INFLUENCE OF SEED SIZE ON SOY PHYSIOLOGICAL QUALITY

Abstract

THE DEMAND FOR SEEDS OF GOOD PHYSICAL, PHYSIOLOGICAL AND SANITARY QUALITY HAS INCREASED, AND SEED PRODUCERS HAVE BEEN PRACTICING THE CLASSIFICATION OF SOYBEAN SEEDS BY SIZE AFTER THE CLEANING PROCESS. DESPITE THE ADOPTION OF THE PRODUCERS OF THE CLASSIFICATION BY SIZE, THERE IS STILL CONTROVERSY REGARDING THE EFFECT OF THE SIZE OF SOYBEAN PERFORMANCE CULTURE. THE PRESENT WORK AIMS TO VERIFY THE INFLUENCE OF SEED SIZE ON THE PHYSIOLOGICAL QUALITY OF SOYBEAN. FOR THIS, A SOYBEAN CULTIVAR, BMX, WAS USED. IPRO BONUS, CLASSIFIED IN THREE SIZES: 5 MM; 6 MM AND 7 MM. AND CARRIED OUT GERMINATION TESTS ON SITE AND LABORATORY TEST AND FORCE THROUGH: DRY MASS OF SEEDLINGS, SEEDLING LENGTH. IT WAS FOUND THAT SEEDS OF 6 MM SIEVE HAS HIGHER GERMINATION RATES IN TESTS ON THE FIELD SITE. THE CLASSIFICATION OF SEEDS HAS DIRECT INFLUENCE ON THE RATE OF GERMINATION AND SEED VIGOR AND THE SEED STORAGE
