Effect of faba bean sowing distance and some combinations of mineral nitrogen levels with bio-fertilizers on sugar beet and faba bean productivity under intercropping system

Abstract

FIELD experiment was conducted at Sakha Agric. Res. Station, Kafer EL-Sheikh Governorate, Egypt during 2013/2014 and 2014/2015 seasons to study the relative advantage of intercropping faba bean (variety Giza 643) with sugar beet (variety Geloria) and its impact on yield and quality attributes of both crops. A split plot design with three replications was used. The treatments of faba bean sowing distance (10, 20 and 30 cm) allocated in the main plots, while, the ten combination of nitrogen levels with bio fertilizers (90, 72, 54, 36 kg N/fad, 72, 54, 36 kg N/fad + Cerealine, 72, 54, 36 kg N/fad + Rizobacterine) were arranged in sub plots, the obtained results showed that:

Effect of Intercropping Faba Bean with Sugar Beet on Yield and Yield Components under Salt Affected Soils Conditions

“…These results are in agreement with those obtained by Mohammed et al (2005) and Ibrahim (2018). El-Shamy et al (2016) found that intercropping faba bean at low plant density (17,500 plant fed -1 ) with sugar beet gave the greatest values of root yield fed -1 in both seasons and number of leaves plant -1 in the first seasons only, while the high faba bean plant density (70,000 plant fed -1 ) achieved the lowest values of sugar beet traits.…”

“…The intercropping pattern includes 100% sugar beet plus 12.5% faba bean recorded the highest sugar beet root yield, while the highest LER and net income recorded with 100% sugar beet + 33% faba bean (Mohammed et al 2005). El-Shamy et al (2016) found that the faba bean plant density (17,500 plant fed -1 ) gave the greatest values of number of branches plant -1 , number of pods plant -1 , number of seedsplant -1 , weight of 100 seeds, straw yield fed -1 , seeds yield fed -1 , protein percent, root diameter (cm), fresh leaves weight plant -1 , fresh root weight plant -1 , dry leaves weight plant -1 , dry root weight plant -1 and root yield fed -1 in both seasons and number of leaves plant -1 in the first seasons only, while the dense population of faba bean plants (70,000 plant fed -1 ) recorded the lowest values in all previous characters for both crops. Hamdany and El-Aassar (2017) reported that root diameter, root fresh weight, top fresh weight, root yield fed -1 , top yield fed -1 , TSS and sucrose% were significantly increased by reduced faba bean plant densities from 37.5% to 12.5%, except root length and purity % were decreased.…”
