Kenaf Seed

An experiment was conducted at the Bangladesh Jute Research Institute (BJRI), Regional Station, Kishoreganj during July to December of 2010 and 2011 to investigate the effect of spacing and de-topping on yield and quality of kenaf seeds cv. HC-95 grown under direct seeding method. Three plants spacings (40 cm × 15 cm, 30 cm × 15 cm and 20 cm × 15 cm) and four de-topping treatments (no de-topping, de-topping at 15, 30 and 45  days after emergence (DAE) were applied in a Randomized Complete Block Design (RCBD) with three replications. The highest yield of kenaf seed (1403 and 1646 kgha-1 in 2010 and 2011, respectively) was obtained from sowing at 30 cm × 15 cm spacing. The best quality seed in respect to germination and vigour was also obtained from sowing at 30 cm × 15 cm spacing. The highest seed yield, germination and vigour of seed were obtained for de-topped at 45 days after emergence. It is concluded that the highest seed yield and quality of late season direct seeded kenaf could be obtained by sowing at a spacing of 30 cm x 15 cm and de-topping at 45 days after emergence.

Gate Operation

Subak had been known as superior and sustainable water management system in Bali’s paddy field, and had a long history as an interesting topic for study. Water management in Subak is more or less based on religious practices and the philosophy of the harmony among God, human and nature, that ensures equity and sufficiency of water diversion. Traditionally there is no water regulation in the meaning of gate operation as most Subak has their own water source from definite location, and fixed system was used for water diversion that defined portion of water discharge and not quantity. In this study, field monitoring system had been set up to continuously observe the water balance components such as: rainfall, evapotranspiration, percolation, field water status. With the available data, water balance equation can be used to obtain net inflow, which in this case only minimum, median and maximum for each particular month. These values were used to summarize total annual net inflow to the field, which ranges from 4575 to 7419 mm.  This is accounted as total water use for rice production at the site and generally it can be concluded as the amount of water required to sustain the present paddy field of the Subak.
