  Background and Objective: Rice (Oryza sativa L.) is a very important food crop in Indonesia. The development of upland rice becomes an alternative solution to meet the national rice needs. Upland rice productivity is lower than wetland rice, one of the causes is the use of low-vigor seeds. The seeds derived from previous harvest seed and newly harvested rice seedlings have physiological dormancy. Physiological dormancy relates to seed persistency. The study aimed to evaluate the persistence and development of invigoration technique to break seed dormancy of upland rice. Materials and Methods: The research was conducted at the Agronomy Laboratory, Faculty of Agriculture, Halu Oleo University. Research was arranged in a completely randomized design (CRD) consisting of 6 treatments namely: A0 (without treatment), A1 (KNO3 1%), A2 (ground brick matri-conditioning+Bacillus sp., CKD061), A3 (ground burned-rice husk matri-conditioning+Bacillus sp., CKD061), A4 (ground brick matri-conditioning+Bacillus sp., CKD061+KNO3 1%) and A5 (ground burned-rice husk matri-conditioning+Bacillus sp., CKD061+KNO3 1%). Results: The results showed that upland rice cultivars from Southeast Sulawesi have varying dormancy. The persistence of seed dormancy evaluated are Pae Parigi 2 is 8 weeks, Pae Parigi 1 is 9 weeks, Pae Kulibungka is 10 weeks, Pae Masaraha is 12 weeks and Pae Rowu is 16 weeks. Conclusion: Application of seed bio-invigoration treatment was able to break seed dormancy of local upland rice of cv. Pae Parigi 2 with the best treatment was using KNO3 1%+ground brick+Bacillus sp., CKD061.

  Background and Objective: Every plant needs a suitable growing medium to grow and develop optimally. The growing media provide nutrients and an ideal place for roots to grow and take nutrients. This study aimed to obtain a suitable growing medium composition to increase the growth of areca nut. Materials and Methods: The research was carried out at the Agronomy Laboratory, Faculty of Agriculture, Halu Oleo University, Indonesia from March-September, 2020. Nine treatments of growing media composition in combination with the percentage of soil medium, rice husk charcoal and organic fertilizer used and arranged in a Randomized Block Design (RBD) with three replications. Results: The result showed that the composition of the growing medium has a significant effect on the growth of areca nuts. Growing media using the composition of 25% soil, 25% rice husk charcoal, 50% of organic plus fertilizer (M5) is the best growing medium composition that can increase the growth of areca nut. Another growing media is composed of 50% soil, 0% rice husk charcoal, 50% organic plus fertilizer (M2), 50% soil, 50% rice husk charcoal, 25% organic plus fertilizer (M4), 25% soil, 50% rice husk charcoal, 25% organic plus fertilizer (M7) and 0% soil, 50% rice husk charcoal, 50% organic plus fertilizer (M8) can also be an alternative in increasing the growth of areca nut. Conclusion: The composition of the growing medium has a significant effect on the growth of areca nuts seedling. The growing media using the composition of 25% soil, 25% rice husk charcoal and 50% organic plus fertilizer is the best growing medium composition that can increase the growth of areca nut seedling.

  Background and Objective: The use of cover crop residue for improving soil quality has been widely applied. Nevertheless, the effectiveness for improving ex-mining soil quality and crop performance at ex-mining soils is rarely documented. This study investigated the effect of cover crop residue on soil quality enhancement and corn production established in ex-nickel mining soils. Materials and Methods: An experiment comprising three treatment of cover crops residue, including Eleusine indica, Centrosema pubescens and Calopogonium mucunoides, arranged in a completely randomized design with three replications. The soil improvement process was evaluated by several parameters, such as soil acidity, soil organic carbon, total nitrogen, exchangeable potassium, exchangeable magnesium and heavy metals. On the other side, corn's growth performance was assessed using some attributes, i.e. height, diameter, total leaves, leaf area and biomass accumulation. Results: The results demonstrated that the cover crops residue had the potential to improve ex-nickel mining soil quality. The highest soil improvement was recorded in total nitrogen (700-800%). The treatments also showed a positive advantage to reduce heavy metals content, particularly for Fe, Mn and Zn by approximately 51.58-85.74%. No significant difference in corn growth performance was found in this study (p>0.05). However, the utilization of crop residue from Calopogonium mucunoides exhibited relatively higher total biomass than other treatments by around 3.08±1.99 g plant–1. Conclusion: Despite the treatments had no significant effect on corn performance. This study realized that cover crop residue could improve soil conditions for providing better environmental conditions for agriculture development.

  Background and Objective: Exploration of drought-tolerant endophytic bacteria is significant to identify bacteria that can provide plant resistance to drought stress. This study aims to obtain the potential of endophytic bacteria to promote plant growth from tomato plants in dry land. Materials and Methods: Exploration of endophytic bacteria from healthy tomato plants in a dry and rocky land, Muna Regency, Indonesia. Selection of drought-tolerant endophytic bacteria using polyethylene glycol 6000. Selected isolates were tested to increase the viability of tomato seeds using a Completely Randomized Design (CRD). Results: There were 123 isolates of endophytic bacteria isolated from the roots and stems of local tomato plants in a dry and rocky land, Muna Regency, Indonesia. There were 39 (31.70%) isolates sensitive to drought, 55 (44.71%) isolates very sensitive to drought, 8 (6.50%) isolates tolerant to drought and 21 (17.02%) isolates very tolerant to drought. Dryness for the maximum polyethylene glycol concentration at osmotic pressure of -2.00 MPa. Inoculation of endophytic bacteria in local tomato seeds increased the viability and vigour of local tomato seeds compared to the absence of endophytic bacteria. Of the 21 isolates of drought-tolerant endophytic bacteria, there were 12 potential isolates in increasing the viability of local tomato seeds belonging to the Pseudomonas sp. and Bacillus sp. bacterial groups. Conclusion: Pseudomonas sp. and Bacillus sp. isolates identified the endophytic bacteria, which can be drought-tolerant and increase tomato seeds' viability.

  Background and Objectives: The main constraint on the development of buffalo in Southeast Sulawesi is the poor quality of the feed in the pasture, so growth tends to be slow and there is high mortality. The study aimed to investigate the response of selected heifer buffalo to feed improvement. Materials and Methods: The research was performed using a Completely Randomized Block Design (CRBD). There were 4 treatments based on the type of feed: T1 (natural grass), T2 (natural grass+concentrate (1 kg sago hampas+1.5 kg rice bran), T3 (elephant grass) and T4 (elephant grass+concentrate). Results: Treatments T2 and T4 produced average daily gains (0.502 and 0.574 kg head1 day1) respectively, significantly higher (p<0.05) than that with feeding on T1 or T3, which produced only 0.338 and 0.427 kg head1 day1, respectively. The addition of concentrate also decreased the value of feed conversion, i.e., those for T4 and T2 were only 8.637 and 10.160 kg head1 day1, respectively, significantly lower (p<0.05) than the T1 and T3 values of 11.463 and 14.928 kg head1 day1, respectively. Conclusion: The selected heifer buffalo showed a positive response to the feed improvement in the form of high daily gain and low feed conversion.
