Abstract

Bernas et al. 2012. Bamboo Floated-cultivation Model for Upland Kangkung (Ipomoea reptans Poir.)  in Tidal Lowland Area. JLSO 1(2):177-185. South Sumatra Province has a high potential of swampland for expansion of floating agriculture system. Swampland in Palembang, for instance, can be adapted for floating vegetable cultivation.  The experiments on floating agricultural system have been done by using wasted plastic glass, bamboo for rice and glutinous rice with the application of Hycinth and water Fern compost.  The purpose of this research was to build bamboo rafts which were suitable for growing kangkong (Ipomoea reptans).  Previous rafts which contained water saturated soil for rice growing needed to be adjusted for kankong cultivation which prefer unsaturated soil.  Two bamboo rafts were built using four plastic containers in bottom corners.The first raft was filled with soil plus compost (ratio 1:1) and the other was filled only with swamp soil.  Kankong seeds were planted with the distance of 25 cm by 25 cm.  Data were collected weekly and analysed statistically using t-test.  Results showed that when the rafts were supported by two bamboos, plants were died due to excessive water.  Plants grew well after the rafts were supported by plastic containers.   Composting significantly increased plant height, number of leaves, plants fresh and dried weight.  Plant height treated with compost was 38 cm compared to that without compost treatment which was 28 cm. Fresh plant weight was 149 g/bunch with compost treatment and 25 g/bunch without.  Thus, low fertility of swamp soil only required compost to increase nutrients content for plant growth.This research concluded that plant can be cultivated cheaply and environmentally safe in swampland.  Further experiments such as replacing plastic container in raft construction and growing other vegetables on the raft were proposed.

Abstract

Aksani, et al. Soil Bacteria Population in Paddy Tidal Land by Application of Liquid Fertilizer Neptunia prostrata. JLSO 5(2):170-177. High soil acidity in tidal lowland influences soil bacteria population. This research aimed to determine soil bacteria population with liquid fertilizer application made by Neptunia prostrata for paddy grown in tidal lowland. This research using factorial completely randomized design with two factors and three replications. The first factor was liquid fertilizer rate, consisting of three levels: 96 mL pot-1(P1), 120 mL pot-1(P2) and 144mL pot-1(P3). The second factor was application period consisting of three times: once time at the planting time (W1), two times at the planting time and harvesting time and three times at the planting time, primordial stage and harvesting time. The result showed that the highest soil bacteria population was 10,94 log spk g-1with the treatment of  144 mL pot-1 liquid fertilizer and given once time at the planting time (P1).

Abstract

Bernas SM, Fitriana M, Wijaya A, Fitri SNA. 2020. Effect of the seedling age and compost to the growth of palm date lulu (Phoenix Dactylifera L.) nursery and investigation of female seedling. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 199-207.Indonesia imported very high amount of date palm fruits about 9.99 million kg or US$ 13.18 M, because of that it is necessary to develop a research about date palm seedling nursery and investigation of female date, since this is a dioecious plant. The aim of this investigation was to find out characteristics of female date seedling and the effects of seedling age and compost on seedling growth. There were 2 steps in this research: the first was application of compost on seedling (without and plus compost treatments) and the age of seedling (15 and 30 days old) for transplanting into polybag, the growth ability of plant was monitored. The second step was transplanting seedling at 30 days old into pan for investigation female date, which 20 seedlings were planted in one pan and replicated 3 times.  Results showed that compost increased roots and leaves growth on seedling.  Transplanted at 30 days old seedling had the ability to grow about 95% compared to 15 days old was only 45%. It was found that female seedling was about 25% and the rest (75%) was male or sterile. It is needed further investigation on growing female seedling in the field and can it produce fruit.
