\u3000Last year, the worldwide spread of the new coronavirus had a major impact on our lives. New lifestyles such as avoiding the \"three densities,\" wearing masks, and disinfecting hands were introduced, as well as new work styles such as telework and remote conferencing.<\/p>\n\n\n\n

\u3000In the agricultural sector, the decrease in demand for agricultural and livestock products for restaurants and the shortage of foreign workers have had a variety of effects, and various measures are being taken by individual producers, local communities, and the national government. With no end in sight, new initiatives such as \"With Corona\" and \"After Corona\" will be necessary in the future.<\/p>\n\n\n\n

\u3000In 1981, our \"LP Coat\" was first shipped to Ishikawa Prefecture as a raw material for BB fertilizer (for additional fertilizer), and the following year, in 1982, our \"LP Compound\" made from \"LP Coat\" was shipped to Okayama Prefecture for direct seeding in dry paddy fields. This was truly the start of \"whole paddy rice cultivation with basal fertilizer. Since then, we have continued to build up our technology with the support of our research and distribution partners, and have continued to do so up to the present day.<\/p>\n\n\n\n

\u3000Today, \"coated compound fertilizers\" are produced and sold by various domestic fertilizer manufacturers, and they are now recognized as \"one-shot fertilizers\" in the agricultural industry. The percentage of rice paddy cultivation using these fertilizers is estimated to be more than 50% in terms of rice paddy area.
\u3000This is the so-called \"new normal\" in paddy rice cultivation.
\u3000However, with the recent intensification of weather fluctuations, changes in soil composition over the years, renewal of paddy rice varieties, and changes in demand from labor-saving to yield-increasing technologies, \"paddy whole-plant fertilizer cultivation\" is not always a \"one-shot\" solution.<\/p>\n\n\n\n

\u3000It has been about 40 years since the \"Total Rice Fertilizer Cultivation\" started. Last year, we started to study the matching of \"total fertilizer cultivation technology\" and smart agriculture, although we are late to the game. We are committed to creating a \"new normal\" that can contribute to agriculture through fertilizers, with the goals of responding to climate change and meeting the demand for technology to increase yields.<\/p>\n\n\n\n

\u3000In closing, I would like to wish you a Happy New Year and ask for your continued patronage of this issue of \"Agriculture and Science\".<\/p>\n\n\n\n

Use of Fertilizer with Regulated Fertilizer in Spring Sown Onion Cultivation<\/h2>\n\n\n\n

Fukushima Prefectural Agricultural Center

Introduction<\/h3>\n\n\n\n

\u3000In areas in Fukushima Prefecture where evacuation orders have been lifted and in areas affected by the tsunami, there are few farmers who have returned to their farms, so a small number of people are required to manage large plots of land in order to maintain local agriculture. Land-use type open-air vegetables such as onions have been introduced to the region as a new crop to improve the profitability of management entities, and the onion cultivation area in the Hamadori region has expanded rapidly, starting from 30 a in FY 2015 to 2,742 a in FY 2020.<\/p>\n\n\n\n

\u3000Onion cultivation in the prefecture is divided into two types: fall sowing, in which onions are sown in August or September and planted in October, and spring sowing, in which onions are sown in January and planted in March, with the harvest period from June to July. In spring sowing, the period from planting to harvest is about three months, and generally no additional fertilizer is needed in the field. However, in fields with low soil fertility, fertilizer runoff during the growing season can cause nitrogen deficiency, leading to poor growth and lower yields.<\/p>\n\n\n\n

\u3000In this study, we selected a leaching type of controlled-release fertilizer suitable for spring-sown onion cultivation and attempted to determine whether a combination of conventional fertilizer and controlled-release fertilizer could produce the same yield as conventional fertilizer with a reduced basal fertilizer.
\u3000This test was conducted as a commissioned test for the Fukushima Plant Protection Association's \"Test and Research Project on New Pesticides, etc.\".<\/p>\n\n\n\n

2. Testing Method<\/h3>\n\n\n\n

(1) Outline of cultivated species<\/h4>\n\n\n\n

\u3000The trials were conducted in open fields (gray lowland soil) at the Fukushima Prefectural Agricultural Center in Koriyama, Fukushima Prefecture, for two years, 2018 and 2019. The seedlings were sown in 448-hole cell trays on January 24, 2018 and January 18, 2019 in a glasshouse with one inner curtain, and the temperature was set so that the minimum temperature would not fall below 10\u00b0C. The number of emerged leaves was 2.5 to 3. Minoru Mega Soil (Minoru Sangyo Co., Ltd.) was used as the soil medium, and Tomy Liquid Fertilizer Black (Katakura Co-op Agri Co., Ltd.) was used as the fertilizer. Base fertilizer was applied on the day of planting.<\/p>\n\n\n\n

\u3000Planting was done on March 31, 2018 and April 2, 2019 using a four-row fully automatic transplanter. The planting density was 26,667 plants\/10a (4 rows planted per row, row width 120 cm, row spacing 20 cm, and plant spacing 10 cm). The date of downfall, when 80% of the plants had fallen over the ground, was July 4 and July 15 in 2018 and 2019, respectively. Harvesting was conducted simultaneously 7 days after the toppling date, on July 11 in 2018 and July 22 in 2019. Harvests were dried and stored in pipe houses covered with shading material with a shading rate of 501 TP3T.<\/p>\n\n\n\n

2) Fertilizer selection (2018, 2019)<\/h4>\n\n\n\n

\u3000Since onion tuberization is initiated by long-day conditions, it is important to allow sufficient growth of the stem and leaves by then. In addition, it is necessary to consider the negative effects of insufficient nitrogen at the start of enlargement, which results in poor ball enlargement, and too much nitrogen, which delays enlargement and tends to produce rotten balls (Kato, 1963; Iwata, 1959). In spring-sown cultivation of \"Momiji No. 3\" in Koriyama, stem and leaf growth was vigorous from mid-May, and around June 22, the number of emerged leaves reached 12 and enlargement progressed (Figs. 1-3).<\/p>\n\n\n

\u3000Fertilizer application rates for the test plots are shown in Table 2. Fertilizer was applied on the planting date. In the conventional zone, 15 kg of nitrogen, 30 kg of phosphate, and 15 kg of potash were applied per 10 a. In the other zone, half of the total nitrogen content was fertilized with a fertilizer with a controlled fertilizer. In the other areas, half of the total nitrogen was fertilized with a fertilizer with regulated fertilizer, and the other half with the conventional fertilizer, S604 phosphonitrite and potassium sulfate, together with 20% phosphorus and potassium sulfate, the amounts of fertilizer applied to the field were 15 kg of nitrogen, 30 kg of phosphoric acid, and 15 kg of potassium per 10 a.<\/p>\n\n\n

3) Investigation of the effect of fertilizer application regulating fertilizer on fertilizer reduction\uff082019)<\/h4>\n\n\n\n

\u3000Because of the high fertilizer efficiency of fertilizer application, the test plots in Table 2 were set up to confirm the effect of fertilizer reduction of S604 phosphonitrite and potassium phosphate, the conventional fertilizer used as the base fertilizer. L30 (linear elution) and S20H (sigmoidal elution) were used as elution types.<\/p>\n\n\n\n

\u3000In the L30 reduced fertilizer and S20H reduced fertilizer test plots, half of the total nitrogen was fertilized with fertilizer with regulated fertilizer, and the conventional fertilizer, S604 phosphorus nitrate and potassium sulfate, was reduced by 30%, and the amount of fertilizer applied to the field together with 20% phosphorus and potassium sulfate was 13 kg for the nitrogen component, 30 kg for the phosphoric acid component and 15 kg for the potash component per 10 a. The fertilizer was applied in the main field.<\/p>\n\n\n\n

\u3000Based on these results, M-Coat L30, L40, and S20H were the desired elution types, eluting in May, when weather and soil conditions are assumed to make it easier for the base fertilizer effect to wear off, and eluting at 80% in early June.<\/p>\n\n\n\n

2) Effect on onion growth<\/h5>\n\n\n\n

\u3000In 2018, grass height was minimum in the L40 section and maximum in the conventional section on May 11, but by June 1 there was no difference. No significant differences in number of leaves emerged and leaf sheath stems were observed throughout the period (Table 3). 2019 showed no significant differences in grass height, number of leaves emerged, and leaf sheath stems throughout the period in all sections (Table 4).<\/p>\n\n\n

3) Impact on onion yield<\/h5>\n\n\n\n

\u3000No significant differences were observed in ball weight, ball diameter, standard ball percentage, outer partial ball percentage, and rot percentage at harvest and one month after harvest in all the sections in both 2018 and 2019. Within-specification yields ranged from 4.7 to 5.0 t\/10a in 2018 and 6.1 to 6.5 t\/10a in 2019 (Tables 5 and 6).<\/p>\n\n\n

Consideration<\/h3>\n\n\n\n

\u3000The conventional fertilizer used in this study, phosphorus nitrate-ammonium potassium S604, is composed of approximately 60% ammonia nitrogen and 40% nitrate nitrogen, and ammonia nitrogen lasts for approximately one month, while nitrate nitrogen may be lost in a short period due to rainfall, but it is estimated to last for approximately 15 days. Therefore, it is assumed that the effect of basal fertilizer tends to wear off in May, and the fertilizer used in this study, Emcote, a controlled-release fertilizer, made it possible to stably supply nitrogen components in May, when the above-ground area increases, and there was no effect on yield or rot rate. This suggests that there was no excessive supply of nitrogen during the fertilization period.<\/p>\n\n\n\n

Summary<\/h3>\n\n\n\n

\u3000The types that leached in May, when the base fertilizer effect is expected to be easily broken due to weather and soil conditions, and leached 80% in early June were Emcote L30, L40, and S20H. When the fertilizer M-Coat was used for half of the total nitrogen content of 15 kg\/10a, and the conventional fertilizer S604 was used for the other half, there was no effect on growth and yield regardless of which leaching type of M-Coat was used. Furthermore, when the nitrogen content of conventional fertilizer was reduced by 30% and M-Coat L30 or S20H was used in combination with the conventional fertilizer, the yield was equivalent to that of the conventional fertilizer.<\/p>\n\n\n\n

\u3000As a result of the above, when a slow-release fertilizer was placed immediately after purchase and a commercial tablet fertilizer with a fertilizing effect of about one month was used, eight tablets per pot (1.5 g\/pot for each of the three elements) was the appropriate amount. In the case of liquid fertilizer application, weekly application of [20-20-20] at a dilution of 500 times, N-400 ppm was effective. Considering cost and availability, [20-20-20] is more appropriate than [10-30-20].<\/p>\n\n\n\n

(2) Combination of growing container and soil and seedling growth (Experiment 3)<\/h4>\n\n\n\n

\u3000For potted seedlings planted on May 9, leaf color (SPAD value) did not differ among containers, but was influenced by the substrate. In particular, the SPAD value of cotyledons on May 21 was significantly lower in Veravon. Even on June 13, when the cotyledons had dropped off, there were significant differences among the soils (Table 2). Grass height was affected by both container and soil on June 13 and June 27, but only by soil and not by container on July 4. Although grass height was inferior in the Veravon area on all survey dates, it increased with the number of growing days, indicating that the growth was good (Table 3). No difference was observed in the date of first flowering among the different containers and soils (data omitted).<\/p>\n\n\n

(3) Dry weight of long tailored pot seedlings at completion (Experiment 3)<\/h4>\n\n\n\n

\u3000The flowering of each section of containers and soils was ready, and the outdoor installation was set for July 7, the middle day of the Iriya Morning Glory Festival. The dry matter weight of the long-tailored potted seedlings at the time of shipment was reduced to half that of the conventional combination of polyethylene pots and red soil by using Kuntan and Veravon (Fig. 3).<\/p>\n\n\n

(4) Outdoor placement of long-tailored potted seedlings with combustible materials and the number of daily blooms (Experiment 3)<\/h4>\n\n\n\n

\u3000The number of daily blooms in paper pots made of combustible material in combination with either kuntan or veravon as a substrate was equivalent to that of the conventional material until August 9 (Figure 4).<\/p>\n\n\n

(5) Outdoor management of long tailored potted seedlings using combustible materials and their growth and flowering (Experiment 3)<\/h4>\n\n\n\n

\u3000The plant height of the combination of Kuntan and Bellavon in paper pots on July 26 and August 1 and 10 was similar to that of the conventional polypropylene pots + red soil mixture. The distribution of flowering by height above ground was also similar, but on July 26 and August 1, \"Red Lion\" tended to flower at relatively low height (less than 1.0 m above ground) and \"Purple Lion\" at 1.0 m above ground. The flowers were almost uniformly distributed at each height (Fig. 5, Photo 2).<\/p>\n\n\n

Summary<\/h3>\n\n\n\n

\u3000We focused on the number of blooms during the first two months after purchase of the four-plant, paper-lantern style morning glories, a standard at the Iriya Morning Glory Festival, and investigated fertilization methods after purchase. The results showed that (1) slow-release fertilizer with at least 1.5 g each of the three elements at the time of purchase and (2) weekly application of a liquid fertilizer (N-400 ppm) containing equal amounts of the three elements after purchase were effective.
\u3000We also attempted to commercialize long pot seedlings of morning glory induced by string, and proposed a plant decoration that can be disposed of entirely as combustible waste after use by using a combustible cultivation container and soil. The paper pots used as growing containers showed good growth as well as conventional polypropylene pots, and the number of days of flowering was not affected. In addition, by filling the paper pots with kuntan, it was possible to reduce the weight by 50% or more compared to conventional pots, and no effect on growth and flowering was observed.<\/p>\n\n\n\n
