Nursery Management

NURSERY MANAGEMENT

The main importance of nursery management is to secure a uniform plant population of rice plant that can produce more vigorous plant and high yields

Types of Rice Nursery:

There are mainly three different type of rice nursery

I. Dry nursery

II. Wet nursery

Land system pattern

Land system pattern:

  • This system requires ploughing to begin in the center of the field and works out to the edges.
  • It requires some measurement of the field to establish the center point and if done correctly leaves a level field with drainage channels on the edges.
  • This system can be used with all types of ploughs.
  • In very large fields, a number of lands may be ploughed

Up and back or headland pattern

Up and back or headland pattern

  • The field is ploughed in runs parallel to each other.
  • It starts at one boundary of the field and ends at the opposite with turns being made on the headlands.
  • This system can only be used for tined implements, rotovators, harrows and reversible ploughs.
  • It is usually the most field efficient system and if equipment is correctly set up and operated should not leave furrows in the field

Types of Tillage

Types of Tillage: Tillage is divided into two classes:

  • Primary tillage,
  • Secondary tillage

I)Primary Tillage:

It constitutes the initial major soil working operation. It is normally designed to reduce soil strength, cover plant materials and rearrange aggregates. The operations performed to open up any cultivable land with a view to prepare a seed bed for growing crops is known as primary tillage.

Primary tillage Implements: It may be tractor drawn or animal drawn implements.

Tillage Patterns

Tillage Patterns

1. An optimal tillage pattern reduces the time spent in non-productive work.

2. One of the most important objectives of a tillage pattern is to minimize the number of turns and maximize the length of the tillage runs.

3. There are several patterns that can be used when tilling a field. These are

  • Circuitous pattern
  • Up and back or headland pattern
  • Land system pattern

Tillage

Tillage

It is a mechanical manipulation of soil to provide favorable condition for crop production. Soil tillage consists of breaking the compact surface of earth to a certain depth and to loosen the soil mass, so as to enable the roots of the crops to penetrate and spread into the soil. These objectives are include:

LAND PREPARATION

LAND PREPARATION:

Land leveling is expected to bring permanent improvement in the value of land. Leveling work is carried out to modify the existing contours of land so as to achieve certain objectives desired for efficient agricultural production system. These objectives are includes:

(i) efficient application of irrigation water,

(ii) improved surface drainage,

(iii) minimum soil erosion

Harvesting and Threshing

Harvesting and Threshing

1. The crop is harvested close to the ground when about 90 per cent of the grains in the panicle are grey in colour ( Straw colour).

2. Delayed harvesting causes considerable loss by shattering of grains resulting in considerable loss in yield and increased percentage of broken rice in hulling and due to damage by rats and birds.

Integrated Nutrient Management

Integrated Nutrient Management

1. Integrated nutrient management approach is required to ensure higher yield. The principle is that most of the fertilizer should be applied up to tillering stage (70–80%), while a small portion should be applied at later stages.

2. An application of 10 t/ha of FYM in the field before pudding is advisable. The application of organic manure at 10–15 t/ha (fresh weight) before ploughing or puddling in addition to inorganic N, P & K is useful.

Water management

Water management

1. For effective water management, field should be levelled.

2. A water level of up to 1–2 cm should be maintained from the time of transplanting till establishment of seedlings (10 DAT) and it should be increased and maintained up to 2–3 cm for the promotion of tillering.

Transplanting

Transplanting:

1. This method should be used in the regions having rainfall more than 1000mm. This method is extensively in the Konkan and Vidarbha regions of Maharashtra.

2. Seed rate should be 35-40 kg /ha. In case of rice hybrids 20 kg seeds are sufficient for one hectare. The nursery of 1000 sq.m. is sufficient for transplanting of one hectare.

Direct seeding of rice

Direct seeding of Rice

1. This method should be used in the regions having rainfall less than 1000 mm.

2. This method is followed in non- traditional areas of Maharashtra like Marathwada, Western Maharashtra.

3. In this method, 80-100 kg seeds require for one hectare.

4. Seed treatment of Thiram @ 2 g/kg of seeds, 24 hours before sowing is necessary to prevent seed born and soil born diseases.

Land preparation for Central Telangana Zone

• Ploughing followed by puddling ten days before transplanting and by following perfect leveling.

• Normally 33 hills/ sq.mt. (20 x 15 cm) is optimum plant density for heavy and fertile soils.

• In light and sub marginal soils a spacing 15 x 15 cm (44 hills/sq.mt.) may be adopted.

• In delayed conditions, adopt 44 hills/sq.mt.

• In order to reduce the weed growth and for better water management, good leveling of the main field has to be followed.

• 25 – 30 days aged seedlings should be used for planting. Planting should be completed before 3rd week of July.

Characteristics of good seed

Characteristics of good seed

1. Seed must be true to its type i.e. genetically pure, free from admixtures and should belong to the proper variety or strain of the crop and their duration should be according to agroclimate and cropping system of the locality.

2. Seed should be pure, viable, vigorous and have high yielding potential.

3. Seed should be free from seed borne diseases and pest infection.

4. Seed should be clean; free from weed seeds or any inert materials.

5. Seed should be in whole and not broken or damaged.

Seed quality

Seed quality

Following are the advantages of using good quality seeds,

1. Uniform germination thus avoiding replanting, gap filling.

2. Vigorous seedling growth, which reduces weed and disease, damages.

3. Uniform growth stages, maturity and products.

4. Maintain good quality under storage conditions.

5. Reduced cost of cleaning, standardization and disinfections. 6. Reduced cost.

Dapog method of Nursery

Dapog method of Nursery

Dapog method of raising nursery consists of growing seedlings on a concret floor or a raised soil bed covered with polyethelene sheets. The method is used especially in places where supply of water in the seed-bed is dependable.

1. Seed rate: 25-35 kg/ha seed

Wet Nursery

Wet Nursery

1. Seed rate: 50-60 kg/ha for coarse variety, 35- 40 kg/ha for fine variety and 20 kg/ha for hybrids.

2. Seed treatment: Dry seed treatment: Seeds are treated with fungicide like Bavistin or Thiram @ 2 g/kg of seeds, 24 hours before sowing and the seeds are treated with Azospirillum at 600g per ha of seeds.
