Adaptability of Maize to High Soil Water Conditions1

Abstract

Abstract

Maize (Zea mays L.) plants were grown in furrows and ridges in a lowlying sandy clay loam soil under high soil-water conditions. Root porosities of 44-day-old plants were studied. The investigation was undertaken to determine varieties that could adjust to such environment through internal aeration.

Varietal differences were found in the percentage of air space of roots. Plants grown in furrows had higher root porosities than those grown in ridges. Six varieties studied were ‘Kissan,’ ‘Deccan,’ ‘Jawahar,’ ‘Ganga 5,’ ‘Vikram,’ and ‘Sona.’ The first two may adjust better to excess soil water due to greater internal aeration resulting from increased root porosities.
