An experiment aimed at examining the effect of bulb size and the method of application of Asahi SL biostimulator on the growth and yield of <em>Allium moly </em>L. was conducted in the years 2005–2008. Four sizes of bulbs were used in the experiment (3–4, 4–5, 5–6, and 6–7 cm in circumference). Asahi SL was applied in the following combinations: bulb soaking for 45 minutes in the biostimulator solution prior to planting; plant spraying at the green bud stage; soaking combined with plant spraying; and the control treatment without application of the stimulator. Asahi SL was applied at a concentration of 0.2%. After the first frost, the experimental plots were mulched with wheat straw. During the experiment, the decorative value of the plants was evaluated and the following features were determined: inflorescence stem length, inflorescence diameter, and number of flowers per inflorescence. Total yield was evaluated after bulb harvest. The size of <em>Allium moly </em>bulbs planted was found to determine the quality of inflorescence stems and total yield of daughter bulbs expressed in their number and weight. Inflorescence stems of high ornamental value and high total yield of daughter bulbs resulted from planting bulbs of 5–6 and 6–7 cm in circumference. The application of 0.2% solution of Asahi by spraying green buds or the combination of spraying and bulb soaking prior to planting are very beneficial for the quality of inflorescence stems and yield of daughter bulbs. The application of 0.2% solution of Asahi SL by plant spraying leads to an increase in total quantitative yield of bulbs by 10% or 8% in case of the combined use of both application methods. Bulb soaking combined with plant spraying leads to an.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Studies were conducted for 2 years in root-knot-nematode-infested soils to determine growth and yield response of `Dasher II' cucumbers (Cucumis sativus L.) to double-cropping with nematode-resistant tomatoes (Lycopersicon esculentum Mill.), using nematode-free cucumber transplants and preplant treatment with ethoprop nematicide. Cucumbers grown following the nematode-resistant `Celebrity' tomato during the same season produced significantly more plant dry weight, more fruit per plant, and higher premium and total yields than did cucumbers double-cropped with the nematode-susceptible `Heatwave' tomato in both years. The cucumber produced longer stems in 1992 and fewer culls in 1993 following resistant tomatoes. Cucumber plants raised in nematode-free soilless mix for 3 weeks before transplanting produced significantly longer stems and more plant dry weight than did direct-seeded cucumbers in 1992, but not in 1993; however, they produced significantly higher premium yield in both years, and higher total yield, more fruit per plant, and fewer culls in 1993. Preplant treatment with ethoprop significantly increased cucumber stem length, dry weight, premium and total yield, and number of fruit per plant in 1992 but not in 1993. Ethoprop treatment had no effect on the percentage of culls in either year. Chemical name used: O-ethyl S,S-dipropyl phosphorodithioate (ethoprop).

Field experiment on production systems of `Selva' day-neutral and `Totem' June-bearing strawberry was established in 1995 on the spring-killed cover crop mulched plots using randomized complete-block design. Seven soil cover treatments consisted of `Wheeler' rye (Secale cereale) and `Micah' and `Steptoe' barley (Hordium vulgare), `Micah' residue applied on soil surface, a wedge of perlite (artificial medium) placed next to strawberry row, perlite with `Wheeler' rye, and no treatment were used. During the early summer, cover crops were replanted between strawberry rows and mowed down after 6 weeks. In both cultivars, plant growth doubled during mid-summer, and `Micah'on surface produced better growth than the growth in other treatments. No significant difference was found on CO2 assimilation rate (mmol·m–2·s–1), leaflet length, and number of leaves and runners among treatments (P ≥ 0.1). Yield of `Totem' was ignored during the establishment year. In `Selva', `Micah' residue on surface produced 36% more crowns per plant and the greatest total yield than that of any other treatment. `Micah' on surface produced 50% more shoot biomass and 45% greater yield compared to `Micah' barley planted in the plot. Total `Selva' yield was 61% greater in perlite treatment than the yield in perlite with `Wheeler' rye and 31% greater than the control treatment. Comparison of `Selva' strawberry total yield and average fruit production between cover crops vs. control treatment using non-orthogonal contrast indicated no significant difference might suggests no detrimental interaction between cover crops and strawberry.

Abstract In order to study the effect of adding humic acid, vermicompost and nano-phosphorous on the growth characteristics and yield of maize. An experiment was carried out in one of the fields located in Afak sub-district - Diwaniyah Governorate - Iraq in the autumn season 2020. The experiment was carried out according to a Complete Randomized Blocks Design with three replications. The treatments included adding humic acid at three levels (0, 10 and 20) kg H−1 and coded (H0, H1 and H2) sequentially, while vermicompost was added at two levels (0 and 4) tons H−1 and coded (V0 and V1) sequentially. While nano-phosphorous was added at three levels (0, 5 and 10) kg H−1 that coded by (nP0, nP1 and nP2) sequentially. The results of the experiment showed outperform the fertilizer combination (VnP1), which consisted of vermicompost (4) H− 1ton and nano-phosphorous (5) kgH−1, as it recorded the highest content of chlorophyll in leaves, the highest plant height, the highest weight of the vegetative and root system, the percentage of protein and the total grain yield (66.53). SPAD and 269.93 cm, 53.53 g and 11.853 g) compared to the control treatment that recorded the lowest values, followed by treatment (V) with a single effect of vermicompost (4) tonH−1, which outperformed in the content of leaves from chlorophyll, plant height, dry weight of the vegetative and root system and the percentage of the protein and total yield which recorded (SPAD 65.77, 263.50 cm, 53.04 g, 11.520 g, 12.25% and 12,393 mcg H−1) compared to the control treatment that recorded the lowest values, as the second level of single nano-phosphorous fertilizer (nP2) was significantly superior compared to the levels addition of nP and comparison treatment.

В статье приведены результаты исследований по изучению влияния минеральных удобрений и куриного помета на продуктивность клубней картофеля отечественной и зарубежной селекции. В исследованиях, проведенных в 2017-2019 гг. на черноземе выщелоченном в условиях Пензенской области, установлено, что при внесении куриного помета и минеральных удобрений повышается урожайность и качество клубней, что непосредственно связано с обеспеченностью растений питательными веществами. Применение куриного помета в дозе 2 т/га позволило повысить общую урожайность клубней исследуемых сортов картофеля на 22,6-29,5, товарных клубней на 24,3-35,5 по сравнению с вариантом без удобрений. Наибольшую урожайность наблюдали на вариантах с совместным применением мочевины в дозе N30 и сульфата калия в дозе К60 и на вариантах с совместным применением аммофоски в дозе N30Р30К30 и сульфата калия в дозе К30. Применение умеренных доз минеральных удобрений и куриного помета в дозе 2 т/га увеличивает не только урожайность клубней картофеля, но и содержание в клубнях сухого вещества, крахмала и нитратов, не превышающих значения ПДК. Совместное применение азотно-калийных и азотно-фосфорно-калийных удобрений с добавлением сульфата калия в дозах К60 и К30 позволяют улучшить качественные показатели клубней по всем изучаемым сортам.The article presents the results of studies on the influence of mineral fertilizers and chicken manure on the productivity of potato tubers of domestic and foreign selection. In the studies conducted in 2017-2019 on leached chernozem under the conditions of the Penza region, it was found that when chicken manure and mineral fertilizers are applied, the yield and quality of tubers increases, which is directly related to the supply of plants with nutrients. The use of chicken manure at a dose of 2 t/ha allowed to increase the total yield of tubers of the studied varieties of potatoes by 22.6-29.5, marketable tubers by 24.3-35.5 compared with the variant without fertilizers. The highest yields were observed in variants with the combined use of carbamide in a dose of N30 and potassium sulfate at a dose K60 and in variants with a combined use of ammophos at a dose N30P30K30 and potassium sulfate at a dose K30.The use of moderate doses of mineral fertilizers and chicken manure at a dose of 2 t/ha increases not only the productivity of potato tubers, but also the content of dry matter, starch and nitrates in the tubers, not exceeding the MAC value. The combined use of nitrogen-potassium and nitrogen-phosphorus-potassium fertilizers with the addition of potassium sulfate at doses of K60 and K30 can improve the quality indicators of tubers for all studied varieties.

The aim of this report was to study the effect of salinity (control: 2dS/m, S1: 4 dS/m and S2: 6 dS/m) and harvest time (first harvest on 9 May 2018 and second harvest on 19 April 2018) on the growth and the chemical composition of Centaurea raphanina subsp. mixta plants. The plants of the first harvest were used for the plant growth measurements (fresh weight and moisture content of leaves, rosette diameter, number and thickness of leaves), whereas those of the second harvest were not used for these measurements due to the flowering initiation, which made the leaves unmarketable due to their hard texture. The results of our study showed that C. raphanina subsp. mixta plants can be cultivated under mild salinity (S1 treatment) conditions without severe effects on plant growth and yield, since a more severe loss (27.5%) was observed for the S2 treatment. In addition, harvest time proved to be a cost-effective cultivation practice that allows to regulate the quality of the final product, either in edible form (first harvest) or for nutraceutical and pharmaceutical purposes as well as antimicrobial agents in food products. Therefore, the combination of these two agronomic factors showed interesting results in terms of the quality of the final product. In particular, high salinity (S2 treatment) improved the nutritional value by increasing the fat, proteins and carbohydrates contents in the first harvest, as well as the tocopherols and sugars contents (S1 and S2 treatments, respectively) in the second harvest. In addition, salinity and harvest time affected the oxalic acid content which was the lowest for the S2 treatment at the second harvest. Similarly, the richest fatty acid (α-linolenic acid) increased with increasing salinity at the first harvest. Salinity and harvest time also affected the antimicrobial properties, especially against Staphylococcus aureus, Bacillus cereus and Trichoderma viride, where the extracts from the S1 and S2 treatments showed high effectiveness. In contrast, the highest amounts of flavanones (pinocembrin derivatives) were detected in the control treatment (second harvest), which was also reflected to the highest antioxidant activity (TBARS) for the same treatment. In conclusion, C. raphanina subsp. mixta plants seem to be tolerant to medium salinity stress (S1 treatment) since plant growth was not severely impaired, while salinity and harvesting time affected the nutritional value (fat, proteins, and carbohydrates) and the chemical composition (tocopherols, sugars, oxalic acid, fatty acids), as well as the bioactive properties (cytotoxicity and antimicrobial properties) of the final product.

Sprout is a nutritious ready-to-eat vegetable. In this study, we examined the effects of ultrasonication treatments (treated with 28, 40 or 80 kHz frequency for 10 min at 25 °C) on the changes in microstructure, seed hydration and germination, sprout growth, sprout quality, and microbial load of two adzuki bean (Vigna angularis) varieties (Kaohsiung 8 and Kaohsiung 10). The results indicated that the ultrasonication at 40 kHz or 80 kHz improved seed hydration and enhanced germination; this is linked to the ultrasound-induced microstructure changes in the hilum and seed coat surface of treated seeds. The ultrasonication-increased sprout growth and yield were possibly attributable to the increased α-amylase activity during germination. Ultrasonication also improved total polyphenols, total flavonoids, and total saponins contents and further enhanced the anti-oxidative activities (FRAP and DPPH) of produce sprouts. The results further indicated that the 40 kHz or 80 kHz treatment decreased microbial loads of treated sprouts to an acceptable level; therefore, these two treatments can be used for germination improvement and an effective microbial control treatment for adzuki bean sprout production.

A pot experiment was conducted to study the effect of goat manure and sugarcane molasses on the growth and yield of beetroot (Beta vulgaris L.) in sandy regosol. The experiment was laid out in a completely randomized design (CRD) with six treatments. The treatments included inorganic fertilizer (T1), 10 t/ha of goat manure alone (T2) and also 10 t/ha of goat manure and 50% triple superphosphate (TSP) with 1-4 t/ha of sugarcane molasses (T3-T6). The results showed that plant growth parameters (leaf length, leaf petiole length, leaf width, leaf number, fresh weight and dry weight of leaves) were significantly varied among the treatments. There was a significant difference in the diameter of beetroot among the treatments. Significant differences (P<0.05) were observed in fresh weight of beetroot and total plant among the treatments. Fresh weight of root yield and total yield of beetroot per plant were increased in 10 t/ha goat manure, 2 t/ha sugarcane molasses and 50% TSP (T4) and 10 t/ha goat manure, 3 t/ha sugarcane molasses and 50% TSP (T5) when compared to the control treatment (T1). The total yield of beetroot per m2 was 1,792.62 g in T4 and 1,402.68 g in T1. The root yield of beetroot was increased in T4 in comparison to T5. It can be concluded that 10 t/ha of goat manure with 2 t/ha of sugarcane molasses and 50% TSP could be applied for obtaining a high yield of beetroot in sandy regosol.
