Effect of some Broomrape Control Treatments and Plant Densities on Productivity of Two Faba Bean Varieties (Vicia faba L.)

Abstract

Experimental field was carried out in naturally infested field with broomrape at Sakha Agricultural Research Station, Kafr El-Sheikh Governorate, Egypt, during two growing seasons 2015/2016 and 2016/2017 in order to study the effect of broomrape control treatments and planting density on faba bean productivity. In this study, we used two faba bean varieties (Misr 3 and Sakha 4), two plant densities (one side and two sides) and some broomrape control treatments (rhizobium at 20 g kg-1seeds, glyphosate twice at 36 g fed-1., rhizobium + glyphosate, hand pulling twice and untreated check). A split split plot design with four replicates was used. The results showed that the highest reduction in number of broomrape spikes plant-1, number of broomrape m-2 and dry weight of broomrape was recorded for Misr 3 variety with planting on one side and spraying glyphosate twice by (96.6, 97.9 and 98.0 %) in the first season, and by (96.2, 97.2 and 97.5 %) in the second season, respectively as compared to untreated Sakha 4 variety and planting on two sides. The highest yield of seeds (ardab fed-1) was obtained from Misr 3 variety with planting on two sides and spraying glyphosate twice + rhizobium treatment which surpassed by (84.8 and 88.5 %) in both sowing seasons, respectively as compared to untreated Sakha 4 variety and planting on one side. Thus, from the aforementioned results, could be recommended that the best control package for growing faba bean in soil infested with broomrape by planting Misr 3 variety with two sprays of glyphosate + rhizobium with planting on one side in kafr El-Sheikh area.
