Varieties under Pipeline

Bread fruit (AA 2)

            Accession AA.2 was found to be superior with an yield of 75.0 kg per tree  (237 fruits).


Technologies developed


     100g of Azospirillum, 100g N, 40g P, 140g K and 10kg FYM per vine per year registered higher yield of 1.95 kg dried berries per vine in the cultivar Panniyur-1.


     An espacement of  3 x 3m recorded a maximum yield of 3.9kg of green pepper per vine in Panniyur-1.

     Application of monocrotophos 1.5 ml/l was found to be effective in controlling the mealy bug Ferrisia virgata in pepper.

     Pre and post monsoon soil and foliar application of Pseudomonas  fluorescens (50g) and post monsoon application of neem cake (2 kg) + metalaxyl 0.1 % were found to reduce the incidence of foot rot in black pepper.



     Soil application of Phorate 60g/tree or trunk implantation of Monocrotophos 1ml/tree was found to be effective for the management of stem borer  Sahyadrassus malabaricus on clove.

     Spray application of Monocrotophos 1.5 ml/ha. or dimethoate 1ml/l as found to be effective for the management of the black scale Saissettia nigra on clove.    


     Dipping hardwood cuttings of Allspice in 1000ppm of IBA/IAA before planting in polybags gave maximum rooting.



      Rhizome treatment and soil application of Metalaxyl MZ  ( 0.1%) + Pseudomonas fluorescens  at 45 and 90 days after planting was found to reduce the rhizome rot incidence upto 4.2 per cent.


     25 kg of FYM, 25 g of ZnSo4, 500g of Neem cake per plant was found to correct zinc deficiency in Red banana.

     Pseudostem injection of monocrotophos or dimethoate @  1 ml + 5ml water mixture administered @ 4 ml/plant was found to be effective for the management of pseudostem borer on banana.  The cost benefit ratio was 1:2.85 and 1:2.79 in the case of Monocrotophos and Dimethoate respectively.

     Spraying Mancozeb 0.25 per cent starting from 3rd month onwards with one month interval registered 18.8 per cent incidence of leaf spot as against 65.2 per cent in control.


     Application of 25t of FYM, 800:40:650kg of NPK/ha registered higher yield and TSS.

     A spacing of60 x 30 cm recorded the highest yield of 52 t/ha. with a maximum fruit length of 20.5 cm and fruit girth of 42.5 cm.


     Application of NPK @ 50:65:125kg/ha recorded maximum tuber yield.
