Agricultural Production in Haryana

1. A remarkable increase in food grains production is visible in Haryana since inception of the State.

2. Production of total food grains in the State is likely to be 155.28 lakh tonnes in 2009-10.

3. The Wheat and Paddy crops have played a major role in pushing up the agricultural production.

4. The production of Rice is likely to be 36.25 lakh tonnes in 2009.

Average yield  of  Rice:

 The average yield per hectare of Rice during 2009-10 in Haryana is estimated at 3008 Kgs. per hectare.

Harvesting of transplanted hybrid rice

1.Taking the average duration of the crop as an indication, drain the water from the field 7 to 10 days before the expected harvest date as draining hastens maturity and improves harvesting conditions.

2. When 80% of the panicles turn straw colour, the crop is ready for harvest. Even at this stage, the leaves of some of the varieties may remain green.

3. Confirm maturity by selecting the most mature tiller and dehusk a few grains. If the rice is clear and firm, it is in hard dough stage.

Water management in transplanted hybrid rice

1. Puddling and leveling minimizes the water requirement.

2. Plough with tractor drawn cage wheel to reduce percolation losses and to save water requirement up to 20%.

3. Maintain 2.5cm of water over the puddle and allow the green manure to decompose for a minimum of 7 days in the case of less fibrous plants like sunnhemp and 15 days for more fibrous green manure plants like Kolinchi (Tephrosia purpurea).

Weed management in transplanted hybrid rice

1. Use of rotary weeder from 15 DAT at 10 days interval. It saves labour for weeding, aerates the soil and root zone, prolongs the root activity, and improves the grain filling though efficient translocation and ultimately the grain yield.

2. Cultural practices like dual cropping of rice-azolla, and rice-green manure (described in wet seeded rice section 2.5 & 2.6 of this chapter) reduces the weed infestation to a greater extent.

3. Summer ploughing and cultivation of irrigated dry crops during post-rainy periods reduces the weed infestation.

Transplanted hybrid rice

Seed rate - 20 kg per hectare

Nursery:

1. Basal application of DAP at 2 kg/cent of nursery area. Sparse sowing of seeds at one kg/cent of nursery area will give robust seedlings with 1-2 tillers per seedling at the time of planting.

2. If the soil is heavy, apply 4 kg gypsum/cent of nursery area, 10 days before pulling of seedlings. Age of seedling -20 to 25 days.

3. Spacing (cm)-20 x 10 (50 hills/m2) or 25 x 10 (40 hills/m2) according to soil fertility Seedlings/ hill-One (along with tillers if already produced) , Fertilizer-175:60:60 kg N, P2O5 and K2O/ha.

Harvesting for transplanted puddled lowland rice

1. Taking the average duration of the crop as an indication, drain the water from the field 7 to 10 days before the expected harvest date as draining hastens maturity and improves harvesting conditions.

2. When 80% of the panicles turn straw colour, the crop is ready for harvest. Even at this stage, the leaves of some of the varieties may remain green.

Precautions for irrigation for transplanted puddled lowland rice

1. The field plot can be 25 to 50 cents depending on the source of irrigation.

2. Field to field irrigation should be avoided. Field should be irrigated individually from a channel.

3. Small bund may be formed parallel to the main bund of the field at a distance of 30 to 45cm within the field to avoid leakages of water through main bund crevices.

4. To minimize percolation loss, the depth of stagnated water should be 5cm or less.

5. In water logged condition, form open drains, about 60cm in depth and 45cm width across the field.

Neem treated urea and coal-tar treated urea for transplanted puddled lowland rice

1. Blend the urea with crushed neem seed or neem cake 20% by weight. Powder neem cake to pass through 2mm sieve before mixing with urea. Keep it overnight before use (or) urea can be mixed with gypsum in 1:3 ratios, or urea can be mixed with gypsum and neem cake at 5:4:1 ratio to increase the nitrogen use efficiency. For treating 100 kg urea, take one kg coal-tar and 1.5 litres of kerosene. Melt coal-tar over a low flame and dissolve it in kerosene. Mix urea with the solution thoroughly in a plastic container, using a stick. Allow it to dry in shade on a polythene sheet.

Nutrient deficiency / toxicity symptoms for transplanted puddled lowland rice

1. Nitrogen deficiency : Plants become stunted and yellow in appearance first on lower leaves. In case of severe deficiency the leaves will turn brown and die. Deficiency symptoms first appear at the leaf-tip and progress along the midrib until the entire leaf is dead.

2. Potassium deficiency : Bluish green leaves - when young, older leaves irregular. Chlorotic and necrotic areas - grain formation is poor - weakening of the straw which results in lodging.

Application of P fertilizer for transplanted puddled lowland rice

• P may be applied as basal and incorporated.

• When the green manure is applied, rock phosphate can be used as a cheap source of P fertilizer. If rock phosphate is applied, the succeeding rice crop need not be supplied with P. Application of rock phosphate + single super phosphate or DAP mixed in different proportions (75:25 or 50:50) is equally effective as SSP or DAP alone.

N management through LCC for transplanted puddled lowland rice

1. Time of application is decided by LCC score.                                                                                      

2. Take observations from 14 DAT in transplanted rice or 21 DAS in direct seeded rice.

Split application of n and k for transplanted puddled lowland rice

1. Apply N and K in four equal splits viz., basal, tillering, panicle initiation and heading stages.

2. Tillering and Panicle initiation periods are crucial and should not be reduced with the recommended quantity.

3. N management through LCC may be adopted wherever chart is available as given below.

Nutrient management for transplanted puddled lowland rice

Application of organic manures :

1.Apply 12.5 t of FYM or compost or green leaf manure @ 6.25 t/ha.

2. If green manure is raised @ 20 kg /ha in situ, incorporate it to a depth of 15 cm using a green manure trampler or tractor.

3. In the place of green manure, press-mud / composted coir-pith can also be used.

Stubble incorporation :

1. Apply 22 kg urea / ha at the time of first puddling while incorporating the stubbles of previous crop to compensate immobilization of N by the stubbles.

Mat Nursery in Punjab

 

1. Mat nursery is used, if the crop is to be transplanted using manual or self propelled paddy transplanter. To plant 1 ha (with 2 seedlings/hill at 20 x 15 cm spacing), use 30-35 kg good quality seeds (i.e., >80% germination and establishment).

2. Good seeds result in more uniform germination, better vigour of plant, less incidence of micro nutrient deficiency and insect-pests, good smothering effect on weeds and ultimately improved yields.

Types of nursery grown in the Punjab State

 

1. To plant 1 ha (with 2 seedlings per hill at 20 cm x 15 cm spacing), use 20 kg good quality seed (with > 80% germination and establishment).

2. Prepare 400 m2of nursery for each 1 ha to be planted. Apply 30-35 t/ha of well-decomposed organic manure and 65 kg urea/ha and 150 kg SSP/ha at the time of last puddling.

Management of aged seedlings for transplanted puddled lowland rice

1. Follow the spacing recommended to medium and low fertility soil.

2. Plant one or two seedlings per hill.

3. Avoid cluster planting of aged seedlings, which are hindering the formation of new tillers.

4. New tillers alone are capable of producing normal harvestable panicle. Weak panicle may appear in the mother culm within three weeks after transplanting and vanishes well before harvest.

5. To encourage the tiller production, enhance the basal N application by 50% from the recommended and thereafter follow the normal schedule recommended for other stages.

Land Preparation

1. Application of FYM helps to save N fertilizers. Green manuring by dhaincha /cowpea/sunhemp especially in loamy sand to sandy loam soils helps in getting higher yields and also ameliorates iron deficiency in rice.

2. A well pudled field should be obtained to reduce water through percolation, to maintain good seedling vigor and to control weeds, Laser land leveller for precision land levelling should be used to enhance on farm water use efficiency and other farm inputs.
