ABSTRACT Kale is a vegetable that has high nutrition content, and balanced fertilization is essential to ensure high yield and quality of agricultural products. Curly kale, less known than regular leaf kale, is a new possibility for consumption. However, little is known about the influence of the type of fertilization on nutritional characteristics. This study aims to evaluate the influence of using organic fertilizers on the productivity, microbiological, and physico-chemical characteristics of Darkibor hybrid curly kale. The treatments consisted of three sources of organic fertilizers, one of organomineral fertilizer, and the control (without fertilization). The highest productivity was observed for kale that was treated with fertilizer in the organomineral composition in all harvests. For microbiological analyses, there was no contamination in all treatments, following legislation. There was no significant difference between treatments for the physicochemical composition, highlighting the high levels of phenolic compounds and proteins in curly kale. There was no difference between treatments regarding the mineral content of the leaves. Organic and organomineral fertilizers made it possible to produce curly kale with adequate physicochemical composition, free from microbiological contamination and heavy metals.

The article presents the results of vegetation-field studies (for 2018-2020) to study the effect of trace elements on the yield and quality of greens and root crops of parsley on heavy loamy chernozems on loess-like loams. A soil mixture was poured into the vessel at the rate of 10 kg of heavy loamy chernozem. Microelements were introduced into the soil in an amount: boron – 1.0 mg; zinc – 2.5 mg; copper – 0.5 mg; manganese – 5.0 mg; molybdenum – 1.0 mg; cobalt – 1.0 mg; iodine – 2.0 mg of active ingredient per kilogram of soil. In the prepared soil, 100 parsley seeds were sown in vessels at the beginning of May. Trace elements were aplicated in the form of an aqueous solution of salts 20 days before chemical analyzes. Molybdenum in the form of ammonium molybdenum (0.05 % solution), manganese – in the form of manganese sulfate (0.6 %, solution) and boron – in the form of boric acid (0.15 % solution). The experiments were carried out in triplicate. Collecting greens was carried out when the plants reached a height of 20–25 cm, leaving petioles 2 cm high from the head of the root crop. The results of the research found that microelements: boron, copper, manganese, molybdenum and cobalt on chernozem on average over two years contributed to an increase in seed germination by 1.2–1.3 %, and the introduction of iodine into the soil slightly reduced seed germination. Parsley shoots appeared together, which was also influenced by the water–air properties of the soil. At the same time, the plants were well leafy and had a darker green color of the leaves, increased the productivity of greens and parsley root crops. In the variant where organic fertilizers were applied to the soil under the predecessor, the microelements increased the yield. This is due to the fact that organic fertilizers were introduced under the previous crop, when decomposed in the soil, they provide the plants with microelements. The increased yield of parsley root crops was obtained from the introduction of molybdenum and a double dose of copper. An increased yield of root crops compared to the control (without feeding) was obtained, respectively: cobalt – 151 g, double dose of copper – 135 g, copper – 108 g and zinc – 106 g. Thus, the use of trace elements for parsley in order to obtain high yield and quality marketable products are best used on poor soils of these elements.

Organic fertilizers were evaluated on jalapeno pepper (Capsicum annuum L.) and on their effect on the soil content of nitrogen (N), phosphorus (P), electrical conductivity (EC), pH and organic matter (OM), at the Experimental Station of the Agriculture and Zootechnics Faculty (FAZ-UJED), Ejido Venecia, Durango, México. The assayed experimental fertilizers were vermicompost (VC) with 0 and 3 Mg ha−1, in factorial combination with solarized manure (SM), with 0, 40, 80, and 120 Mg ha−1, and an inorganic fertilization nitrogen-phosphorus-potassium (NPK) at 150–100–00 Mg ha−1. Microbiological analyses were performed to evaluate the presence of Salmonella spp. The highest yield was 56.2 Mg ha−1 with 120 Mg ha−1 SM, which was statistically similar to 40 and 80 Mg ha−1; the highest P content (70.7 mg kg−1) and OM (3.7%) occurred with 120 Mg ha−1 SM. The inorganic fertilizer reflected the lowest OM (1.1%). Nutrients provided by SM were sufficient to satisfy the crop needs. Values of pH, EC and N were not affected by SM. The fruit quality was not affected by the organic fertilizers. Most fruits were classified as Second-Class Quality (60%), followed by First-Class Quality (25%). Microbiological analyses were negative for Salmonella spp., suggesting that the SM is effective in its elimination.

Gaining high yield of potato is very crucial for farmer and quality also has a great impact on their production. Beside the quality and yield using the amount of irrigation also important to reduce water lose. The tuber yield and quality of potato (Solanum tuberosum L.) is impacted by irrigated water. This study was carried out in two respectively season (2017 and 2018) in Halabja province of Kurdistan regional of Iraq to evaluate the impact of irrigation interval on quality and tuber yield in potato cultivars. In this study there are  four irrigation intervals (3,5,7 and 9 days) used by furrow irrigation method which subjected in complete randomized design (CRD) with three replications. The potato tuber production in 3 day interval showed highest percentage also protein and starch content was recorded highest in both year of cultivation, but the abscisic acid was affected by more irrigation which in 3 day interval irrigation the rate was less than other. Also in 5 day interval irrigation the rate was acceptable because there is no significant difference in terms of tuber yield, protein and starch content if compare with 3 day interval irrigation in particular for those area faced restricted in using water irrigation.

Caraway has very low competitive ability against most of weed species. Therefore, it is important to choose a suitable herbicide control, especially at biennial caraway. The experiments with the herbicides applied in caraway were found in pure growth, with variety Kepron (with standard length of ve­ge­ta­ti­ve period). The aim of the trials was to find out the differences at achenes yiled and essential oil content after the treatment by the various herbicides, applied preemergently. Also, the selective ac­ti­vi­ty of individual herbicides was tested, including the different doses. The herbicides used in the ex­pe­ri­ments had enough level of selektivity on the plants of caraway. They had a positive effect on the yiled comparing to non-treated control variant in all observed years. There was no statistically significant difference in essential oil kontent between the treated variants and non-treated control. On the basis of these results, the most suitable herbicide was chosen for the „minor“ registration for caraway.

This investigation was carried out during the two summer seasons of 2015 and2016 in sandy soil on potato culitvar "Sante" to study the effect of using 100%compost (15 t/fed.) and 50% compost + nitrogen fixing bacteria (Azotobacter, andPseudomonas alone or together) on potato yield and quality as compared to theconventional mineral fertilization (120-75-150 kg/fed. NPK + 5 toncompost/fed.(control)). No significant differences in tubers yield/fed. were detectedbetween mineral fertilization (control) and using 100% compost (15t/fed).However, control treatment significantly produced a high yield per feddan,more than using 50% compost + any biofertilizer treatment.Using composttreatment at 15 t/fed.execeed all biofertilizer treatments in marketable yield in bothseasons, but without significant differences as compared with mineral fertilization(control).No significant differences in tuber dray matter and content of starch intuber were found between using compost treatment at 15 ton/fed. and mineralfertilization treatment (control)in both seasons. Nevertheless, application of 50%compost+ 4 applications of Azotobacter and Pseudomonas had the highest tuberconcentrations of starch and nitrogen with significant differences as compared withthe mineral fertilization.Using50% compost + 4 applications of Azotobacter orPseudomonas or both (Azotobacter + Pseudomonas )and application of 100%compost caused producing potato tubers with the lowest concentration of nitratewith significant differences as compared with the mineral fertilization. Nosignificant differences were detected between mineral and organic fertilizersconcerning P and K concentrations in tubers.

The development of rational system of basic soil tillage results in formation of sufficiently high crop yields. A two-factor field experiment was carried out to address these issues when cultivating winter rape cultivars on light chestnut soils of the Primorsko-Caspian sub-province of the Republic of Dagestan. VEM (standard), Elvis and Meteor winter rape cultivars were studied in the experiment. The following methods of soil tillage were studied: real tillage (control), subsoil tillage. The research revealed that there was no significant difference in agrophysical indicators between the soil cultivation variants. Data on weed infestation of winter rape fields showed that the number of weeds and their weight increased significantly after subsoil tillage. At the budding stage, the number of weeds increased 2.1-fold compared to the control (real tillage), and the weight of weeds increased 1.88-fold. During flowering stage, these indicators were 2.2 times higher. The maximum yield in all variants of the experiment was formed by Elvis cultivar - 44.9 and 41.4 t/ha, respectively, which is more than VEM (standard) and Meteor cultivars by 20.4 t/ha (7.9 %) and 20.0 t/ha (8.7 %), respectively. The yield of Meteor cultivar in these variants was also high and amounted to 41.6 and 38.1 t/ha, respectively, which was higher by 11.5 and 10.4 % compared with the standard. The greatest increase in the fresh yield was provided by real tillage. On average, the yield increased by 8.7 % for varieties in comparison with subsoil cultivation. Elvis cultivar formed the best quality indicators, followed by Meteor cultivar.

Boron is an important micronutrient, required for all plant growth, and critical for high yield and quality of crops. The aim of the present research was to determine the effects of boron on pot-grown parsley (Petroselinum sativum Hoffm.). The experimental design consisted of four treatments using Hoagland-Arnon (1950) nutrient solutions with two different boron concentrations (B1 - 15 ppm and B2 - 150 ppm), each with and without 10 ml humic acid addition (HB1 and HB2), and controls with full strength Hoagland-Arnon solutions. Growth analyses of the parsley revealed that 15 ppm boron application caused an increase in root length leaf fresh and dry weight root fresh and dry weight and leaf area compared to control values. 150 ppm B (B2) concentration decreased all growth parameters compared to controls. The two humic acid treatments (HB1 and HB2) did not increase any of those growth parameters either in controls (C) or in the two boron (B1 and B2) concentrations. Analysis by (ICP-MS) revealed that B content in the leaves increased gradually in B1 and B2, as well as in both humic treatments where in HB2 it increased to 99.38% compared to B1. In the leaves, Mn, Zn and Fe contents behaved the same as B, increasing in all treatments, with the amounts in HB2 being significantly greater than in C, B1 and B2 leaves.
