INFLUENCE OF NITROGEN AND SULPHUR ON GROWTH AND YIELD OF CARROT

Abstract

The present investigation entit led “Influence of nitrogen and sulphur on growth and yield of carrot” was conducted from January, 2019 to February, 2020 at the horticulture Farm of Sher-e- Bangla Agricultural University, Dhaka, Bangladesh. The experiment comprised of two factors; viz. Factor A: Four levels of nitrogen fertilizer (0 kg N/ha, 40 kg N/ha, 80 kg N/ha and 120 kg N/ha) and Factor B: Three levels of sulphur (0 kg S/ha, 5 kg S/ha and 10 kg S/ha) of carrot. The experiment was laid out in a Randomized Complete Block Design with three replications. In case of nitrogen fertilizer application, the highest plant height, number of leaves, length of leaves, fresh weight of plant, dry weight of plant, length of root, diameter of root, dry weight of root and yield were recorded and lowest percent of cracked roots per plot and lowest percent of rotten roots per plot were recorded of carrot in case of application of nitrogen @ 120 kg N/ha. In case of different levels of sulphur, the highest plant height, number of leaves, length of leaves, fresh weight of plant, dry weight of plant, length of root, diameter of root, dry weight of root and yield were recorded and lowest percent of cracked roots per plot and lowest percent of rotten roots per plot were recorded of carrot in case of application of sulphur @ 10 kg S/ha. Again, the highest plant height, number of leaves, length of leaves, fresh weight of plant, dry weight of plant, length of root, diameter of root, dry weight of root and yield (22.21 ton/ha) were recorded and lowest percent of cracked roots per plot and lowest percent of rotten roots per plot were recorded of carrot in case of combined effect of nitrogen @ 120 kg N/ha and sulphur @ 10 kg S/ha applying in the carrot field.
