Package & practices of groundnut

The groundnut (Arachis hypogaea L) which ranks 13th among the principal economic crops of the world, is an important food legume and oil seed crop of tropical & subtropical areas. In India, it is the most important oilseeds crop and has the largest area (32 %) in the world.

 

Soil Management

Groundnut crop does best on well drained, light textured loose and friable soil having reasonably high calcium, pH 5.5 to 7.0, and a moderate organic matter. Make good tilth of soil with 2 ploughing to obtain optimum germination. In terrace and flat land of high rainfall areas, raised beds of 10-15 cm height are to be prepared to avoid water- logging problems.

Manures & Fertilizers.

FYM = 5 - 10t/ha

N     = 40 kg / ha

P205= 60 kg/ha

K20  = 40 /ha

All these amount of NPK should be placed in the furrows below the seed at sowing. Furrow application of lime at 2 t /ha as CaCo3 or CaSo4 every year is recommended. Gypsum at 500 kg/ha at the time of flowering should be applied to supply Ca + S to groundnut. Soil application of 10 kg Mg So4 corrects Mg deficiency.

Irrigation and drainage

 Generally there is no moisture stress and irrigation is not required for groundnut as there is ample rainfall during its growing period (Kharif). But in dry years irrigation at pre-sowing, pegging and pod formation are recommended, if there is no rain during these stages.

To maintain good crop and avoid damage to root system, drainage is essential. It should be grown on ridge and furrow system made parallel to the slope. Groundnut grown on bunds produces highest yields.

Weed management

 The weed infestation is a severe problem of groundnut during kharif season due to high rainfall. It is essential to keep the weed free upto 60 after sowing (DAS), as the maximum damage is caused during this period and removal of these weeds by hand within upto 60 DAS results in the highest net returns. One weeding and hoeing or earthing up of soil and 25DAS followed by one hand weeding at 40DAS found to be effective and economical.

Insect pest and disease management

Insect pest

Major insect pest of groundnut are leaf folder, leaf miner, red hairy caterpillar, leaf hopper, flower beetles, white grubs, termites and mealy bugs.

Control:

Decamethrin and Monocrotophos are effective insecticides against leaf folders, leaf miners and white fly. The thrips infestation and collar rot of groundnut are reduced by decis (0.003%) spray and barvistin seed treatment. For leaf eating pests carbaryl (0.1%)and for sucking pest monocro- tophos, quinolphos and methyl parathion all at 0.5% in effective, use of aldicarb is effective against red borers and soil pests. To avoid damage by the leaf miner, set up light trap for attracting and destroying moths.

Disease

Early leaf spot (Tikka), late leaf spot and rust are major disease of groundnut

Control

1.Tikka disease: Spray bavistin 0.05%+Dithane M 45 0.2% at 2-3 

weeks intervals for 2-3 times starting 4-5 weeks after sowing

2.Treat the seeds with thiram@3g/kg seed a bavistin 2g/kg seed before sowing to avoid color rot

3.Use high yielding disease tolerant genotypes 

4.Spray fungicide mixture of carbendazim 0.05% + manozeb 0.2% upto  to 50 DAS to control leaf spot

Harvesting :

The bunch varieties mature in about 120-135 days and the semi-spreading in 130-145 days. At maturity, the pods became hard and tough and inside shell surface becomes rough with net venation. Harvesting before maturity, lower yield oil percentage and quality while delay in harvesting, results in stem rot and weakening of pegs therefore it is important to harvest at the right time. The produce is dried in seen as quickly possible to bring down the moisture content by 5-7%.

Success Stories

Cultivation of off season cucumber

Cultivation of off season cucumberCucumber has been traditionally cultivated by Naga farmers in their jhum fields as a mixed crop during the Kharif season (April to August). It is one of the important component crops in the Jhum field and the harvest is used, mostly for household consumption and sometimes sold at the local market. Kharif crops of cucumber are harvested during...
