“…The experimental plots were kept at a distance of 2 feet from each other. There were 30 experimental units, and each unit consisted of six plants, i.e., a total of 180 plants [37]. Rice seeds were treated as follows: F0 = control; F1 = treatment with 0.5% leaves extract + PGPR; F2 = treatment with 1% extracts + PGPR; F3 = treatment with 1.5% leaves extracts + PGPR; F4 = treatment with 2% leaves extracts + PGPR.…”

“…The temperature of the injector and detector was 230 and 250 • C, respectively. The mass spectra generated from this analysis were compared with the mass spectra of standard compounds available in the mass spectra library of the National Institute of Standards and Technology (NIST), USA [37]. The peaks of the spectra were initially identified based on their matching of relative retention time (RT) with respect to the standard sample.…”

Rice is a crop that is consumed as a staple food by the majority of the people in the world and therefore failure in rice crops, due to any reason, poses a severe threat of starvation. Rice blast, caused by a fungus Pyricularia oryzae, has been ranked among the most threatening plant diseases of rice and it is found wherever rice is grown. All of the rice blast disease management strategies employed so far have had limited success and rice blast has never been eliminated from rice fields. Hence, there is a need to look for the best remedy in terms of effectiveness, sustainability, and organic nature of the method. This study was aimed at determining the plant growth-promoting and fungicidal effects of a mixture of Piper caninum and Piper betle var. Nigra leaves extracts and rhizobacteria. Gas chromatography–mass spectrophotometry (GC-MS) analysis of a mixture of leaves extracts of these plants revealed the presence of new bioactive compounds such as alpha.-gurjunene, gamma.-terpinene, and ethyl 5-formyl 3-(2-ethoxycarbonyl) in a mixture of leaves extracts of P. caninum and P. betle var. Nigra. The mixture of these extracts reduced the intensity of blast disease, inhibited P. oryzae, and improved the growth, yield, and quality of Bali rice. All treatments comprising of different concentrations of a mixture of leaves extracts of P. caninum and P. betle var. Nigra plus rhizobacteria exhibited biocontrol and bioefficacy. However, a 2% concentration of a mixture of these leaves extracts with plant growth-promoting rhizobacteria (PGPR) exhibited potent inhibition of growth of P. oryzae, a significant reduction in the intensity of blast disease, and a maximum increase in growth, yield, and quality of Bali rice. In the 15th week, the intensity of blast disease decreased from 80.18% to 7.90%. The mixture of leaves extract + PGPR also improved the height of the plant, the number of tillers, number of leaves, number of grains per panicle, number of heads per panicle, and the full-grain weight per clump. Applications of various concentrations of a mixture of leaves extracts + PGPR resulted in improvement in the potential yield of rice, however, the application of 2% extracts + PGPR gave the highest potential yield of 5.61 tha−1 compared to the low yields in the control and other treatments. The high grain yield observed with the treatment was caused by the low intensity of blast disease. This treatment also strengthened the stem and prevented the drooping of the plant and improved the quality of rice grain.

To produce quality rice, improvement in rice production management must begin at the farmer level (on-farm) by using high-quality seeds and good plant maintenance. Good quality rice is rice grains that don't break or crumble. To urge good quality rice, rice producers usually sort it manually. This method leads to long work processes and low productivity. Efforts to beat this problem are by designing a rice sorting machine which will separate whole rice and broken rice so on lighten the workload, improve rice quality, and increase prices. The results of the study obtained that the look specifications of the rice sieving machine were a). The sieving capacity is 10 kg of rice, the most drive is an electrical motor of 0.25 HP, a V-belt transmission, and an angled iron frame. Machine dimensions: length 120 cm, width 70 cm and height 90 cm). Machine testing the standard of rice grains employing a sorting machine can improve the standard of rice grains by reducing the presence of broken rice (size p=0.30 mm and below) a mean of 0.2 kg for 10 kg of sorted rice or increasing the standard by 1.91%. Machine testing from the ergonomic aspect.

Under the guise of enhancing productivity, using pesticides and artificial fertilizers in agriculture affects both the environment and living things. High chemical residues in food and the environment disrupt the health of consumers. One of the solutions that can bring about a reduction in the use of pesticides and chemicals is switching to organic fertilizers. The application of biopesticides originating from biological sources such as plant extracts and the use of microbes is gaining global acceptance. Therefore, this study aimed to obtain the best biopesticides and biostimulants that could suppress the leaf spot pathogen, Nigrospora oryzae, and increase the growth and yield of Bali red rice. The study contained four treatments, namely untreated control (F0), Piper caninum leaf extract (F1), Brevibacillus agri (F2), and fermented P. caninum leaf extract plus B. agri (F3). The treatments were arranged in a randomized complete block design, and each treatment was replicated three times. The parameters measured were the number of tillers per plant, number of leafs per plant, chlorophyll content, number of grains per panicle, grain weight, and grain yield. Furthermore, antimicrobial and antioxidants were assayed using SEM. GC-MS. At the end of the experiment, the disease index of the leaf spot was measured. The results showed that F3 significantly suppressed leaf spots caused by N. oryzae compared to other treatments, including untreated control in red rice. Additionally, the F3 significantly increased the number of productive tillers, number of grains per panicle, and grain yield compared to all other treatments. The F3 enhanced the crop yield at 6.19 tons/ha, an increase of 50% compared to the untreated control. The SEM.GC-MS results showed the presence of 2.3 butanediol, tetra-decanoic acid, butanoic acid, ethyl ester, benzene propanal, 3-(1,1-dimethylethyl)-a-methyl, a-N-Normethadol in treated plants with P. canicum plus B. agri.
