“…An even better and more specific picture of the effect of fertilizer placement is obtained when the results of all experiments conducted at the Sugar Beet Research Centre are considered (e.g. Erjala 1986, Raininko 1988), comparing placement with broadcasting (Table 10). When evaluating the figures, one should take into consideration the fact that the number of trials and experimental fields varied from one year to another.…”

“…The sugar beet was sown to stand, at a seed distance of 15 cm and row distance of 48 cm. The variety used was mostly Salohill in 1985 and1986; in some trials the cultivar Ovatio was also used.…”

“…Only early sowing can prevent some of the valuable growth period from being lost unnecessarily by waiting for the soil to dry adequately for seed bed preparation and sowing. To enable early sowing and to avoid soil compaction, develop-ment of a one-pass method was started in the early 1980 s at the Sugar Beet Research Centre. In this method, seed bed preparation, fertilization and sowing are done simultaneously (Raininko 1981, 1988, Erjala 1984, Erjala & Raininko 1985, using a fertilizer drill designed and built specifically for this purpose. A single-disk bill was initially used as the fertilizing bill, but very soon, in 1983, it was replaced by a thin bill with a stiff spring tine bill.…”

In 1982—1990, the Sugar Beet Research Centre conducted a total of 68 fertilizer placement trials. The present paper deals with 23 trials from five field experiment series. In the evaluation of the results, other experiments conducted at the Sugar Beet Research Centre have also been referred to. The field trials were conducted on experimental farms of the Sugar Beet Research Centre and of sugar factories. The soil type of the experimental fields varied from compact clay to finesand. The soil pH was high (6.7 —7.4) and the nutrient status good. The fertilizer used was an Na-containing compound fertilizer (N 13 %, P 6 %, K 9 %, Na 6 % in 1982—1987; N 15 %, P 6 %, K 8 %, Na 5 % as from 1988). The fertilizer was applied with a fertilizer drill. A disk bill was used in 1982—1983; thereafter a thin spring tine bill was used. Placement of fertilizer 3—6 cm to the side and 3 cm below the seed increased the root yield of sugar beet by 5—6 %, on an average, as compared to broadcasting. The yield increase ranged from 0 to 24 %. The yield increase from fertilizer placement correlated negatively with the sugar beet yield level. The nutritional status and humus content of soil, and soil type did not affect the yield increase from fertilizer placement. The seed bed preparation one-pass power harrow or conventional method had no significant effect on the yield increase from fertilizer placement. Increasing the level of fertilizer reduced the yield increase from fertilizer placement in some of the trials. This was not always the case, however. Placement usually gave a slightly higher sugar content than did broadcasting. Placement reduced the potassium content of the beet slightly and increased the extractability of sugar. As compared to broadcasting, placement increased the recoverable sugar yield relatively slightly more than the root yield. Placement of the fertilizer 3 cm to the side (3 or 6 cm below the seed) yielded a better result than placement 9 cm to the side of the seed. The depth of placement did not affect the yield. In most trials, placement of the fertilizer reduced the plant population only slightly as compared to broadcasting. The harmful effect in these trials was not significant even with the smallest distance from the seed, i.e. 3 cm. In practice, placement too close was shown to inhibit or to retard germination of the beet. It is therefore recommended that the fertilizer be placed 5—6 cm to the side and 3—4 cm below the seed.

“…Manganese helps in the production of enzymes used for metabolism of proteins and fat. Application of manganese @ 25-30 kg ha -1 together with compound fertilizer increased the average root yield by 2.0 t ha -1 (+7%) compared to manganese-free compound fertilizer (Erjala, 1986). Mekki (2014) reported that Manganese as sole treatment increased root length and diameter as well as fresh root weight of sugar beet.…”

Nutrient Management in Sugar Beet: A Review

Sugar is an important source of energy for the human body although it receives blame for many health problems, without it, the body would cease to function properly. Nearby thirty percent of the world sugar comes from sugar beet. Production of sugar beet globally spans diverse regions with a wide range of climatic and agro-ecological regions which shows exclusive management challenges. Fertilizer or nutrient management is one of the practices that associate with fertilizer use efficiency and production of the crops including sugar beet. As the nutrient management interacts with different agro-ecological areas and soils, the fertilizer recommendations and management have become regional and site-specific. Maximizing beet and sugar yields, the knowledge of the management of the fertilizers or nutrition is very essential. This article is to understand the impact of different fertilizers in different management practices including the major nutrients of the crop, fertilizer rate, timing, and method of application either solely or in a mixture or integrated manner with reviewing diverse research experiments. Moreover, it will help to approach future strategies and needs for making the production of sugar beet as a cost-effective crop with new improving management technologies for the farmers.
