Selection of hybrids and determination of planting time of ratoon broccoli crops in Uzbekistan

In Uzbekistan, the production of vegetables is much higher than consumption, but the range needs to be expanded. The family Brassicaceae plays an important role in the organization of healthy diet. Of special interest is broccoli, which is widely used in many countries, but hardly cultivated in Uzbekistan. The study to select the best hybrids and determine its planting time was conducted in 2015-2017. The subjects of the study were 7 hybrids of broccoli and 1 hybrid of cauliflower, and 6 planting dates. In the variety testing, the standard was Fiesta F₁. As a result of the study, it was established that Lucky F₁, Coronado F₁ and Strombili F₁ entered the fruiting stage first (97 days after the emergence of seedlings). Strombili F₁ demonstrated the longest fruiting period (70 days), Hallmark F and Belstar F₁ - the shortest one (39-41 days). Hallmark F₁ was the most productive hybrid, the yield of the central heads exceeded Fiesta F₁ by 64.4%, and the total - by 46.65. Of the 6 tested planting dates from July 25 to August 15, the largest harvest was obtained during the period of 5-15 July. The optimal dates for the summer planting were 5 and 15 July. The last acceptable planting date was 5 August. To ensure the conveyor flow of fresh products in autumn, broccoli should be planted from 25 June to 5 August.
