AGRICULTURAL RESEARCH STATION-YELLAMANCHILI, VISAKHAPANTAM- DISTRICT, ANDHRA PRADESH.

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.
