Abstract

Suwandi et al. 2012. Application of Extract Compost Increased Yield and Suppressed the Diseases of Ratoon Rice Crop in Tidal Swamp of Banyuasin Regency. JLSO 1(2):116-122.A field study was conducted to test the effects of the biofertilizer preparations on yield and diseases of ratoon rice crop in the reclaimed tidal swamp of Telang II, Banyuasin Regency of South Sumatra. The biofertilizer were prepared either as dormant inoculant in liquid formulation or active inoculant in compost extract. Both preparations contain chitinolytic, cellulolytic and phosphate solubilizing bacterial community. The result showed that the yield of ratoon crops of Ciherang rice variety in the suboptimal land increased by 67% (923 kg/Ha) in response to single spraying of the compost extract. The ratoon sprayed with the compost extract had a lower incidence of neck blast and panicle blight and produced less empty grains compared to non-sprayed control. The application of extract compost appears to be a feasible method for increasing production of ratoon rice in tidal swamps.

Abstract

Susilawati et al, 2017. The Growth and Yield of Cauliflowers (Brassica oleraceae var. Botrytis L.) on Planted Media of Aquatic Weeds Compost. JLSO 6(1):43-48.The objective of this research was to know the growth and yield of cauliflowers on various planted media organic of compost aquatic weeds. This research was conducted from November 2016 to Febuary 2017. The research was rendomized block design with ten treatments and three replications.  Each unit consisted of 3 plants, so there were 90 plants.  The treatments were B0: (soil 100%), Be1 (75% soil: 25% water hyacinth fertilizer), Be2 (50% soil: 50% water hyacinth fertilizer), Be3 (25% soil: 75% water hyacinth fertilizer), Bu1 (75% soil: 25% hymenachne compost), Bu2 (50% soil: 50% hymenachne compost), Bu3 (25% soil: 75% hymenachne compost), Bi1 (75% soil: 25% salvinia compost), Bi2 (50% soil: 50% salvinia compost), Bi3 (25% soil: 75% salvinia compost). The result showed that the treatment 75% soil and 25% salvinia compost gave the best effects on weight flowers, leaf number, weight of fresh roots and weight of dry roots.

Abstract

Lettuce (Lactuca sativa L.) was a leafy vegetable that has high economic value in Indonesia and provides health benefits to consumers. The use of organic fertilizers is deemed more optimal than inorganic fertilisers due to the potential of inorganic fertilizers to cause soil damage and environmental pollution through chemical residues and land productivity reduction. The study aimed to evaluate the effects of using NASA liquid organic fertilizer and cow manure on the growth and yield of lettuce plants. The study used a Randomised Block Factorial Design with two factors: cow manure with four treatment levels and NASA liquid organic fertiliser with three treatment levels. The results showed that chicken manure had a significant effect on plant height, leaf area, leaf dry weight, and stem fresh weight at 28 days after planting (DAT), while NASA liquid organic fertilizer had no significant effect on all parameters except plant height at 7 DAT. Higher doses of chicken manure (S2 and S3) contributed to the increase in dry weight and fresh weight of leaves. Application of NASA liquid organic fertilizer at a dose of 4 ml/L (N2) showed a better response in supporting plant vigor than others. In addition, the highest plant fresh weight was obtained in the combination of S3 and N2 treatments, indicating a synergistic effect between the two types of organic fertilizers. High a dose of chicken manure (S3 = 900 g) can negatively affect growth by lowering soil pH and causing too acidic conditions that are not optimal for plants.
