25No-till Tobacco Production
- Soil Conservation
- Moisture Conservation
- Reduced Field Preparation
- Allows timely field operations
- Cleaner cured leaf
26Transplanter Modification
- No-till Colter
- Cuts residue
- Provides narrow tilledzone
- Subsoil shank
- Provides loose soil under root ball
- Pulls unit into soil
- Press wheels
- Close and firm soil around roots
27Recommendations to Growers
- Learn as much as possible
- Extension sources
- Magazine articles
- Other growers
- Start slow, and learn fast !!
- Greater attention to detail
- Plan ahead
- Select sites carefully
- Past crop history
- Weed pressure
- Soil type

30Fertility TrialJackson Co. Ron Madden Farm
Broadcast Sidedress
Number lbs of product, AN Ammonium Nitrate,
CN Calcium Nitrate, SN Sodium Nitrate
31Nitrogen Fertilization Sources
32Attributes of Nitrate Nitrogen
- Prevent acid soils and low pH
- Reduce chance of Nitrate loading of plants
- Reduces green cure
- Reduces fat stems
- Which can freeze and bleed onto leaf
- Which can lead to high moisture reading at market
33High chloride in tobacco
- Sources
- Muriate containing fertilizers
- Chicken Liter
- Poor cured leaf color
- dingy, muddy, variegated
- Imparts unpleasant flavor and aroma to smoke
- Reduces burn rate
- Cause cured leaf to hold moisture
- moldy stems / fat stems
- high case can lead to rot during storage
- nitrosamines ??
34Tomato Spotted Wilt
- Incidence is increasing
- Spread by Thrips
- Field infection
- Few plants
- Strong edge effect
- Transplant infection
- Many plants
- Entire field

- Strip at appropriate moisture
- No Fat Stems
- Avoid over compaction in bales
- Tighter bales will cause higher moisture reading
