Increasing The Growth and Yield of Lowland Rice (Oryza Sativa L.) with Optimum Dosage and Frequency of Potassium

Abstract

Lowland rice is a commodity crop that is very influential in the survival of many people, especially inhabitants in most Asian countries, especially Indonesia. Rice is the staple food of Indonesian people, the shortage of which can result in complications for the country. In connection with this food security issue, it is necessary to make efforts to prevent food shortages. The national production capacity of rice must be increased. The long-term goal is to increase the productivity of rice plants to support Indonesia towards rice self-sufficiency. This study has a short-term objective, namely, to determine the effect of potassium fertilizer and to obtain the best dose on the growth and production of rice plants. This was a factorial experiment using a completely randomized design (CRD) with two factors: the KCl fertilizer dosage and the frequency of fertilizer application. The results showed that the best treatment was with a potassium fertilizer dosage of 150 kg ha-1 with a frequency of 2-time fertilizer application.

Synergic Effects of Salinity and Rhizoctonia solani (Kuhn) Infection on Growth and Yield Attributes of Rice (Oryza sativa L.)

“…Despite the economic importance of this crop, the cultivation of rice encounters a multitude of challenges, encompassing both abiotic and biotic stresses. Salinity stress and the infection caused by the fungus Rhizoctonia solani are particularly damaging and harmful, leading to substantial and noteworthy reductions in crop productivity and posing a grave and significant threat to food security in regions that heavily rely on rice products (Effendi et al, 2023;Senguttuvel et al, 2023). In order to address and surmount these challenges, effective strategies are imperative to mitigate their impact and ensure the sustainable and enduring production of rice.…”
