Effect of the 'Bebizea' stimulant on maize yields with and without irrigation

Abstract

During 2002-2003, field trials were carried at the Rirnski Šančevi Experiment Field of the Institute of Field and Vegetable Crops in Novi Sad to study the effects of the "Bebizea" stimulant preparation on yield and yield components of eight NS maize hybrids from different FAO maturity groups in irrigated and unirrigated conditions. Seed treatment by the preparation had no statistically significant positive effect on yield, 1000-grain weight, grain moisture and cob percentage contribution, although in some of the hybrids these parameters were affected to a certain, insignificant extent. As a result of irrigation, the yield stabilized at a high level regardless of whether or not the maize had been treated with "Bebizea". Over the two study years, the increase of yield by irrigation averaged 34.88%.

U cilju ispitivanja uticaja stimulativnog preparata "Bebizea" na prinos i elemente prinosa na oglednom polju Rimski Šančevi Naučnog instituta za ratarstvo i povrtarstvo Novi Sad u periodu od 2002-2003- godine izvedeni su poljski ogledi sa 8 NS-hibrida kukuruza različitih FAO grupa zrenja u uslovima sa i bez navodnjavanja. Tretiranje kukuruza preparatom "Bebizea" nije imalo statistički značajno pozitivan efekat na prinos, masu 1000 zrna vlažnost zrna, masu klipa i udeo kočanke, mada je kod jednog broja NS hibrida beznačajno uticao na pomenute parametre. Navodnjavanjem je stabilizovan prinos kukuruza na visokom nivou bez obzira da li je kukuruz tretiran ili ne preparatom "Bebizea". Prosečno povećanje prinosa u ispitivanom periodu u navodnjavanju iznosio je 34,88%.
