The aim of study was to assess the effect of bottom sediments on the concentration of macronutrients (K, P, Na, Mg, Ca) and trace elements (Zn, Cd, Pb, Cr, Ni, Cu) in the plant test. The experimental design comprised 6 treatments: soil (control), soil + 5% of sediment, soil +10% of sediment, soil + 30% of sediment, soil + 50% of sediment and sediment (100%) in relation to the soil dry mass. The test plant - maize was harvested after 70 days of vegetation. Bottom sediment added to soil had a positive effect on maize biomass in the lowest dose, i.e. 5%. Higher doses of the sediment caused a reduction in maize yield. Bottom sediment positively affected concentration of nutrients: N, Mg, Na, K, Ca, Zn, Ni, Cu of maize shoots. However, the shoot biomass did not meet for fodder with respect to quality. Applied bottom sediment, has high content of sandy fractions, acid reaction and low concentration of organic carbon, nitrogen, phosphorus and potassium, can not be used as a fertilizer. Using bottom sediment from Narożniki reservoir in plant cultivation, one should take into consideration a necessity of application of supplementary NPK fertilization due to low concentration of these ...
The aim of the study was to evaluate the effect of four fertigation levels (25, 50, 75 and 100% of fertilizer dose, 240:100:200 kg N:P:K ha-1) and to compare with conventional practices (CP). The fertigation levels F1 25% of total fertilizer (60:25:50 kg N:P:K ha-1) treatments, F2 treatment is 50% of total fertilizer (120:50:100 kg N:P:K ha-1), F3 treatment is 75% of total fertilizer (180:75:150 kg N:P:K ha-1), F4 treatment is 100% of total fertilizer (240:100:200 kg N:P:K ha-1). The experiment was conducted during 2012 summer (from 20 June to 15 September) under the field conditions in the Menzilat soil series (Typic Xerofluvents) which is located in the East Mediterranean coastal part of Turkey. The experiment was designed as a completely randomized-block with three replications. The maize plant (Zea mays L.) was sown as second crop following with wheat cultivation. The maize yield was higher in F3 fertigation level treatment (12.47 Mg ha-1) compared to the other treatments. Lowest yield was recorded in F2 (8.45 Mg ha-1) treatment. The results shown that the half of the fertilizer application with conventional practices and the other half with fertigation are more efficient under Menzilat soil series conditions. For future, it is important ...
Drought is an important factor that causes a decrease in yield and quality in regions where second crop silage plants are grown. One of the biggest problems in animal husbandry is feed. Especially silage feed production tends to decrease in areas with increasing water deficit and where water needs cannot be met. The high water requirement of the corn plant requires irrigation in arid and semi-arid regions. However, in order to continue the production of silage fodder in regions where water resources are insufficient with the increase of drought, it will be necessary to grow forage plants that can be an alternative to corn plant. In previous studies, it has been discussed whether the sorghum plant is an alternative to the corn plant. The aim of this study is to determine the drought sensitivity index based on the yield values of both plants in wet and dry conditions. Thus, it will be determined whether the sorghum plant will be an alternative to the corn plant in terms of drought. The identification and selection of drought-resistant cultivars and species is possible using various indices. In this study, second crop silage maize and sorghum crops were grown in Kahramanmaraş conditions for two ...
Efficient water management is critical in modern agriculture, particularly in the face of increasing water scarcity and climate variability. Maize, a major cereal crop worldwide, is highly sensitive to water availability, making irrigation management a key factor in sustaining both yield and grain quality. This study was conducted to investigate the impact of deficit irrigation, including partial root-zone drying (PRD) techniques, on the grain quality parameters of maize. The experiment evaluated the effects of different irrigation levels 100% (full irrigation), 75%, 50% (with and without PRD), and 25% on key biochemical attributes of maize grain. Results revealed a significant influence of irrigation level on most grain quality parameters. ADF content increased progressively with reduced water application, peaking at 3.90% under 25% irrigation, while the lowest value (3.43%) was recorded under full irrigation. Conversely, NDF and hemicellulose contents were highest under full irrigation (19.13% and 15.70%, respectively) and decreased under severe water stress. Starch content also declined with increasing water deficit, with the maximum value under full irrigation and the lowest (63.33%) under 25% irrigation. Protein content was highest in the fully irrigated treatment, though differences among treatments were not statistically significant. Oil content showed a similar trend, with maximum values ...
