Effects of irrigation (water stress), timing of N application, boron rates and transplant characteristics on growth and development, maturity and yield of cauliflower


  • To evaluate the effects of varying the amount of water stress (irrigation) during early stages of growth of cauliflower plants, and/or before and during the time of curd initiation, or subsequent growth, maturity, and yield.
  • To measure the effects of varying the time of application of four nitrogen fertilizer sources (solution 32, urea, ammonium nitrate, and calcium nitrate) on growth, maturity, nutrient composition, and yield of cauliflower grown with adequate and uniform irrigation applications.
  • To determine the effects of varying the nitrogen rates on growth and yield of cauliflower.
  • To study the effects of rates of boron to the soil on growth and yield of cauliflower grown with differential total amounts of water (line-source irrigation).
