Rapeseed<\/strong> ranks third among oil crops. Its gross production is about 33-35 million tons<\/strong>, and oil production reaches 9.8%<\/strong> of world volumes. Rapeseed is grown in more than 30 countries of the world, 30 million hectares, or 10.5% of all areas of oil crops are allocated for sowing. In Europe, this crop occupies almost 4 million hectares. Thus, in Germany, one of the leading rapeseed countries, 10-11% of the total sown area is allocated to it.<\/p>\n Winter rape<\/strong> is a plant of a temperate climate, light- and moisture-loving. It, like every crop, is characterized by optimal values and biological minimums of the main agrometeorological parameters: solar radiation, heat and moisture. The highest yield of rapeseed is formed when the needs of plants are fully met, under optimal values of environmental factors, a large part of which is meteorological values.<\/p>\n Rape requires<\/strong> fertile soils with medium humus content and a neutral or slightly acidic reaction of the soil solution. The most suitable for its cultivation are dark gray and gray forest soils, black soils, sod-podzolic, sod and sod-loamy soils with a light and medium loamy texture.<\/p>\n Nutrient supply is a determining factor for the good development of rapeseed, its winter hardiness, resistance to diseases and pests. For the formation of 1 ton of crop, rapeseed takes from the soil: nitrogen – 45-80 kg; phosphorus – 18-40 kg; potassium – 25-100 kg; calcium – 30-150 kg; magnesium – 5-15 kg; sulfur – 30-45 kg.<\/strong><\/p>\n Rapeseed absorbs about 15-25%<\/strong> of nutrients from soil reserves, and the rest should be applied in the form of organic and mineral fertilizers.<\/p>\n Full use of mineral nutrients by plants is possible only if all elements are provided. The lack of one of them inhibits the assimilation of others and ultimately negatively affects the yield.<\/p>\n Like all cruciferous plants<\/strong>, rapeseed has a high need for nitrogen<\/em><\/strong>. It is manifested from the beginning of vegetation to budding. Of the total amount of nitrogen in the fall, plants use about 20%, 36%<\/strong> at the beginning of vegetation recovery, 31%<\/strong> at the beginning of flowering, and 10% at the end of flowering. Based on this, it is advisable to apply no more than 25% (25-30 kg\/ha)<\/strong> of nitrogen from the total need for winter rapeseed in autumn.<\/p>\n In order to avoid nitrogen deficiency in rapeseed, we recommend using Wonder Leaf Violet fertilizer (N:P:K-30:10:10 + SO3-15, Mo-0.5, w\/w %).<\/strong><\/p>\n Phosphorus <\/em><\/strong>is necessary for the development of a good root system, increase of seed productivity, acceleration of maturation, prevents plant dormancy. This nutrient is obtained mainly from soil reserves (70-80%). If the phosphorus content is lower than the specified norm, there is a need for its additional application.<\/p>\n To avoid phosphorus deficiency, we recommend using Wonder Leaf Blue<\/a> fertilizers (N:P:K-10:53:10 + Zn-2 chelate , w\/w %)<\/strong>, or Wonder Leaf P 30<\/a> (N:P-4:30 + B-0.5, Zn -0.5 chelate, amino acids-1, organic acids-4, w\/w %).<\/strong><\/p>\n Rapeseed plants can absorb up to<\/strong> 300 kg of K 2 <\/sub>0<\/strong> per hectare, and during the autumn period – up to 70 kg<\/strong>. Plants need the most potassium during autumn development and before flowering. The lack of this element delays the growth of stems, the development of the root system, reduces the frost resistance of crops, the oiliness of seeds, increases the tendency to lay down, and contributes to the appearance of reddish-brown spots on the leaves. Sufficient provision of plants with potassium enhances nectar production.<\/p>\n To avoid potassium deficiency, we recommend using Wonder fertilizer Leaf Red<\/a> (N:P:K-10:20:30 + B-2, w\/w %)<\/strong>; no less important for the formation of a high- oil rapeseed crop are trace elements.<\/p>\n Manganese <\/em><\/strong>Wonder Leaf Mono Mn 11<\/a> (Mn-11% chelate)<\/strong> increases winter resistance, affects the accumulation of sugars in plants and participates in nitrogen and phosphorus metabolism.<\/p>\n Fertilizers containing boron:<\/strong> Wonder Leaf Mono B 11<\/a> (B-11%)<\/strong>, or Wonder Leaf Mono B 120<\/a> (B-9%)<\/strong>, or Wonder Leaf Pink<\/a> (B-20%)<\/strong> promotes the growth and development of the root system, growth points, increases the accumulation of sugars and other high-energy substances, ensures their transportation to the root neck. It also improves frost and winter resistance of the plant and wintering as a whole, significantly affects the processes of pollination and fertilization, accelerating the germination of pollen and contributing to the formation of the generative apparatus of plants.<\/p>\n Its deficiency inhibits protein synthesis, slows down plant growth, reduces the number of pods on a plant and seeds in pods, and the quality of seeds deteriorates due to a decrease in oil content. Another important function of sulfur in plant metabolism is to increase resistance to fungal pathogens.<\/p>\n
