EFFECT OF DIFFERENT POTASH LEVELS ON THE GROWTH, YIELD AND PROTEIN CONTENTS OF CHICKPEA (CICER ARIETINUM L.)

摘要

A field experiment was carried out to study the effect of varying levels of potash (0, 25, 50, 75, 100, 125 and 150 kg B_2O ha~(-1)) on growth and yield of chickpea (Cicer arietinum L.) cultivar CM-2000 at the Agronomic Research Area, University of Agriculture, Faisalabad, during the winter season 2003-2004. The growth and yield components were significantly increased by different potash levels. However, the differences between control and 25 kg K_2O ha~(-1) were nonsignificant for the number of podsper plant and 1000-seed weight. The application of 25 kg K_2O ha~(-1) could .not increase the seed and biological yield significantly thereafter, seed yield increased gradually with the increase in potash levels and the maximum seed yield (2341 kg ha~(-1)) was obtained with 150 kg K_2O ha~(-1). The seed protein contents also increased gradually with an increase in-potash level and maximum protein contents (23.87) were recorded with application of 150 kg K_2O ha~(-1). The highest potash level resultedin maximum net benefit as well.
