Effect of planting density and fertigation on growth, flowering and yield in processing varieties of tomato

Abstract

The var. Abhinav was recorded the lowest number of days to 50% flowering (59.40 days) with highest fruit yield per plot (970.24 kg). Planting density at 75 cm x 40 cm (S2) recorded significantly the lowest number of days to 50% flowering (59 days) followed by 60 cm x 60 cm (S3). The highest number of days to 50% flowering (61.70 days) was recorded by 120 cm x 40 cm. Application of 180N: 90P: 90K kg per ha (F3) recorded the highest plant height (133.30 cm), canopy spread (40.74 cm), leaves (40.21), highest number of days to 50% flowering (66.01 days) and fruit yield per plot (1066.04 kg) followed by 150N: 75P: 75K kg per ha (F2). The lowest readings of these parameters were recorded by the application of 120N: 60P: 60K kg per ha (F1). Among three way interactions, the lowest number of days to 50% flowering was recorded by the combination of variety Abhinav + 75 cm x 40 cm (S3) + 120N: 60P: 60K kg per ha (54.26 days).
