Abstract

Growth and Production of Three New Rice Varieties in Prima Tani Mandailing Natal. The use ofNew Rice Superior Variety has a future prospect. It is not only high productivity but also reduces the risk ofcrop failure. This Assessment was aimed to study growth performances, yield component, and production ofthree types of New Rice Superior Varieties of Seed Stock (SS) at Prima Tani Location in Ipar Bondar Village,Mandailing Natal District, North Sumatera. The study was done by 5 farmers in their own rice field with totalof farm area used was 4 ha. Cultivation for seed production of new seed variety (NSV) was done in dry season(March-July 2008), while seed processing was executed in August 2008. Rice varieties used were Mekongga,Conde dan Angke. The seeds used was originated from Indonesian Center for Rice Reseach at Sukamandi, withthe method of paddy cultivation followed the Integrated Crop Management (ICM) approach. The research useda Random Block Design with 5 repetation. The result showed that Mekongga variety gave highest yield of 8.30t/ha , Conde 7. 7 t/ha, and Angke 7.80 t/ha. Data were analysed using descriptive of rice productivity to comparerice productivity among varieties. Improvement productivities of Conde, Angke, and Mekongga was .67-2.80t/ha (the average of 2.26 t/ha) or increase between 30.36 - 50.90% (with the average of 4 .09%), compare withCiherang (5.5 t/ha) in location area. Total rice seed production of SS seed class was 38.5 t. The seed of NSV wassold Rp.5,200/kg per package and has been distribute to 37 villages of 0 sub-districts in Mandailing Natal District.It was concluded that the Mekongga variety gave the highest yield of 8.3 t/ha of dry grain harvested, comparewith two other variety. Thus, these varieties can be developed for seed multiplication. While, Conde and Angkevarieties are also an alternative varieties to be developed in this location because their production are also high.Key words: Paddy seed source, new rice superior varietyPenggunaan Varietas Padi Unggul Baru ditingkat petani cukup prospektif, selain memiliki produktivitasyang tinggi juga mengurangi resiko gagal panen.

Abstract

Agro Industrial Growth of Rice Seed in Prima Tani Location, Konawe District, Southeast Sulawesi.High quality of seed is one of the key factor for the success for increasing production of lowland rice. However, in “Prima Tani” location at Konawe District farmers have difficulties in obtaining high quality seed of lowland rice. This because they lack of information on how to get certified seeds. In addition, they don’t know yet on how to producehigh quality (certified) seeds. Therefore, We justify that in this location the activity of growing rice seed producers is very important, and it will be the form of Rural Agro Industrial Unit (“AIP/Agro Industri Pedesaan”). This research was conducted at Karandu Village of Wawotobi Sub-District, Konawe District - Southeast Sulawesi during June –December 2007, with the objective to have comprehensive understanding on the advantages of producing certifiedseed as compared to producing rice for consumption based on the economic analysis of those two activities, as well as to know the linkage among supporting related institutions for the purpose of rice seed producers in the area.Descriptive analysis and economic analysis, such as RCR and MBCR, were used. The result shows that the Rural Agro Industry on rice seed production in “Prima Tani” location at Konawe District can be established. In those Rural Agro Industry, the link among institutional and functional institution have also been shown. The production of rice seed in the “Prima Tani” location shows advantages economically ascompared to those for rice consumption.Key words : Producing seed, rice, rural agro industry, Prima TaniBenih bermutu merupakan salah satu faktor kunci peningkatan produktivitas padi sawah. Namun demikian, di tingkat petani di lokasi Prima Tani Kabupaten Konawe benih bermutu sulit diperoleh, disebabkan kurangnya informasi bagi petani mengenai cara mendapatkan benih bermutu. Selain itu, di lokasi ini belum ada penangkar benih yang disebabkan teknologi penangkaran benih belum dikuasai. Oleh karena itu diputuskan untuk melaksanakan kegiatan penumbuhan penangkar benih padi di wilayah ini, yang sekaligus akan dijadikan suatu bentuk Agro industrial Pedesaan dalam bentuk Agro Industri Penangkaran Benih Padi. Pengkajian dilaksanakan di lokasi Prima Tani Desa Karandu, Kecamatan Wawotobi, Kabupaten Konawe, Sulawesi Tenggara pada bulan Juni – Desember 2007.Pengkajian bertujuan untuk memahami secara lebih komprehensif tentang perbedaan keuntungan ekonomi antara produksi padi untuk benih dan produksi padi untuk konsumsi. Pada pengkajian ini juga dievaluasi tentang keterkaitan antara institusi pendukung dalam penumbuhan Agro Industri Pedesaan Penangkaran Benih Padi. Analisis deskriptif dan analisis ekonomi seperti penghitungan nilai RCR dan MBCR dilakukan pada kajian ini. Hasil pengkajian menunjukkan bahwa Agroindustri Pedesaan dalam Penangkaran Benih Padi di lokasi Prima Tani Kabupaten Konawe dapat diwujudkan. Pada Agro Industri tersebut, ditunjukkan pula keterkaitan antar istitusi/kelembagaan yang mendukung tumbuhnya Agro Industri Penangkaran Benih padi di pedesaan. Pengkajian ini juga membuktikanbahwa usahatani penangkaran benih padi lebih menguntungkan dibandingkan dengan usahatani padi untuk konsumsi.Kata kunci : Penangkaran benih, padi, AIP, Prima Tani

Abstract

State Law No. 12/92 on agricultural systems for food crops stated that good quality seeds is seeds of correct and pure variety with high genetic, physiological and physical qualities, and in accordance with the quality standard of its class. The demand for groundnut seeds were almost entirely fulfilled by informal seed supply, which may come from a traditional system (farmers use their own seeds), buying from agricultural shops that process their own harvested pods into seeds, or buying from informal seed growers. Whilst the certified seeds produced by official seed growers is very limited in amount and supplys only a small portion of the total national seed demand. Under such condition, selection for seed quality is mainly based on the physical seed condition, such as seed size, brightness of seed coat color, and maturity of seeds. In other words, farmers prefer to select sound mature kernels and reject the shriveled kernels. Research results, however, indicated that plants generated from shriveled kernels were not significantly different to those generated from pithy kernels in term of growth and pod yield. Given the high cost and limited stocks of seed during the high planting season, it is advisable seed sorting process is not too tight and the use of wrinkled seeds for planting is prioritized. When there are overstock seeds, it is suggested to keep the sound or pithy seeds or to consume these seeds for food safety issue. This is because research results showed that shriveled seeds are more susceptible to Aspergillus flavus infection and aflatoxin contamination than the pithy seeds.

Abstract

The productivity of cassava in acid dryland is generally still low. Fertilization, land amelioration, and superior varieties are the main solutions for increasing cassava productivity. This research aimed to determine the response of high-yielding varieties and fertilization technology packages to the growth and yield of cassava in acid dryland of Sukaharja Village, Warung Kiara District, Sukabumi Regency, West Java. The contents of organic carbon, nitrogen, and magnesium of the soil is below the minimum threshold, so the application of N fertilizer, organic matter, and ameliorant is expected to increase plant growth. The research consisted of two treatment factors: two cassava varieties and three fertilization technologies. The treatments were arranged in a completely randomized split-plot experimental design with three replications with variety as the main plot and fertilization technology package as the subplots. The treatment effect was observed on the character of plant height, wet biomass weight, stem diameter, number of tubers, tuber length, tuber diameter, tuber weight (large and small) per plant, and tuber yield per plot to be converted per ha. Tuber quality was observed by observing water content, percent dry matter, and starch yield. The results showed that the fertilization technology package increased plant height, fresh biomass weight, stem diameter, large tuber weight per plant, and yield per hectare in both varieties. Differences in varieties and fertilization technology packages have no effect on starch levels.

Abstract

Etiella zinckenella is a significant pest of peanuts in Indonesia, causing pod yield losses of up to 100% in infested fields. This study aims to identify an appropriate strategy for the sustainable management of E. zinckenella by validating the effectiveness of various integrated pest management approaches through field trials. The experiment was conducted in two locations, Natar (Lampung) and Muneng (East Java), using 11 treatment combinations with three replications. The peanut variety planted was Gajah (GH 51). The treatments included a range of pest control technologies, such as seed treatment with thiamethoxam, application of carbofuran, neem seed powder (NSP), release of Trichogrammatoidea bactrae-bactrae, application of Spodoptera litura Nuclear Polyhedrosis Virus (SlNPV), trap crops (Crotalaria, soybean, maize, mung bean), organic fertilizer, and lambda-cyhalothrin. The findings revealed that the population density of pod borers and the extent of pod and seed damage were higher in Natar than in Muneng. In Natar, pod damage ranged from 43.7% to 76.3%, with the highest levels recorded in untreated plots and those treated with lambda-cyhalothrin. Similarly, the highest pest population densities in Natar were observed in untreated plots and those treated with lambda-cyhalothrin. In contrast, Muneng exhibited significantly lower pod damage, ranging from 0.2% to 2.6%, with the highest recorded damage at 2.64%. The most effective pest management strategy in both locations was a combination of thiamethoxam seed treatment, carbofuran, NSP, T. bactrae-bactrae, SlNPV, and Crotalaria trap crops, which reduced pod damage to 43.7% in Natar and 0.2% in Muneng. These results suggest that an integrated pest management approach effectively mitigates E. zinckenella infestations in endemic areas. This method not only minimizes pest damage but also helps maintain populations of natural enemies, including Formicidae, Coccinella sp., Paederus sp., and Oxyopes sp., thereby supporting ecological balance. Furthermore, trap crops such as maize, soybean, and mung bean, when planted around peanut fields, demonstrated considerable efficacy in reducing pest attacks compared relative to chemical insecticides, highlighting their potential for a sustainable pest management strategy.
