Abstract:
Abstract The VP3 biofertilizer formulation begins with exploration of indigenous soil bacteria isolated from several soil samples in Malang-Indonesia. The VP3 Biofertilizer is a liquid formulation made from vermiwash and molasses as carriers, with 3 functional bacterial isolates. It has been proven to be able to increase the yield of mung beans, long yard beans, and green beans in the green house, however it has not been applied to soybean (Glycine max L.) in the field compared to other biofertilizers on the market. This study used soybean seeds of the Anjasmoro variety and consisted of 6 treatments (different types of biofertilizer) with a Randomized Block Design (RBD) namely VP3 biofertilizer, EM4 biofertilizer, Sumber Subur biofertilizer, Semanggi biofertilizer, and Magicgro G6 biofertilizer. This research was carried out in idle land. The application of VP3 biofertilizer when compared to other biofertilizers on the market generally gave better results on the parameters of growth and yield of soybeans in the field. This is indicated by the significant yield on leaf area per plant and yield of total seed weight per plot of soybean plant.Keywords:

A field experiment was conducted at College Farm, Navsari Agricultural University, Navsari (Gujarat) during rabi season of the year 2017-18 to study the “Effect of fertilizer levels, biocompost and biofertilizer effect on yield and yield attributes of fodder sorghum. Twelve treatment combinations consisting of three levels of fertilizer, two levels of biocompost and two levels of biofertilizer were tried in factorial randomized block design with three replications. The result showed that among different treatment combinations, application of 100% RDF with biocompost and biofertilizer significantly registered maximum green and dry fodder yield, plant height and stem girth. While, in interaction maximumplant height, green and dry fodder yield was recorded in 100% RDF with biofertilizer which was statistically at par with 75% RDF with biofertilizer.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from February to June 2010 to study the effect of bio fertilizer and weeding on the growth characters and yield of summer mungbean (cv. Binamoog-7). Experimental treatments comprised of (a) five levels of biofertilizer: 0, 1, 2, 3, 4 kg ha-1 and (b) four levels of weeding: no weeding, one weeding, two weeding, and three weeding. The experiment was laid out in a randomized complete block design with three replications. The results indicate that the highest plant height (58.83cm) was obtained at 60DAS from 4 kg biofertilizer ha-1 and the highest dry weight plant-1 (17.78g) at 60DAS was produced from 2 kg biofertilizer ha-1.Three times weeding produced highest plant height (41.69cm) and dry weight plant-1 (18.09g) at 60DAS and seed yield (1.96 t ha-1) was attained significantly at maximum level from the application of 2 kg ha-1biofertilizer. Application of 2 kg biofertilizer ha-1 with three times weeding was proved to be the best possible combinationDOI: http://dx.doi.org/10.3329/jesnr.v7i1.22150 J. Environ.

Cucumber is a vegetable species of high socioeconomic importance, whose fruits are consumed in all Brazilian regions. However, the knowledge of its organic production is still incipient. In this perspective, this study aimed to evaluate the productive performance of the Aodai cucumber under organic cultivation in response to the application of biofertilizer via soil and leaves. The experiment was conducted in the Seridó Ecological Site, Rio Branco, AC, by adopting a randomized block design in a 6x2 factorial arrangement, with four replications and eight plants per experimental unit. The treatments consisted of six concentrations of biofertilizer (0, 1, 2, 3, 4, and 5%) diluted in water, applied via foliar spraying, combined with the presence or absence of its pure application in the soil, with both methods applied at 7, 14, 21, and 28 days after sowing. The fertilizer was also applied in the soil at sowing. At the end of each harvest, the fruits were divided into two quality categories (classes 1 and 2), and then the following variables were evaluated: number of fruits per plant, mean fruit mass, yield, fruit diameter, and fruit length. There was no significant interaction of the biofertilizer application via foliar spraying or soil for any of the variables. The biofertilizer application via foliar spraying promoted a significant increase in the number of marketable fruits per plant, mean mass of total fruits, and marketable and total yields. The 3% concentration of biofertilizer diluted in water and applied on the leaves is the most efficient method to increment the cucumber yield.

The adequate spacing in okra (Abelmoschus esculentus) influences its growth and fruit production. The objective of this study was to evaluate the growth, the leaf composition and okra production in different spacing with and without biofertilizer. This research was carried out from October, 2012 to March, 2013, at the Federal University of Paraiba, Areia county, Paraiba State, Brazil. The experimental design was a randomized complete block design with three replications, using the 3 × 4 × 2 factorial scheme, referring to three spacing between rows (0.80, 1.00 and 1.20 m), four spacing between plants (0.30, 0.40, 0.50 and 0.60 m), with and without bovine biofertilizer. The leaf area, mean fruit mass, number of plant-1 fruits, plant-1 fruit yield and N, P and K contents were significantly influenced by the spacing × biofertilizer interaction. The commercial productivity of the okra was altered only by the spacing. The application of biofertilizer at spacing of 1.00 × 0.50 m and 1.20 × 0.50 m increased the leaf area of ​​okra. The smaller spacing, associated with the presence of biofertilizer, increased the productive characteristics of okra. Key words: Organic input, population density, yield.

To study effect of biofertilizer and urea application on yield of Corn (Zea mays L.) a factorial experiment was conducted based on randomized complete block design. Treatments were urea rate (0, 30, 60, 90, 120 and 150 kg.ha ) and nitragin as a biofertilizer. When seeds inoculated with biofertilizer, leaf area index 1

A field experiment was conducted at College Farm, Navsari Agricultural University, Navsari (Gujarat) during rabi season of the year 2017-18 to study the “Effect of fertilizer levels, biocompost and biofertilizer effect on physico chemical properties of soil. Twelve treatment combinations consisting of three levels of fertilizer, two levels of biocompost and two levels of biofertilizer were tried in factorial randomized block design with three replications. The result revealed that application of different treatments did not affect the pH, EC, available K2O and micronutrients (Fe, Mn, Zn and Cu). While soil bulk density decreased, micro aggregate and organic carbon significantly improved after harvest of fodder sorghum. Available N of soil after harvest of fodder sorghum was improved significantly due to the integration of inorganic fertilizers with biocompost and biofertilizer. Available P2O5 content found non-significant but interaction of biocompost and biofertilizer found significant.
