Ginger (Zingiber officinale Roscoe) var. Bentong is a monocotyledon plant that belongs to the Zingiberaceae family. Bentong ginger is the most popular cultivar of ginger in Malaysia, which is conventionally propagated by its rhizome. As its rhizomes are the economic part of the plant, the allocation of a large amount of rhizomes as planting materials increases agricultural input cost. Simultaneously, the rhizomes’ availability as planting materials is restricted due to the high demand for fresh rhizomes in the market. Moreover, ginger propagation using its rhizome is accompanied by several types of soil-borne diseases. Plant tissue culture techniques have been applied to produce disease-free planting materials of ginger to overcome these problems. Hence, the in vitro-induced microrhizomes are considered as alternative disease-free planting materials for ginger cultivation. On the other hand, Bentong ginger has not been studied for its microrhizome induction. Therefore, this study was conducted to optimize sucrose and plant growth regulators (PGRs) for its microrhizome induction. Microrhizomes were successfully induced in Murashige and Skoog (MS) medium supplemented with a high sucrose concentration (>45 g L−1). In addition, zeatin at 5–10 µM was found more effective for microrhizome induction than 6-benzylaminopurine (BAP) at a similar concentration. The addition of 7.5 µM 1-naphthaleneacetic acid (NAA) further enhanced microrhizome formation and reduced sucrose’s required dose that needs to be supplied for efficient microrhizome formation. MS medium supplemented with 60 g L−1 sucrose, 10 µM zeatin and 7.5 µM NAA was the optimum combination for the microrhizome induction of Bentong ginger. The in vitro-induced microrhizomes sprouted indoors in moist sand and all the sprouted microrhizomes were successfully established in field conditions. In conclusion, in vitro microrhizomes can be used as disease-free planting materials for the commercial cultivation of Bentong ginger.

The study attempts to determine the training needs of the farmers emphasizing nine selected major thematic areas. Under each major component, specific and relevant training needs item were collected and systematically incorporated into an interview schedule and administered in terms of frequency of training imparted. Four districts were purposively selected for the study and a total of eighty farmers were randomly selected from four districts. Primary data were analyzed using descriptive statistics. The study revealed that more male was involved in farming and 45% farmers were middle age category (30-39 years). Majority of the farmers completed primary level of education compared to other categories and family size of more than half (60 %) of the respondents was three. Majority number of respondents (57%) had more than 10 years farming experience. A small number of farmers (8.75%) had owned agricultural land and 45% had land between 0.50- 1 hectare. More than 75% of annual gross income of 57.50% farmers came from agricultural activities. More than half (55%) of the respondents collected information on crop and its varieties by own attempt while about 34% was informed from seed seller or dealer. Farmers in Chattogram district had first priority to get training on integrated pest and diseases management, production of bio control agents and bio pesticides, marketing and transportation. Water management, integrated pest and disease management, vermi-compost production, marketing and transportation ranked first in Khagrachori district. The areas of priority for training in Rajshahi district were production and management technology, processing and value addition, marketing and transportation, integrated pest and disease management, water management and vermi-compost production. Training on integrated pest and disease management, bio-control of pests and diseases, production of bio control agents and bio pesticides, production of off-season vegetables, vermi-compost production, marketing and transportation were most emphasized by the respondents in Rangpur district. Respondents defined identification of adulterated fertilizer, insecticide and pesticide application, disease and insects of mango varieties and fruit bagging system of mango as very good type of training. The study concluded that there is an urgent need to design regular training programs in identified thematic areas to fulfill the knowledge gap among the farmers of Bangladesh.Bangladesh J. Agril.

This study aims to determine the right planting time to obtain optimal sweet corn results in intercropping systems with peanut plants. This research was conducted in the Agricultural Land of Petobo Village, South Palu Village, Palu City, Central Sulawesi for 3 months starting from September to November 2017. The research was carried out using a one-factor Randomized Block Design (RBD), by grouping based on water sources. The treatments that were tried were the intercropping system (TS) planting time, as follows: TS0 = Sweet corn grown together with peanuts; TS1 = Sweet corn planted with 2 WAP peanuts; TS2 = Sweet corn planted with 4 WAP of peanut; TS3 = Sweet corn monoculture. Each treatment consisted of 3 replications so that there were 12 test unit plots. The results showed that the planting time treatment significantly affected the growth and yield of sweet corn on intercropping systems with peanuts. The treatment of planting time together between peanuts and sweet corn gave better growth than other treatments, but the sweet corn monoculture (TS3) treatment gave better results compared to other treatments. Good growth and yield of both plants is recommended at the same time between peanuts and sweet corn in intercropping systems

Ringkasan Perbanyakan tanaman teh [Camellia sinen­sis (L.) O. Kuntze] melalui stek tunas berdaun tunggal hanya dapat menghasilkan klon unggul dalam jumlah terbatas. Oleh sebab itu diperlukan metode alternatif dengan teknik kultur sel dan jaringan untuk perbanyakan klonal secara cepat. Dalam penelitian ini dikembangkan metode yang lebih efektif untuk regenerasi tanaman teh melalui embriogenesis somatik langsung. Massa pro­embriogenik dari eksplan kotiledon dihasilkan dengan frekuensi 56,7% dalam media MS padat setengah konsentrasi yang mengandung BAP 2 mg1L. Proliferasi, perkembangan, pendewasaan dan perkecambahan embrio somatik diperoleh dengan sistem perendaman sesaat (SPS) yang menggunakan media MS cair setengah konsen­trasi, yang diperkaya dengan zat pengatur tumbuh dengan berbagai konsentrasi. Proliferasi embrio meningkat 4,3 kali dalam media yang diberi BAP 2 mglL; perkembangan dan pendewasaannya meningkat dengan penambahan kinetin dan ABA masing-masing pada konsentrasi 0,1 mg1L yang 30% diantaranya berkecambah dan membentuk planlet tanpa penambahan zat pengatur tumbuh. Protokol SPS tersebut merupakan sistem in vitro yang berpotensi bagi proliferasi dan perkembang­an embrio somatik tanaman teh yang cepat dan sinkron dari kultur kotiledon, serta regenerasinya menjadi planlet tanpa melalui fase kalus.Summary Tea propagation by single-leaf bud cuttings has limited applications for rapid dissemination of planting materials from new elite clones. An alternative method for rapid cloning by cell and tissue culture technique is necessary. In this study we have established an improved method for tea [Camellia sinensis (L.) O. Kuntze] plant regenera­tion via direct somatic embryogenesis. Clumps of proembryogenic masses were initiated at a fre­quency of 56.7% from cotyledonary slices cul­tured on a half-strength MS agar-gelled medium supplemented with 2 mg/L BAP. Proliferation, development, maturation and germination of so­matic embryos were achieved using the temporary immersion system (TIS) provided with half­strength MS liquid media supplemented with varying concentrations of growth regulators. Em­bryo proliferation increased by 4.3-fold in me­dium provided with 2 mg/L BAP; their develop­ment and maturation were enhanced by the presence of both kinetin and ABA at 0.1 mg/L each. Germination and plant recovery were achieved at a frequency of about 30% without the use of growth regulators. The TIS protocol des­cribed above represents an in vitro system poten­tial for rapid proliferation and synchronized development of tea somatic embryos from cotyledon cultures, and their regeneration into plantlets without an intervening callus phase.
