Abstract

Objective of the research was to study the effect mycorrhiza on growth and yield of tomato. The experiment was conducted in screen house 14 m x 10.5 m, in Pasuruan on November 2013 until March 2014, The experiment was conducted as a factorial randomized complete design. The first factor was dose of mycorrhiza (without mycorrhiza, 5 g mycorrhiza, 10 g mycorrhiza, and 20 g mycorrhiza). The second factor was the salinity stress level (without NaCl, 2500 ppm NaCl, 5000 ppm NaCl, and 7500 ppm NaCl). The results showed that salinity stress at the level 7500 ppm decreased the amount of fruit by 30.84% and fresh weight per hectare decreased by 51.72%. Mycorrhizal application was not able to increase the growth and yield in saline stress conditions; it was shown by the level of infection and the number of spores on the roots of tomato plants lower the salinity level 5000 ppm and 7500 ppm. But separately, application of 20 g mycorrhiza enhanced plant growth, such as plant height, leaf area, leaf number and proline. Application of 20 g mycorrhiza increased the yield by 35.99%

Abstract

The aim of this research was to study the influence of P. fluorescens and sulfur on nutrients uptake, growth and yield of groundnut in alkaline soil. The experiment was conducted in the greenhouse in Malang from January 2015 to Mei 2015. The experiment was laid out in factorial randomized block design consisted of two treatment factors and three replications. The first factor were concentration of P. fluorescens (0 cfu/mL; 107 cfu/mL; and 109 cfu/mL). The second factor were elemental sulfur doses (0 g/kg soil; 1 g/kg soil; 2 /kg soil; and 3 g/kg soil). Soil used was collected from Lamongan East Java, Indonesia. Soil previously was given 40 g Ca(OH)2 /kg soil to achieve pH >8. There was no interaction between P. fluorescens and sulfur on all of parameters observed. P. fluorescens concentration of 109 cfu/mL independently significantly increased availabe Fe in soil as 34.75% compared with the control and could maintain the populations of P. fluorescens better than the concentrations of 0 and 107 cfu/mL. Sulfur significantly correlated with decrease in soil pH expressed by equation y = -0,226x + 8.218. Sulfur independently significantly increased N, P, S, Ca and Mn uptake by plants. Sulfur dose of 3 g/kg of soil provided leaves and stems growth better, increased 80.74% of pod yield and 34.09% of harvest index compared to control.

Abstract

Humic acid is believed to maintain the stability of the soil reaction, adsorption / fixation / cationic chelate, thereby increasing the availability of water and plant nutrients. On the other hand, the dynamics of saline soil cation is strongly influenced by the change of seasons that disrupt water and nutrient uptake of plants. This experiment was aimed to examine the characteristics of the humic acid from compost, coal, and peat and its function in the adsorption of cations (K+ and NH4+), thus increasing the availability of nutrients and growth of maize. The treatments tested were combination of three sources of humic acid (compost, peat and coal), two types of cation additives (K+ and NH4+), and three doses of humic acid-based buffer: 10, 20, and 30 g / 3kg. The treatments were evaluated against changes in pH, EC, cation exchange, chlorophyll content, plant dry weight and plant height. The experimental results showed that the addition of K+ and NH4+ affected the value of pH, CEC, K+, NH4+ and water content of the buffer. Application of humic acid-based buffer significantly affected exchangeable Na and exchangeable K. Humic pH dropped from > 7 to about 6.3, EC soil was about 0.9 mS / cm, exchangeable Ca, exchangeable Mg, exchangeable Na, and exchangeable K, respectively, were around 15.57-20:21; 1.76-6.52; 0.40-0.56 and 0.05-0.51 me / 100g soil. Plant growth (plant height, chlorophyll content, leaf area, and stem weight) at 35 days after planting increased with increasing dose of humic acid. The dose of 20g peat humic acid + NH4+ or 30g peat humic acid + K+ per 3 kg of saline soil gave the best results compared to the growth of maize from other treatments.

Abstract

Marine mud and manure are potential for improving ultisol conditions, especially soil acidity, CEC, base saturation, organic acid, soil structure, soil nutrient retention, aeration, soil humidity, water holding capacity, infiltration, and supply of phosphorus for plant growth and development. Two treatments, namely planting media with 200 t marine mud /ha + 30 t manure / ha, and 400 t marine mud /ha + 30 t manure / ha were able to increase pH from 4.6 to 5.6. A significant decrease of exchangeable Alsolubility of about 0.03 meq/100 g was found in M1O3; M2O1; M2O3 and M3O1 treatments. An increase of available phosphorus about 5.02 mg/kg was found at 200 t marine mud/ha + 30 t manure/ha treatment. There was a significant increase in plant height of about 62.42 cm in the media without marine mud and 30 t manure/ha. Application of 30 t manure/ hayielded plant with leaf size of about 9552 cm2 /plantand fresh fruit of about 9.81 t/ha.

Abstract

Microbial decomposers are living things posessing an important role in outlining materials derived from organic compounds entering the environment as plant nutrients so that they arereusable by the greenery. This study was aimed to isolate and identify types of microbial decomposers from Palu local cow manure of Central Sulawesi, Indonesia. The results showed that in Palu local cow manure there were three types of microbial decomposers namely Lactobacillus sp, Actinomycetessp and Aspergillus sp. In Actinomycetes sp., the colony growth was very slow and firmly attached to the media surface after incubated for 7 days. It showed formation of mycelium spreading on the media surface with a serrated edge. Aspergillus sp.had morphological characteristics formed on media as follows: green-yellowcolonies; like-furtextures; green conidia; radiatconidia arrangement, uniseriat, fialidwhich almostfilled the entiresurface of vesicles; like-ballroundvesicle; coarse, thick-walled, and dark greenconidiophores.
