Syngenta’s Agrisure NK8840 bested 14 other corn varieties entered in the Corn Derby conducted recently in San Felipe, Ilagan City, Isabela, by the Department of Agriculture – Cagayan Valley Research Center (DA-CVRC).
This Bt corn that is Glyphosate Tolerant yielded 12,823.23 kilos per hectare at a production cost of P3.43 per kilo. Sold at dry weight basis at P11.20 per kilo, gross income was computed at P143,620.18, giving a net income of P99,574.18 per hectare. Cost of production was P44,046 per hectare.
The Corn Derby is a project of the Department of Agriculture in which different varieties from the seed companies are planted in one location to compete with each other. The results will give the farmers valuable information upon which to base their decision in choosing the varieties they plant.
Agrisure NK8840 is recognized for its big cob, big kernels, proven consistent high yield over the years. Other desirable characteristics include low placement of the ears, hence easy to harvest; and it has a high shelling recovery of 78 to 80 percent.
Two other Syngenta varieties bested the 12 other varieties entered by the other seed companies that included Monsanto, Bioseed, Pioneer, Cornworld Evogene and Asian Hybrid. Syngenta’s NK6414 yielded 12,655.58 kilos per hectare while NK6410 yielded 12,580.23 kilos per hectare.
In achieving Syngena’s high yields, the production team followed the following nutrient management schedule. Just before planting the seeds (0 DAP), 100 kilos of organic fertilizer and 37.5 kilos of complete fertilizer were applied separately on 2,500 sq.m. plot. That’s the basal application. First side dressing was done 15 days after planting (DAP) consisting of a mixture of 37.5 kilos of 14-14-14 and 25 kilos urea per 2,500 sq.m. plot. Second side dressing was done at 25 DAP consisting of a mixture of 25 kilos 14-14-14, 12.5 kilos urea and 12.5 kilos 0-0-60 per c,500 sq.m.
For weed control, the plots were sprayed with Atrazine and Herbadox on the day of planting. Twenty five days after planting Alika, an insecticide, was sprayed on the plants. Second Alika application was done at 45 DAP. Armure, a fungicide, was applied 55 days after planting.
The the three Syngenta entries were planted on June 8, 2017 and harvested on September 26, 2017 (110 days DAP).
The 2nd placer, NK6414 has its own strengths and weaknesses. Its strengths: Suitable for high density planting; responds to high inputs; easy to harvest because the ears are low; good for both wet and dry season.
The 3rd placer, NK410, on the other hand, shows high consistent high yield in both wet and dry seasons. It has good standability and semi-drought tolerance; suitable for normal to medium population density.
