Monsoon Rice Planting in Nepal: Harvest Timing, Seed Selection & Fertilizer Guide

Finish Harvesting Spring (Chaite) Rice Safely

If you still have chaite rice standing when monsoon planting begins, don't rush the harvest. Cut only once the grain separates cleanly from the base of the panicle — cutting too early leaves grain unfilled, while waiting too long risks shattering and rot from early rains. Check the weather forecast before you commit to a harvest date.

Choosing Seed for the Main Season

Never save seed from a field that showed neck blast, blast, or kernel smut — these diseases carry straight into next season through the seed. Select only healthy, disease-free panicles, and make sure moisture content is under 12% before storage. Treating seed with a fungicide (2g per kg of seed) before storing dramatically cuts losses to rot. For the Pokhara valley and similar mid-hill areas, proven local varieties like improved Jethobudho, Ekle, Rato Anadi, Wayrni, Lal Anadi, and Kalo Patle remain reliable choices.

Regional Fertilizer Rates

Work six tonnes of organic manure per hectare into the soil during final land preparation before transplanting. Chemical fertilizer requirements vary by region and variety:

• Inner Tarai (Nawalpur): 55kg urea, 87kg DAP, 67kg MOP, 10kg zinc sulfate, 10kg borax per hectare — plus an additional 91kg urea split between tillering and pre-flowering stages.
• Hill regions: 46kg urea, 65kg DAP, 50kg MOP, 10kg zinc sulfate, 10kg borax per hectare — plus 74kg and 72kg urea at tillering and pre-flowering.
• Hybrid varieties (all regions): 66kg urea, 109kg DAP, 100kg MOP, 14kg zinc sulfate, 10kg borax per hectare — plus 109kg urea split between the two later stages.

Why Drought-Tolerant Varieties Matter This Year

This monsoon is forecast to bring below-average rainfall across the region. Prioritizing drought-tolerant rice varieties this season is a sensible hedge — they hold onto yield better if irrigation runs short partway through the growing cycle.

Improving Soil With Green Manure

On any plot sitting empty before transplanting, growing a quick green manure crop — dhaincha, sunn hemp, or mung bean — and turning it into the soil before you plant rice improves both nutrient availability and soil structure. It's a low-cost way to reduce how much chemical fertilizer you'll need down the line.
