Differential sensitivity of mineral elements to moisture stress in chickpea(Cicer arietinum)

Chandana Jain, Pratima Jain

Abstract :

Chemical analysis of chickpea varieties revealed differential sensitivity of mineral elements studied for moisture stress. Phosphorous, potassium, magnesium and sodium elements were increased while calcium, iron and zinc found to be decreased due to moisture stress. In the study average 7.26 % phosphorous found to be increased over non stress. Five verities recorded high (>10.0%) increase in phosphorous value. Increase in potassium concentration was average 4.27%. Six varieties recorded high (>6.0%) increase whereas rest eighteen varieties showed medium to low increase in potassium concentration. Magnesium recorded average 6.28 % increase over non stress.Six varieties recorded high increase ofmore than 10% in magnesium. Sodium concentration increased by average 0.28% over non stress content value. Moisture stress reduced content value of calcium by 9.92% in grains over non stress. More than 15% reduction in calcium was recorded in four varieties, rest of the twenty varieties recorded medium to low decrease in content. Iron content decreased by average 7.35% due to moisture stress environment. High decrease (>10.0%) in concentration of iron was observed in seven chickpea varieties whereas seven varieties showed low reduction (< 5.0%) in iron under moisture stress. Similarly zinc also decreased by average 7.65% under moisture stress in varieties.
