IMPACT OF PLANT GROWTH REGULATORS AND WEIGHT OF A BULB FOR PLANTING ON YIELD OF SHALLOT GREENS AT DISTRACTION
An increase of yield and marketability of shallot greens at distraction due to the technology of growing regulators of plant growth and bulbs of various fraction was investigated at the department of fruit growing, storage and processing of agricultural product of Perm State Agricultural Academy in 2014-2015. Three-hours soaking of shallot bulb in the solutions of growth regulators Energia-M, Vigor-Forte (2 grams per litre of water) before planting accelerates sprouts emergence by 3-4 days compared with the control bulbs ( the dry ones), this raises the indicators of plant habitus (a number of shoots, leaves, their assimilating surface), promotes their common yield and their marketability. At using for planting for distraction the small bulbs (of 8.6-10.0 grams), an increase to plant weight and that to yield comprises (according to experiment variants) 132-249% and 129-244%, product output is 10.1 kilos per 1 square metre in average. When large bulbs (of 20.8-24.5grams) are used for planting an increase in plant weight comprises 42-103%, that in yield - 44-11%. Yield was considerably greater - from 10.5 to 15.4 kilos per square metre, and according to experiment variants in average - 13.3 kilos per square metre. Correlation between weight of bulb planted and its yield at harvesting is a close one (0.893± 0.013). However, it is necessary to take into consideration a great outgo of planting material per unit of area and its cost at planting of a greater shallot planting bulbs.
