Tissue Culture-Banana

Water Management

Banana, a water loving plant, requires a large quantity of water for maximum productivity. But Banana roots are poor withdrawal of water. Therefore under Indian condition banana production should be supported by an efficient irrigation system like drip irrigation.

Water requirement of banana has been worked out to be 2000mm per Annum. Application of drip irrigation and mulching technology has reported improved water use efficiency. There is saving of 56% of water and increasing yield by 23-32% under drip.

Irrigate the plants immediately after planting. Apply sufficient water and maintain field capacity. Excess irrigation will lead to root zone congestion due to removal of air from soil pores, thereby affecting plant establishment and growth. And hence drip method is must for proper water management in Banana

Fertigation

Banana requires high amount of nutrients, which are often supplied only in part by the soil. Nutrient requirement has been worked out on all India basis is to be 20 kg FYM, 200gm N; 60-70gm P; 300gm K/plant. Banana requires heavy nutrition. Banana crop requires 7-8 Kg N, 0.7- 1.5 Kg P and 17-20 Kg K per metric tonne yield. Banana responds well to application of nutrients. Traditionally farmers use more of urea and less of phosphorous and potash.

In order to avoid loss of nutrients from conventional fertilizers i.e. loss of N through leaching, volatilization, evaporation and loss of P and K by fixation in the soil, application of water soluble or liquid fertilizers through drip irrigation (fertigation) is encouraged. A 25-30% increase in yield is observed using fertigation. Moreover, it saves labour and time and the distribution of nutrients is uniform.

Schedule of Application

The fertilizer schedule for tissue culture banana variety Grand Naine both in solid and water soluble form is given in the tables below:

Schedule is directive only and may change according to planting season and soil fertility status (Soil analysis)
 SSP = Single Super Phosphate, MOP = Muriate of Potash.
