Macronutrients in grafted cucumber in areas with gall nematodes. Grafting is an often recommended technique for cucumber culture in areas infested with gall nematodes. This study aimed to evaluate the content of macronutrients in grafted cucumber in two rootstocks on soil infested with Meloidogyne incognita race 2 or Meloidogyne javanica, since they may decrease the effectiveness of water and nutrient absorption. One evaluated 9 treatments (factorial 3x3: nongrafted hybrid cucumber Tsuyataro, grafted on squash hybrid Shelper or grafted on squash hybrid Excitte Ikki x without inoculation, inoculation with M. incognita or M. javanica), in a randomized blocks design, with 4 replicates and 6 plants per plot. The characteristics evaluated were: macronutrient content at 72 days after transplantation and macronutrient content at the end of the cycle (99 days after transplantation). The nutrient contents evaluated didn’t differ according to the nematode species (with or without inoculation), however, there’re differences with regard to the rootstocks, with higher values of phosphorus and potassium in grafted plants and higher values of magnesium, calcium, and sulfur in nongrafted plants at the end of cycle.
