The effect of N, P and NP upon grain and stalk production of nonnodulated soybeans cv. Halesoy 71, was evaluated. Test were carried out during the 1974-1975 season in the Experimental Field of the College of Agrarian Sciences in Rosario, located in Zavalla, Santa Fe. The soil (in this locality) is a...

description The effect of N, P and NP upon grain and stalk production of nonnodulated soybeans cv. Halesoy 71, was evaluated. Test were carried out during the 1974-1975 season in the Experimental Field of the College of Agrarian Sciences in Rosario, located in Zavalla, Santa Fe. The soil (in this locality) is a Brunizem, class II according to its utilization capacity. The experimental design consisted of randomized blocks with four replication. The P was applied in furrows in the form of Tribasic Calcium Phosphate at sowing time, while N (urea) was placed at the plant base at the time of flower sprouting. The response of non-nodulated soybeans to N application was lineal for grain production, showing a 21% increase at the highest rate utilised (125 kg/N/ha). This increment was significant with respect to the non-nodulated control plant. The production of unfertilized nodulate soybeans was 33% greated than that of the control plants, which was considered to be highly significant. Increased P rate reduced grain production as low as 10,5% for the 100 kg/P/ha rate. The control treatment could only be exceeded in 4% with 150 kg/P/ha, with was the highest rate tried. These difference were not significant All N and P combination increased grain production. The maximum dose of 100 kg of N and 100 kgof P brought about an increment of 18% which was a statistically significant difference. Stalk yield was lower in the fertilizer plots, regardless of the fertilizer used and of the dosis applied. The relation stalk weight/grain weight, decreased with higher fertilizer doses and its was due, in the case of the fertilization with N and NP, to decrease in stalk production and increment in grain yield, and for P, to a higher decrease in the production of stalk than that of grain.
