Abstract. Pre-sowing treatment of sunflower seeds in a magnetic field makes it possible to improve the sowing quality of seeds and increase the yield of sunflower without the use of mineral fertilizers and chemical plant protection products. Compared to other electrophysical methods, pre-sowing treatment of seeds in a magnetic field is a highly productive, energy-consuming, safe method for operating personnel and the environment. It has now been established that the yield and biometric indicators of agricultural crops depend on the dose of magnetic treatment. Therefore, the aim of the study was to determine the optimal energy dose for processing sunflower seeds in a magnetic field. An analytical expression has been obtained for determining the energy dose of sunflower seed treatment in a magnetic field. It contains all the operating parameters of seed treatment in a magnetic field. It has been established that the energy dose of sunflower seeds treatment in a magnetic field depends in direct proportion to the square of the magnetic induction and pole division and inversely to the speed of the seeds in the magnetic field. The carried out multifactorial experiment made it possible to determine the sunflower seeds germination energy and germination at various energy doses of treatment. This made it possible to determine the optimal mode of sunflower seeds treatment in a magnetic field. It was found that the optimal mode of pre-sowing treatment of sunflower seeds in a magnetic field is a magnetic induction of 0.065 T, four-fold re-magnetization, pole division 0.23 m, a seed velocity of 0.4 m/s, providing an energy treatment of 3.8 J‧s/kg. With the optimal treatment of sunflower seeds in a magnetic field, the germination energy increased by 28 %, the germination – by 24 %, and the yield – by 26 %.

The Imidacloprid insecticide, Gaucho 70 WS at 1.5, 2.5, 3.5, 4.5 and 5.5 g/kg seed was used as seed treatment and monocrotophos 40 WSC at 1120 ml/ha was applied as foliar spray on CB9 cotton cultivar to suppress aphid, whitefly and thrips, and impact on their natural enemies during 2008-2011 at the Regional Cotton Research Station, Dinajpur, Bangladesh. The activity of natural enemies, such as ladybird beetle, lacewing, syrphid, and spider population on the sucking pests attacking cotton cultivar CB9 and yield of cotton were recorded. Imidacloprid significantly reduced aphid, whitefly, and thrips population on cotton crops compared to untreated control or foliar spray of monocrotophos 40 WSC at 1120 ml/ha. Ladybird beetles, lacewings, syrphids, and spiders were abundant in the field but their population decreased in the treated plots compared to untreated control. The CB9 cotton cultivar produced significantly higher yield (1.73 t/ha) with a benefit cost ratio 12.47 when seeds were treated with Imidacloprid at 5.5 g/kg fuzzy seed. This study indicated that Imidacloprid (Gaucho 70 WS) used as a seed treatment may be suggested to the cotton growers for controlling sucking pests. Bangladesh J. Agril.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.
