Effect of Organic and Inorganic Fertilizer on the Growth and Yield Components of Traditional and Improved Rice (Oryza sativa L.) Genotypes in Malaysia

Rice is the most important staple cereal human nutrition and consumed by 75% of global population. plants need a supply essential nutrients for their optimal growth. production has increased tremendously in Malaysia insensitive irrigation use inorganic fertilizers pesticides. However, effect using resulted contamination ground water decreased productivity soil, which turn affected rice long term. The organic manure may help to regain soil health, but that insufficient providing achieve Therefore, combined with applied obtain optimum yields. This study aims test on growth yield components 65 genotypes. pot experiment was conducted at net house field 10, University Putra Malaysia, UPM, during period February June 2019 August December randomized complete block design (RCBD) three replications. There were treatment combinations viz. T1: 5 t ha?1 chicken (CM), T2: 2.5 CM + 50% CFRR, T3: 100% (150 N: 60 P2O5: K2O kg ha?1) chemical fertilizer recommended rate (CFRR). Grain straw samples collected analysis, physical parameters measured harvest stage. Results showed significantly influenced due application fertilizer. alone or combination significant increase growth, component traits, nutrient content (N, P, K) all Treatment CFRR as well better performance than other treatments. It observed genotypes can be substantially judicious benefits mixed fertilization (organic inorganic) not only crop yields also promotion reduction input, etc.
