Characteristics of good quality seed

● no contamination or admixture in the seed● high germination capacity● free from disease● high germination capacity● free from weeds, soil particles, sand and stones● no broken seeds● true-to-type genetic purity

Cultivation Guide for Hybrid Rice

Varieties:

● Bangladesh Rice Research Institute developed 4 hybrid rice varieties namely, BRRI hybriddhan,1, 2, 3, for Boro and BRRI hybriddhan4 for T.aman. ● hybrid rice variety seeds are available both imported and local production. ● To collect seeds a farmer have to consider reliability of the company and the desired grain quality which are seen from outside of the packet.

Soil Testing:

Have your land tested by the Soil Resources Development Institute or Department of Agriculture Extension as liaison office to know its fertilization and acidity level. In this way, you will be informed about the right amount of fertilizer to be used and if your soil still needs lime.


Potential

Land Preparation

Prepare the land two to three weeks before transplanting to ensure the fast and ideal growth of the Pioneer Hybrid Rice to be planted. This will hinder the early growth of weeds and help in proper management of fertilizer and farm irrigation.


Potential

Plowing. Plow the land once with a medium depth, preferably 10-15 centimeters. However, it may not be necessary if there is enough soft soil for transplantation of seedlings.

Leveling: Level the land with the use of a plowshare or a hand tractor.

Dike reconstruction: Clean and fix the embankments to close up any holes that may serve as rats' nest or waterway that will lead to water spillage.


Potential

Seed and Seedbed Preparation

Choosing the seedbed: Choose an area of the farmland which is far from the shade.

Preparing the seedbed: Make a 300-400 sqm seedbed for a 15-20 kg of seeds, good for one hectare of land. A seedbed is considered medium if it is one meter wide; its length depends on the cut of the paddy. Put organic fertilizer with the quantity of 1 kg per sqm to making the seed grow healthy and pulling out easier to lessen damage to the roots.


Potential

Soak the seeds in clean water for 24 hours. Regularly change the water every 6 hours in order to prevent the seeds from spoiling. Cover it and keep it airtight for 24-36 hours. Make sure that you keep the seeds damp.

Preparing the seed for seedbed

Germinated seeds


Potential

Irrigate the seedbed after 2-3 days with a depth of 2-3 cm. Keep the seedbed well irrigated until the day when you will pull the seedlings out. On the tenth day, strew 20-40g of urea per 1 sqm or 8-16 kg per 400 sqm. It is important that the seedbed be guarded from damage brought upon by birds and lack of irrigation.

Seeding on bed: Grasp a handful (50 grams per 1 sqm) of the seedlings and spread them to the damp seedbed.

Nursing the seedlings


Potential

A seedling that is 18-21 days old can already be transplanted. Sow 1-2 seedlings per hill with a distance of 20 x 15 cm during dry season and 20 x 20 cm during wet season. Do not trim the leaves of the rice because the wound may let in bacteria that will cause plant diseases. Sow seeds to the missing hills within a week.

Fertilizer Application

If a soil analysis was not conducted on your land, please refer to the following recommendations:

Basal: Strew basal fertilizer on the last harrowing session so that it will be mixed well with the soil.

Top-dress: Spread the fertilizer during the tillering, vegetative and reproductive stages.For the right kind and amount of fertilizer to be used, please refer to the table below:


Potential

Basal (1 day before transplanting) TSP 500 /grams/decimalMOP 300 /grams/decimalZinc Sulphate 40/grams/decimal

Gypsum 250/grams/decimal

Early Tillering (7-10 after transplanting) Urea 300/grams/decimal

Late Tillering (21-25after transplanting) Urea 500-600/grams/decimal

Panicle Initiation (7 days before) Urea+ As on crop condition

Panicle Initiation (7 days before) MOP 150/grams/decimal

Recommendation depends on soil fertility and yield potential of the variety the thumb rule for production of rice 6ton/ha apply 108kg N, 18kg P, 120kg K and 11S/ha.

Potential Irrigation and water ManagementDuring the early vegetation stage, it is fit that the water depth is at 2-3 cm. At maximum tillering stage when the desired no of tillers are produced dry the land up to small creaks appeared. This will help in the growth of roots and prevent unwanted tillering. Raise the water level to 5-7 cm during the reproductive stage and keep it at that level until the grains are milky. The rice paddy may be drained 1-2 weeks before harvest.* Do not select a plot where water stands all time and out of control of irrigation water particularly near the irrigation pump or plots at lower areas. Due to higher seed cost 1-2 seedlings are used/hill so for better tillering water level in the fields need to be very low at that stage.


Potential

Controlling the weeds:

Proper management of the irrigation is the most effective way of controlling weeds. Exterminate the weeds in the rice paddy on the first 40 days after transplanting. Use bare hands, rotary weeder or any recommended herbicide in controlling the weeds.


PotentialManaging the pests

Time your planting with the other farmers in your community. In this way, you will be able to prevent insects and plant diseases from attacking your farm. It is also advised that rice farmers practice the principles of the Integrated Pest Management. This includes combinations of various ways to eliminate or control pests without damaging the possible yield and earnings of the farmer.Pest that attack leaves: Since rice have the ability to replace damaged leaves within the first 40 days after transplanting, it is expected that pesticides will not be needed anymore.


Potential

Stem borer: Use a systemic pesticide on the base of the rice plant when there are a lot of white heads and dead heart in the plant. Moths or egg cluster 2-3/meter square up to 40 days after planting or 10% dead heart/square meter upto 40days after transplanting or 5% dead heart upto 60 days after transplanting. Rats: Use rat poison if there are already too many of them in your farm. Keep the rat traps up to two weeks before harvest time. Keep the embankments clean so that rats will not inhabit them.

Managing the pests cont.


Potential

Disease:

In pest management, avoid excessive usage of nitrogen, a high population of weeds, asynchronous planting and continuous irrigation. You may use recommended pesticides in eliminating diseases in your rice fields.For Blast apply Hinosun 800ML/ha and for Sheath blight spray 500ML/ha Folikul

Sheath Blight

Potential

Harvesting:Start harvesting the rice when 80-85% of the grains are already ripe. Thresh the harvested rice grains right away. Introduction of combine harvester started in Bangladesh due to scarcity of farm labor. Combine
