Abstract

The yield of many crops can be increased by irrigating them with magnetically treated water (MTW). The aim of our research was to determine if the efficacy of a soil-applied herbicide such as metribuzin against weeds could be affected by MTW. A split-plot randomized complete block experiment was designed with two main plots, including potato ( Solanum tuberosum L.) irrigated with equal volumes of MTW and non-MTW. Sub-plots were weedy control, weed-free control (hand-weeded), and pre-emergence application of metribuzin at 420 and 525 g a.i. · ha–1. Generally, MTW induced the seed germination and vegetative growth of Amaranthus blitoides S.Watson and Convolvulus arvensis L., resulting in a reduction of the total tuber yield of potato from 1.47 to 1.18 kg · m–2. MTW improved the efficacy of weed control strategies, resulting in an improvement of the total tuber yield and the water use efficiency of potato. The total tuber yield when metribuzin was applied at 420 g a.i. · ha–1 with MTW (3.51 kg · m–2) was more than when metribuzin was applied at 525 g a.i. · ha–1 with non-MTW (2.76 kg · m–2). It can be concluded that the use of MTW can be a safer crop production method by reducing the required dosage of metribuzin to control weeds. Considering the fact that the use of MTW without herbicide application increased the density of weed species, this method should be limited to a scenario where weeds can be effectively controlled.

Abstract

The article reviews one of the important problems of water usage – operational management of irrigation. The article discusses a methodological approach to the estimation of economic efficiency of water usage in the conditions of climate change in the territory concerned. So far, there has not been a simple method to determine this indicator. When assessing climatic conditions, taking into account their influence on the productivity of agricultural crops, it is necessary to take into account meteorological factors that have a decisive influence on the development of agricultural crops and, accordingly, determine their yield. These include primarily heat and moisture. Moreover, it is necessary to take into account their possible negative influence on the development of plants, considering that for each crop a certain optimum regime of temperature and soil moisture is required in different phases of its growth. To assess climatic conditions taking into account the potential crop productivity, we can use the CPA formula. Calculations have shown a close relationship between the CPA and the yield of agricultural crops. Correlation coefficients of the obtained bonds vary from 0.85 to 0.98 depending on the culture and the territory.

Abstract

In furrow irrigation, the maximum lateral movement of water in ridges is more desirable than the vertical downward movement. This can be achieved by compacting the furrows. Thus, the study examines the impact on furrow soil compaction by tractor wheel trafficking during mechanical operations in the different soil types. In this experiment, the three-wheel tractor compaction includes: 1) control (no soil compaction), 2) compaction through 3-wheel tractor passes, and 3) compaction through 6-wheel passes under three different soil textural classes such as: clay loam, silty clay loam and silty loam soils. The impact of various treatments on clay loam, silty clay loam, and silty loam under 3- and 6-wheel passes showed increased bulk density (7–12%), field capacity (9–19%), ridge storage efficiency (35–38%), water use efficiency (16–20.5%) and decreased soil porosity (7–16%), infiltration (8–20%), and furrow storage efficiency (28–41%) over the control. This study shows comparable results of 6-passes with other studies in which more than 6-passes were used to compact the soil. This study suggested that farmers can maximise water use efficiency by compacting their furrows using 6-passes tractor trafficking.

Abstract

Improving water productivity (WP) through deficit irrigation is crucial in water-scarce areas. To practice deficit irriga-tion, the optimum level of water deficit that maximizes WP must be investigated. In this study, a field experiment was con-ducted to examine WP of the three treatments at available soil water depletion percentage (����) of 25% (reference), 45% and 65% using a drip irrigation system. Treatments were arranged in a randomized complete block design. The water deficit was allowed throughout the growth stages after transplanting except for the first 15 days of equal amounts of irrigations during the initial growth stage and 20 days enough spring season rainfall during bulb enlargement periods. Physical WP in terms of water use efficiency (WUEf) for treatments T1, T2, and T3 was 9.44 kg∙m–3, 11 kg∙m–3and 10.6 kg∙m–3 for mar-ketable yields. The WUEf and economic water productivity were significantly improved by T2 and T3. The WUEf differ-ence between T2 and T3 was insignificant. However, T2 can be selected as an optimal irrigation level. Hence, deficit irriga-tion scheduling is an important approach for maximizing WP in areas where water is the main constraint for crop produc-tion. The planting dates should be scheduled such that the peak water requirement periods coincide with the rainy system.
