Climate Change, Natural Mutation and Organic Edamame Production under Marginal Fertility Condition in Richmond, BC
Prof. Krishna P Sharma, PhD, Volunteer
This is a summarizing document to provide a verification support to the edamame (Glycine max (L.) Merr L.) study reported from 2009 – 2015 as an effort to help meet the mission of The Sharing Farm and Richmond Food Security Society. The 2016 study was designed using (a) segregating populations of spontaneous mutations identified and developed at The Sharing Farm, (b) varieties tested for adaptation at Richmond agro-climate, and (c) appropriate technology for local seed production. Studies were planted during the second week of May 2016 utilizing residual organic fertility from previous organic onion crop. Three feet long rows spaced 2 ft. apart were hand planted with 15 seeds. Single rows of the families of four segregating populations and five rows of adapted varieties plus four breeding lines made experimental units for comparative performance test. Plant growth status was closely and frequently monitored and any deviation from normal growth was recorded. Frequent showers and weeding kept the nursery moist and clean. However, health and vigor of seedlings which began to decline at seedling stage, continued to decline beyond 45 days after planting resulting into stunted growth associated with leaf yellowing and puckering of terminal growth – a complex cause of disease and nutrient deficiency. Severity increased irrespective of crop husbandry practices applied except nutrient amendment.
Since plants were approaching the reproductive phase, an alternative husbandry that included physical and spiritual discourse was thought and adopted. Residual soil nutrients from inter row spaces were pulled and piled up around root zone and hose irrigation was applied as physical discourse. Positive thoughts of love and care was mentally created and radiated to the plants, as spiritual discourse, to enliven the inner intelligence to increase efficiency of physiological functions in order to adapt the existing growing environment – Vedic farming approach. The plants started showing the symptoms of recovery as expected and recovered normal growth in 20 days after spiritual discourse that was maintained until harvest. Green pods were harvested between 90-120 days depending on pod maturity of different varieties. Green pod samples were kept in cold storage for quality testing. Rows of segregating populations were rated and harvested as seed matured. Range and means of each parameter were presented to illustrate magnitude of variation between and within population and families. Statistical analysis was not performed because of no replication.
The result confirmed previous observations and provided new insights “the silent discourse” for future research. Spontaneous mutant populations from M2 to M4 generations provided strong evidence that locally adapted high yielding genotypes with different traits of interest can be developed. Varieties and breeding lines with high yield and high quality marketable pods that justify economic viability have been identified. More than 40 promising genotypes from segregating families with different seed color and dry seed weight 40-46 gm/100 exceeding parental performances are selected and pedigree records are maintained. As genes are eroding from nature, proper stewardship of these valuable genetic resources is needed for conservation, evaluation and utilization. In conclusion, this study has added strong support to previous findings that edamame can be a potential health promoting crop in few suitable pockets of British Columbia including Vancouver Lower Mainland
