Sažetak
Poljski ogled je sproveden na eksperimentalnom polju Nacionalnog instituta za istraživanja u hortikulturi u Ibadanu u Nigeriji krajem kišne sezone 2015. godine kako bi se odredio odgovarajući sistem gajenja zasnovan na bamiji i leguminozama koji će povećati prinos useva i prihod poljoprivrednika. Ogled je organizovan po slučajnom blok dizajnu (engl. randomized complete block design - RCBD) sa tri (3) ponavljanja. Tretmani su obuhvatali združenu setvu bamije sa kikirikijem ili vignom sejanih na različitim rastojanjima (60 cm x 30 cm, 60 cm x 40 cm, 60 cm x 50 cm i 60 cm x 60 cm). Bamija je sejana na rastojanju od 60 cm x 40 cm, a veličina parcele bila je 3 m x 2,4 m (7,4 m2). Prikupljeni podaci su podvrgnuti analizi varijanse (ANOVA), i značajne srednje vrednosti su odvojene korišćenjem testa najmanje značajne razlike (engl. least significant difference [LSD] test) na nivou verovatnoće of 5%. Ekonomska analiza združivanja useva sprovedena je korišćenjem analize bruto marže, indeksa monetarne prednosti i analize odnosa primanja i troškova. Rezultati su pokazali da je LER indeks (engl. land equivalent ratio - LER) od 1,62 zabeležen u združenom usevu bamija/kikiriki na rastojanju od 60 cm x 40 cm, dok je LER indeks od 1,74 uočen u združenom usevu bamija/vigna na rastojanju od 60 cm x 30 cm. Združeni sistem bamija/vigna na rastojanju od 60 cm x 30 cm bio je najunosniji (₦859.192/ha), zatim je sledio združeni usev bamija/vigna sa rastojanjem od 60 cm x 50 cm (₦744.212/ha), dok je združeni usev bamija/vigna na rastojanju od 60 cm x 60 cm bio najmanje unosan. Najviša bruto marža od ₦2.188.961/ha postignuta je u združenom usevu bamija/kikiriki na rastojanju od 60 cm x 40 cm. Najmanji prihod je ostvaren kod združenog useva bamija/kikiriki na rastojanju od 60 cm x 60 cm (₦700.103/ha). Ekonomska analiza je pokazala da je kod združenog useva bamija/vigna pri rastojanju od 60 cm x 30 cm postignuta najviša bruto marža od ₦859.192/ha i indeks monetarne prednosti od ₦450.447/ha, dok je u zdrženom usevu bamija/kikiriki na rastojanju od 60 cm x 40 cm ostvarena najviša bruto marža od ₦2.188.961/ha i indeks monetarne prednosti od ₦924.642/ha.
