Abstract. A study on some operational characteristics of a direct sowing machine-tractor unit has been carried out in wheat sowing. It is performed by Horsch Avatar 6.16 SD direct seeder aggregated to John Deere 7250 R tractor. It was found that 91% of the area is sown at sowing rate of 195 kg seed/ha. The remaining 9% are sown either at lower or higher rate. Engine rotations of the seed unit have been established at work mode, i.e. when the seeder is sowing, these are 1594.81 min-1, in idle state the rotations are 912.08 min-1, and in transportation mode are 1860.36 min-1. The relative share of engine use has also been determined: when the seeder is sowing, it is 56.68%, when the seeder unit is in idle mode, it is 14.54% and when the unit is in transportation mode – 28.78%, respectively. The actual operation speed of the seeder unit when sowing wheat was 10.40 km/h and the real hourly productivity – 3.7 ha/h.

Abstract The experiment is carried out in the conditions of semi-desert flat agricultural landscapes of light chestnut soils. The object of research is a 4-field crop rotation (factor A), variants of the main tillage (factor B) and crops superimposed on the tillage options with the Don-114 seeder (a seeder for direct sowing). The placement of options (A) is sequential and options (B) are arranged in blocks in three tiers. The main soil tillage was carried out by the following tools: mouldboard tillage to the depth of 25-27 cm by plough PN-4-35; non-mouldboard tillage to the depth of 25-27 cm by the tool OCHO-5-40 with the rack “Rancho”; surface one to the depth of 8-10 cm by the tool BDM-4.2, and 4-field grain-fallow crop It was found that a higher content of nutrients is in fallow preferably at non-mouldboard soil treatment, in some years, which has an optimal moisture supply, and control (mouldboard) one in comparison with lower levels of surface soil treatment in all years of the research. The main comparison in the change in nutrients in fallow fields is observed precisely for different methods of soil cultivation.

Agricultural Research And Development

The Transylvanian Plain has a particular aspect, as the hilly areas are predominant and here the soil erosion phenomena through levigation are frequently encountered. The effect of water availability on yields has been thoroughly researched, being one of the main limitative factors of the winter wheat yields. Starting from these considerations, during the agricultural years 2012-2018, a bi-factorial yield test was performed at Agricultural Research and Development Station (ARDS) Turda, for a period of seven years. The study explored the influence of the water status under the influence of two tillage systems and the climatic conditions specific for this area on winter wheat yields. In the field conditions of Turda during experimental interval, the soil tillage system had a rather small impact on the winter wheat yields. In the conventional system (CS) a reserve of accessible water is preserved better during the spring period, this being attributed to a better infiltration into the soil of winter precipitation (snow). In the conservative system (NT), the observed trend suggests that restoration of the ground water reserve is more difficult than in the CS but the loss of water in the CS is just as fast.

Wheat is one of the world's most abundant and essential food crops. It covers a significant area of the earth's surface, higher than any other plant, and tends to be among the top strategic crops. Wheat contamination with fungi leads to rapid deterioration of quantity and quality of wheat products. Many of those fungi are potential mycotoxins producers. This study aimed to isolate and identify fungi that contaminating the wheat grains from the Misurata Agricultural Research Center area and the South Region of Libya. Fungi contaminating wheat grains were isolated on Potato Dextrose Agar (PDA) and identified by culture characteristics and microscopically. Fungal filtrates of two fungal isolates, Aspergillus niger and Rhizopus sp., were tested for their effects on the germination and seedlings of wheat grains. Furthermore, the effect of acetonic extracts of Black pepper (Piper nigrum) on the growth of the isolated fungi was also investigated. Ten types of fungi belonging to four genera were isolated and identified. The germination rate of wheat grains irrigated with the filtrate of A. niger and Rhizopus sp. was 20% and 80% respectively, compared with 100% of the control grains, which were irrigated with water. The culture filtrates of both A. niger and Rhizopus sp. affect not the only percentage of grains germination but also the morphology of wheat seedlings. It adversely affected the length of the radicles and coleoptiles. The acetone extract of P. nigrum showed inhibitory effect (85.7% ± 3.7 and 44.0% ± 3.1) on the germination of A. niger and Rhizopus sp. respectively. This study concludes that fungal secretions have pathogenic effects on plant growth, which can lead to potential health risks for the human population. Biological control such as Piper nigrum extracts can be an alternative to chemical pesticides for controlling fungal pathogens and their secretions.

A pot experiment was carried out at the Laboratory of Department of Agronomy, Hajee Mohamad Danesh Science and Technology University (HSTU), Bangladesh during 2016 to evaluate the response of maize varieties at germination and seedling growth stages under salt stress. The seeds of the BARI (Bangladesh Agricultural Research Institute) developed four maize varietiesviz.Barnali, Khoi Vutta, Mohor and BARI Maize 5 were placed in plastic pots (each of 25 cm length and 12 cm width) on sand bed irrigated with tap water (control), 100 and 200 mM NaCl salt solutions. It was replicated in thrice with completely randomized design (CRD). Salinity stress significantly affected the germination characters and seedling growth parameters of maize varieties. The germination percentages (GP) and germination rate (GR) reduced significantly with increasing salinity, and the variety Khoi Vutta showed the highest GP and GR followed by Barnali and Mohor showed the lowest GP and GR followed by BARI maize 5. Under high salinity level, seedling growths characteristics like shoot and root lengths, fresh and dry weight of shoot and roots reduced remarkably in the variety Mohor indicating salt susceptible while the minimum reduction of the aforementioned traits was observed in the variety Khoi Vutta demonstrating high salt tolerant variety. The studied varieties can be ranked on the basis of salt tolerance as Khoi Vutta > Barnali > BARI Maize 5 > Mohor from the experiment.
