Title of On farm Trial

Induction of regular and early flowering in Mango through Paclobutrazol.

2.

Problem diagnosed

The farmers face the problem of  alternate or irregular bearing generally signifies the tendency of mango trees to bear a heavy crop in one year (On year) and very little or no crop in the succeeding year (Off year)

3.

Details of technologies selected for assessment/refinement

(Mention either Assessed or Refined)

1. Farmer Practice (FP): No use of hormones.
2. Technology option-I (TO₁) : Application of Paclobutrazol@ 1.0g a.i./m  effective canopy  (0.25g/plant) as soil drench during Oct-Nov
3. Technology option-II (TO₂) : Application of Paclobutrazol  @ 1.5g a.i./metre effective canopy (30- 45g) canopy diameter as soil drench during September

Title of the OFT

Eco-friendly management practices to control fruit fly in cucurbits.

2.

Problem diagnosed

Most of the fruit of cucurbits damage due to fruit fly, ultimately yield affected and farmers indiscriminate use hard insecticides which is harmful for human. 

3.

Technology for

Testing:

Farmers practice- Use of any pesticides as per their knowledge.

TO1- Commercial fruit fly pheromone trap @ 10/h.

TO2- Self made poison bait fruit fly trap @ 10/h.

Title of the OFT

Management  of Phytophthora heart rot and root rot disease in pineapple

2.

Problem diagnosed

Heart rot and root rot one of the major disease caused by Phytophthora parasitica and P. cinnamoni is the most serious problem in all the pineapple growing area. So development of  integrated disease management technology is very necessary.

3.

Technology for

Testing:

TO1- (i) Soil application of Trichoderma sp. @ 5 Kg/ha with FYM

         (ii) Fosetyl AL @ 1000 ppm bi-monthly spray with first spray after two month of planting.

TO2- (i) Soil application of Trichoderma sp. @ 5 Kg with FYM 

          (ii) Mancozeb @ 2000 ppm and Difenconazole @ 1000 ppm alternate bi-monthly spray with first spray after two month of planting.

3.

Problem diagnosed

Excessive use of chemical fertilizer and Spiraling price of urea leads to increase in cost of cultivation

4.

Technology for

Testing:

Farmers practice- RDF (100:40:20) Kg/ha

TO1- 50% of RDN & 100% PK + nano urea @4ml/lt. water (Single spray at pre flowering stage).

TO2- 50% of RDN & 100% PK + 2 sprays of Nano Urea at (25 to 30 days) and (60-65 days) @ 4 ml/lt water.
