INFLUENCE OF SEEDING RATE AND FERTILIZATION ON THE MORPHOMETRIC INDICATORS AND YIELD OF SEEDING BUCKWHEAT (FAGOPYRUM ESCELENTUM MOENCH)

Abstract

The main objective of this study was to determine the influence of sowing rate and fertilization with macroelement fertilizers on the morphometric indicators and yield of buckwheat. The experiment was carried out in 2021-2022 at Daiva Kandratavičienė farm, in a production field in Anykščiai district, Bičioniai village. The experiment was carried out in 4 repetitions, which were randomly arranged. In a two-factor experiment, 3 sowing rates and 2 fertilization options were studied. The soil of the experimental field is Luvisols, sandy loam. Before the installation of the experiment, soil tests were carried out, the soil had low acidity (pH-6), low humus content (1.9%), low phosphorus content (69 mg kg-1), medium potassium content (139 mg kg-1). Pre-sowing - winter wheat. Spring tillage was carried out on April 21, at a depth of 5 cm. On May 15, the field was sprayed with glyphosate, and on May 25, sowing was done. Fertilizers were applied locally.

In the experiment, the highest yield of sowing buckwheat, plant height and the number of inflorescences on the plant, which were significantly different, were found in the variant in which (3.5 million ha-1) seeds were sown and fertilized with N₁₂ P₃₆ K₆₈.. The lowest indicators were recorded in the test variants, where buckwheat was sown (2.5 million ha-1), , fertilization did not give significant differences.
