Abstract

Rice (Oryza sativa L.) is an annual crop that plays an important role in meeting the food sources of the Indonesian population. In addition, rice plants have a diversity of insects as their natural enemy. This study aims to determine the population of natural enemies of 3 rice varieties, namely Inpari 30, Ciliwung, and Mekongga varieties. The research location is the rice fields in Turikale Subdistrict, Maros District. The method used for the study was the survey location of rice fields with each paddy field size of about 20 x 15 m. The results showed that there were 3 types of predators namely Lycosa, Coccinella, and Orthetrum which were found in each variety with varied total numbers at every 2-week observation interval. The highest population of Lycosa was found in the Inpari 30 (6 wap) variety, the highest Coccinella population also was found in the Inpari 30 (10 wap) variety, while the highest Orthetrum population was found in the Mekongga variety (6 wap). The highest proportion of each variety was Lycosidae 50% in the Inpari 30 variety, Lycosidae 51.35% in the Ciliwung variety, and Lycosidae 44.44% in the Mekongga variety

Abstract

The need for Shallot at the community level continues to increase every year in line with the increase in population. Shallots are used as cooking spices and used in the herbal medicine industry. Minahasa Regency is one of the centers of shallot development in North Sulawesi, where production at the farm level is still below the average of 7-8 t/ha. For this reason, a breakthrough in cultivation technology innovation is needed to increase yields. This writing aims to provide information on technological innovation support in the effort to develop local superior shallots in North Sulawesi and to see the results of farming from the application of the technology. The data obtained from the results of interviews and research results both conducted by the North Sulawesi AIAT Assessment Team and other research results. The support of technological innovation in efforts to develop shallots is the application of onion PTT Innovations: land management, preparation of plant spacing, use of certified seeds, planting and fertilizing, watering and controlling weeds, controlling plant pests, harvesting and post-harvesting. The conclusions obtained by the application of PTT shallots, which were examined by BPTP North Sulawesi using local varieties Lansuna. The B / C ratio is 4.23 by giving an income of Rp. 273,058,000 compared to the way of farmers where B / C ratio = 2.23 with income of Rp. 138,233,000 / hectare

Abstract

Planting material or seed is the most determinant factor for oil palm productivity alongside agro climatological and management considerations. A study was conducted to determine the different varieties of oil palm planted in smallholders’ plantations, the distribution channels for oil palm seeds and all the actors involved in the seed trade sector in Cameroon. This is a bid to secure the supply of only improved planting materials to smallholder farmers. 230 oil palm smallholder plantations were surveyed and individual palms were subjected to varietal determination. The Chi-Square Test (c2) for Fixed Ratio Hypothesis (= 0.05) was used to determine whether the observed ratio deviates significantly from the Mendelian hypothesized genetic segregation ratio. Up to 65% of smallholder farms were found to be planted with poor planting material distributed in the different Mendelian ratios; 100% Dura, 50% Tenera and 50% Dura (1:1), 25% Dura, 50% Tenera and 25% Pisifera (1:2:1). The source of this poor quality planting material for these farms was deduced to come from private nursery entrepreneurs and workers of industrial plantations such as the Cameroon Development Corporation (CDC), Cameroon Palm Oil Company (SOCAPALM), Common Initiative Groups (CIG’s) and Non-Governmental Organisations (NGO’s). Farmers supplied by government services especially the Ministry of Agriculture and Rural Development and some of its specialized development projects all received good quality material. Thus, this is the only means now available which can assure the distribution of seeds good quality seeds

Abstract

This study was aimed to find out the effective local microorganism of fruit wastes concentration on the growth and production of the soybean plants. This study was conducted in the trial land of Campus 2, Faculty of Agriculture, Cokroaminoto University, Palopo from September to December 2019. The method used in this study was the randomized block design with 5 treatments and 4 replications, therefore there were 20 experimental units. Each experimental unit comprised 2 plant units, therefore there were 40 plant samples on the given concentration of P0: Control, P1: 50 mL/L fruit waste local microorganism concentration, P2: 100 mL/L fruit waste local microorganism concentration, P3: 150 mL/L fruit waste local microorganism concentration, and P4: 200 mL/L fruit waste local microorganism concentration. The results showed that the local microorganism application on the soybean plants had no significant effects on the plant height, total of leaves, flowering period, and a total of pods. The local fruit waste microorganism with 100 mL concentration was capable of improving the plant height, total of leaves, flowering period, and a total of pods with the respective average of 31.9 cm, 51.6 leaves, 21,8 days, and 35 soybean pods

Abstract

Chrysanthemum (Dendranthema grandiflora) is an ornamental plant that has high economic value, including flowers that are in great demand at domestic or abroad.  As cut flowers, chrysanthemums are used for decoration and flower arrangements at weddings, and for opening new offices.  The quality of cut flowers depends on the appearance and durability of freshness. Flowers with prime quality have a higher sale value compared to low-quality cut flowers. To maintain the quality of prime cut flowers still need to be implemented several treatments, especially when the flowers are ready to harvest to the consumers.  The handling of post-harvest chrysanthemums is an important factor that is inseparable from the stages of cultivation and greatly influences the selling value and added value that will be obtained by farmers and traders. The use of pulsing and holding liquid during display will extend the chrysanthemum vase life. By implementing post-harvest chrysanthemums in accordance with handling procedures (SOP), chrysanthemums will be obtained that can meet quality standards and can provide added value for farmers and flower traders

Abstract

Seed viability is one of the most important physiological quality benchmarks of seeds. The use of appropriate germination media can affect the results of seed viability testing. This study aims to determine the optimal germination media in tobacco seed viability testing. This research was conducted at the Seed Laboratory of the Indonesian Sweetener and Fiber Crops Research Institute, Malang in January - March 2019. The research method used a two-factorial randomized block design (RAK). The first factor is tobacco seed varieties consisting of Kasturi in 2007, Bojonegoro in 2012 and Kemloko in 2014. The second factor is the seed germination media consisting of straw paper, cotton, towel tissue, paperboard and newspaper. The results showed that the Kemloko variety of tobacco seeds germinated in the towel tissue had the best seed vigor and viability percentage. Seed germination media with paperboard, towel tissue and straw paper can be used to test the viability of tobacco seeds because they have a percentage of simultaneous growth, percentage of the growth speed, percentage of germination, percentage of the growth potential maximum and normal seedling dry weight which are equally well
