Evaluation of drought tolerant Groundnut varieties: Groundnut varieties viz., TPT-25 (Abhaya), TCGS.APNL-888(Greeshma) & ICGV-91114 were tested for two years in low rain fall areas during kharif under rain fed conditions. The variety ICGV -91114 performed well in L.R Palli division and it has been spread in an area of 40 ha. The varieties TPT -25 & Greeshma performed well in black and red soils of Thondur, Vempalli, C.K Dinne and Pendlimarri mandals. These varieties were grown in area of 100 ha. 


Field bean (TFB-5) as intercrop in Groundnut (1:10):

   The performance of field bean variety TFB-5 was satisfactory and is suitable for rain fed alfisols as an intercrop in Groundnut.  An additional income of Rs. 15000/- per hectare was obtained with field bean.


Seed guar as intercrop in red gram as an alternative to groundnut in rainfed alfisols:

Seed guar as intercrop in red gram was identified as best alternative to groundnut in rain fed alfisols. Yields were encouraging and cost of cultivation can be reduced. If suitable marketing or seed collection centers are developed, the crop can be encouraged.


Soil test based fertilizer application in paddy (NDLR-8):

The trial was conducted in 04 locations at Upparapalli village of Chennur mandal. Among the 04 locations highest yield was recorded in soil test based fertilizer application plot (4693 kg/ha) followed by recommended dose of fertilizer application plot (4623kg/ha) as compared to farmers practice (4075 kg/ha). In soil test based fertilizer application plot 1.5% increase in yield over the farmers practice was observed.


Testing of improved Onion varieties with suitable method of sowing: 

The trial was conducted in Muddanur, Pendlimarri and KVK farm. Among the two methods Ridge and furrow method of sowing had given higher yield (10303 kg/ha) than the Bed method (8775 kg/ha).The additional net income obtained from Ridge & Furrow method of sowing was Rs 30420/- per hectare and there was 17.4% increase in yield over bed method.



Weed control with Herbicides in Groundnut :

The highest net returns obtained from the pre emergence application of Pendimethalin + post emergence application of Quizalofop ethyl at 30 DAS followed by pre emergence application of Pendimethalin + one hand weeding at 30DAS and manual weeding  of Rs. 3864/ha, Rs 3236 and Rs 401/ha respectively.


Performance of Gingelly varieties:

Locally adopted cultivar Gouri is highly susceptible to Phyllody resulting in often crop failures. KVK, Utukur introduced Black seeded varieties YLM-66 & YLM-11 and white seeded varieties Chandana and Swetha Thil. Except chandan all the other three varieties performed satisfactorily and the area under Sesamum cv. Gowri was replaced with YLM-66, YLM-11 and Swetha thil.


Initiation of regular flowering in alternate bearers of mango (Baneshan):

Majority of the farmers growing alternate bearing varieties like Baneshan due to which farmers are not getting regular encouraging yields. To initiate regular flowering, the following technology was given to the farmers and observed 15 -20 % yield increase. Mango growers are now practicing the pruning technique in alternate bearers like Baneshan.

a. Pruning of fruited twigs (2cms back) after harvesting.

b. Foliar spraying of KH2PO4 @ 2 g./l immediately after pruning. 

c. Application of recommended dose of fertilizer.


Introduction of New varieties in Chrysanthemum:

Chrysanthemum is of the most traditional flower crop in Kadapa district and the locally adopted cultivar effected with biotic stresses like root rot, leaf spot, nematodes resulting in low yields and low market prices. Under this circumstances KVK, Utukur introduced 8 varieties. Among them Purnima (White), Shanti, Indira performed well with relative tolerance to Leaf spot and Root rot diseases and recorded 40 percent higher yields when compared to local cultivar. Area under Chrysanthemum is being replaced by these varieties.


Introduction of New of new commercial flower crop China Aster cv. Kamini:

New commercial flower crop China aster cv. Kamini was introduced in Kadapa district during 2009-10 to catch the advantage of commercial trade. The performance


of the crop is satisfactory and realized the returns Rs. 60,000 to 70,000 per acre and the crop is tolerant to root rot and leaf spot deseases. Area under this crop is increasing gradually year by year. 

Supplementation of Azolla as cattle and poultry feed:


Cultivation and feeding of Azolla to milch animals as protein supplement was introduced during the year 2005–06. Supplementation of Azolla to milch animals in the ration increases the milk yield up to 25-30% when compared the farmer’s method of no feeding of concentrates. With this result, the cultivation of Azolla and feeding to the milch animals was popularized through Front Line Demonstrations and established 250 Azolla units in coordination with the Department of Animal Husbandry during the year 2007-08. Now more than 500 farmers of Kadapa district adopted the technology. More over the farmers from other districts of Andhra Pradesh are coming forward for Azolla culture. A visual CD on this technology was developed and got good appreciation from the University as well as Project Zonal Coordinator.


 Rearing of improved colored birds as back yard poultry:


Rearing of Vanaraja birds as backyard poultry was introduced by conducting Front Line Demonstrations during the year 2006-07. Van raja chicks aged 6-8 weeks were supplied to the farmers to rear in the backyards. The birds gain more than 2kg body weight within six months. With this result these birds attracted the farmers. More than 2000 Vanaraja chicks were supplied to the farmers during the period under report in coordination with the Department of Animal Husbandry, Kadapa under C.M. Package. Women farmers are getting Rs.3700/- through rearing of 10 Vanaraja chicks for one year by selling eggs and birds.
