Abstract: There is renewed interest in white lupine (Lupinus albus L.), which is appreciated for its high protein content, full range of essential amino acids and as N source to rainfed cropping systems. Unfortunately, information on its N 2 fixation ability is limited. This study aimed to: (i) quantify the N 2 fixation ability of white lupine crop at the plot field scale in three different environments of Sardinia (Italy)

“…Total soil N is associated with SOC and plays a key role in building soil fertility and enhancing soil productivity. Francaviglia et al (2014) total soil N levels were highly correlated and previous studies carried out in Sardinia highlighted the positive input of N-fixation as soil N source (Sulas et al, , 2016. Therefore, the amounts of fixed N estimated from this study are presumably able to positively affect total soil N and consequently SOC, taken into account the conservative contest associated with the sulla crop.…”

“…Based on experience and judgment, 48% and 46% of the farmers rated nitrogen fixing capacity of lupin as good and very good, respectively, whereas both faba bean and field pea were rated as good by 42% and 37% of the farmers (Figure 2). This result is in-line with earlier reports that lupin can potentially fix and accumulate a total of 150 to 400 kg/ha nitrogen per year, while faba bean fixes up to 200 kg/ha per year (Jansen, 2006;Sulas et al, 2016). More than 85% of the respondent farmers mentioned that lupin require minimal inputs, whereas about 50% of the respondents mentioned that field pea requires moderate level of input and 60% of the respondents mentioned that faba bean requires more inputs than lupin (Figure 2).…”

“…Again, the flour from tarwi (legume grain) shows a very different composition, with a protein content similar to those reported by Villacrés, et al [29] in samples of debittered tarwi from Ecuador (54.05%), and much higher than that found in tarwi flour from Egypt (43.17%) [16]. The higher protein content compared with the other crops analyzed is due to its leguminous nature, with a high nitrogen fixation capacity [30]. A high protein content represents an alternative for the development of enriched foods with a different source of protein or to balance protein-deficient flour blends, also conferring texture to the flour.…”
