Payo rice is one of the local rice varieties from Kerinci, Jambi Province. It is popular in Jambi due to its texture and good taste qualities. Farmer preferences changing to modern varieties and massive infrastructure development lead to Payo rice extinction. This research was aimed to find out the genetic diversity of Payo rice population-based on morphological markers in Kerinci area. Non-experimental research was conducted to obtain the data by direct survey or in situ characterization. Samples were determined using the proportionate stratified random sampling method. Morphological characters were measured both quantitatively and qualitatively based on IRRI and WARDA guidelines with few modifications. Quantitative data were analyzed using the coefficient of variability, while qualitative data were analyzed using relative diversity index (J). Genetic diversity among individual members of the population was analyzed using cluster analysis and presented in a dendrogram. Results indicated that several morphological characters, which were number of productive tillers, angle of flag leaf, threshability, number of empty grain, color of ligule, color of auricle, leaf surface, and color of grain, showed large variability, while others were narrow. Overall, relatively large genetic diversity was observed in Payo rice population in Kerinci area. At least 21 different genotypes were identified in the existing population.

Rice cultivation with a ratoon system is one of the efforts to increase rice production in tidal land. This study aims to determine the effect of harvest time and nitrogen fertilization of the main plant on the growth and yield of ratoon rice in tidal swampland. This study was conducted in the Experimental Field of Banyuasin District Agriculture Office in Tanjung Lago Regency. The design used in this study was the Split Plot Design which was repeated three times. The Main Plots: Fertilization N (N) consists of N1;½ dose at planting + ½ dose of primordia phase, N2; 1/3 dose at planting + 1/3 dose at primordial phase + 1/3 dose at harvest, and N3; 1/3 dose at planting + 1/3 dose at primordia phase+ 1/6 dose at harvest +1/6 dose at 21 days after harvest.Plot: Harvest time (W) consists of W1; the main crop is harvested 5 days before 100% ripening, W2; main crop is harvested when 100% ripening, and W3; the main crop is harvested 5 days after 100% ripening. The results showed that the harvest time and N fertilizer of the main plants affected the growth and yield of ratoon rice in tidal land. Treatment of harvest time 5 days before 100% ripening and N fertilization has given 1/3 dose at planting + 1/3 dose of primordia phase +1/3 dose at harvest, tended to show higher growth and yields of ratoon rice than other treatments, that is 2.06 tons/ha or 54.2 percent compared to the main crop.

Soybeans are rich in protein and very appreciated by the public of Indonesia. However, soybeans decreased productivity and improved through the expansion of planting areas such as shallow swampy wetlands and the use of biofertilizers such as phosphate solubilizing bacteria (PSB), Azospirillum, mycorrhiza, and bio-organic fertilizer. The results of previous studies have shown that biofertilizer can increase rice productivity in lowland and tidal land. Furthermore, the biofertilizer can assist in providing the uptake of N and P and improve soybean productivity in the lowland area. Field research in shallow swampy areas in Ogan Ilir, South Sumatra Province. Random Group prepared five treatments with five replications. The treatments include biofertilizers, PSB, mycorrhiza, Azospirillum, and BOF. The results showed that the PSB, mycorrhiza, Azospirillum, and BOF can increase N nutrient absorption in a row 201.33%, 182.67%, 170.67%, 161.33%, P nutrients 357.89%, 273.68%, 173,68%, 142,40%, soybean production respectively 228.00%, 208.00%, 201.33%, and 194.67% compared without biofertilizer

Rice is one of the main sources of carbohydrates for Indonesian society. The development of new varieties depends on the availability of germplasm as the source genetic material. The development of new varieties can be done through artificial crosses (local cultivars and superior lines) for the creation of diversities. The research aimed to explore the genetics parameters from eight rice characters, for the selection program. The crossing was conducted by using four local cultivars and one pure line with diverse agronomic characters. Four hybrids (F1) were planted using completely randomized design with four replications, and five parental as the check varieties (landrace and pure line). The correlation coefficient was found that there was one character showed strong correlation almost all the character that is panicle weight. While high heritability was found in harvest age, panicle length, number of grain per panicle, 1000 grain weight, and plant high. Hybrids that showed negative heterosis for harvest age are from B14081H-296 x Salak and Dampak x Carogol, which have shorter harvest age compared to the average of the parental plant which is dominant gene action and additive.

The brown planthopper (BPH)-resistant rice, early maturity, and aromatic are expected by both farmers and consumers. The traits have been combined through gene pyramiding and some promising rice genotypes obtained. However the genetic control of BPH resistance and maturity is quantitatively inherited, it is therefore both molecular and phenotypic assessments would be tremendously helpful in selecting promising genotypes. The study aimed to obtain genotypes with such valuable traits. Rice lines were analyzed using molecular markers i.e., RM586, RM589, RM8213 (BPH resistant gene markers); RM7610 and RM19414 (early maturity markers), and IFAP (Internal Fragrant Antisense Primer) for detecting aromatic, and INSP (Internal Non-fragrant Sense Primer) for non-aromatic rice. Phenotypic assessment was performed for brown planthopper resistant-related traits, such as chlorophyll content, stomatal conductance, and trichome density. Other evaluations were heading date and aroma (using 1.7% KOH solution). Results showed that molecular markers for evaluating BPH resistance genes (Bph3, Bph4, Qbph4, and Bph17), aroma (fgr gene), and heading date (Hd2 and Hd3 genes) could differentiate genotypes, and they serve as perfect markers, except for heading date markers. Seven genotypes i.e., #2, #3, #4, #5, #6, #10, and #11 were related to all traits expected based on molecular marker analysis. Meanwhile, genotypes #1, #2, #4, #6, and #11 were similar to their parents based on phenotypic analysis. Pyramiding program based on molecular and phenotypic markers enables us to combine three valuable traits into one rice genotype as presented in this study

Post tin mining land is one of marginal land because it has low nutrient availability. Efforts to utilize post tin mining land in agriculture for crop cultivation such as sorghum by application various doses of chiken manure an N,P,K. The purpose of this study was to determine the response of sorghum growth and production in post tin mining land by application various doses of chicken manure and N,P,K. This research used a factorial randomized block design with 6 treatment combinations and 4 groups. The first factor was the dose of chicken manure consisting of 100%, 50%, and 25% the reference dose. The second factor was the dose of fertilizer N, P, K which consists of 100% and 50% the reference dose. The results showed that chicken manure significantly affected leaves number parameters. Fertilizer N, P, K gave very significant effect on plant height, stem diameter, wet stover weight, root length, seed yield per plant and productivity. Fertilizers N, P, K significantly affect the total parameters of dissolved solids. The reduction of the dose of chicken manure from 100% to 50% showed no significant difference on leaves number. Reduction of N, P, K fertilizer doses showed significantly different results on all parameters. The A1K1 treatment (100% chicken manure + 100% N,P,K) is the best combination of treatment for the growth and production of sorghum in post tin mining land.

The germination period is a critical phase of abiotic stress, including salinity stress. Invigoration can be done to reduce the effect of salinity stress and speed up the germination process. This research was aimed to find out the effect of invigoration to mitigate salinity stress of soybean seed germination. This research was conducted in the Greenhouse of Faculty of Agriculture, Siliwangi University. The experiment was arranged in a randomized block design with factorial patterns and three replications. First factor was the level of salinity of seawater, consisted of 3 levels ( 0% = EC= 0,6 mS cm-1; 10% =EC = 7,69 mS cm-1 ;and 20% = EC =11,4 mS cm-1). The second factor was invigoration, which consisted of 4 levels (water as control, mangosteen peel extract, turmeric extract, and mixture of mangosteen peel extract + turmeric extract with a ratio of 1:1). Results showed that there was no interaction effect between the invigoration and salinity stress on all parameters observed, but there was an independent effect of invigoration on soybean vigor and salinity stress. The salinity stress had a significant negative effect on seed germination. The invigoration of mangosteen peel extract or turmeric extract was able to maintain soybean seed vigor under salinity stress conditions. Therefore the invigoration could mitigate the effect of salinity stress of soybean seed germination.

Barangan banana (Musa acuminata L.) is a plant that has the biggest contribution to national fruit production. The increasing demand for the banana requires the availability of seedlings, while conventional cultivation is unable to produce healthy, disease-free seedlings in a short time and large amount. In vitro culture is considered to be able to handle the constraints of the conventional seed supply. The purpose of this study was to determine the effect of foliar fertilizers on in vitro multiplication of barangan bananas. The method used was a single factor of Completely Randomized Design (CRD), the addition of leaf fertilizer consisting of five levels of media treatment, media MS (control), and 0.50 ml L-1 (p1); 0.75 ml L-1 (p2); 1.00 ml L-1 (p3); 1.25 ml L-1 (p4); 1.50 ml L-1 (p5) of leaf fertilizer media repeated five times. The data were analyzed with Analysis Variance then followed by Duncan Multiple Ranged Test of 5%. The results showed MS media still gave the best results compared to other leaf fertilizer media. Meanwhile, the leaf fertilizer media used in this study still gave good results on the initial time of buds appearance (p3 treatment), the number of shoots and the number of leaves in the p5 treatment, as well as the height of the plant in the p4 and p5 treatments. Therefore, the leaf fertilizer can be used to substitute MS media

The improvement of low nitrogen tolerant hybrid maize face on genotype x environment the genotype x environment interaction caused a genotype unable to maintain its appearance under suboptimal conditions. it caused the breeders difficult to choose varieties that are stable at optimal and suboptimal conditions. The using of simultaneous stability analysis methods can provide more authentic stability information. This study aims to 1) determine the yield stability of the promising low N tolerance hybrid maize varieties, 2) to obtain varieties that have high yield and stability and under optimal and sub-optimal conditions. This research was conducted at Bajeng Experimental farm, Gowa, South Sulawesi. The research was arranged in a split-plot design with two replications. Three levels of fertilizer N (N0 = 0 kg N ha-1, N1 = 100 kg N ha-1 and N2 = 200 kg N ha-1) as the main plot and 39 genotypes of maize (36 hybrids resulting from crosses of low N and 3 checks varieties Nasa 29, Bisi 18 and Jakorin 1) as the subplot. The variable measured was grain yield. The yield stability analyses were performed by Francis and Kannenberg, Finlay and Wilkinson, Eberhart and Russel, and GGE Biplot methods. The results showed that there were no genotypes stable in overall the four methods, but three genotypes considered as stable genotype based on two methods. H5, H6 and H15 genotype were the genotypes with high stability and high yield. The three genotypes had the opportunity to be released as a low Nitrogen tolerant maize hybrid.

Foxtail millet has the potential to be developed as a healthier food alternative because of its high nutritional value. Disease such as leaf blight caused by Bipolaris setariae is one of the limiting factors in Foxtail millet productivity. One of the efforts to control the pathogen is by utilizing resistant varieties. In this study, two candidate varieties and two germplasm accessions were tested to determine the level of resistance to Bipolaris setariae leaf blight. The study was arranged based on a complete randomized design with six replications. Each test material was inoculated with the spore suspension at 4 WAP. Disease intensity was observed based on the disease scoring at 7, 9, and 11 WAP. AUDPC value is calculated based on the intensity of the attack at a particular observation time. Grain weight was recorded and statistically analyzed. The two candidate varieties of foxtail millet Pagamogo and Tedamude from Nagekeo Regency showed a moderately resistant response to leaf blight and had the lowest AUDPC values of 907.69 and 912.31. The highest increase in AUDPC values was observed in the initial observation period at 0-49 DAP.
