Clove oil has the potential to suppress the development of the mosaic virus in patchouli plants, but its effectiveness in the field has not been studied. This study aimed to evaluate the effect of clove nano biopesticide on controlling patchouli mosaic disease. The research was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. The patchouli used was Patchoulina-2 variety, which originated from the Seed Breeder Garden in Lembang, Bandung.  This study was arranged in a Randomized Block Design (RBD), consisting of five treatments and ten replications within each treatment, with one hundred plants in each replication. The results obtained showed that nano biopesticides of citronella, clove, and commercial citronella (Asimbo) were able to reduce the incidence and intensity of mosaic diseases in patchouli plants, showing the efficacy levels of 14.68%, 9.06%, and 5.83%, respectively. The application of citronella and clove biopesticides on Patchoulina-2 every month could increase plant fresh weight, when compared to the plants without treatment. Patchoulina-2 plants treated with nano biopesticides of clove and commercial citronella (Asimbo) showed higher value of fresh weight compared to those treated with citronella nano biopesticide. The clove nano biopesticide can also be developed to control mosaic diseases in patchouli plants.

Aims: This study investigated the use of agro-wastes for the production of briquettes. It was carried out to investigate the effect of formulation, binder and compaction pressure of rice husk-Bagasse briquettes on thermal and physical properties. Study Design: The experimental design for this study was 6x5x2 Randomized Complete Block Design Place and Duration of the Study: Rice husks and bagasse were collected from Lake Basin Development Authority’s rice mill and Kibos sugar and Allied company respectively. The binders were sourced locally in Kisumu. The study was conducted between March 2019 and February 2020. The fabrication and laboratory analysis were carried out in the engineering and laboratory departments of Kenya Industrial Research and Development institute, Kisumu. Methodology: The experimental design for this study was 6x5x2 Randomized Complete Block Design. This study involved six formulations ratios (0:100, 20:80, 40:60, 60:40, 80:20, 100:0), five compaction pressure levels (108kPa, 180kPa, 253kPa, 325kPa, 397kPa) and two binders (clay, cassava) They were arranged in Randomize Complete Block Design with three replications per experiment. Results: The briquettes bulk density was in the range of 849 to 1001 kg.m−3, while the calorific value ranged from 5.541 kcal/g for 100% Rice husk clay binder to 7.345 kcal/g 20% Rice Husk cassava binder. Briquettes with blend ratio of 40-60% Rice Husk took longer time to burn. Briquette formulations with clay binder had burning rates ranging from 0.28 g/min to 0.15 g/min while with cassava binder from 0.52 g/min to 0.37 g/min. The ignition time of the briquettes ranged from 62 sec to 95 sec with cassava binder and 110 sec to 191sec with clay binder. The shatter index ranged from 0.94 to 0.99 with cassava and 0.9 to 0.98 with clay binder. Conclusion: Higher compaction pressures and use of cassava binder produced stronger briquettes with higher calorific values. Briquettes with higher percentage of bagasse had low ignition time and low bulk densities. The bulk densities and ignition time showed significant rise with increase in the compaction pressure but inversely affected the burning rate. The binder used significantly affected both the thermal and physical properties of all the formulations.

Abstract Most potato farmers in Indonesia select the small tubers at harvest for planting in the following season, the so-called farmers’ practice (FP). This propagation method is cheap, but the small tubers may come from less healthy plants, which increases the build-up of diseases with accelerated yield decreases over the seasons. Alternatively, farmers may identify healthy plants within the growing season and select those for propagation, the so-called positive plant selection method (PPSM). An experiment was carried out to evaluate the effects of PPSM compared to FP on yields in the following season in the two main potato growing areas of West Java, i.e., Pangalengan and Garut. Generations G2 and G3 of cv. Granola and one generation of the imported cv. Atlantic were used. Selected seeds using PPSM and FP were planted in the second season in a randomized complete block design. Results show that yields of seeds selected through PPSM were significantly higher compared to seeds selected through FP, over both locations, on average, 7.4, 5.5 and 1.2 ton ha−1 for Granola G2 and G3, and the Atlantic, respectively. These yield increases represent an increase in the gross revenue of 30.8 to 51.8 million IDR ha−1 for Granola and 1.9 to 7.8 million IDR ha−1 for Atlantic at a farm gate price of 7,000 and 6,500 IDR kg−1, respectively. This study confirms that PPSM is superior to FP and improves the quality of the farms saved seeds.

Stimulants are one of the common ways to increase yield in rubber plants. Recent, the stimulant that is widely used in rubber tapping is ethephon. Ethephon material can prolong the flow of latex so that yield increases. The combination of osmolyte and alkaline compounds is expected to be an alternative stimulant. Therefore, this study aimed to examine the use of osmolytes and alkaline in rubber plants. This research was conducted at the Experimental Design of the Sungei Putih Estate Research, Deli Serdang, North Sumatra in May-September 2016 with PB 260 clones planting year 2010 with a tapping system S/2 D3 Ga1.0 6 / y (m) in panel B0-2. The experimental design used was a Randomized Complete Block Design (RCBD) with 28 combinations of treatments. The observation parameters in this study were yield (g/p/s), girth (cm) before treatment application and yield (g/p/s) and yield (kg/ha/year) after treatment application. The observations showed that the addition of stimulants with osmolyte and alkaline compounds had a significant effect yield on rubber (g/p/s) in the first tapping slices. The 5% osmolyte and 10% alkaline compounds have yield rubber which is comparable to the application of stimulants made from ethephon in the first tapping slices. Application of 5% osmolyte and 10% alkaline compounds can be used as an alternative stimulant in rubber plants.

An experiment was conducted at the Jute Research Regional Station, Kishoreganj of Bangladesh Jute Research Institute, during 2001-2002 and 2002-2003 to find out the effects of preceding crops, viz. wheat, potato, lentil, and fallow on yield of succeeding jute crops. The experiment was laid out in a randomized complete block design with four replications. The results revealed that plant height and base diameter of CVL-1 and O-9897 were not affected significantly by the preceding rabi crops. The fibre and stick yields of both the jute varieties were affected significantly. The highest fibre yield of CVL-1 (3.90 t ha-1 and 3.77 t ha-1) and O-9897 (3.51 t ha-1 and 2.93 t ha-1) was recorded when those were grown after potato and the yield was the lowest when grown after wheat and fallow land in both the years. There was no sharp variation in harvest index, which showed inconsistent between the years.Bangladesh Agron. J. 2014, 17(2): 15-19
