Azotobacter chroococcum based biofertilizers have been widely used in the production of environmentally agriculture. For commercial scale, cheap growth media for Azotobcter inoculant  will affect the quality and price of liquid biofertilizer. Growth medium should support cell proliferation as well as its  nitrogen fixation and phytohormone production.  The objective of this study was to determine whether  liquid organic fertilizer (LOF) containing low N can be used as a medium for scaling up  A. chroococcum inoculant without lowering the survival of bacteria and its activity in N2 fixation and phytohormones production. LOF generally contains a complete nutrient although in a small quantities. Experiment was set up in completely randomized design which tested two types of commercial LOF. The results showed that both of  LOF were only able to support cell growth up to 72 hours and at 96 hours cell viability began to decline compared to the control medium,  free-N Ashby. At 72 hour total N and cytokinin  concentration in LOF was lower than those in Ashby media. This study revealed  that LOF  could be used as A. chroococcum growth media, but without optimization of its composition, cell density and cytokinin content would be lower than those of inoculant  in Ashby Media.

Slow-release and organic fertilizers are promising alternatives to conventional fertilizers, as both reduce losses by leaching, volatilization and problems of toxicity and/or salinity to plants. The objective of this work was to evaluate the effect of different rates of the organic fertilizer Humato-Macota® compared with the slow-release fertilizer Osmocote® on the growth and nitrogen content in the dry matter of Rangpur lime. A field experiment was conducted in a factorial completely randomized design with an additional treatment (4 x 4 +1). The first factor consisted of four HumatoMacota® rates (0, 1, 2, and 3%) applied to the substrate; the second factor consisted of the same Humato-Macota® concentrations, but applied as fortnightly foliar sprays; the additional treatment consisted of application of 5 kgm-3 Osmocote® 18-05-09. Means of all growth characteristics (plant height, total dry matter, root/shoot ratio and leaf area) and the potential quantum yield of photosystem II (Fv/Fm) were higher when plants were fertilized with the slow-release fertilizer. The organic fertilizer applied alone did not meet the N requirement of Rangpur lime.

Distribution of salinity and sodicity through the world is around 80 thousand million km2. To this quantity, we must add 10 million ha of irrigated lands that are abandoned each year due to such adverse effects on irrigation as salinity and/or alkalinity. Easily available substrates, such as glucose, increase the microbial activity to imprpove soils; for example, pH decreases because of a high production of some metabolites, such as carboxylic acids and hydro phenolics group. We carried out a study to evaluate the effect of glucose application on tomato plant (Lycopersicum esculentum Mill.) growth in saline soil. The experiment was done under greenhouse conditions. Soil samples were taken from 0–20-cm depth at the “El Chococo” ranch (lat. 18°47'N; long. 103°55'W). Treatments imposed were: 2% (T1), 4% (T2), and 6% (T3) glucose and a control without glucose (T0). Soil with treatments was incubated at ambient temperature for 40 days. Tomato seeds were germinated for 30 days and later transplanted to plastic bags that contained treatments. After transplant, tomato plants were grown for 40 days and then evaluated for plant height, dry and fresh weight, aerial and radicular biomass, and foliar area. Treatments were distributed under randomized design, and Tukey's (0.05) separation means were done. When the glucose percentage was increased, the soil pH decreased 8.50, 8.0, 7.70, and 7.60 in T0, T1, T2, and T3, respectively, but electrical conductivity increased. The highest values of parameters evaluated in plants were measured in treatment T3, and all the plants died in treatment (0).

Cyperus rotundus L. and Ageratum conyzoides L. are commonly found in tomato field as weeds species. Weed compete with the crop for nutrient, water and light. In addition, weed released allelopathy that inhibited the growth of crop. The aim of this study was to compare the ability of allelopathy from C. rotundus L. and Ageratum conyzoides L. root extract to inhibit tomato plant growth. The study was conducted in Completey Randomized Design with two factors. The first factor was root extract from either C. rotundus L. and A. conyzoides L. as allelopathy. The second factor was concentration of root extract from both weeds (100, 300 and 500 g/ml). Each treatment combination was repeated four times. The results showed that A. conyzoides L. root extract had higher inhibition to growth of tomato plant than C. rotundus L. root extract. Increasing root extract concentration from both weeds increased inhibition of tomato plant growth.
