AB  - Weeds are among main limiting factors in sweet maize production. Commercially grown sweet corn hybrids (Zea mays saccharata Sturt.) vary widely in competitive ability against weeds which interference differentially affects yield and ear traits important to processing and fresh markets. A total of 28 sweet corn hybrids of different FAO maturity groups have been developed at the Maize Research Institute, Zemun Polje, and released by the the Commission for the Variety Releasing. In order to obtain high yields of good quality the scientists have been searching for the most appropriate growing practices. Therefore the objective of the present study was to determine the effect of four plant densities (40 000, 50 000, 60 000, and 70 000 plants/ha) on the level of weed infestation, yield and shelling percentage of four sweet maize hybrids (ZP 424su, ZP 462su, ZP 504su, and ZP 521su) in 2008 and 2009. Total fresh weight and the total number of weeds decreased with increasing sowing density, which was more prominent in 2008. Results of the analysis of variance showed that investigated factors, year, sowing density and hybrid had significant influence on fresh ear yield and shelling percentage. Sowing density affected fresh ear yield in the way that the denser sowing was, the higher yield was. Hybrids ZP 424su and ZP 462su gave higher fresh ear yields than other two. However, hybrids with less fresh ear yield (ZP 504su and ZP 521su) gave better shelling percentage. These results suggest that ZP 424su and ZP 462su can be preferable for fresh consumption and ZP 504su and ZP 521su for processing.

AB  - Adoption and improvement of different tillage systems toward agricultural sustainability has a great social, economical and environmental impact. The base of sustainability is a system productivity as ratio of output to input in a given system, measured in the same units, commonly as energy requirements. The objective of this study was to evaluate the aspect of energy requirements in the different soil tillage systems regarding total energy consumption under conventional tillage. The appropriate measuring at the field conditions, conducted during the period of investigation 1998-2010 on the soil type of slightly calcareous Chernozem. Maize crop was grown under typical Balkan two-crop rotation with winter wheat. Grain yield of maize and energy efficiency were fallowed on the different tillage systems: conventional tillage (CTS - summer tillage of stubble + deep autumn plowing + pre-sowing preparation); reduced tillage (RTS - heavy disc harrowing ); and no-tillage (NT - direct sowing into wheat stubble covered with all amounts of straw residues using no-till planter John Deer Max emerge 2 with the double disc openers). Results of examination have indicated high energy efficiency of No tillage Systems (NTS). Besides statistically lower yields being recorded comparing to a conventional tillage, good results with No-till system have actualizing necessity to continue research on new growing technology and to improve its implementation. .

AB  - The effects of three tillage systems (conventional and two conservation systems) on the grain yield of the maize hybrid ZPSC 704 were observed in the present study. The two-year (2006 and 2007) trail was set up on chernozem in experimental plots of the Maize Research Institute, Zemun Polje, in Belgrade-Zemun. 
	Maize growing practices that included the conservation tillage system with the chisel plough and different rates of mineral fertilisers provided, especially in 2006, the grain yield at the level of the yield gained by the conventional tillage system that included the conventional plough. The lowest maize grain yields in both investigated years in both watering regimes were obtained under the no-tillage system.   
The mineral fertiliser application and a consequent plant nutrition showed a certain  regularity in relation to the watering regimes. Namely, the highest average maize grain yields were obtained under rainfed conditions with a poorer nutrition, while the lowest yields were gained under irrigation regimes also with a poorer nutrition.
