Production Technology of Pea


Botanical Name: Pisum sativum L. 

Family: Leguminosae. 

Importance 

Pea is an important vegetable and generally cultivated for its green pods. It is highly nutritive and is rich in protein. It is used as a vegetable or in soup, canned frozen or dehydrate. It is cooked as a vegetable along or with potatoes. Split grains of pea are widely used for dal. Pea straw is a nutritious fodder. 

Variety 

BARI motor 1 is the high yielding variety in Bangladesh.

Early Variety: Early Bejar, Arket.                   Mid-season Variety: Bonevilla, Jawahar. 

Climate 

Pea is a cool season crop and performs best at 10o C to 18o C. The flower and young pods are badly affected by frost. The germination of seeds takes place at 3.3o C soil temperature. Boswell (1920) reported that as the temperature increases during the growing season the yield decline sharply. The optimum mean monthly temperature for pea is 12.8o C to 18o C. 

Soil 

Pea can be grown on a wide range of soil types, from light sandy to heavy clay. Field pea has moisture requirements similar to those of cereal grains. However, peas have lower tolerance to saline and water logged soil conditions than cereal grains. Peas will not survive long in water logged conditions. Poorly drained and saline soils should be avoided when growing field pea. 

Sowing of Seed 

Sowing Time: Generally pea sown as relay crop into Amon rice. The pea is generally sown in Rabi season from the beginning of October to mid of November. Sowing of seed during the first week of November is proper time to get higher yield. 

Seed Rate: The optimum seed rate is 25 to 30 kg/ha. As relay crop, it required some more. 

Method of Sowing: The pea is generally sown by broadcasting. But it may also be sown by dibbling or behind the plough. The seeds are soaked in water overnight before sowing for better germination.  Seeds treated with Rhizobium culture give higher yield. Pal Sodkar et al. (1974) reported with soaking of seeds in G. A 10 ppm for 12 hour gave the highest germination and yield. 

Layout and Spacing: Flatbed layout is used. Spacing is 45 X 20 cm.

Fertilizer Application

Fertilizer                  Amount (Kg/ha) 

Urea                        40-­45

TSP                          80-­85 

MoP                       55-­60 

Zinc Sulphate       7­-7.5 

Borax                     7­-7.5

All fertilizer should be applied during final land preparation.  

Intercultural Operation 

Trailing and Staking: This is an important operation to be done when vines were about two month old and are at spreading stage. Generally the plants should be supported on bamboo sticks. Delay in this operation will reduce the yield considerably. 

Weed Control: It is very difficult to control the weeds by mechanical methods as the crops are sown in rows in closed spacing. Uses of herbicides have been proved very such effective. Atrazine,  propazine and simazine @ 0.54 kg per acre gave good broad leaf weed control. Prometryne @ 400 g per acre was most effective in improving vegetative growth and yield of pods. 

Irrigation 

Water requirement of pulse crops are higher than cereals. The water requirement of pea depends largely on Agronomic condition of the locality. The crop may be irrigated at both 10 days interval.  Where rainfall is low, peas irrigation is very necessary at flowering and grain development stage. 

Disease and Pest 

Main disease of Pea are Blights, Root Rots, Stem Rot, Powdery Mildew etc. Main Insect Pest are Pea Aphids, Lygus Bug, Grasshoppers etc. They control by taken proper management practices.  

Harvesting

Maturity symptoms: Peas are harvested for table use when the pods are will fill and the young tender peas changing in colour from dark to light green. 

Time: Peas may be picked in 45 to 60 days, 75 days and 100 days according to early, Mid-season and  late  airtimes  respectively.  Fresh unshielded peas may be kept 90­-95% relative humidity.  Mid February to Late February is harvesting time for BARI motor 1. 

Yield 

·         BARI motor 1: 1.2 ton/ha.     

·         Early Variety:  25 to 40 Quintals/ha. 


            ·         Mid-Season and Late: 50 to 60 Quintals/ha

Methods of Fertilizer Application. https://cststudy.blogspot.com/ B.Sc.Ag. (Hons) Part-I  Methods of Fertilizer Application Fertilizer recovery is greatly influenced by method of its application. Method of application varies according to the spacing of crop, type of fertilizer material, time of application, etc. A brief account of these points could be explained as under : A.Method of application of solid fertilizer materials Solid materials may be applied in following ways: 1. Broadcasting Even and uniform spreading of dry solid fertilizers by hand or spreader over the entire field before or after sowing of the crop is termed as broadcasting. Well decomposed FYM, compost, oil cake, bone meal, urea, superphosphate and lime are applied by this method. Advantages This method is easy, less time taking, cheap and more convenient to the farmers. This method proves effective- i.                      When the crops have a dense stand ii.

Seed dormancy and its importance. https://cststudy.blogspot.com/                                                Seed Dormancy Definition:   The term dormancy refers to lack of growth in any plant part due to either internally or externally induced factors. Seed technologist use the term of refers to non-germination resulting from conditions within the seeds.  Dormancy is the state of inhibits growth of seeds or other plant organs as a result of internal causes not due to environmental condition. In other word, the unavailability of well developed mature, perfectly viable and healthy seed to germinate when placed under favorable conditions for germination is called dormancy or rest period of seed. Important of seed dormancy: 1. It is a mechanism which helps to survive this species. 2. It prevents the germination of seed in the field during production. 3. Dormancy helps to store the seed in the store house. 4. It contributes the congivity of the species.

New Update Mango Hopper, Mango Defoliator, Banana Leaf and Fruit beetle, Citrus Caterpillar/ Lemon Butterfly, Rhinoceros Beetle of Coconut

Mango  Hopper.https://cststudy.blogspot.com/ Mango  Hopper 1. Idocerus alkinsoni. 2. I. niveosparus. 3. I. clypealis. Family : Cicadellidae. Order : Hemiptera. Nature of Damage 3 species of hopper causes serious damage to the inflorescence. Heavy laying on inflorescence causes  dropping and withering of the fruits. Both nymphs and adult suck juice from the flowers, resulting shedding  and withering of the flowers. In case of severe attack, honey dew secreted by the hoppers over the  inflorescence and leaves, giving rise to development. Shoote mold which hinders the setting of fruits. Lose  due to hoppers varies from 25­-60%. Life Cycle 1. The insect appear in large number during November to February as soon the flowers buds beginning to  form. 2. Female are lays egg on leaves flower stick and buds etc. Eggs are laid singly or batch. A female lays on average 200 eggs. 3. The egg hatch in 4­-7 days in winter and 2­-13 days in summer. 4. There are two generations of
