| Brief Description |
This is the Study 1 of the project "Varietal Improvement of Glutinous Corn, Seed Production and Maintenance of MMSU Glut 1".
Major activities include: - Crop establishment (land preparation, lay outing, planting, fertilizing, irrigating, putting of labels)
- Crop maintenance (irrigating, spraying, weeding, fertilizing, hilling-up)
- Gathering of data, harvesting, shelling, drying
- Data collation, analysis, encoding, interpretation
- Report writing
Seed Production of MMSU Glut 1
- Design. The experiment will be laid out in a randomized complete design with four replications. The size per plot will be 3m x 5m with four rows per entry.
- Land preparation. The land will be thoroughly prepared. Furrows will be constructed at 75 cm between rows.
- Treatments. Corn hybrids and OPVs entries are the treatments with 3-4 sets of studies per cropping season.
- Fertilization. The fertilizer rate to be used will be 120-60-60 kg N, P2O5, & K2O. One half of N and all P & K will be applied basal and the other half of N will be side dressed before hilling up at 21-25 days after planting (DAP).
- Planting & Thinning. Plant two seeds per hill spaced 20 cm apart between hills. Thinning will be done two weeks after emergence leaving one plant per hill.
- Weeding, cultivation. Weeding will be done as the need arises to control crop weed competition. Hilling up will be done as the plants are at knee high or 21-25 DAP.
- Control of insect pest. Insecticides will be sprayed during the growth stages of the crop to control insect pest following the manufacturer's dosage.
- Harvesting. Harvesting will be done for green corn at 19-24 days after silking while for grain corn will be harvested at physiological maturity at 45 days after silking.
- Data Gathering. The data to be gathered are the following: stand count, silking days, plant height, ear height, kernel rows, yield, moisture content, shelling percentage, ear weight, insect (borer) rating (30, 45, 60, 75 DAP), barren plants, percent filled and unfilled ears, disease rating (rust, etc). All data gathered will by analyzed by using RCBD ANOVA and LSD for treatment comparisons. The data gathered will be submitted to the NCT Coordinator.
For the Development of New Glutinous Corn Variety - Season 0 - 2010-2011 DS. Crossing of MMSU Glut 1 x Farmer's Variety. At maturity, harvested the superior plants/ears (as to color, size, etc). Shelled ears make it composite seeds and tag as S0 seeds.
- Season 1 - 2011 WS. The S0 seeds were planted and at maturity the superior plants were selected. The ears were shelled and tag as S1 seeds.
- Season 2 - 2011-2012 DS. The S1 seeds were planted and at maturity. The superior plants were selected and shelled and tag as S2 seeds.
- Season 3 - 2012 WS. The S2 seeds were planted and at maturity superior plants were selected, shelled and tag as S3 seeds.
- Season 4 - 2012-2013 DS. The S3 seeds were planted in replicated trials in campus and in farmer's field.
- MMSU Glut 2 seeds will be entered to the NCT for DS 2013-2014 trials.
- The plants were subjected to the protocol of NCT on corn.
