Effect of Plant Population and Distribution on Yield and Yield Components of Five Faba Bean Genotypes

Abstract

Plant population density plays an important role on crop growth and yield as response to light penetration and photosynthesis rate. A field experiment was carried out at Sids Research Station, Agricultural Research Center (ARC), during two successive winter seasons, of 2012/13 and 2013/14. The objectives of this investigation was aimed to evaluate five faba bean genotypes namely Nubaria 1(large seeded cultivar), Giza 429, line 43130, E.19 (medium seeded types) in addition to the small seeded type Camolina. Plant densities were; a) 8 plants/m 2 planted in single seeded hills spaced 20 cm on one side of 60 cm wide ridges, b) 17 plants/m 2 planted in double seeded hills spaced 20 cm on one side of the ridges, c) 17 plants/m 2 planted in single seeded hills spaced 20 cm on both sides of the ridges and d) 33 plants/m 2 planted in double seeded hills spaced 20 cm on both sides of the ridges. Results indicated that, faba bean genotypes were significantly different in all studied characters. Nubaria 1 and E.19 genotypes had the tallest plants, respectively. The highest seed yield per feddan was obtained from Nubaria 1 cultivar, while the medium seeded line L-43130 produced the lowest seed yield per feddan over both seasons. Giza 429 (medium seeded cultivar) followed by Nubaria 1. Plant population of 17 plants/m 2 in single seeded hills on both sides of the ridges produced highest seed yield per feddan over all genotypes. Concerning to the interaction between plant populations and faba bean genotypes, highest seed yield per feddan was obtained from the large seeded cultivar Nubaria 1 under the low plant population (8 plants/m 2 ), while the medium seeded types i.e. Giza 429, L-43130 and E19 were more yielding under the third plant population (17 plants/m 2 on both sides of the ridge). On the other hand, the small seed type Camolina produced highest seed yield per feddan under the high plant population (33 plants/m 2 ). The interaction between faba bean genotypes and plant population had significant effects on all studied characters except number of days to flowering.

Influence of Plant Population and Weed Control Treatments on Associated Weeds, Growth, Yield and Quality of Faba Bean

“…However, the highest seed yield/fed resulted from sowing faba bean at plant population 120000 plants/fed which exhibited increments of seed yield by 18.30 and 5.30% in the first season as well as 19.53 and 8.51 % in the second season than that of 80000 and 96000 plants/fed, respectively (Table 3). These results are in agreement with thus reported by El-Hindi et al, 2008 andAbd El-Rahman, 2014). Narrow ridges spacing may increase crop access to available soil moisture because of the more equidistant distribution of crop plants and increases light interception by the crop, particularly in the early growing season, thereby leading to increased crop growth rates and earlier canopy closure, Dalley et al (2004).…”

“…Consequently, a greater photosynthetic photon flux density interception with a lower weed aboveground dry matter were recorded with narrow row arrangement. Similar results were reported by (Farghaly, 2002;El-Hindi et al, 2008 andAbd El-Rahman, 2014) The results presented in Table 1 clearly showed that the dry weights of broadleaved, grassy and total weeds were significantly reduced due to studied weed control treatments as compared with the unweeded check. Two hand hoeing method recorded the highest weed depression expressed in the lowest dry matter of the mentioned weed groups.…”

“…Particularly, Turco et al (2016) found that faba bean seeds contain several other bioactive compounds, such as polyphenols. However, the effect of faba bean plant density on growth, yield and its attributes was studied by Bakry et al (2011), Khalil et al (2011) and Abd El-Rahman (2014). Growing faba bean in two sides per row produced higher seed yield per unit area than one side per row (Abou-El-Seba et al 2016).…”
