EFFECT OF POTASSIUM LEVELS ON THE GROWTH, YIELD AND YIELD ATTRIBUTES OF LENTIL (Pages : 1 - 6)

A split experiment was conducted at the Agronomy Field Laboratory, University of Rajshahi to study the effects of potassium levels on the growth, yield and yield contributing characters of lentil. The experiment comprised of three varieties viz. BARImasur- 4, BARImasur-5 and BARImasur-6 and five potassium levels viz. 0, 15, 25, 35 and 45 Kg K ha-1 . The results revealed that among the three varieties, BARImasur-6 produced the highest seed yield (2.24 t ha-1 ) and BARImasur-4 produced the lowest seed yield (1.79 t ha-1 ). Grain and stover yield of all varieties were increased with the increase of potassium application up to 35 kg ha-1 . The highest grain yield (2.16 t ha-1 ) was found at 35 kg K ha-1 and the lowest grain yield (1.61 t ha-1 ) was exhibited from control potassium level and the highest stover yield (3.89 t ha-1 ) was also found in 35 kg K ha-1 and the lowest (3.32 t ha-1 ) was found in control potassium level. In case of interaction, the highest seed yield (2.58 t ha-1 ) was produced by BARImasur-6 with 35 kg K ha-1 . Therefore, fertilization of all the varieties with 35 kg K ha-1 appeared as the best rate of potassium in respect of grain and stover yield. It can be suggested that farmers may be used BARImasur-6 with 35 kg K ha-1 for better grain and stover production of lentil. Download
