“…The effort to increase the productivity of other rice plants is to fulfill their daily needs [22]. Fertilization aims to increase the nutrients needed by plants because nutrients contained in the soil are not always sufficient to optimally promote plant growth [23]- [26]. So far, farmers tend to use inorganic fertilizers continuously.…”

Rice is an important food crop in Indonesia. This condition encourages the need to increase national rice production. Increased national rice productivity is also needed to reduce rice imports and achieve resilience and self-sufficiency. The effort to increase national rice production is Salibu rice cultivation. This study uses a split- split plot design with an area plot of 1m x 1m, whereas the main plot is the organic rice booster formula from the stem trimmed 15 cm (B) and the stem trimmed 30 cm (N). Organic cow manure (B1), organic goat manure (B2), chicken organic manure (B3) and not given (NB) as subplots while three rice varieties, Ciherang, Mekongga and Inpara as subplots.. The parameters observed for the potential of each production variety in each plot of all treatments (ton/ha) included the number and weight of grain and rice growth including plant height, panicle length, and some tillers. From the results of preliminary research that the weight production of plotted grain has a very significant effect on the V2 Cavity Variety (213.46). For V3 Veritas V3 has a genuine effect on V2 Vascularity. Parameters of Grain Weight Perplot after statistical tests showed that the treatment of Chiherang V1 variety (870.63 gr) had no significant effect on Variety V3 (872.08 gr), but it was the very significant effect on Void Cavity V2 (901.63 g). For V3, it has a genuine effect on V2 Vascularity.

“…Organic and inorganic fertilizers as well as fungicides and pesticides, are being increasingly used to boost productivity and stress tolerance of rice crop (Gribaldi et al 2017 ; Muhammad et al 2019 ; Iqbal et al 2020 ; Zhang et al 2020 ). However, besides being costly the application of these chemicals reduces the quality of soil and causes environmental pollution.…”

The influence of endophytes on rice fitness under environmental stresses

Key Message Endophytes are crucial for the promotion of rice growth and stress tolerance and can be used to increase rice crop yield. Endophytes can thus be exploited in biotechnology and genetic engineering as eco-friendly and cost-effective means for the development of high-yielding and stress-tolerant rice plants. Abstract Rice (Oryza sativa) crop is continuously subjected to biotic and abiotic stresses, compromising growth and consequently yield. The situation is exacerbated by climate change impacting on ecosystems and biodiversity. Genetic engineering has been used to develop stress-tolerant rice, alongside physical and chemical methods to mitigate the effect of these stresses. However, the success of these strategies has been hindered by short-lived field success and public concern on adverse effects associated. The limited success in the field of stress-tolerant cultivars developed through breeding or transgenic approaches is due to the complex nature of stress tolerance as well as to the resistance breakdown caused by accelerated evolution of pathogens. It is therefore necessary to develop novel and acceptable strategies to enhance rice stress tolerance and durable resistance and consequently improve yield. In the last decade, plant growth promoting (PGP) microbes, especially endophytes, have drawn the attention of agricultural scientists worldwide, due to their ability to mitigate environmental stresses in crops, without causing adverse effects. Increasing evidence indicates that endophytes effectively confer fitness benefits also to rice under biotic and abiotic stress conditions. Endophyte-produced metabolites can control the expression of stress-responsive genes and improve the physiological performance and growth of rice plants. This review highlights the current evidence available for PGP microbe-promoted tolerance of rice to abiotic stresses such as salinity and drought and to biotic ones, with special emphasis on endophytes. Associated molecular mechanisms are illustrated, and prospects for sustainable rice production also in the light of the impending climate change, discussed.

“…Farmers usually utilize tidal lowland for rice cultivation at B and C flooding types land. Tidal lowland has several constraints consisting of continuous price increase of production facilities, lack of manpower and planting period that is highly depend on seasonal condition, low rice production due to high acidity of soil and relatively low availability of nutrients [3,4,5] as well as water flooding at some flooding-types of land [6]. Therefore, it is expected that those constraints can be overcome by using rice cultivation with ratoon system through proper fertilizer application and the use of adaptive rice varieties at several land flooding types.…”

Aims: This research objective was to determine productivity of two rice varieties using ratoon system through regulation of N fertilizer application at two flooding types in tidal lowland area. Place and Duration of Study: The study was conducted from February to July 2020 at two locations in tidal lowland area, i.e. B-type flooding located at -203859, 132S 10404428,449E and C-type flooding located at -203858,81S 10404426,745E in Mura Sugih Village, Tanjung Lago Subdistrict, Banyuasin District, South Sumatra, Indonesia. Study Design: The experimental design used in this study was Factorial Randomized Block Design with two treatments factors and four replications. The variety treatments (V) were consisted of V1: Inpari 30 and V2: Hipa 5 Ceva. N fertilizer application treatments (A) were consisted of A1: N fertilizing: 1/3 dose at planting period + 1/3 dose at 42 dap + 1/3 dose at 1 day after harvest (dah) of main crop; A2: N fertilizing: 1/3 dose at planting period + 1/3 dose at 42 dap + 1/6 dose at 1 dah of main crop + 1/6 dose at 21 dah of main crop. Result: The results showed that N fertilizer application regulation can increase productivity of two rice varieties using ratoon system at two flooding types land in tidal lowland area. Productivity of rice hybrid (Hipa 5 ceva) tend to be higher than that of rice inbred (Inpari 30) using ratoon system at two flooding types land in tidal lowland area. Productivity of two rice varieties using ratoon system tend to be higher at B-flooding type land than that of C- flooding type land.
