Investigations were carried out in the experimental ields of Lithuanian Institute of Horticulture in 2009-2010. Soil--calcaric epihypogleyic luvisol of sandy loam on light loam soil IDg8-k (Calc(ar)i--Epihypogleyc Luvisols--LVg-p-w-cc). Arable layer was 20-25 cm in thickness. Carrot cultivar 'Svalia' F1 was grown in furrowed surface. Sowing scheme 62 + 8 cm. There was investigated the influence of Naturcomplet®--G fertilizer rates on carrot yield and quality. Applying fertilizer Naturcomplet®-- G (rate--70 kg ha-1 ) there was obtained the biggest density and total yield of carrot crop. Naturcomplet®--G fertilizer rates didn't inluenced more signiicantly the average carrot root-crop diameter and weight, but applying 80 kg ha-1 of Naturcomplet®--G carrot root-crops were on the average 1.9 mm longer then this of not fertilized ones. The biggest addition of marketable yield and the output of marketable yield were obtained fertilizing carrots with 80 kg ha of Naturcomplet®--G. [ABSTRACT FROM AUTHOR]

Investigations were carried out at the Lithuanian Institute of Horticulture, in calcaric epihypogleyic luvisol of sandy loam on light loam soil (IDg8-k / Calc(ar)i- Epihypogleyc Luvisols - LVg-p-w-cc), in 2005-2007. Ploughing layer of the soil was 20-25 cm in thickness. Onion cv. 'Babtų didieji' was grown on flat surface. Sowing scheme - 62 + 8 cm. There was investigated the influence of humistar applied before sowing rates on onion productivity and its indices, humus quality changes in the soil and there was evaluated the interaction and the influence of environmental factors on these factors. The biggest onion total (24.2 t ha-1) and standard (19.2 t ha-1) yield was obtained fertilizing with humistar rate of 20 l ha-1. Standard yield output was 79.7 %. Applying this humistar rate there was the biggest crop density, turnip weight and its diameter, and the relation of humic acids in onion crop was 0.29. The increase of crop density (r = 0.64; 23 %), precipitation amount during vegetation in the investigation period (r = 0.48; 18 %), turnip weight (r = 0.34; 12 %) and the amount of humic acids in the soil (r = 0.30; 11 %) increased onion standard yield. The influence of the increase of fulvic acids (r = - 0.34; 12 %) and temperature (r = - 0.48; 18 %) was weak, but negative. [ABSTRACT FROM AUTHOR]
