Saleem M., . and Mohd Khanif Yusop, . and Hafeez B., . and Samsuri A.W., . and Radziah O., . (2008) Micronutrient status of some rice genotypes of Malaysia. [Proceedings Paper]
Abstract
Availability of micronutrients in seeds plays a very important role in plant growth and crop production. Healthy plant seedlings depend upon mineral contents in the seeds for its development at germination and early growth stage. Micronutrient deficiency in rice especially zinc may depress 50 of rice yield without producing any symptoms in the field. It is very difficult to overcome the deficiency problem only on the basis of symptoms. Thus deficiencies or toxicities should always be confirmed by chemical analysis. Keeping this fact in view thirty-one rice genotypes were collected for the determination of their micronutrients status with paddy and rice paddy without husk. Data for paddy indicates that the 18 out of 31 genotypes were found to be low in zinc concentration 20 ug g -1. The highest zinc concentration was observed for genotype Kadaria 26.93 ug g -1 and the lowest concentration was noted for Seri Malaysia Dua genotype 15.40 ug g -1. Whereas in rice all genotypes were found to be below the critical limit. More over in both paddy and rice the micronutrients Mn Fe and Cu were found to be below their critical limits of 50 250 and 10 ug g -1 respectively for all genotypes. Results also revealed that 58.06 of investigated genotypes were observed to be low in zinc concentration in paddy for all genotypes. This was also found to be true for rice.
