The results of the assessment of potato varieties of foreign and local selection in the conditions of Yakutia, carried out in 2012– 2014, are presented. (the characteristic of weather conditions is presented). All varieties belong to the group of early maturing and mid-early. The best in terms of yield in 2012 were the varieties Tulunsky Early (14.8 t / ha), Kamensky (13.7) t / ha and Varmas (13.5 t / ha). The local variety Yakutyanka exceeded the distinguished varieties in yield by 3.9–5.2 t / ha. by the number of tubers from the bush, the varieties Tulunsky early and Yakutyanka were distinguished. The marketable yield of all varieties in 2013 ranged from 10.5 t / ha (Kolobok variety) to 28.8 t / ha (Yakutyanka variety). The marketable yield in 2014 averaged 15.6 t / ha, while Kamensky (18.6 t / ha) and Yakutyanka (18.8 t / ha) cultivars formed a higher yield. In 2012, for all varieties, the marketability varied within 60-75%. The highest marketability of the crop was noted for the Yakutyanka variety - 75%. The marketability of tubers in potato varieties was different in 2013. The highest marketability of the crop was noted for the Varmas variety (98%), the lowest was noted for the Severny and Briz varieties, the marketability was 77–78%. In 2014, the marketability for all varieties varied within 74–95%. The marketable yield of the Yakutyanka variety was the highest in comparison with other varieties and amounted to 18.8 t / ha. Analysis of the ecological plasticity of potato varieties in terms of yield revealed the most plastic variety of the adaptive type Yakutyanka, which in various weather conditions forms a yield of at least 14.0 t / ha.

Variety Testing

The aim of the research is to breed short climbing, early maturing, high-yielding varieties of squash in the natural and climatic zone of Uzbekistan.Methods. The samples of squash 0044SQ (Holland) and BT+KB-001 (Turkey) were taken from the gene pool of the Research Institute of Plant Industry (Uzbekistan) in 2012 for breeding work. In 2013, squash samples were studied in the nursery of the source material, where they were evaluated for biological and economically valuable traits. Individual selection of plants was carried out. In further breeding work (2014-2016 and 2018), the lines LZ-2513 and LH-1916 were distinguished.Results. The method of analytical breeding created short-climbing, early maturing, high-yielding of squash lines LZ-2513 and LH-1916. Line LZ-2513 has rounded fruits of light green color. The LH-1916 variety has elongated, dark green fruits. Competitive variety trials of new lines were conducted in 2019-2020. Unumdor variety zoned in the republic served as a standard. It was found that from sprouting to maturity of the fruit in the line LZ-2513 is 44 days, in the line LH-1916 – 45 days. High marketable yield was recorded for squash line LZ-2513 – 18.3 tons/ha (122% of the standard); in line LH-1916 marketable yield was 16.4 tons/ha (112.4% of the standard). This year we organized the primary seed production of squash lines LZ-2513 and LH-1916 for multiplication.Conclusion. Promising for cultivation in conditions of Uzbekistan squash line LZ-2513 Orbita (NAP 20200087) and line LH-1916 Viridi (NAP 20200088) were submitted to the Intellectual Property Agency under the Ministry of Justice of the Republic of Uzbekistan to be patented.

Experiments were conducted in field plots to evaluate the effects of three alternative dried organic, or organomineral, fertilizers on yield and quality of the early maturing cauliflower variety, ‘Gameta’. Plots were established in Žabčice (South Moravia, Czech Republic) in 2005–2007. We used the following fertilization treatments: Agormin T, Agro, Dvorecký agroferm, cattle farmyard manure and solo mineral fertilizers, compared to an unfertilized control. All plots, except the control, were fertilized to achieve the same level of nutrients, as determined by the soil analyses and the chosen target yield. We assessed the following traits at harvest: weight of above-ground mass, marketable yield, head weight and head diameter. Levels of ascorbic acid, nitrates, dry matter and mineral ions (potassium, sodium, calcium and magnesium) were measured in the heads. Agormin T significantly increased the weight of above-ground mass and total marketable yield. All organic fertilizers significantly increased head weight and head diameter in comparison to both the unfertilized control and mineral fertilizers. Ascorbic acid levels were not significantly affected by the fertilizers. The highest value of ascorbic acid was observed for farmyard manure, the lowest for Dvorecký agroferm. Dried fertilizers had no positive effect on ascorbic acid levels and total solids, as compared to farmyard manure. In contrast, Agormin T resulted in significantly lower levels of dry matter. Solo mineral fertilization resulted in the highest levels of nitrates in cauliflower heads. Fertilization with Agro and farmyard manure significantly increased the levels of nitrates in heads, as compared to the control, but all values were under the hygienic limit. The different fertilizer treatments did not have any significant effects on the levels of mineral cations. The dried granulated fertilizers Agormin T, Agro and Dvorecký agroferm were shown to be good alternatives to bulky farmyard manure for early ripening cauliflower. Only Agormin T decreased the dry matter content in heads.

Early Maturing

This study compared the carcass characteristics of ram and ewe lambs from South African wool, dual-purpose, meat, and fat-tailed sheep types, reared to produce premium lamb carcasses. The lambs were reared on a feedlot diet (10.41 MJ ME/kg feed and 19.06% crude protein) from weaning (30 kg live weight) until they attained a back-fat depth of ~4 mm, measured using ultrasound. After slaughter, the carcasses were assessed for retail cut yields, composition, and physical meat quality. Later, maturing lambs attained heavier carcass weights than early maturing breeds (~20.7 kg vs. 16.9 kg, respectively; p ≤ 0.05), and differences in carcass composition and retail cut yields were ascribed to differences in the frame size and pattern of fat deposition of the respective breeds. Small differences in physical meat quality were observed, with meat from Dormer and Namaqua lambs having notably higher shear-force values (~46 N) than that from Meatmaster carcasses (~34 N). These differences though are expected to have little influence on the perceived quality of the meat.

Cultural Requirements

Broccoli (Brassica oleracea var. italica), a popular vegetable crop, has one of the most exacting climatic and cultural requirements, which limit its commercial production to a few favored locations. A field experiment was conducted at Mizoram University, Tanhril, Mizoram during winter of 2013/2014 to find out the effect of time of sowing on plant performance and yield of broccoli. Six sowing time was done viz. 17 October (T1), 24 October (T2), 31 October (T3), 7 November (T4), 14 November (T5) and 21 November (T6) with plant spacing of 45cm x 45cm. Yield and yield contributing characters were significantly influenced by the planting time. Highest average weight of marketable curd per plant (199.20 g) was obtained from T2, whereas lowest average weight obtained from T6 (75 g). The influence of planting time also showed significant difference on the calculated yield (tonnes per hectare) of broccoli, in which T2 showed highest marketable yield of 9.83 t/ha.
