“…Moreover, Donald [19] found that as the number of plants per unit area increased competition for growth resources such as nutrients, water and light also increased. Similar results were reported by others researches [20,21,22,23].…”

“…However, Papastylianou (1995) showed that peanut yield was unaffected by further increasing plant density per unit area. Conversely, several researchers have reported that peanut pod yield was higher in high plant density than grown in low plant density (Lanier et al, 2004;Sorensen et al, 2005;Ahmad et al, 2007;Rasekh et al, 2010 andKonlan et al, 2013). The present study was therefore conducted to increase pods and oil yields, as well as, net return.…”

“…This was a result of the larger shoot dry matter yields and the corresponding greater shoot N accumulated by sole crops (Table 2.3), as the amount of N2-fixed greatly depends on shoot dry matter yield (Giller, 2001) and the accumulated shoot N (Peoples et al, 2009). Also, Konlan et al (2015) reported a greater N2-fixation in sole groundnut than in groundnut intercropped with maize in the Guinea savanna of northern Ghana. Yet when the shoot dry matter yields were poor, such as in the SGS where cowpea yields were relatively smaller and groundnut which had poorer yields at both sites, the amount of N2-fixed was similar between sole crops and intercrops.…”

“…Only few studies (e.g. Eaglesham et al, 1981;Konlan et al, 2015) assessed the effect of maize-grain legume intercropping on N2-fixation. Even so, the net N contributions to the soil from the intercrop systems were not measured.…”
