Effect of Exachangeable Sodium Percentage on Growth, Yield and Chemical Composition of Onion and Garlic Singh S.B., Abrol L.P. Central Soil Salinity Research Institute, Karnal, Haryana, 132001 Abstract In a field experiment at the CSSRI, Karnal (Haryana), the effect of exchangeable sodium percentage(ESP) of the soil on growth, yield and chemical composition of onion (Allium cepa L.) and garlic (Allium sativum L.) was studied. There was continuous decrease in dry matter production at I (30 days after tranplanting and sowing of onion and garlic, respectively) and U (at harvesting) stages of growth and in diameter, weight and yield of bulb of the two test crops with rise in ESP. A significant negative correlation between ESP and bulb yield was observed. In both the crops the content of Na increased and that of Ca decreased with higher ESP levels. A fall in K content was noted in onion only. Onion was found to be more sensitive to sodic condition than garlic. Top Keywords Exchangeable sodium percentage, chemical composition, plant growth, bulb yield, onion, garlic. Top | |
