AbstractQuinoa (Chenopodium quinoa Willd.) is capable of adapting to multiple environments and tolerating abiotic stresses including saline, drought and frost stress conditions. However, the introduction of quinoa into new environments has disclosed adaptation challenges. The principle factor affecting crop pollination is heat stress at flowering, which leads to sterile plants. To investigate the effect of high temperatures during the sensitive phenological phases, flowering and seed germination, a Danish-bred cultivar (cv. Titicaca) was grown in climatic chambers. Selection of the cv. Titicaca was based on the fact that it is the most extensively used cultivar in the Sahel and Middle East and North African region. The results of this research demonstrated that temperatures exceeding 38 °C hindered seed germination and pollination, and therefore, seed yield at harvest. At 38 °C, seed yield losses were 30%, whilst seed germination percentage declined below 50%. In addition, the results of the present research were compared with field observations from Burkina Faso in order to determine the spatiotemporal suitability of this crop with respect to temperature stress. Although many other abiotic stresses need to be considered when defining crop calendars (e.g. heavy precipitation in July and August), this research proposes the following growing periods to avoid heat-stress conditions at flowering: Sahel (July–September and November–February), Soudano–Sahel (June–February) and Soudanian zone (all year round).

Sword bean (Canavalia gladiata (Jacq.) DC.), also named Jack bean or beach bean, originates from India and China. The crop has been completely unknown in Poland and other Central European countries. Two Chinese cultivars: early and late, were produced in Western Poland. During the vegetation period, additional watering, staking and strong chemical control against aphids and bean weevils were applied. In the field, plant emergence rates, blooming period, number of seeds per pod and total seed yield were evaluated. In the laboratory 1000 seed weight, seed germination, vigour and water absorbing capacity were evaluated. Additionally, variability of seed size was recorded. The measurement showed that the most stable for seed was width and the least - length. Both cultivars had good emergence rates in the field - over 60%. Only the early cultivar produced germinating seeds when grown in Poland, whereas the late one produced soft and immature seeds of the size of the wheat grain. The onset of blooming for the early and late cultivars were at the end of June and middle of August, respectively. On average, one pod had 7.3 seeds. The early cultivar gave good seed yield - 2067 kg ha-1. The germination rate of the produced seeds was over 90%. The mean germination time was shorter at 25 °C than at 15 °C. Water absorption capacity curves, although different for the 1 hour time point, were basically the same for both Chinese and Polish seeds. The total proteins content for both cultivars was almost 25%. In the climatic conditions of Western Poland, it was possible to produce high amounts of well-germinating seeds of the early sword bean cultivar in the field.

This study was conducted for two seasons from 2018 to 2020 to determine fenugreek genotypes yield and quality characteristics under semiarid climatic conditions. Fenugreek genotypes viz., Adana, Afghanistan, Gaziantep, Iraq, Kahramanmaraş, Kayseri, Mardin, Şanlıurfa with varieties of Berkem and Gürarslan were used as plant material in the research. Field trials were conducted with four replications according to the randomized complete block design. The results revealed that the time to emergence varied from 16.0 to 19.9 days, 50% flowering from 160.9 to 170.4 days, and the vegetation period from 202.0 to 209.3 days. According to the results of two years of research, plant height varied from 64.60 to 78.70 cm, first pod height from 25.26 to 41.76 cm, pod width from 2.91 to 3.29 mm, pod length from 10.07 to 12.60 cm, number of pods per plant from 12.00 to 18.73, number of seeds per pod from 12.55 to 15.55, biological yield from 5.12 to 7.62 t/ha−1, seed yield from 0.91 to 1.38 t/ha−1, harvest index from 17.91 to 24.35%, thousand-seed weight from 13.87 to 17.45 g, fatty oil content from 5.18 to 9.16%, fatty oil yield from 49.3 to 111.6 kg ha−1, and the trigonelline ratio varied from 0.71 to 1.32%. Statistically significant differences (p ≤ 0.05) were observed for the pod width, while highly significant differences (p ≤ 0.01) were observed for all other parameters. According to the research results, Mardin, Kayseri, and Adana genotypes were statistically in the same group with Berkem cultivar in terms of seed yield. A higher fatty oil content was obtained in the Afghanistan genotype (9.16%) than in the Berkem cultivar (8.11%). Gaziantep, Mardin, Şanlıurfa, and Kayseri genotypes contained higher trigonellin than the Berkem and Gürarslan varieties. The obtained information was the result of the Mardin, Kayseri, Adana, Gaziantep, and Afghanistan genotypes that can be used in breeding studies.

Quinoa (Chenopodium quinoa Willd.), an Andean crop, is native food plant of highnutritional value and its cultivation is increasing rapidly in the World. Backgroundstudies should be conducted on the determination of appropriate quinoa varietiesfor different ecologies for its cultivation to become widespread in a healthy way.This study was conducted in 2015 and 2016 in Erzurum and Igdir non-irrigationconditions in the Eastern Anatolia of Turkey. The locations have differentecological characteristics from each other. The field experiments were conductedwith 9 varieties in each location in a randomized complete blocks experimentaldesign with four replications. The grain yield and some related characteristics wereexamined in the study. The grain yield and related characteristics of quinoa variedsignificantly depending on varieties and locations in the study. According to thetwo-year results, quinoa cultivation is a risky in Erzurum which has a high altitudeand short vegetation period. The grain yields ranged between 110-599 kg ha-1 andwas found to be quite low. In the Igdır location, 933-1646 kg ha-1 of seed yield wasobtained from the varieties. The earliest cultivar is Q-52, it has matured in Erzurumat 102 days, Igdir at 118 days. The latest maturation (138 days) was determined inthe Oro de Valle cultivar in Igdir conditions. According to these results, moquArrochilla, Q-52, Oro de Valle, French Vanilla and Rainbow cultivars can berecommended for non-irrigated conditions of these locations provided that it isseeded early in the spring. However, Erzurum and similar locations are not suitablefor the agriculture of this plant due to short plant growing period.

This study provides the analysis of drought conditions of vegetation period in 1982-2014 year in two Lithuanian regions: Kaunas and Telšiai. To identify drought conditions the Standardized Precipitation Index (SPI) was applied. SPI was calculated using the long-term precipitation record of 1982–2014 with in-situ meteorological data. Calculation step of SPI was taken 1 month considering only vegetation period (May, June, July, August, September). The purpose of investigation was to evaluate the humidity/aridity of vegetation period and find out the probability of droughts occurrence under Lithuanian climatic conditions. It was found out that according SPI results droughts occurred in 14.5 % of all months in Kaunas region and in 15.8 % in Telšiai region. Wet periods in Kaunas region occurred in 15.8 %, and in Telšiai region occurrence of wet periods was – 18.8 % from all evaluated months. According SPI evaluation near normal were 69.7 % of total months during period of investigation in Kaunas and respectively – 65.5 % in Telšiai. The probability for extremely dry period under Lithuania climatic conditions are pretty low – 3.0 % in middle Lithuania and 2.4 % in western part of Lithuania.

Indian mustard (Brassica juncea L. Czern) cultivation is suggested for regions with short seasons and low rainfall. Although there have been many studies conducted on agronomic production of mustard in Iran, the information regarding the interactive impact of cropping seasons and nitrogen fertiliser on growth characteristics and yield quality of mustard plant is still insufficient and requires further investigation. This study focused on the possible implications of different cropping seasons and different nitrogen levels on selected agronomic traits in mustard. In this experiment, five different doses of nitrogen and two sowing periods were used to assess for their combined effects on the growth parameters, seed yield and agronomic characteristics of mustard in the semi-arid climatic conditions of Takestan. The results revealed that cultivation seasons and nitrogen rates had a significant effect on plant height, biomass yield, number of siliques per plant, seed oil content and seed yield.

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.

Examination is a way to select talents, and a perfect invigilation strategy can improve the fairness of the examination. To realize the automatic detection of abnormal behavior in the examination room, the method based on the improved YOLOv3 (The third version of the You Only Look Once algorithm) algorithm is proposed. The YOLOv3 algorithm is improved by using the K-Means algorithm, GIoUloss, focal loss, and Darknet32. In addition, the frame-alternate dual-thread method is used to optimize the detection process. The research results show that the improved YOLOv3 algorithm can improve both the detection accuracy and detection speed. The frame-alternate dual-thread method can greatly increase the detection speed. The mean Average Precision (mAP) of the improved YOLOv3 algorithm on the test set reached 88.53%, and the detection speed reached 42 Frames Per Second (FPS) in the frame-alternate dual-thread detection method. The research results provide a certain reference for automated invigilation.
