variranje prinosa pasulja (sorta Maksa) posejanog u neizmenične trake sa kukuruzom (NS 444 ultra, tolerantan na cikloksidim) u zavisnosti od načina zaštite od korova (kontrola bez i sa okopavanjem i tri herbicidna tretmana) i vremenskih prilika. Bolja je kombinovana primena herbicida posle setve-pre nicanja i u vegetaciji, posebno u godini lošijoj za razvoj pasulja.

Beans and maize used to be grown in intercropping. With development of maize hybrids tolerant to cycloxydim, it is possible to grow them in intercropping again, with weed control including perennial grass weeds, thus applying selective herbicides for both crops. Bean yield variations (cultivar Maksa) are shown in this paper. Cultivar was sown in alternate bands with maize (NS 444 ultra, tolerant to cycloxydim) depending on methods of weed control (without and with hoeing and three herbicide treatments) and weather conditions during two growing seasons of bean. Combined application of herbicides after sowing, before emergence and during growing season showed better, especially in a year less favourable for bean development.
