Abstract

Dryland is a potential food production in the future and sorghum is one of the potential commodities to be developed. Sorghum has been cultivated by a small number of people in Ende Regency, such as in Kotabaru and Nangapanda sub-districts. However, the cultivation has not yet applied cultivation techniques to achieve production optimization. In addition, there are still many limitations in knowledge of processing the production of sorghum seeds, leaves, and stems. Farmers have not enjoyed and received the benefits of cultivation so far. The purpose of this study is to increase awareness, understanding, and knowledge about the importance of sorghum to support food security and farmer welfare in Ende Regency, and to map the potential of online learning for farmers. The online learning was carried out in Kotabaru Village with the target being the Kema Sa Ate Women Farmers Group (KWT), which are sorghum cultivators. Learning is carried out using the lecture plus method (lecture-discussion) using a zoom meeting. Learning materials about harvesting and post-harvesting sorghum. The obstacle faced in this online learning is a device that does not support it. This problem was solved by involving a learning facilitator played by Field Agricultural Extension (PPL). Participants' initial knowledge before the training program was 3.8 and after training the final knowledge was 7.2. Based on the initial and final knowledge, it can be concluded that there is an increase in knowledge of 89.5%. The level of participant satisfaction with the 5 indicators proposed in the evaluation of the learning implementation process is very high, more than 80%. The level of participants' satisfaction with the five indicators in the evaluation of the training process also increased. More than 90% for problem solving in the field, speaker competence, and the level of urgency of information, while for media innovation and training methods more than 80%.

Abstract

Indonesia has a great taro diversity and had been utilized for long time. Taro has more competitiveness including high nutrition, wide adaptation, and ease for cultivation, further, it’s very potential to be the future food and create new economical value. The objective of the research was to obtain the organic manure fertilizer effect on sutra taro variety growth and yield. The research was conducted for eight months from January till August 2021 at Leuwikopo Farm, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University. A Completely Randomized Block Design (CRBD) with five replications and four-level organic manure treatments (0.25 kg, 0.5 kg, 0.75 kg, and 1.00 kg per plant) was applied. Taro growth, corm characters, and yields were affected by organic manure fertilizer dose. The dose of 0.75-1.00 kg/plant (equivalent to 15-20 ton/ha) showed the highest growth, corm characters and yields more than the lower doses. Taro “Sutra variety” cultivation by fully using organic manure fertilizers is very potential to be encouraged.

Abstract

Bogor is one of the centers of taro production, but productivity is low. It was caused by the use of low-quality seeds. The use of good quality of seed will increase taro productivity and production. Good quality seeds were uniform in size, clean, free from other varieties, and had high viability (vigor). This training was aimed at capturing the taro farmer's condition, cultivation technique, and knowledge about good quality of seed. The training was conducted in KTD Saluyu from August to September 2022 and was attended by 25 farmers. Training activities included expert presentations, discussions, and interviews. Evaluation of farmer knowledge change was determined by pre- and post-tests, while the effectiveness of training activities was evaluated to improve its effectiveness in the future. Taro farmers were dominated by men, aged about 40–59 years old (58.3%) and more than 60 years old, and almost all of their education background was elementary school. Farmers cultivated taro by sharing profit land (58.3%), ownership land (33.3%), and rent land (8.3%). Taro production was dominated by less than 1 ton, the monoculture system about 66.7%, and intercropping about 33.3%. Planting material was by farmer own seed from the previous season because there were limited certified seeds. Farmer knowledge increased by about 45.8% (from 4.9 to 7.2). This training was held under good management, as shown by the training evaluation score of about 90%. This training requires that it be held more intensively and sustainably through intensive assistance in the field and a seed production demonstration.

Abstract

Sweet corn is one of the most popular crops in Southeast Asian countries, including Indonesia. Superior sweet corn varieties breeding is important to do in order to improve the quality and productivity of sweet corn in Indonesia. Plant breeding programs rely on genetic quality variability and heritability information. Therefore, this study aimed to evaluate the performance and genetic variablity of various sweet corn inbred lines to determine the best prospective parents for hybridization. The study was conducted at the Leuwikoppo experimental field of the Department of Agronomy, Faculty of Agriculture, IPB, from January to March 2022. Twelve sweet corn inbred lines were planted in the field using a completely randomized block design with three replications. Analysis of variance, estimation of the genetic parameters, broad sense heritability, genetic and phenotypic coefficients variability and cluster analysis were carried out in this study. The results showed that there were differences in qualitative and quantitative characters between the tested sweet corn genotypes. Plant height, ear height, stem diameter, ear length, and ear weight had a high broad sense heritability and moderate to high of genetic coefficients of variability. SM12-2 and T10-3 lines become the prospective parents generating a high cob weight and seed sweetness.ABSTRAK Jagung manis merupakan salah satu tanaman yang sangat populer di negara-negara Asia tenggara, termasuk Indonesia.

Abstract

Cayenne pepper is one of the important horticultural commodities and has high economic value for Indonesian people. The demand for cayenne pepper in Indonesia was relatively high, especially for household consumption. Therefore, superior varieties were needed to meet the needs of cayenne pepper in Indonesia. One way to guarantee the superiority of varieties and the validity of variety descriptions was to conduct yield testing. Our research aims to evaluate the performance and yield of seven genotypes of cayenne pepper. This research was carried out from March 2023 to September 2023 at Leuwikopo Experimental Garden, IPB University. It consisted of one factor: ten genotypes (seven genotypes and three control varieties). Experimental design in our research using randomized complete block design with three replications. The results showed that there were differences in performance and yield between cayenne pepper genotypes. The flowering ages of all genotypes ranged from 41.33 - 45.67 DAP with the harvest ages ranging from 83.33 - 92.67 DAP. The percentage of plants observed at the end of harvest ranged from 37.50 - 70.83% with the Rawita F1 variety showing the lowest percentage (37.50%). F1.372340 genotype was the highest productivity genotype, reaching 4.80 t.ha-1. The productivity of F1.372340 was higher than control varieties, which ranged from 1.48 to 2.72 t.ha-1. Line’s genotype had a shelf life ranging from 9.30 - 15.00 DAH which was the same or better than the control varieties which ranged from 9.67-12.33 DAH.

Abstract

[EFFECT OF STORAGE METHOD ON QUALITY OF BAMBARA GROUNDNUT (Vigna subterranean L.) SEEDS]. Bambara groundnut is a legume that has potential as a food crop. Bambara groundnut seeds are usually stored in their pods. The used of pod storage can reduce storage capacity and increase seed weight on distribution. This research aims to study the effect of pods and packaging types on the viability and vigor of bambara groundmut seeds so as to obtain a safe and efficient storage method. A randomized complete design was employed, consisting of two factors. The first factor was the seed storage method (four levels): seeds with pods in PP-plastic, seeds with pods in plastic sack, seeds without pods in PP-plastic, and seeds without pods in plastic sack packaging. The second factor was storage period: 1 to 6 months. Storage was carried out in a room at 20 °C and RH 65%. The results showed that plastic packaging is absolutely necessary to maintain seed moisture content (mc) because the pods could not maintain it. Seed in plastic sack packaging had mc of 11,1% - 11,4%, while initial seed has mc of 9,0%, seed stored in PP-plastic had mc of 9,4% - 9,6%. Pod removal suppressed fungal infection. Fungal infection of seeds stored in plastic packaging without pod (17,11%) was lower than seed with pods (44,00%). Vigor of seed stored without pods in PP-plastic was better than others. Moreover, storage of bambara groundnut seeds without pods can reduce storage space requirements (64,62%) and reduce seed transportation weight (25,89%). Bambara seed should be extracted from the pod and save in PP plastic packaging in order to keep the seed vigor and efficient in storage requiirement.
