Zaradi prakticiranja odloga spravila pridelka manioke, kadar se pojavlja njen višek na trgu in pojavljanja uničujoče gnilobe gomoljev, se je pojavila potreba po ovrednotenju elitnih sort te tropske gomoljevke, gojene v medsadnji. Poskus je bil izveden na Federal University of Agriculture, Abeokuta med 2011 in 2014 z namenom ovrednotenja pridelka 21 elitnih sort manioke, posajene v monokulturi ali v kombinaciji z drugimi kulturami in pospravljene v različnih časovnih obdobjih. Faktorski 2 × 21 × 3 poskus je bil izveden po sistemu naključnih blokov s tremi ponovitvami. Pridelek gomoljev na površinah z monokulturo je bil v rastni sezoni 2011/2012 značilno večji kot na površinah z medsadnjo, v rastni sezoni 2012/2014 pa sta bila pridelka podobna. Ekvivalent zemljišča je bil nad ena v obeh rastnih sezonah in kaže prednost izboljšanih sort, gojenih v medsadnji. Analiza povprečnih vrednosti pridelka gomoljev je pokazala, da so bile sorte TMS 30572, 92/0326, 95/0211, 01/1371, 00/0338, 01/0046, 00/0098, 01/1097, 01/0085, 98/0581 in 98/510 med osmimi najdonosnejšimi. Za zmanjšanje gnilobe je izkop gomoljev lahko zamaknjen do 15 mesecev po sadnji.
