increasing yields and protection of agricultures against diseases, A.K. Zlotnikov,

Influence of Albit on vegetable marrows (squash) (Cucurbita pepo L.) was examined
in trials of All-Russia Institute of Vegetable Selection and Seed Breeding (Moscow oblast)
in 2001 on bunchy squash var. Gribovskiy (white squash). Seedlings of squash were
planted according to scheme 100x100 cm, area of plots was 50 m², with triple replication.
Squash was harvested in its technical ripeness. In result of treatment with Albit, squash
acquired improved turgor and drought resistance. Also, Albit accelerated beginning of
blossoming by 4-5 days, and increased number of seed-buds per one stem up to 4-6 (3-4
in control sets).
Yield of vegetable marrows in control sets was 402 centners/hectare on average. Albit
provided yield increase by 121 centners/hectare (30.1%). Foliar sprayings
appeared to be crucial for yield increase: only presowing seed treatment with Albit (2 ml/kg)
without foliar sprayings provided yield increase of just 4.7%. According to results of All-Russia
Institute of Vegetable Selection and Seed Breeding, squash gave one of the highest relative
yield increases in response to Albit treatment among all other tested vegetables (cucumber,
tomato, pepper and eggplant).
