Land Productivity of Root Crop Farmers amidst Pesticide Application in Southeast, Nigeria: Land Productivity of Root Crop Farmers | Produktivnost kmetov pridelovalcev korenovk in gomoljnic ter uporaba pesticidov v jugozahodni Nigeriji: Land Productivity of Root Crop Farmers

英语. The study evaluated the land productivity of root crop farmers amidst pesticide application in southeast, Nigeria. 358 root crop producers were chosen using a multi-stage sample and given a questionnaire. The analysis of the data included the use of mean, frequency, percentage, total factor and partial factor productivity, analysis of variance, multiple regression model, and local average treatment effect (LATE). Data were acquired using primary means. The results show that root crop growers were mostly women (76.9%), married (85.1%), educated (mean=12.0), and in their prime working age (51). Estimates of total factor productivity (TFP) and partial factor productivity (PFP) gave 7.69 and 177.25, which indicates higher land productivity values across Imo, Abia, and Ebonyi State. Education, access to farm inputs, soil/land improvement practices, size of farm, and extension relations were important components of land productivity across the States. Use and application of pesticides according to specified recommendation increased land productivity by (727.07%) and (880.28%). Erosion problems (99.7%), pests and disease (96.9%), high cost of inputs (99.1%), climate change (99.4) and land fragmentation (93.0%) constrained land productivity in the States. Study recommends farmers to practice more of land improvement practices and adhere to specified pesticide use and application to increase land productivity

斯洛文尼亚语. V raziskavi sta bili ovrednoteni produktivnost kmetov, ki pridelujejo gomoljnice in korenovke ter uporaba pesticidov v jugozahodni Nigerijio. Izbran je bil vzorec 358 pridelovalcev v večstopenjskem procesu vzorčenja. Informacije o predmetih raziskave so bile pridoblljene s primarnimi postopki. Analiza podatkov je vsebovala uporabo poprečij, frekvenčne in odstotkovne analize delne in skupne  faktorske  produktivnosti, analizo variance, multipli regresijski model in učinek poprečja lokalne pridelave (LATE). Rezultati kažejo, da so pridelovalci teh poljščin pretežno ženske (76,9 %), ki so poročene (85,1 %), izobražene (poprečje = 12,0), z najpogostejšo starostjo 51 let. Izračuna produktivnosti glede na vse (TFP) in posamezne dejavnike (PFP) sta znašala 7,69 in 177,25, kar kaže na večjo produktivnost zemljišč v državah Imo, Abia in Ebonyi. Izobrazba, dostop do pomoči kmetijam, izboljšane tehnike obdelave tal, velikost kmetij in obiski kmetijskih svetovalcev so bili značilni določevalci produktivnosti zemljišč na 1 % in 5 % ravni. Uporaba pesticidov glede na priporočila je povečala produktivnost zemljišč za 727,07 % in 880,28 %. Problemi z erozijo(99,7 %), s škodljivci in boleznimi (96,9 %), velikimi stroški pridelave (99, 1 %), s klimatskimi spremembami (99, 4 %) in razdrobljenostjo zemljišč (93,0 %) so omejevali produktivnost v vseh državah. Raziskava priporoča kmetom, da uporabljajo boljše načine obdelave tal
