Agricultural Research Station, Yellamanchili was established in 1960 in a
village Kokkirapalli to cater the needs of sesame growers of the region. The station is located 5km north of Yellamanchili and 22 km south of Anakapalle. The station is also working on groundnut to identify suitable variety to the north coastal districts of A.P.
Area of the farm (Gross) - 6.96 ha.
(Net) - 5.20 ha.
Constriants in Sesame and groundnut production :
| Sesame: |
The optimum time of sowing in coastal region is second fortnight of May during kharif and first fortnight of January during rabi/ summer. Late sowing results in severe incidence of phyllody both in kharif and rabi seasons. Alternaria leaf spot and powdery mildew are also contributing to lower the sesame yields during kharif and rabi respectively, besides pests like leaf webber and capsule borer in both the seasons. Shattering of the seed in the filed is another problem. |

|
| Groundnut : |
The present bunch varieties viz. TMV -2, and JL - 24 produce excessive vegetative growth and elongation of stems resulting in most of the pegs hanging in the air without reaching the soil to become pods leading to low yields. The factors that are contributing to the excessive vegatative growth are high rainfall ( 1000-1200mm), more number of cloudy days and high humidity ( 70-90%) during rainy season. Pests like leaf webber and sucking pest complex and diseases like leaf spot, collor rot and rust are some other constraints. |

Objectives of the research station :
In view of the problems being faced in sesame and groundnut in north costal districts of Andhra Pradesh the research station is oriented with the following objectives.
i)To evolve sesame varieties with high yield, high oil and earliness , tolerant to alternaria leaf spot and phyllody suitable to Andhra Pradesh with special reference to north coastal districts.
ii)To identify high yielding groundnut varieties suitable to north coastal districts of Andhra Pradesh.
