Late Sowing

Quality parameters of 5 table root varieties were tested on 3 sowing dates with different cultivation methods: open field on 15 April and 9 July 2010 and under plastic tents on 19 August. The highest red pigment content (betanin) was measured in the varieties Akela and Mona Lisa (~ 80 mg 100 g-1) of the second (July) crop. This crop is in general use in Hungary. In comparison, in the late sown varieties (August, under plastics) a further pigment increase (10–20 mg 100 g-1) was observed in the same varieties as related to the earlier sowing dates. Yellow pigments (vulgaxanthins) showed similar trends. Roots of the late sowing date (with harvest in December) contained the highest vulgaxanthin values (103.3–124.18 mg kg-1).Varieties reacted differently to temperature changes during the production period and thus to sugar accumulation. In the second crop (July) higher water soluble solids content was measured on the average of varieties (10.12%) in comparison to the April sowing (7.76%). Beetroots of the spring sowing are recommended for fresh market while the second (July) crop with autumn harvest can satisfy industry requirements. Late sowing under unheated plastic tents supply us with fresh beetroot in late autumn and early winter and prolong the usability of plastic tents. Six lettuce species/subspecies were tested in the open field and under plastic tents in 3 repetitions for nitrate nitrogen, vitamin-C, polyphenol (gallus acid equivalent – mg GAE 100 g-1) and mineral element (Ca, K, Mg, Na) contents. Our measurements showed lower nitrate nitrogen values under plastic than in the open field (89.10± 8.13 and 127.06±14.29 mg kg-1) on the average of genotypes. Lettuce grown in the field had higher vitamin-C content (1.4 mg%) which is nearly 50% more than in plants under plastic. The highest polyphenol content was found in samples from the field with a conspicuous value of 804.17±56.47 mg GAE 100 g-1 in Piros cikória. Samples grown under plastic were richer in mineral elements (Ca, K, Mg, Na) which can be explained by the higher nutrient content of the soil. In this environment superior Mg content was observed in Edivia (4616.33±311.21 mg kg-1).  Besides the well- known headed lettuce, Piros cikória (Red chicory),the red leaved Lollo Rossa and Tölgylevel (Oak leaf lettuce) should bementioned which well deserve further testing in order to supply us with nourishing, healthy food.

The results of studying resistance of mid-ripening spring wheat cultivars to root rot in the forest-steppe zone of Irkutsk region are presented. The study was conducted in a two-factor field experiment. Factor A – mid-ripening spring wheat cultivars: Tulunskaya 11 (control), Zoryana, Маrsianka, Stolypinka (new cultivars). Factor B – seeding dates: May 10, 20, 30, preceded by fallow. The experimental plot area was 70.0 m2. The experiment was repeated three times. Plot arrangement was randomized. Root rot prevalence was determined during the tillering phase of the crop. In 2018, the sowing dates did not affect the disease due to the long spring-summer drought (May-June) and a higher average daily temperature compared to long-term average values. In arid and cold conditions of May 2019, with the late sowing period (May 30), root rot prevalence was significantly lower than when sowing on May 10 and 20. In 2019, a higher level of the disease was registered than in 2018 by 14.3%. Significant differences in root rot prevalence in both years of research were noted between the control cultivar Tulunskaya 11 and the new cultivars of spring wheat Zoryana and Stolypinka. In the tillering phase of the latter two, disease indicators were lower by 5.6% and 10.5% in 2018, and by 8.8% and 7.9% in 2019, respectively. Маrsianka cultivar was at the control level for this indicator. The best cultivar under study was Stolypinka, which was not only less affected by root rot, but also gave a statistically significant yield increase of 0.16 t/ ha in 2018 and 0.22 t/ha in 2019.

Plot Design

An experiment was carried at Multi Location Testing site Barguna to determine suitable variety of mustard (Brassica species) for the late sowing condition for the coastal area of Bangladesh during rabi season of 1998-1999 and 1999-2000. Four varieties of mustard such as Daulat, Rai-5, Improved tory-7, and Ishurdi local with four sowing dates viz.15 Nov, 23 Nov, 30 Nov. and 7 Dec. were used for the experiment. The experiment was laid out in a split plot design with sowing date in the main plot and varieties in the sub plot. The results revealed that the variety Daulat (1035 kg/ha) and Ishurdi local (1014 kg/ha) produced identically superior yield irrespective of sowing time. 15 November (1164 kg/ha) and 23 November (1002 kg/ha) recorded identically superior yield irrespect of variety. Daulat and Ishurdi local variety sowing could be delayed up to 30 November to obtain a profitable yield of (872 kg/ha) and (940 kg/ha) respectively which was still economically profitable.

Late Sowing

Seven genotypes, including 5 in the final stages of cultivar selection, were evaluated for their phenological development, yield, seed size, oil concentration and protein concentration in response to changes in sowing date and row spacing over 3 seasons, 1982-83, 1983-84and 1984-85. Genotype x sowing date interactions were detected for both phenological development and yield, particularly with the cultivar Sxy 59. This genotype was most affected by temperature during the pre-flowering phase of early November sowings. It was lower yielding in November sowings but was the highest yielding genotype in January sowings. Its adaptation to January sowings was unexpected because this genotype also showed high photoperiod sensitivity and flowered and matured rapidly in the late sowings. With early sowing, yield of the other cultivars was equivalent, or superior to (P=0.05), that obtained with the recommended early December sowing date, depending on the season. Late sowings caused yield reductions of about 34%. Increases in yield with narrow rows (50 v. 100 cm) were significant (P = 0.05) in 1 season and averaged 5% overall. Genotypexrow spacing interactions were only detected in 1 season, but no genotype was superior to the standard cultivar, Forrest, in adaptation to narrow rows. Thus this study revealed genotype responses which would affect adoption of newly released cultivars. It was concluded that this type of study is valuable in the final stages of a selection program and that these studies should include both early and late sowing dates and be conducted over several seasons.

Late Sowing

The yield, protein and starch content of Martonvásár maize hybrids belonging to different FAO groups were examined in experiments involving early, optimal and late sowing dates in two different years (drought — 2007, favourable water supplies — 2008) on a calcareous chernozem soil with loam texture at the Látókép Experimental Station of the Centre of Agricultural Sciences and Engineering, University of Debrecen.Sowing date had a significant effect on maize grain yield in the dry year. The grain yields of hybrids with longer growing periods were significantly higher than those with shorter growing periods in both years, but they reacted sensitively to the change in sowing date in the dry year. Due to the rainfall distribution in the growing season, sowing date did not modify the performance of the hybrids in the year with favourable water supplies. Sowing date had a significant effect on the grain protein content in the dry year, with significantly higher values after late sowing than after early or optimal sowing. Averaged over the sowing dates, the protein content of the FAO 200 hybrid was significantly higher in both years than that of hybrids in other FAO groups. In the dry year, the greatest difference in protein content could be observed between the early and late sowing dates for hybrids in all four FAO groups. A negative correlation was found between yield and protein content. Sowing date significantly increased the starch content of maize in the favourable year, with a significant difference between early and late sowing dates.In the dry year higher starch contents were recorded for all the hybrids and for all the sowing dates than in the favourable year. In the dry year, sowing date only caused a significant difference in the starch content in the case of FAO 200 sown at optimal and late sowing dates. In the favourable year, a significant difference was only obtained for the starch content of the FAO 400 hybrid sown at early and late sowing dates. Satisfactory quality can only be achieved if suitable genotypes are grown with appropriate technologies.
