Purpose. To reveal the peculiarities of leaf area formation and a structure of lentils variety ‘Antonina’ yield depending on the elements of cultivation technology: ino culation with nitrogen-fixing and phosphate-solubilizing microorganisms and the use of foliar growth stimulants. Methods. Field, laboratory. The experimental scheme included inoculation of seeds with nitrogen-fixing microorganisms (Ryzogumin), application of phosphate-solubili zing microorganisms (Polimixobacteryn and Biophosphoryn) into the row zone, and foliar feeding with a growth stimulator (Alga 600). Results. The results of studies of the leaf area formation peculiarities and the structure of lentils yield depending on the influence of cultivation technology elements are given in the article. It was found that the maximum indicators of the leaf area were formed by lentils in the flowering phase, which on average in the experiment was at the level of 37.5 thousand m2/ha, and in the control variant – only 32.0 thousand m2/ha. By inoculating the seeds with Rhyzogumin, applying phosphate-solubilizing biopreparation and foliar feeding, we obtained the maximum parameters of the leaf surface of lentil plants in the experiment. Thus, in the variant of inoculation with Rhyzogumin, application of Biophosphoryn and treatment with Alga 600 lentil plants formed a leaf area of 40.3 thousand m2/ha. However, due to the use of the phosphate-solubilizing biopreparation Polimixobacteryn and Alga 600 on the background of seeds inoculation with Rhyzogumin, the leaf area was formed at the level of 39.9 thousand m2/ha. Conclusions. When the seeds were treated with nitrogen-fixing microorganisms (Rhyzogumin) and phosphate-solubilizing bacteria (Polimixobacteryn and Biophosphoryn), the yield of lentils increased significantly. Thus, in the experimental plots in the variants with Ryzogumin + Polimixobacteryn the yield was – 1.64 t/ha, and in the combination Ryzogumin + Polimixobacteryn + growth stimulator Alga 600 the yield of lentils was – 1.90 t/ha. Seed inoculation had a positive effect on plant height. The best results were obtained when the seeds were treated with Ryzogumin in combination with Biophosphorin and Polimixobacteryn – 44.5 and 44.1 cm, respectively.

Установити особливості формування площі листя та структури врожаю сочевиці ‘Антоніна’ залежно від елементів технології вирощування: інокуляції азотфіксувальними й фосфатмобілізувальними мікроорганізмами та застосування позакоренево стимуляторів росту. Методи. Польові, лабораторні. Схема досліду передбачала інокуляцію насіння азотфіксувальними мікроорганізмами (Ризогумін), унесення в зону рядка фосфатмобілізувальних мікроорганізмів (Поліміксобактерин і Біофосфорин) та позакореневе підживлення стимулятором росту (Альга 600).Результати. У статті наведено результати досліджень щодо вивчення особливостей формування площі листя та структури врожаю сочевиці залежно від впливу елементів технології. У результаті проведених досліджень визначено, що у фазі цвітіння рослин сочевиці утворювали максимальні показники площі листя, яка в середньому по досліду була на рівні 37,5 тис. м2/га, а от на контрольному варіанті – лише 32,0 тис. м2/га. За інокуляції насіння Ризогуміном та внесення фосфатмобілізувальних препаратів і позакореневого підживлення отримали максимальні параметри листкової поверхні рослин сочевиці в досліді. Зокрема, у варіанті інокуляції Ризогуміном, унесення Біофосфорину та оброблення Альга 600 рослини сочевиці формували площу листя 40,3 тис. м2/га. А от у разі застосування на фоні інокуляції насіння Ризогуміном фосфатмобілізувального препарату Поліміксобактерин та Альга 600 була сформована площа листя на рівні 39,9 тис. м2/га.Висновки. За оброблення насіння азотфіксувальними мікроорганізмами (Ризогумін) та фосфатмобілізувальними бактеріями (Поліміксобактерин та Біофосфорин) урожайність сочевиці суттєво збільшувалася. Зокрема, у варіанті застосування Ризогумін + Поліміксобактерин урожайність становила 1,64 т/га, Ризогумін + Поліміксобактерин + стимулятор росту Альга 600 – 1,90 т/га. Інокуляція насіння позитивно вплинула й на висоту рослин. Ліпші результати отримано за оброблення насіння Ризогуміном у поєднанні з Біофосфорином та Поліміксобактерином – 44,5 і 44,1 см відповідно.
