Chinese Kale yield increased by application of Nousbo Controlled Release 스포츠 토토 사이트 in Thailand. Research summary

(Summary of the study of Nousbo 스포츠 토토 사이트 26-5-12 effect on Chinese Kale growth and yield performances in Thailand)

With the increasing public concern about human health, environmental protection and sustainability of natural resources, it is essential to develop environmentally friendly 스포츠 토토 사이트s. CRFs are a good alternative to soluble 스포츠 토토 사이트 in order to increase nitrogen usage efficiency and minimize nutrient losses in the field environment. Therefore, CRF 26-5-12 was evaluated for its efficacy as one-time application product for complete nutrient supply for Chinese Kale from August to January, 2018-2019 in two locations in Thailand: King Mongut’s Institute of Technology Ladkrabang (KMITL) field in Bangkok, which is considered as field with low soil fertility, and Chiang Mai University field in Chiang Mai Province, which is considered as field with common soil fertility.

Nousbo CRF 26-5-12 is a 스포츠 토토 사이트 in the form of granules coated with polymer material that can control the rate, pattern and duration of plant nutrient release. For both two locations, the CRF efficiency was evaluated at the rate of 2, 3 and 4 g/plant as a single base 스포츠 토토 사이트 which is equal to 320 kg/ha, 480 kg/ha and 640 kg/ha respectively, and compared with conventional 스포츠 토토 사이트 at the rate of 320 kg/ha applied 3 times as top dressing, which equals to 960 kg/ha in total. Data for growth and development was recorded by assessment of the leaf length, leaf weight and yield at harvest. SPAD (soil plant analysis development) chlorophyll meter reading (SCMR) was also recorded. Results are summarized in the following table.

Analysis of growth parameters of Chinese kale showed that fresh weight at harvesting state was higher in all CRFs treated plots compared with conventional 스포츠 토토 사이트-treated plots. Total fresh weight values in KMITL were 28.51, 38.18 and 40.24 g/plant for 2, 3 and 4 g/plant CRF treatments, respectively, while the total fresh weight of Chinese kale plants treated with conventional 스포츠 토토 사이트 was only 27.57 g/plant. The result from Chiang Mai field experiment revealed that the enhanced fresh weight of Chinese kale was recorded for CRF 2, 3 and 4 g/plant treatments. It was also observed, that a significantly higher chlorophyll index can be obtained in all CRF 스포츠 토토 사이트 treated plots. Similar trends of treatment effects on other Chinese kale yield parameters such as leaf weight and leaf length were recorded as well.

[ Yield quality of Chinese kale affected by various kinds of 스포츠 토토 사이트s ]

The experiment results indicated that single basal application of CRF obviously contributed to a greater supply of soil available nutrient, thus creating a suitable nutritional environment for vigorous growth of Chinese kale, even though all CRF rates used in this experiment contained available N-P-K lower than conventional 스포츠 토토 사이트. In addition, among the CRF 2, 3 and 4 g/plant treatments, CRF 4 g/plant treatment showed the best effect on the average fresh weigh of Chinese kale.
