Distancia entre plantas y dosis de nitrógeno y potasio en sandía sin semillas fertirrigada

The objective of this work was to evaluate the effects of N and K2O doses, applied by a drip fertigation system, and of distances between plants on the productivity of the Shadow hybrid of seedless watermelon. The experiment was carried out from August to October 2008, at Tupã, SP, Brazil. Four doses of N + K2O (79.8 + 106.7, 106.4 + 142.2, 133.0 + 177.7, and 159.6 + 213.2 kg ha-1) and four spacings between plants (0.5, 1.0, 1.5, and 2.0 m) were evaluated in 2.0-m spaced rows. A randomized complete block design with split plots and three replicates was used. Evaluated variables were: N and K ...
