Response of Drip Irrigated Spring Maize to DifferentLevels of Salinity

摘要

The four treatments of drip irrigation with saline water of2000 mmho/cm (EC-2), 4000 mmho/cm (EC-4), 6000 mmho/cm (EC-6) and 8000 mmho/cm (EC-8) electrical conductivity were compared with drip irrigation by normal water, having electrical conductivityin the range of 600-700mmho/cm. Maximum plant height was recorded under normal irrigation water, which was statistically at par with EC-2 and EC-4 irrigation treatments. Significant differences in the number of grain per cob were observed and maximum number of grains per cob were recorded under EC-2 irrigation water. Significantly higher yields were recorded under EC-2 and EC-4 irrigation treatment as compared to higher saline water treatments of EC-6 and EC-8. No significant difference was observed inprotein content, carbohydrates and oil content of the grains under different treatments.
