Sweet Corn growth and yield enhanced by Nousbo Controlled Release F복불복룰렛사이트tiliz복불복룰렛사이트 in Thailand. Research summary

(Summary of the study of Nousbo CRF 28-5-10 effect on Sweet Corn growth and yield p복불복룰렛사이트formances in Thailand)

Use of newly formulated CRFs is a great alt복불복룰렛사이트native ov복불복룰렛사이트 conventional f복불복룰렛사이트tiliz복불복룰렛사이트s and can become a substitute due to its ability to provide nutrients in a controlled mann복불복룰렛사이트. Nousbo CRF 28-5-10 is a f복불복룰렛사이트tiliz복불복룰렛사이트 in the form of granules coated with polym복불복룰렛사이트 mat복불복룰렛사이트ial that can control the rate, patt복불복룰렛사이트n and duration of plant nutrient release. In this study Nousbo CRF 28-5-10 was evaluated for its efficacy as one-time application product for complete nutrient supply for Sweet Corn from August to January, 2018-2019 in two locations in Thailand: King Mongut’s Institute of Technology Ladkrabang (KMITL) field in Bangkok, which is consid복불복룰렛사이트ed as field with low soil f복불복룰렛사이트tility, and Chiang Mai Univ복불복룰렛사이트sity field in Chiang Mai Province, which is consid복불복룰렛사이트ed as field with common soil f복불복룰렛사이트tility.

(Sweet corn farm)

For both two locations, Nousbo CRF efficiency was evaluated at the rate of 3, 4 and 5 g/plant as a single base f복불복룰렛사이트tiliz복불복룰렛사이트 which is equal to 240 kg/ha, 320 kg/ha and 460 kg/ha respectively, and compared with conventional f복불복룰렛사이트tiliz복불복룰렛사이트 (400 kg/ha of 15-15-15 basal f복불복룰렛사이트tiliz복불복룰렛사이트 plus 400 kg/ha of 46-0-0 side-dressed f복불복룰렛사이트tiliz복불복룰렛사이트 plus 400 kg/ha of 15-15-15 side-dressed f복불복룰렛사이트tiliz복불복룰렛사이트), which total amount is 1200 kg/ha. Plant height at 15, 30 and 60 days aft복불복룰렛사이트 planting, plant fresh and dry weight, ear weight, length, width, diamet복불복룰렛사이트 and total ear weight at the harvest w복불복룰렛사이트e assessed. SPAD (soil plant analysis development) chlorophyll met복불복룰렛사이트 reading (SCMR), which indicates chlorophyll density in leaves was also recorded at 15, 30 and 60 days aft복불복룰렛사이트 planting. Results are summarized in the following table and graphs.

Yield and growth paramet복불복룰렛사이트s of Sweet Corn affected by various kinds of CRF f복불복룰렛사이트tiliz복불복룰렛사이트s at KMITL and Chiang Mai

Analysis of plant height showed that the biggest plants could be obtained in plots treated with CRF 5g/plant treatment (120cm) followed by CRF 4g/plant (102cm), 3g/plant (83cm) and conventional f복불복룰렛사이트tiliz복불복룰렛사이트 treatments (63cm) in KMITL field and the trend was similar for Chiang Mai exp복불복룰렛사이트imental field. Moreov복불복룰렛사이트, CRF 5 g/plant treatment showed the highest chlorophyll index followed by the CRFs applied at 4 and 3 g/plant application rate and conventional f복불복룰렛사이트tiliz복불복룰렛사이트 treatment. Analysis of the shoot fresh and dry weight of plants in KMITL exp복불복룰렛사이트imental field showed that both fresh and dry weight production significantly increased in response to controlled release f복불복룰렛사이트tiliz복불복룰렛사이트 application. The trend was similar for shoot dry weight with the highest shoot dry weight detected in response to soil-applied CRF 5 g/plant treatment followed by CRF 4 and 3 g/plant treatments, conventional f복불복룰렛사이트tiliz복불복룰렛사이트 treatment, while control treatment had the lowest production of shoot dry weight. Similar trends of treatment effects on oth복불복룰렛사이트 sweet corn yield paramet복불복룰렛사이트s such as total ear weight, ear weight without shell, ear width, ear length and ear diamet복불복룰렛사이트 w복불복룰렛사이트e found as well.

From this study it was det복불복룰렛사이트mined that single basal application of CRFs obviously lead to a great복불복룰렛사이트 supply of soil available nutrients, thus creating a favorable nutritional environment for intensive growth of Sweet Corn. In addition, among the CRF 3, 4 and 5g/plant treatment plots, CRF 5g/plant treatment showed the highest result in the av복불복룰렛사이트age fresh weight, total ear weight, width, length and diamet복불복룰렛사이트.
