EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON THE GROWTH AND YIELD OF TOMATO (Lycopersicon esculenlum)

Abstract

A field experiment was conducted at the research farm of Sher-e- Bangla Agricultural University, Dhaka, during November 2011 to March 2012 to study the effect of integrated nutrient management on the growth and yield of tomato. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replication of each treatment. The unit plot size was 6m2 (3mx2m). There were 9 treatment combinations in the experiment comprising 9 levels of N (180 kg/ha from Urea , 155 kg/ha from Urea + 25kg/ha from CD. 130 kg/ha from Urea + 50kg/ha from CD, 105 kg/ha from Urea ± 75kg/ha from CD, 80 kg/ha from Urea + 100kg/ha from CD, 55 kg/ha from Urea + 125kg/ha from CD, 30 kg/ha from Urea + 150kg/ha from CD) and single level of P & K.( 25kg P/ha from TSP + 60kg K!ha from MP). The maximum plant height (67.03cm) was recorded from T 5 treatment consisting of 80 kg N/ha from Urea +100 kg N/ha from CD and the minimum plant height (47.50 cm) was recorded from T 9 treatment i.e. control condition. The highest and lowest number of leaf per plant was 98.89 and 61.59 recorded from 1 4 and T 9 treatment respectively. The highest and lowest no. of fruit./plant was 67.07 and 38.51 recorded from T 5 and control treatment respectively. The highest and lowest yield per plot 46.43 kg/ha and 26.66 kg/ha was recorded from Ts and control treatment respectively. The maximum yield (77.39 tlha) was recorded from T5 treatment and the minimum yield (44.43 tTha) was recorded from the T 9 treatment. The highest nitrogen content (1.63%) in plant was recorded from 14 treatment and the lowest nitrogen content (0.82%) in plant was recorded from T 9 treatment. The highest phosphorus content (0.386%) in plant was recorded from I treatment and the lowest phosphorus content (0.124 1 /o) in plant was recorded from I g treatment. The highest nitrogen content (0.081 %) in soil was recorded from T treatment and the lowest Nitrogen content (0.050%) in soil was recorded from 19 treatment. The highest phosphorus content (25.67 ppm) in soil was recorded from T 4 treatment and the lowest phosphorus content (20.60 ppm) in soil was recorded from T 9 treatment. The highest sulphur content (14.45 ppm) in post harvest soil was recorded fromT5 treatment and T5 treatment and
