GROWTH OF DIFFERENT MORINGA VARIETY AS REHABILITATION PLANT MATERIAL ON MARGINAL LANDS Abd. Hadid, Bau Toknok, Wardah, Abd. Syakur Agrotecknology Department, Agricultural Faculty, Tadulako University Abstract Rehabilitation of marginal land is important to act as an effort to restore, maintain, and improve land function. However, the success of the rehabilitation program has not been optimal yet, this may be caused by the types set out in these activities are not site-specific and socially adaptive. Tree species determination in rehabilitation programs generally do not consider the limiting factors of the location, including slope tophography, poor in nutrients, low organic matter, low or high of soil pH. Moringa plants are able to adapt to extreme dry conditions and on low-fertility soils, so it is very conditional to be planted on marginal land rehabilitation. This proves that marginal land could be optimized the productivity through Moringa plant-based rehabilitation activities. However, the main obstacle in the development of a commodity is the availability of plant material that is ready for planting in large quantities. The long-term objective of this study is the establishment of a Moringa-based rural agro-industry on marginal lands. Whereas, the specific objective is to assess the growth of various varieties of moringa seedlings in various conditions of the growing environment (growing medium and light intensity) so that they may be even more adaptive on marginal lands. The study was conducted on community-owned land in Pangi Village, North Parigi District, Parigi Moutong Regency, using a factorial pattern randomized block design (RBD), which consists of three factors, namely variation in variety (J1, J2, J3, J4, J5), variations in growing medium (M1, M2, M3, M4) and variations in light intensity (C1, C2, C3). The results showed that there was an interaction between treatments on the observed parameters of plant height and number of leaves. The best on seedling height is the coarse yellow-stemmed moringa which is seeded on sandy soil under shading intensity of 75%. Whiles the parameters of the number of leaves, moringa seedlings that are able to form the most leaves are ash green stemmed varieties on sandy soils under shading intensity of 25%.

Given that soil, food, and animal breeding are the domains men occupy, some women writers tried to counter such stereotypes through their stories. Willa Cather in My Antonia argues that women can excel world^s patriarchal determination of women^s powerlessness through their giant power behind their softness. This article aims to investigate how Willa Cather depicted women^s extraordinary roles on land opening and early agricultural activities in the USA. Through a feminist perspective, this study will answer 4 questions: (1) how Cather portrays nature, (2) how Americans live agricultural life, (3) how women played their significant roles in the frontier life, and (4) what is the connection between creative writing and ideology. The research shows that Cather represents some extraordinary women who have contributed a lot to development of agriculture in America frontier life. Their effort to some degree has excelled their physical capacity that some men might not be able to do. They have a duty to fight for their family survival.

Effect of Shoot Pruning and Chicken Manure on Fruit Set and Yield of Cayenne Pepper Grown on a Sandy Dryland Soil I Komang Damar Jaya, Amrul Jihadi, Sudirman Department of Agronomy, Faculty of Agriculture, University of Mataram, Indonesia ikdjaya[at]unram.ac.id Abstract Improving the soil properties of a sandy dryland and carbohydrate allocation in crops grown on it is vital for crop production. This study explores the potential benefits of applying chicken manure and shoots pruning on fruit sets and the yield of cayenne pepper (Capsicum frutescens L.) grown on sandy dryland soil. An experiment testing a hybrid variety of cayenne pepper (Dewata 43) was conducted in Gumantar village, North Lombok, Indonesia (8.253654 S, 116.285695 E). Chicken manure treatment consisted of three levels- no chicken manure, chicken manure, and trichoderma-enriched chicken manure at 3.5 ton ha-1. Pruning consisted of two levels- unpruned and pruned at three weeks after planting. The treatments were arranged factorially in a randomized block design with three replications. The study revealed that the soil was low in organic matter and had low nutrient content. Pruning did not show a significant effect, but chicken manure affected the fruit set and yield of cayenne pepper. Trichoderma-enriched chicken manure produced the highest fruit set (93%) and fruit weight per plant (286 g). The highest yield up to the fifth harvest was much lower than the variety^s yield potential, indicating room for improvement in cayenne pepper production in sandy dryland soils.

This research was conducted to increase the yield and quality of corn through the application of inorganic fertilizers, and the utilization of corn for noodles that support food security. This research was carried out in two stages, the first stage was to determine the effectiveness of NPK 26-12-12 fertilizer on the yields and quality of corn. Corn with the best quality obtained from the best treatment of fertilization results at the first stage, is used as raw material in the second stage- namely noodles production. Corn is processed into corn flour, then corn flour is used as an ingredient for noodle production. Noodles are very popular in the community as an alternative to staple foods other than rice, so corn noodles can support food security through the use of local food. The second stage is to determine the quality of noodles with corn raw materials derived from the best treatment of fertilization results at the first stage. The factors that were used in the first stage were the combination dose of NPK 26-12-12 + urea + KCl which was compared to NPK 15-15-15 + urea + KCl (there are nine treatments, three replications). The factors that were used in the second stage was the percentage of corn flour (0- 10- 20- 30- 40- 50- 60%) to make noodle (three replications). The results of the first research found that the application of NPK fertilizers can increase the vegetative growth of corn plants, the results of observations of the components of corn yields that are most effective in increasing corn crop production, there is a G treatment with a value of RAE 181 which produces a corn harvest weight of 6.94 t/ha and the R/C ratio value of 1.56. The results of the second research found that the addition of corn flour affected the physical, chemical, and organoleptic properties. Panelists like noodles with the addition of 30% corn flour.

Grafting Technology Supports Increased Productivity Nutmeg in Indonesia Suryadi R., Trisilawati O., and Darwati I Badan Riset dan Inovasi Nasional (BRIN) National Research and Innovation Agency Abstract Abstract. Plant material determination is a critical factor in developing an agricultural commodity. If you choose the wrong plant material, especially for annual plants, you will suffer losses such as low productivity. Fixing it will take quite a long time and a relatively high cost. The productivity of Indonesian nutmeg in 2019 was 548 kg/ha, which is considered low compared to other nutmeg-producing countries. One of the reasons is that nutmeg plants are still developed using plant material derived from seeds, causing nutmeg plant flowers on both sides (dioecious) to be classified as male, female, or hermaphrodite. Because the sexes cannot distinguish at the seed stage, nutmeg plantations generally have many male plants (40 percent) that do not bear fruit, while only 5 percent are required to pollinate female flowering plants. The problem of propagation through seed can be solved by grafting. Grafting nutmeg plants has been studied with a high success rate (>80%). Therefore, the sex can be determined at the seed stage based on scion taken from male or female trees. When 95 percent of female and 5% of male plants are planted in the field, the number of plants bearing fruit can be calculated. Fruit is more significant, and productivity is up.

Muara Bangka Hulu, Sumatera, Bengkulu Indonesia 38371 Abstract Salak is an indigenous Indonesian fruit susceptible to point end rot disease. Disease control during storage is crucial to maintain the quality of the fruit until it reaches consumers. The study aimed to determine the effectiveness of cinnamon (Cinnamomum burmanii) and clove (Syzygium aromaticum) oil vapour in controlling the causal agent of point end rot on salak. Morphological identification of pathogenic fungi causing point end rot disease was carried out by observing macroscopic and microscopic morphology using a 40x magnification microscope. Genomic DNA amplification of isolates was using Internal transcribed spacer (ITS) primers 1 and 4. The assay with vapour exposure was using three concentrations (4, 8, and 12 ul) of cinnamon and clove oil, respectively and without essential oil, with four replicates and 3 Petri dishes as treatment units. The parameter was percent of mycelial growth, diameter of colony and fungal viability. The result showed that based on morphological and molecular characterization of the SB1 sample, the pathogen could be classified as C. paradoxa. Clove and cinnamon oil vapours with concentrations ranging from 4 ul can inhibit the growth of C. paradoxa fungi in vitro. The lowest fungal viability was when exposed to clove and cinnamon essential oils with 12 ul and 8 ul, respectively.

Effect of various formulations of Piper aduncum botanical pesticide and concentration levels on fungal pathogen Fusarium oxysporum f.sp. cubense Vegetative Compatibility Group (VCG) 01213/16 Tropical race 4 and VCG 01218 race 1 Nurmansyah (a), Herwita Idris (a), Riska (a*) a) Research Center for Horticultural and Crops, Cibinong Science Center, BRIN Jl. Raya Jakarta-Bogor, Cibinong, Bogor Indonesia 16915 Abstract Fusarium oxysporum f.sp. cubence (Foc) Vegetative Compatibility Group (VCG) 01213/16 Tropical race 4 and VCG 01218 race 1 are pathogens that cause wilt disease in banana plants (Musa spp) and can survive for a long time in the soil by forming chlamydospores. This disease can still be controlled using synthetic fungicides, but this method can cause damage to plants and ecosystems. Plant-based pesticides are an alternative to control plant pathogens that are environmentally friendly because they use raw materials made from plants. This study aims to obtain a formulation of Piper aduncum oil with several essential oils to suppress the growth development of two Foc strains that cause wilt disease in banana plants. This study used a complete randomized design in factorial, where the first factor is the type of formulation: F1 = 25% P. aduncum leaf oil, F2 = P. aduncum leaf oil with lemongrass leaf oil (Cymbopogon flexiosus), F3 = P. aduncum oil with citronella leaves (Andropogon nardus), F4 = P. aduncum oil with Ceylon cinnamon leaf oil (Cinnamomum zeylanicum), F5 = P. aduncum oil with Padang cinnamon leaf oil (C. burmanii), F6 = P. aduncum oil with clove leaf oil (Eugenia aromatica) F7=P. aduncum oil with wild ginger oil (Elettariopsis slahmong). The second factor is the concentration level: K1 = 1000 ppm, K2 = 2000 ppm, and K3 = 3000 ppm. The results showed that diameter of mycelium between Foc VCG01213/16 Tropical race 4 and VCG01218 race 1 did not differ significantly. However, there were significant differences in the botanical pesticide formulations used. P. aduncum oil formulation mixed with clove leaf oil and Ceylon cinnamon oil at a concentration level of 3000 ppm had better inhibition of colony diameter, namely for Foc VCG01213/16 Tropical race 4 (90.55% and 88.08%) and on Foc VCG 01218 race 1 (90.72% and 89.85%). Likewise, for the inhibition of colony biomass, the best formulation is the P. aduncum oil mixed with clove leaf oil and with Ceylon cinnamon oil, the concentration level at 3000 ppm for Foc VCG 01213/16 were 96.64 and 95.80%, respectively. In contrast, for Foc VCG 01218 race 1 were 96.00% for both.
