Phenamiphos applied at 6.7 kg ai/ha through a solid set or a center pivot irrigation system with 28 mm of water effectively controlled root-knot nematodes, Meloidogyne incognita, and resulted in greater snap bean growth and yields irrespective of growing season, tillage method, or cover crop system. The percentage yield increases attributed to this method of M. incognita control over nontreated...

Effect of treatment with different concentrations of N-nitroso-N-ethyl urea (ENU) and etylmethan sulfonate (ЕМS) on seeds of Bulgarian common bean Dobroudjanski 7, Dobroudjanski 2, Plovdiv 10, Plovdiv 11М and snap bean Tcher Starozagorski varieties, for induction of chlorophyll mutants, was studied. It was established that investigated varieties manifested specifi c reactions to the treatment w...

Understanding the mechanisms that regulate xylem transport of calcium (Ca) to snap bean (Phaseolus vulgaris L.) pods could allow approaches to increase pod Ca concentration and enhance the nutritional value of edible pods. Using the snap bean cultivars Hystyle and Labrador, which exhibit high and low pod Ca levels, respectively, we wished to determine whether there were differences between the ...
