Abstract
Tomato cv.
Strain B2 was direct-seeded in the field at New Halfa for two seasons to study the effects of in-row spacing at 20, 40 and 60 cm and levels of nitrogen at 43, 86 and 129 N kg ha-1 as urea, on yield and some quality attributes of tomato.
Direct-seeded tomatoes did not respond to nitrogen application but significantly responded to in-row spacing.
Reducing the in-row plant spacing from 60 to 40 cm resulted in a total yield increase of 24% in the first season and 38% in the second season.
Further reduction in spacing from 60 to 20 cm resulted in a total yield increase of 43% in the first season and 75% in the second season.
Closer spacing of 20 cm also reduced the numbers of sun-scalded fruits compared to 60 cm spacing.
Other fruit quality aspects such as TSS and cracked fruits were not significantly affected by either the in-row plant spacing or nitrogen fertilizer.
