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.
