Nutrient uptake and yield of cherry tomato under NPK fertilization

Abstract

The investigation was conducted to assess the effect of levels of N, P and Kon nutrient uptake and yield of cherry tomato (Solanum lycopersicum var. cerasiforme) at the research farm of the department of Soil Science and Water Management, Nauni, Solan-Himachal Pradesh during kharif seasons of 2014 and 2015. The results revealed that the maximum fruit yield and nutrient contents in the fruit, shoot and root were found in the treatment-T6 comprising of 125% recommended dose of NPK( RDF) followed by 100% RDF (T5) and minimum levels were found in the treatment without fertilizer (T1- control). The maximum uptake of N (90.06 kg ha-1), P (13.19 kg ha-1) and K (74.50 kg ha-1) by cherry tomato was recorded under treatment T6, whereas, the minimum uptake of N (69.66 kg ha-1), P (7.51 kg ha-1) and K (54.20 kg ha-1) by cherry tomato was recorded under T1 (control) treatment. The maximum uptake of Cu (316.09 g ha-1), Fe (585.51g ha-1), Zn (85.68 g ha-1) and Mn (145.61 g ha-1) by cherry tomato was recorded under treatment T6, whereas, the minimum uptake of Cu (253.73 g ha-1), Fe (462.40 g ha-1), Zn (67.97 g ha-1 ) and Mn (115.95 g ha-1) by cherry tomato was recorded under T1 (control) treatment.
