EFFECT OF ZINC AND MOLYBDENUM ON THE YIELD AND QUALITY OF SARI TOMATO-S (LALIMA) (Lycopersicon esculentum Mill.) AND THE POST HARVEST SOIL

Abstract

The experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University thrm, during the period from December 2008 to March 2009 to find out the effect of zinc and molybdenum on the yield and quality of tomato. The experiment consisted of two factors as A (Four levels of Sc): Zn 0: 0 kg Zn/ha. Zn 3 : 3 kg Zn/ha, Zn 6 : 6 kg Zn/ha, Zn 9 : 9 kg Zn/ha, and B (Four levels of Molybdenum): M 0 : 0kg Mo/ha, Mo 05 : 0.5 kg Mo/ha. Mo 1•0 : 1.0 kg Mo/ha, Mo 15: 1.5 kg Mo/ha. In case of zinc treatment, plant height, number of leaf, number of flower cluster, number of flower, number of fruit, single fruit weight, vitamin-C content and yield increased significantly with increasing Zn level up to 6 kg Zn/ha 9). The maximum plant height (63.63), fruit number (44.17), vitamin-C content (Zn6 ) whereas vitamin-A content increased significantly up to 9 kg Zn/ha (Zn (17.52 mg/ I OOg) and yield (44.26 tlha) were recorded from Zn 6 treatment. The maximum vitamin-A content with Zn 9 was (6444.0 .tg/100g). The maximum zinc (361.50 ppm) uptake was recorded from Zn 9 treatment and the minimum zinc (190.3 ppm) uptake was recorded from Zn 0 treatment. In case of molybdenum treatment, plant height, number of leaf, number of flower cluster, number of flower, number of fruit, single fruit weight, vitamin content and yield increased significantly with increasing Mo level upto 1.0 kg Mo/ha (Mo 1 .0 ) where as vitamin-A content increased significantly up to 1.5 kg Mo/ha (Mo 15). The maximum plant height (62.70 cm), fruit number (42.49), vitamin-C content (16.24 mg/bOg) and yield (41.46 tlha) were recorded from Mo 10 treatment. The maximum vitamin-A content with M 1.5 was (6047.0 j.tg/lOOg). The combined effect of Zn and Mo showed that the combination ofZn 6M1•0 as 6 kg Zn/ha+1 .0 kg Mo/ha gave the highest yield (4706 tlha) and vitamin-C content (18.60 mg/bOg) while the highest vitamin-A content was obtained from the combination Zn 6Mo 5.
