Sažetak

Crni muhar se gaji u sredinama koje su pogođena sušom. Očekuje se da će klimatske promene povećati osetljivost u svim agro-ekološkim zonama, kroz rastuće temperature i obilne padavine, što će imati drastične posledice na prehrambenu sigurnost. Crni muhar je žito koje ima veliki potencijal za obezbeđenje prehrambene sigurnosti i stvaranje prihoda na marginalnim područjima, zbog svoje pogodnosti gajenja i u ekstremnim uslovima poljoprivrede. Ovo studija je izvršena na eksperimentalnom lokalitetu Jebel Kordofan, u pokrajini Sheikan u državi Severni Kordofan tokom sezona 2010-2012. godine, kako bi se procenio uticaj različitih tehnika setve i padavina na produktivnost prinosa lokalnih i poboljšanih sorti prosa. Tretmani predstavljaju kombinaciju četiri tehnike setve i dve sorte crnog muhara. Tehnike setve su uključivale: suvu setvu, vlažnu setvu, duboku sadnju (na dubini od 10 cm) i potapanje sa mikrodoziranim đubrivom. Dve sorte su bile uključene: Ashana (poboljšana) i Dembi (lokalna). Ovi tretmani su bili raspoređeni po dizajnu podeljenih parcela, glavna parcela za sorte i potparcela za metode setve u četiri ponavljanja. Proučavani su parametri: dani do 50% cvetanja, visina biljke (cm), prinos zrna (kg/ha) i produktivnost padavina (kg/ha/mm). Sorte su pokazale visoko značajne razlike u odnosu na broj dana do 50% cvetanja, visinu biljke (cm), prinos zrna (kg/ha) i produktivnost padavina (kg/ha/mm). Tehnika suve setve značajno (P ≤ 0.05) je dala je najviše biljke (149cm), veću efikasnost korišćenja vode (5, 10 kg/ha/mm) i najviši prinos zrna (1637 kg/ha). Može se zaključiti da je setvena parcela pripremljena čizel plugom i setva u suvom zemljištu dala najviši prinos zrna.
