Responses of Upland Rice cv Inpago LIPI Go4 to Microbial Inoculant and Nitrogen Fertilization Dosage Treatments

There is a huge potential of upland for developing food crops to shortage the increase in rice production in Indonesia. Upland rice that adaptable to dry land could support national rice production. Among the limit factors of upland rice productivity in Indonesia are infertile land and cultivation practices. The purpose of the study was to find out the effect of microbial inoculant application combined with nitrogen (N) fertilizer dosage to the cultivation of upland rice Inpago LIPI Go4. The factorial experimental design with two factors was applied, namely the supply of microbial inoculant and the dosage of N fertilizer and, i.e., 0%, 50%, 100% N (200 kg ha-1 Urea). The inoculant comprises of Aspergillus niger, Trichoderma viride, and Azotobacter. Each treatment combination was repeated four times. The microbial inoculant treatment solely effects significantly plant height, tiller number, and panicle weight of the upland rice, whereas N dosage treatment solely influences significantly plant height and tiller number. There was no interaction significant effect of microbial inoculant and N fertilizer dosage to all growth, production, and content of leaf N parameters. The maximum production of the upland rice was 4499 kg ha-1, whereas the average production was 3816 kg ha-1 grain weight. The highest yield was obtained from the plant with the supply of microbial inoculant and the treatment of 50% N fertilizer (100 kg ha-1 Urea).

Two Factors

Rice is the main product in Indonesia in the context of the supply of rice as a national food. Efforts to increase rice production are faced with various constraints such as fertilization ineffective and under-utilization of hybrid varieties by farmers. This study aims to determine the effect of differences in nutrient application through the leaves on the growth and yield of china’s hybrid rice. The method used is strip plots design. The design consists of two factors, namely the variety and diversity of nutrient factors. There are five varieties of rice that are used with 3 treatments a difference nutrient which is water, micro nutrient, complete nutrient. The results obtained indicate that the applications of micro-complete nutrient through the leaves have outcomes on the growth parameters that affect on plant height and the parameters of production that is the total number of grains per hill, weight of grain content per hill and percentage of grain content. Then, hybrid rice which has the highest potential yield after applying nutrient based on the amount of grain per clump is Hybrid I and Hybrid III.

Food Needs

Abstract Rice is the major food commodity in Indonesia and many other countries, as the main source of carbohydrate. Rice production must be increased continuously to meet food needs, one of which is by utilizing largely available dry land areas. Two important factors required to increase rice production on marginal soils are the use of high-production adaptive varieties and biological agents. It is necessary to conduct research on the application of local microbes to the cultivation of upland rice cultivars, with the aim to determine the best genotypes and/or suitable microbes. This research was carried out at the Research Field and laboratories of Faculty of Agriculture, University of Halu Oleo, from April 2020 to April 2021. The first tested factor was biological agents (local microbes), consisting of three levels, namely: without microbes (M0), the fungus Trichoderma sp. (M1), and the bacteria Pseudomonas sp. (M2). The second factor was the upland rice cultivar, which consisted of five levels, namely: V1 (Tinangge cultivar), V2 (Enggalaru cultivar), V3 (Bakala cultivar), V4 (Momea cultivar), and 1 nasional variety, namely V5 (Inpago-12 variety), as check variety. The research results showed that the interaction between local microbes Trichoderma sp. (M1) and Pseudomonas sp. (M2) on Tinangge (V1) and Momea (V4) cultivars gave a better effect on crop production. The best cultivar based on the growth and yield variables was generally obtained from the Momea cultivar (V4), although in many variables it was not significantly different from the Tinangge cultivar (V1). These cultivars could be further studied and possibly developed for promising cultivars in Kendari areas.

AbstractThe soil fertility and nutrient availability are limiting factors for growth and plant development. Fermented compost and nitrogen (N)-fertilizer are useful as sources of nutrients to support the growth of plant and microorganisms in soils. The combination of biological fertilizer and chemical fertilizer can support the concept of sustainable and integrated agriculture and minimize the adverse effects of chemical fertilizers. The research was conducted to get the recommended dose of fermented compost and N-fertilizer to increase the plant height and productivity of purple eggplant. The experiment was arranged as factorialized randomized block design and consisted of two factors and two replications, namely fermented compost dose (0, 5, 10, and 15 t ha−1) and N-fertilizer dose (0, 75, 150, and 225 kg ha−1). The observed responses were increase in plant height and productivity of purple eggplant. Compared to the control, the application of 15 t ha−1 fermented compost and 225 kg ha−1 N-fertilizer increased the plant height by 40.76% at 30 days after planting and 57.59% at 37 days after planting and increased the purple eggplant yield by 43.15%. BC ratio of the fermented compost (15 t ha−1) is 1.16 and BC ratio of the N-fertilizer (225 kg ha−1) is 1.09. Recommended dose to increase the plant height and productivity of purple eggplant in vertisol is 15 t ha−1 of fermented compost and 225 kg ha−1 of N-fertilizer.

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

Abstract Increasing rice production is not only relied on from irrigated and rainfed rice fields, but also on dry land (upland rice). Development of upland rice on sub-optimal lands is one of the efforts to overcome the problem of vulnerability to rice availability, but until now its management is still not optimal. Minahasa District is one of the upland rice producing districts in North Sulawesi. This paper aims to identify matters related to sub-optimal land use for the sustainability of upland rice farming by farmers that can be developed in support of efforts to increase upland rice production in North Sulawesi, in addition to improving the existing technology used by farmers. This study was conducted in the Tombariri Subdistrict, Minahasa District, using a survey method. Data collection was carried out through field observations, surveys, documentation, in-depth interviews with key informants, and literature studies. The data obtained were then analyzed descriptively. Based on field identification and the results of the study, it was found that the existing local farmers’ technology was still very simple, especially in the aspects of seed supply, planting and maintenance. Farmers are increasingly pursuing development towards organic farming. There are still many sub-optimal land uses that can be optimized for upland rice cultivation accompanied by improvements to the existing limiting factors on each land.

The need of rice as the staple food of the people of Indonesia has a deficit every year. Upland rice cultivation in dry land such as Ultisols became one of the alternatives to meeting the needs of rice. However, productivity of crop in Ultisols is low because of some problems of acidity and nutrients deficiency. It is necessary input such as ameliorants like biochar cocopeat of oil palm empty bunch compost (OPEBC) and the use of bacterial non-symbiotic nitrogen fixation (NSNF) to fix the problems. The research aims to study the effect of application of ameliorant and suspensions of bacterial isolates of NSNF on growth and N uptake by upland rice in Ultisols medium. The research was conducted at the Green House of the Faculty of Agriculture, University of Riau, Pekanbaru from Mei to September 2017. The research in form factorial experiment was arranged a completely randomized design (CRD). The first factor were ameliorant, consists of six type (biochar, cocopeat, OPEBC, biochar+cocopeat, biochar+OPEBC, each doses 50 g polybag-1 and without ameliorant as a control). The second factor were suspensions of bacterial isolates of NSNF, consists of three levels (10 and 20 ml polybag-1 and without bacterial isolates as a control). The parameters observed were plant height, number of tillers, weight of dry shoot and roots, N uptake by shoot and roots. The results show that the application of ameliorant (biochar, cocopeat, OPEBC, biochar + cocopeat, biochar + OPEBC), each doses of 50 g polybag-1 and suspensions of bacterial isolates of NSNF doses of 0, 10 and 20 ml polybag-1 increased plant height, number of tillers, weight of dry shoot and N uptake by shoot compared to control and the application of without ameliorant with suspension of bacterial isolates of NSNF doses of 0, 10 and 20 ml polybag-1.Key words : biochar, cocopeat, palm oil empty bunch, upland rice, ultisol
