The influence of sprinkler irrigation and four nitrogen fertilization doses on the height of true millet cv. ‘Gierczyckie’ was determined in a field experiment carried out in the years 2005–2006 on a very light soil at Kruszyn Krajeński near Bydgoszcz. The soil in horizon 0–50 cm was characterized by field water capacity 57 mm, useful retention 43 mm and effective useful retention 30 mm only. The experiments were run in a split-plot system with three replications. Two different factors were compared. The first row factor – irrigation, was used in the two following treatments: Wo – without irrigation (control), W1 – sprinkler irrigation according to tensiometer indications (-0,03 MPa). The second row factor – differentiated nitrogen fertilization, was used in the four following variants (doses): N0 = 0 kg N ha -1, N1 = 40 kg N ha -1, N2 = 80 kg N ha -1, N3 = 120 kg N ha -1. Water requirements of true millet were estimated as optimal rainfall amounts for this crop, according to Klatt and Press proposals. Mean - for two seasons - water needs of true millet (since May 1 to August 31) amounted 278 and 294 mm, for Klatt and Press proposals, ...
The influence of sprinkler irrigation and four nitrogen fertilization doses on the height of true millet cv. ‘Gierczyckie’ was determined in a field experiment carried out in the years 2005–2006 on a very light soil at Kruszyn Krajeński near Bydgoszcz. The experiments were run as a two-factorial trial in a split-plot system with three replications. The first row factor – irrigation, was used in the two fol-lowing treatments: without irrigation (control), sprinkler irrigation according to tensiometer indications (-0,03 MPa). The second row factor – differentiated nitro-gen fertilization, was used in the four following variants (doses): 0, 40, 80 and 120 kg N•ha-1. Investigations included estimation of infestation degree: roots with complex of pathogens, stem base with Fusarium spp., Oculimacula spp. and Rhizoctonia spp. On leaves was observed the occurrence of: powdery mildew, Phyllosticta leaf blight, and other necrotic spots. Irrigation caused the significant increase of Fusarium foot rot as well as the decrease of sharp eyespot. Health status of non-irrigated true millet was de-pendent mostly on rainfall. Lower intensity of Fusarium foot rot was noted in the year characterized by lower rainfall amounts during the vegetation period of true millet, but in case of sharp eyespot – in the year ...
The aim of the study conducted in the years 2005-2006 was to determine the influence of sprinkler irrigation and four nitrogen fertilization doses (0, 40, 80, 120 kg N•ha-1) on health status of true millet cv. ‘Jagna' cultivated on a very light soil. Investigations covered estimation of infestation degree with: complex of pathogens on roots and in the case of stem base - Oculimacula spp., Rhizoctonia spp., Fusarium spp. and Bipolaris sorokiniana. On leaves there was observed the intensity of Phyllosticta leaf blight and other necrotic spots. Irrigation caused the significant increase of root rot and stem base infesta-tion with Fusarium spp. and B. sorokiniana. Health status of non-irrigated true millet was dependent mostly on rainfall. Lower intensity of most diseases was noted in the year characterized by lower rainfall amounts during the vegetation period of millet. The higher nitrogen dose resulted in the significant increase of infestation of millet roots and stem base with Oculimacula spp. The pathogenic fungi occurring on infected millet roots were mostly represented by Fusarium spp., especially F. solani, F. oxysporum and F. equiseti. Stem bases showed the occurrence of F. equiseti and B. sorokiniana. Presence of R. cerealis and R. solani in the ...
