Mineral nutritional deficiencies and imbalances are emerging as major threats now-a-days in the Indian banana production scenario. Lack of awareness among the farmers about the importance of balanced fertilization has led to indiscriminate application of certain nutrients which has caused deficiency of micronutrients. In addition, non-availability of good quality organic manures is also one of the factors for poor soil health. Particularly, the micronutrients are very much neglected among the banana farming community in India and essentiality of micronutrients in banana production is gaining importance. Keeping this as a challenge, the National Research Centre for Banana, Trichy, Tamil Nadu under the Indian Council of Agricultural Research (ICAR), New Delhi has focused its research programme on micronutrient requirements of banana. Based on the various research findings enunciated from different soils and locations, it has formulated a micronutrient mixture named Banana Shakti, in 2007. Now, this mixture has been widely accepted by the farmers in many banana growing regions like Tamil Nadu, Maharashtra, Karnataka, Andhra Pradesh, Kerala, Gujarat, Uttar Pradesh and Bihar and gained popularity among the banana farming community.
HOW TO APPLY TO BANANA CROP?
- If the soil pH is more than 8.5, foliar spray of 2% Banana Shakti with wetting agent at 4, 5 and 6 months after planting is recommended.
- If the soil pH is less than 8.5, soil application of 10g Banana Shakti per plant at 3 months after planting is recommended.
ADVANTAGES OF BANANA SHAKTHI
- It corrects the micronutrient deficiency and increases the availability of macro and micronutrients to banana crop, thereby increases the productivity by 15-20%.
- Increases the TSS of fruit and decreases the acidity of fruit, Improves the quality of fruit like taste, sweetness, flavour and aroma.
- Provides an additional net profit of Rs.20,000 to 25,000 per hectare with Benefit to Cost ratio of 3.6 : 1.
Three Suckers Per Hill
- Bunch covering with 100 gauge white polythene sleeves with 4-6% ventilation after the last hand opening improves the bunch quality.
- Banana fingers packed with foam in two-ply cardboard boxes weighing 13.5 kg with ethylene absorbent is suitable for export.
In banana and plantain cultivation, four major nematodes cause extensive damage to the root system there by affecting the uptake of water and nutrients from the soil. Due to that 30-40% yield loss has been reported. Indiscriminate use of nematicides has proved disastrous to the environment and human health. Hence, effective bio-control agents like Paecilomyces lilacinus, Pseudomonas fluorescens have been identified at NRC Banana for the management of major nematodes in banana. These bio-control agents are found to be very effective in controlling these nematodes and increasing the growth and yield of banana.
- Formulation : Dried Banana leaves / Talc powder.
- Colony Forming Unit : 1x109cfu/g.
- Method of Application : 30g / plant applied around the basin at the time of planting and the same dose at 3rd and 6thMAP .
- Eco-friendly approach.
- Induces better plant growth and uptake of nutrients due to better root system.
- Enhancement of crop yield and decreases the infection of banana major nematodes.
Banana weevil attack has been reported to interfere with root initiation, kill existing roots, limit nutrient uptake, reduce plant vigour, delay flowering and increase susceptibility to other pests and diseases. Yield reductions are caused by both plant loss (plant death, rhizome snapping, toppling) and lower bunch weights. Toppling, more commonly attributed to nematodes, has been observed under conditions of high weevil attack in the absence of nematodes. The NRCB isolate of Endophytic entomopathogenic (insect killing) fungus Beauveria bassiana can be prepared under farm house conditions. The conidiospores of Beauveria bassiana is prepared in a nutrient solution which helps the fungi to survive for a longer period and enhances the shelf life and sustains the conidiospores without any loss over a period of two years to control banana weevils (Banana corm weevil and Banana stem weevil) infesting on banana and plantains.
- Banana pseudostem trap @ 100/ha effectively controls banana weevils.
- Swabbing the cut surface of the traps with Beauveria bassiana or Heterorhabditis indica @ 20g trap-1 trapped the weevils and killed them instantly and they need not be collected.
Bananas are affected by four major viruses such as Banana Bunchy Top Virus (BBTV), Banana Streak Virus (BSV), Cucumber Mosaic Virus (CMV) and Banana Bract Mosaic Virus (BBrMV). These viruses cause serious diseases and are a major constraint to banana tissue culture industry. In quality production of tissue culture banana plants, virus indexing plays a major role to ensure the plants are free from viruses.
Molecular Plant Virology lab, NRC for Banana, Tiruchirappalli has been Accredited for testing tissue culture raised plants for major virus diseases of banana as Accredited Test Laboratory (ATL) under National Certification System for Tissue Culture Raised Plants (NCS-TCP) by Department of Biotechnology (DBT), GOI .
Detection of four banana viruses by simplex, duplex and multiplex -PCR Lane M: 1Kb ladder Plus; Lane 1: BBTV (500bp) and BSV (480bp); Lane 2: BBrMV (300bp) and CMV (657bp); Lane 3: BBTV (500bp), BSV (480bp), BBrMV (300bp) and CMV (657bp); Lane 4: Negative control.
- Well designed primers for all four viruses are available for commercial exploitation.
- Indexing can be done using PCR for TC plants for certification.
- PCR based technology developed at NRCB has been applied for virus indexing of more than 26,000 samples received from more than 20 Banana TC Industries.
- Nucleic acid probes (non-radioactive) are also available for NASH test.
Cucumber Mosaic Virus (CMV) and Banana Bract Mosaic Virus (BBrMV) cause serious losses in banana leading to reduction in productivity. Early detection of these two viral pathogens through ELISA based tools would pave a way for the production of healthy planting material through Tissue Culture.
- Production of banana virus free quality tissue culture plants can be ensured.
- Banana farmers, tissue culture industries will be benefited.
- Useful in epidemiological studies and for crop improvement and phytosanitary programs.
- Banana productivity can be increased by minimizing the yield loss due to viruses.
- Antiserum can be used for certification programme for TC plants.
- Expressed viral protein can be used for developing monoclonal antibodies.
- Can be exploited for lateral flow (dip stick) technology development.
Banana wilt disease caused by Fusarium oxysporum f. sp. cubense is one of the most important disease threats to banana production, causing disease incidence of 30% in main crop and upto 85% in ratoon crop. The disease is serious in Tamil Nadu,Karnataka, Andhra Pradesh, Kerala, West Bengal, Assam and Bihar states. Severe disease incidence has been noticed in cultivars like Rasthali (AAB), Karpuravalli (ABB), Monthan (Cooking bananas-ABB), Virupakshi (Hill banana AAB) and Neypoovan (AB).
A potential strain Trichoderma viride NRCB-1 isolated from Wayanad area of Kerala has the capacity to arrest the mycelial growth of the wilt pathogen. The strain can be multiplied either in rice chaffy grain or using dried banana leaves to a population of 6 X 1031cfu/g. The product can be stored under room temperature (30 deg. C) for 6 months.
