Abstract

A field experiment was conducted at Hama Research Station, General Commission for Scientific Agriculture Research (GCSAR), during 2016/2017 and 2017/2018 seasons, to compare production, quality and morphological characteristics of monogerm fodder beet variety, i.e. Jamon under four levels of nitrogen fertilizer (20, 80, 120 and 180 pure units of N, urea 46%/ha). The experiment was sown in summer during September. A randomized complete block design (RCBD) was used with three replications. The statistical analysis of both seasons exhibited a significant effect of the nitrogen fertilizer (N) on all of the production traits (shoot yield (ton/ha)) and morphological traits (shoot weight per plant (g), and root length and diameter (cm)). Also, there were no significant differences in quality traits (dry matter in root and shoot (%) and sucrose (%)). The least significant difference test (LDS0.05) showed the possibility of adding 80 pure units of Urea/ha to get the best production, quality and morphological traits.

Key words: Fodder beet, Nitrogen fertilizer, Production traits, Quality traits, Morphological traits.

Abstract

The research was conducted during 2017season at a field in Talkalakh region in Western Area of Homs governorate. The research objectives were to study the effect of spraying humic acids 2.5cm3/l and adding nitrogen fertilizer on growth and productivity of maize variety (Gouta82). Three treatments of humic acids were used: control, one time of spraying after 15 days of planting and two times of spraying humic acids (the first one after 15 days of planting while the second one after 30 days of planting). Four levels of nitrogen fertilizer were used i.e. 0,60,90 and 120 kgN/ha. Spilt – plot design with three replications was applied. Humic acids treatment were allocated in the main plots but nitrogen fertilizer treatments were represented in the sub plots. Results showed that increasing number of spraying humic acids to two times caused an increase in: number of leaves per plant, leaf area index, plant height, ear characters, grain yield and its components. Also, increasing nitrogen fertilizer levels caused an increase in: number of leaves per plant, leaf area index, plant height, ear characters, grain yield and its components. Spraying humic acids two times and adding 120 kgN/ha  gave the highest grain yield (7229.25) kg/ha.

Key words: Zea maize, Humic acids, Nitrogen fertilizer, Grain yield.
