Land Preparation
This is a pre-requisite for good crop husbandry. Plowing the fields during summer season helps controlling weeds. Prepare the field by ploughing and cross ploughing early in the season followed so that the field is ready for sowing before the regular onset of monsoon. Allow the weed seeds to germinate. Adopt shallow harrowing to kill the weeds that emerge. Later on, level the field before sowing.

Time of Sowing
This is a critical point to achieve the success in upland rice. The sowing of crops should be accomplished within second fornight of May with the regular onset of the monsoon. Timely sowing of rice helps for optimum growth of succeeding rabi crops.

Seed Rate and Seeding Depth
Use of row marker is very useful for proper spacing (20 cm) and reducing seed rate. For broadcasting a higher seed rate (25-30 kg ha-1) is required. Seeding depth plays key role for good germination. Depth should not be kept more than 3 cm for desired level of crop stand. Placement of seeds below 3 cm adversely affects dynamics of seed emergence because of rapid drying of the upper layer soil moisture

Nutrient Management
Nutritional requirement should be met on the basis of soil analysis of the crop field. In absence of soil analysis, application of 60-40-40 kg N ha-1, 60 kg P2O5ha-1and 40 kg K2O ha-1is recommended. 50% dose of nitrogen and 100% dose of phosphorus and potassium should be applied at the time of sowing (basal). The remaining 50% dose of nitrogen should be given in two splits vis. 30 and 60 days after sowing (DAS). If available it is also recommended to apply 5 ton FYM/ha during land preparation (20 days before sowing).Apply manure and fertilizers in the following split doses
Nutrient | Duration of Variety | Fertilizer dose (kg/ha)
|
|||
---|---|---|---|---|---|
N (60kg/ha) | Urea |
|
|||
P2O5 (40 kg/ha) | Single super phosphate(SSP) |
|
|||
K2O (40 kg/ha) | Muriate of potash (MOP) |

Gap Filling
Re-sowing of seed should be done in rice lines within 7-10 after sowing where the seeds failed to emerge or crop establishment is very poor.

Weeding Management
• Only use good clean seed (free of weed seeds).
• Select varieties that are more competitive and smothering efficiency.
• Direct seed in rows to facilitate hand or mechanical weeding.

Harvesting and Threshing
Harvest the crop when 5-10% of the grains at the bottom of the panicle are still to dry but the rest of the grains on the panicle are fully matured.
Rice crop is being harvested by simple hand tools like sickle 15-25 cm above ground level,the harvest is put together in bundles to improve handling and then dried in the field.
Threshing is the process of separating the grain from the straw. It can be either done by hand using a paddy thresher or mechanized by using a machine.

Drying of Rice Grain
Gradual drying of paddy should be done in sunlight to bring the moisture level to less than 12-13% for better milling and storage of the produce.
Store paddy in proper storage structures after adequate drying.
Use of locally available organic insect repellants like neem leaf etc. so as to prevent damage from insect and rats are also suggested.
