However, statistically similar grain yield (9887 kgha-1) was also obtained under application of 92 kilo gram nitrogen per hectare in the same intra spacing (20 cm). Key Message: Chitosan foliar application enhances yield with booting thermos-tolerance ability by improving enzymatic and non-enzymatic antioxidant systems in cucumber genotypes under high temperature. N, particularly for 0.010 % treated plants, both in maize and soybean. Although goldenrod (Solidago canadensis) is considered an invasive plant in many countries, it is a global cut-flower species. that by using the nano-chitosan as a foliar spray on mango trees with concentration of 5 mL LG1 to improve the vegetative growth and fruit quality. Some recent hybrids have erected and narrow leaf nature so that providing space for growing additional crop stands to increase yield per unit area. Foliar spray of chitosan alleviates cadmium stress and improves G s, C i, P N and Tr in Brassica rapa (Zong et al., 2017). Results also showed that application of chitosan as a bio-elicitor can reduce the adverse effects of water deficit stress on marjoram plant. The characteristics of nitrate reduction exhibited by the tropical leguminous tree Erythrina senegalensis differ in several respects from those of other higher plants. The chitosan was sprayed three times at 25, 40 and 55 days after sowing. N of soybean plants did not differ from the control plants except for treatment CH5 (10–7 M) which caused an 8 % increase on day 2, along with increased g Origanum is one of the most important medicinal plants used worldwide due to the economic importance, quantity and quality of essential oil and antioxidant properties. Chitosan not only provides an antimicrobial film that prevents mold growth [4], it causes a reaction that also improves the immune system of plants. It was revealed that yield per plant was highest in L3466 (2.12 kg) and Desi-cucumber (2.10 kg) with chitosan application on the 1 st sowing date, while yield per plant was reduced in Suyo Long (0.31 kg) and Poinsett (0.29 kg) on the third sowing date with chitosan application. Chitosan improved the enzymatic antioxidants and osmolytes in enhancing the ability of cucumber to tolerate heat stress. relative growth rate; Pn: photosynthesis; NR: nitrate reductase, home garden vegetable and a good source to fulfill the energy. The effects of 0.1% and 0.5% chitosan application on the shoot growth of rice and soybeans were investigated after incorporating it into soil before planting. N) of soybean and maize, however, on subsequent days there was an increase in P The application of the techniques mentioned above can be facilitated by combining it with the use of chitosan-polyacrylic acid (CS-PAA) complexes, CS hydrogels, and of CS-polyvinyl alcohol hydrogels (CS-PVA). Key words: Nano particles, chitosan, malformation, Mangifera indica, vegetative growth, ball mill The dry matter content was higher in plant treated with application of chitosan @ 90mg/1000ml (31.03%) as compared to other chitosan application, while 83729-1 UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. 20460 OFFICE OF CHEMICAL SAFETY AND POLUTION PREVENTION/OFFICE OF PESTICIDE PROGRAMS DATE: 5/19/ 2011 SUBJECT: Science review of efficacy data for label amendment of … s) and transpiration rate (E), while the intercellular CO2 concentration (C All the investigated parameters were unaffected with increasing concentrations from 100 to 200 ppm and frequencies of applications from twice to thrice.
