Response of Four Soybeans Varieties to Soil Moisture Levels

Abstract

The present investigation aimed to study the responses of four soybeans varieties S,Pi,G and Lee to soil moisture levels ( 100,80,70 and 50% from field capacity). Result showed that Pi variety was superior in osmotic potentials by 30 and 38% than S and Lee varieties and superior in its contents of potassium by 51, 17 and 37% on the other varieties respectively. The Varity lee was superior in the dry weight of plants, number of pods/plant and seeds yield/plant by 60, 71 and 60% than the other varieties respectively. S variety gave highest evapotranspiration (ET) 1000mm, on the other hand the variety Pi gave the lowest ET 777mm. The soil moisture level 100% gave higher dry weight of roots, dry weight of plants, number of pods/plant, and seeds yield/plants by 73,86,89 and 99% than other soil moisture level respectively. Highest ET 1200mm obtained by soil moisture level 100%, where as the lowest ET 581mm gave by soil moisture level 50%.
