export oriented agriculture principle investigator: S.Eswara Reddy, Ph.D Sr.Scientist(Hort)

Trials conducted during 2005-2006  Evaluation of vanilla at different spacings under polyhouse conditions for export  Vanilla cuttings were planted at a spacing of 1x1m,1.5x1.5m,2x2m,and 2.5x2.5 m.

Data on Vegetative growth parameters a)

Number of leaves /vine spacing (mts) 1x1 m : 1.5x1.5m : 2.0x2.0m : 2.5x2.5m :

b)

19.61 21.07 22.51 19.88

Vine length (cm) 1x1m : 1.5x1.5m : 2.0x2.0 m : 2.5x2.5 :

81.53 cm 103.46 cm 98.12 cm 112.14 cm

Present recommendations, knowledge and justification : In recent years vanilla prices have sky rocketed in the International Market. Now the present situation in the World market with regard to vanilla essence has tremendously increased, Hence there will be good demand for the natural vanilla There fore to evaluate vanilla it different spacing the investigation is designed.

Techniques to be adopted : a) Design : RBD b) Treatments : Four Spacing at 1 x 1 mt, 1.5 x 1.5mt, 2 x 2 mt, 2.5 x 2.5 mt c) Replications : Four d) Plot size : Five vines / treatment will be used to collect data.

Data on Vegetative growth parameters a)

Number of leaves : 1x1 m : 19.61 1.5x1.5m : 21.07 2.0x2.0m : 22.51 2.5x2.5m : 19.88

Expected benefit to farmers on adoption : Optimum number of vines can be grown in unit area and the income of farmers can be increased by judicious utilization of space in the polyhouse

justification Vanilla is being grown in Visakhapatnam, Vizianagaram districts of north coastal zone,due to the encouragement given by Department of Horticulture. However, there is no scientific knowledge generated and technology available on vanilla and inter crops in it with ANGRAU. The information generated through this experiment will fill the gap

progress  A polyhouse was constructed at a cost of 2.5 lakhs  A shade net was established at a cost of 20,000 rupees to multiply vanilla cuttings  Foggers were fitted in the polyhouse to regulate temperature  Drip irrigation was installed in the polyhouse to irrigate vanilla plants.

DEVELOPING AGRO TECHNIQUES FOR GUAR

 Guar, or cluster bean, (Cyamopsis tetragonoloba (L.)) is a drought-tolerant annual legume crop. India accounts for 80% of the total guar produced in the world and 70% is cultivated in Rajasthan. Apart from Rajasthan, it is being grown mainly in Gujarat, Haryana and Punjab. It is also grown in some parts of Uttar Pradesh and Madhya Pradesh.

PROGRAM FOR 2006-07

Work done during 2005-2006  Performance of 20 guar varieties was evaluated for their suitability to north coastal zone.  The varieties are RGM-111, RGC-936,HGS-884,GG-1,G-36, GAUG004,GAUG-9005,GAUG-9003,HG-563,RGC1002,G-986,RGM-112,G-16, G-42,RGC-1025,G-39,G-28,G-3,G-4,G-5

 RGM-111 performed well over other 19 varieties under evaluation.  Yield and yield characters of RGM-111  Seed yield (kg/ha) : 639.75  Days to flowering : 28. 7  Maturity (days) : 75.1  Plant height (cm) : 63.52  No.of branches/plant : 6.26  No of pods/plant : 46.89  No of seeds/pod : 7.34
