“…Similar result was reported by Ferdous et al (2018). Increased effective tiller production of NPKSZn compared to the recommended NP and NPK can be attributed to the ability of Zn to increase N use efficiency and Zn induced enzymatic activity as well as auxin metabolism in plants (Arif et al, 2018;Rana and Kashif, 2014). Number of effective tillers was also significantly different among the rice varieties.…”

Field experiment was conducted on Nitisols to evaluate the effects of combined application of primary, secondary and micronutrients on grain yield and protein content of upland rice varieties compared to the national recommendation. Factorial combination of five nutrient combinations (control, NP, NPK, NPKSZn and NPKSCaZn) and three upland rice varieties (Nechu Eruze, Superica-1 and NERICA-4) were laid out in a randomized complete block design with three replications. The result revealed that nutrient combinations significantly affected plant height and number of effective tillers m-2. The highest grain number per panicles of 122 and 1000 grain weights of 30.9 g were recorded from NPKSZn. The maximum grain yield (4055.6 kg ha-1) was also obtained from NPKSZn, followed by NPKSCaZn. Moreover, maximum grain protein content was registered from NPKSZn and NPKSCaZn. In contrast, the lowest value of these parameters was scored from the control. Among the varieties, NERICA-4 performed better than both varieties in yield and yield components. However, grain protein content of rice varieties was statistically similar. Overall, combined application of primary, secondary and micronutrients significantly improved grain yield and protein content of upland rice compared to nationally recommended NP combinations.

“…Production of rice (Oryza sativa) currently depends heavily on the application of chemical fertilisers for plant growth (Arif et al 2018) and pesticides for pest control (Rahaman et al 2018). However, the injudicious use of these chemicals has raised public concern about farmers' health and also pollution in the rice ecosystem (Pingali & Roger 1995).…”

Comparison of aqueous seasoning cube solution and nutrient broth as culture media for production of the biocontrol agent <i>Bacillus megaterium </i>in the laboratory, and for suppression of rice grain discolouration in the field

Bacillus megaterium is a beneficial bacterium that is used as a biological control agent (BCA) against the fungi Rhizoctonia solani, Fusarium sacchari and Curvularia lunata, which attack rice plants. However, the cost of preparing the bacterium using standard nutrient broth is prohibitively expensive on a large scale. Therefore, a low-cost product (seasoning cube, a common ingredient for cooking) was examined as an alternative nutrient medium. Bacillus megaterium was cultured in either nutrient broth or in dissolved seasoning cube. These cultures were evaluated for their effect on the growth of rice seedlings in the laboratory and to suppress grain discoloration of rice in small-scale field trials. Bacillus megaterium cultured with a seasoning cube was as effective as standard nutrient broth for the growth of rice seedlings in the laboratory. It also suppressed grain discoloration disease of rice in small-scale field trials. Use of a seasoning cube is suitable for culturing B. megaterium and should be recommended to farmers.
