Effect of phosphorus fertilizers used in different doses on cauliflower productivity

\nResearch has established that in order to obtain a high and stable yield with good taste qualities of cauliflower, it is recommended to use phosphorus of 175 kg/ha P2O5 against the background of N200 K100. At the same rates of application, ammophos is more effective than nitrocalcium phosphate fertilizer. In the article, the positive aspects of using Ammafos, Superfos, fertilizers at the rate of 175 kg per hectare in the cultivation of Cauliflower Casper F1 hybrid in the conditions of irrigated meadow-gray soil of Samarkand region, and the most optimal phosphorus nutrition norm is N200 K10 0 background Determined to be P175. From this, it was determined that the length of cauliflower heads is 14-16 cm, and the mass of cauliflower heads is 800-1100 grams.The effect of new type of phosphorus-retaining fertilizers on the growth and development, productivity and quality of the Cauliflower Casper F1 hybrid in the conditions of irrigated meadow-gray soils of Samarkand region, the effect of the phosphate component of these fertilizers on the amount of mobile phosphorus in the soil, the fractional composition of soil phosphates, and the intensity of phosphates is the first study of the researcher’s research.\n
