9. Sowing details
Date of sowing : 10/07/19
Seed treatment : Soaking of seeds in water for 24 hours
Method of sowing : Line sowing
Seed rate : 75 kg/ha
Seed Requirement :
10,000m2 land required 75kg seed
20m2 land required (75×20/10,000) =0.15kg =150gm
Depth of sowing : 5 cm
Spacing : Row to row 20 cm
Land preparation
I. Tillage operation was done with the help of phawrah and trench hoe
for increasing porosity of the soil.
II. Levelling was done with the help of leveller for maintaining proper
slope of the plot.
Implement used: Phawrah, Trench hoe, Garden rake, Leveller
Sowing

10. Nutrient management

14. Hoeing at 15 DAS
Hand weeding
1) Weed Management:
2) Water Management:
•Weed Management Done By: Hand Weeding [15 DAS, 30
DAS, 45DAS]
•Critical stage for crop weed competition: 30-45 DAS
Here rice is grown as a kharif crop based on the natural
rainfall.
Water is applied by flooding method of irrigation as per
requirement.
Tillering to flowering is the most critical stage of irrigation.
3) Hoeing:
•Hoeing is done before fertilizer application for proper
incorporation of fertilizer.
•Besides this hoeing is done to reduce crop weed competition
.

15. Diseases of Rice
Name of the
disease
Causal Organism/
Cause
Symptom Control Measure
1. Blast Pyricularia oryzae Eye shaped spots
with grey or brown
margin appear on
the leaf.
•Seed treatment:
Thiram @2.5g/kg
of seed.
•Spray: Mancozeb
@0.3% on crop.
2. Bacterial leaf
blight
Xanthomonas
oryzae
Blightening starts
from tip of the leaf
to bottom.
Seed treatment:
Streptocycline
@0.02%
3. Brown leaf spot Helminthosporium
oryzae
Cylindrical or oval
to circular brown
spot appears on
leaf
Spray: Mancozeb
@0.2% on crop.

17. Maturity Index
◦ About 80% panicles have about 80%
of ripened spikelets.
◦ Upper portion of spikelets is of straw
coloured.
◦ The grains contains 20% of moisture.
◦ Harvesting dates: 29.10.2019(approx)

18. Yield Parameter

No. of chaffy
242 26.55 25.5 98 15
Estimated yield
Test weight= 26.55 g
No. of panicle per square meter= 242
Estimated yield per m2= (No. of panicle per m2 × No. of filled grains per panicle × Test
weight)/1000= (242 × 98 × 26.55)/1000 =629.65 g/m2
Yield of 1 hectare =629.65 ×10000 gm/ha =62.96 q/ha ~63q/ha
Yield of 20m2 = (63 × 20)/10000 q =12.6 kg
