Nitrogen fertilizer, SPAD, increasing doses, stagesAbstract
The study was conducted in areas of Granja Santa Inés, the experiment was based on the application of nitrogen fertilizer from two sources of nitrogen (N), 50% mineral and 50% organic; the experimental design was completely random blocks, four increasing doses of N (0-225-450-675 kg N ha-1) were evaluated. For vegetative variables the following characteristics were valued: fresh matter, chlorophyll, fruit number, fruit length, fruit width and for production variables: yield; 30% of the total N was applied during the first stage, 50% during the second stage and 20% during the final stage; for data collection was executed at the end of each stage at 37, 67 and 97 days after transplantation (DDT). For fresh matter accumulation data the highest weight was obtained at 97 days at a dose of 675 kg N ha-1 obtaining a total weight of 9 455.46 kg ha-1; while for the chlorophyll variable the highest value recorded in the same days was obtained with an average of 79.8 SPAD units. In performance, the best result was recorded at 97 days in treatment 4, with 4 005.31 kg ha-1
