Raised Bed

Trifoliate orange seedlings are used as rootstock for citrus crops due to cold hardiness and phytopthora disease tolerance. Nursery owners usually prepare raised bed in open field to sow seeds of trifoliate. The trifoliate seed production in government farms are very low compared to its demand due to limited number of fruiting trees. Further the germination percent in open nurseries are very low. Hence, production of grafted sapling is very much affected by unavailability of rootstock. Therefore, a study was carried out in National Citrus Research Program, Dhankuta to increase germination rate of trifoliate orange in the year 2016 and 2017. Trifoliate seeds were extracted from three stages of fruits (green mature, half yellow and full yellow) and sown at three dates (September 1st week, September 3rd week and October 1st week) at three raised bed (open field, 50-cm low plastic tunnel with or without sides open). The data on percentage seed germination was taken at 35, 50, 65, 90 and 210 days after seed sowing. The fruit maturity had no effect on germination percentage irrespective of sowing date and method of beds used. The date of sowing resulted significantly higher germination at earlier days but there was non-significant effect during final germination count. Plastic tunnel with open sides resulted 80% germination compared to 46% in tunnel side closed nursery. Hence, low plastic tunnel raised bed having open sides is the best option to raise trifoliate seed sown during 1st week of September to 1st week of October in agro-climatic conditions like Dhankuta.

Multiplier Onion

Multiplier onion is among the four groups of onions classified by horticulturists which is propagated through bulbs. Presently onion bulb planting is done manually by planting the root portion oriented downwards as pressed into an irrigated field. Generally about 80-100 man days are required to plant one hectare of onion at a spacing of 15 cm by 10 cm. The manual planting is labour intensive, highly drudgery involved and time consuming. There is need to develop an onion bulb planter possibly with four orientations. Therefore, an experiment was carried at ICAR-Indian Institute of Horticultural Research, Bengaluru to study the effect of different planting orientations of onion bulb on growth parameter. Onion bulbs were planted on raised bed 45 m long and 0.9 m width at 15 cm row spacing and 10 cm in-row spacing. The four treatments used were viz., T1) root portion up, T2) root portion down, T3) horizontal and T4) inclined. Experiment was laid as a randomized block design with 5 replications. The growth parameters namely i) germination percentage at 7th and 15th days after planting, (DAP), ii) Plant height 15th and 30th DAP and yield. The results showed that the growth parameters were on par in all the three treatments (root portion down, horizontal and inclined) except in treatment root portion up.

Objetivo: Analizar el proceso de producción y comercialización de café en la comunidad del Cerro Cuate, Iliatenco, en la región de la Montaña de Guerrero, México.Diseño/Metodología/aproximación: el trabajo se realizó por; 1) investigación documental), 2) selección del área de estudio, 3) Entrevista estructurada con preguntas abiertas a 22 cafeticultores, soportada con la técnica de encuesta seccional y la herramienta de cédulas de entrevistas, y 4) análisis de la información. El tamaño de muestra se definió por el método de muestreo por conveniencia, y la selección de las unidades de análisis por la técnica bola de nieve. Resultados: El sistema de producción de café que predominó fue el sistema rústico de montaña, intercalado con plátano y frutales. La máxima productividad de las plantaciones se alcanza de 5.5 a 7.5años de edad, la renovación de plantas la hacen a los 12 años. El rendimiento de café fue de 3.7 kg por planta por año. La producción del café la realizan principalmente hombres (77.3%), entre 56 y 70años de edad. La venta se realiza en la presentación de café capulín a granel a intermediarios, a la ARIC, a CAFECO, a la Unión de Ejidos y a la Organización Mixtrui.Limitaciones del estudio/implicaciones: Se da una propuesta de mejora para favorecer el proceso de producción, beneficio y comercialización del café.Hallazgos/conclusiones: Coffea arabica es el principal café que se cultiva, con las variedades Typica, Caturra, Mundo Novo, Garnica y Bourbón. Los factores que limitan su producción y calidad son faltade planeación en manejo del cultivo y no contar con asesoría técnica.

Boro Rice

Utilization of urea super granule (USG) with raised bed cultivation system for transplanted boro (winter, irrigated) rice production is a major concern now days. A field experiment was conducted in the chuadanga district of Bangladesh to compare the two cultivation methods: deep placement of USG on raised bed with boro rice, and prilled urea (PU) broadcasting in conventional planting. Results showed that USG in raised bed planting increased grain yields of transplanted boro rice by up to 18.18% over PU in conventional planting. Deep placement of USG in raised bed planting increased the number of panicle m-2, number of grains panicle-1 and 1000-grains weight of boro rice than the PU in conventional planting. Better plant growth was observed by deep placement of USG in raised bed planting compared to PU in conventional planting. Sterility percentage and weed infestation were lower on USG in raised bed planting compared to the PU in conventional planting methods. Forty seven percent irrigation water and application time could be saved by USG in raised bed planting than PU in conventional planting. Deep placement of USG in bed saved N fertilizer consumption over conventional planting. Water use efficiency for grain and biomass production was higher with deep placement of USG in bed planting than the PU broadcasting in conventional planting methods. Similarly, agronomic efficiency of N fertilizer by USG in bed planting was significantly higher than the PU broadcasting in conventional planting. This study concluded that deep placement of USG in raised bed planting for transplanted boro rice is a new approach to achieve fertilizer and water use efficiency as well as higher yield and less water input compared to existing agronomic practices in Bangladesh.

Black Gram

Abstract A laboratory experiment regarding germination and seedling growth test was conducted with three black gram genotypes tested under three salinity levels (0, 75 and 150 mM), for 10 days, in sand culture within small plastic pot, to investigate the germination and seedling growth characteristics. Different germination traits of all black gram genotypes, like germination percentage (GP), germination rate (GR), coefficient of velocity of germination (CVG) greatly reduced, as well as mean germination time (MGT) increased with increasing salt stress. At high salt stress, BARI Mash-3 provided the highest GP reduction (28.58%), while the lowest was recorded (15.79% to control) in BARI Mash-1. Salinity have the negative impact on shoot and root lengths, fresh and dry weights. The highest (50.32% to control) and lowest reduction (36.39%) of shoot length were recorded in BARI Mash-2 and BARI Mash-1, respectively, under 150 mM NaCl saline conditions. There were significant reduction of root lengths, root fresh and dry weight, shoot length, shoot fresh and dry weight in all genotypes under saline condition. The genotypes were arranged as BARI Mash-1 > BARI Mash-3 > BARI Mash-2, with respect to salinity tolerance.
