EFFECTS OF NUTRIENT SUPPLY ON THE YIELDS OF MILLET PUBLISHEDB. CZINEGE, Z. FUTÓ email@example.com
In our study we have examined the reaction of millet to different nutrient supply level. The goal of the experiment was to elaborate an efficient and economical fertilisation technology that can be recommended for millet producers or those wanting to grow this plant. Millet is among the most important cereals in the oriental parts of the world. The main millet-producing countries can all be found in Asia.. In Asia and Africa millet is one of the most important cereal plants: 400 million people consume it on a daily basis. The experiment was implemented in Szarvas, the Galambos experimental site of Szent István University. The soil type was phaeozem with deep-laying carbonates. Four levels of nutrient supply was involved: 0-30-60-90 kg/ha N+PK. Millet were sown in the springs of 2018 and 2019 in four repetitions. The size of each parcel was 18.55 m2 and all parcels receive the same agro-technical solutions. The largest yields were reached at the highest level of nutrient supply in both years (2.85 t/ha and 4.05 t/ha in 2018 and 2019, respectively). However, no remarkable increase could be detected regarding the average yield. Different precipitation conditions resulted alterations in the amount of yields. Height of the plants (in 2019), relative chlorophyll content and the average number of grains per booth all reached the highest values in case of 60 kg/ha N+PK treatment. Average yield and thousand grain weight were at their peak when the highest active fertilising substances were applied. As a summary it can be concluded that average yields increased as a result of heightened nutrient supply level, although not in an extent that would have justified the recommendation of the highest level of fertilisation. Taking into account the results received applying 30 kg/ha N, 18 kg/ha P2O5, 30 kg/ha K2O or 60 kg/ha N, 36 kg/ha P2O5, 60 kg/ha K2O proved to be the most economical.
