Abstract

The fabrication industry plays a large role as a source of agricultural land pollution, especially in areas close to factories. Corn and rice plants are food crops that are needed by the community. Along with increasing environmental pollution, research is needed. The purpose of this study was to determine the effect of plant media contaminated with plant waste on the vegetative growth of corn and rice plants. The research was carried out in the greenhouse and laboratory of the Land Resources of the Faculty of Agriculture of the East Java National Veterans Development University. This research uses a completely randomized factorial design with 2 factors. The first factor is the type of plant which consists of 2 factors (corn plants and rice plants). The second factor is the type of media contaminated with factory waste consisting of 6 levels of treatment (paper mills, pharmaceutical factories, trias factories, leather factories, batik factories and garden lands). The results of the treatment were 12 treatment combinations with 3 replications and using the Least Significant Difference test (LSD) of 5%. The results showed that plant media contaminated with factory waste showed a real interaction with the length of the corn plant + paper factory, corn + pharmaceutical factory, corn + trias factory and corn + batric factory at the age of 4 HST. The types of corn plants respond better at the beginning of plant growth, plant length, number of leaves and root length. Rice types give a better response to the number of leaves, tillers, number of tillers and number of roots. The type of pharmaceutical planting media gives a better effect on the parameters of plant length and number of leaves.

Abstract

Sandy soils have high macropores and low nutrient availability. This condition is caused by the soil matrix which has no negative charge, so that nutrients are easily lost due to washing. Nitrogen loss has been reported to reduce rice production by 6.10%. The research aims to examine the application of humic acid and silica to increase the availability of nitrogen nutrients. Humic acid from compost and silica from rice husk is expected to increase the negative charge of the soil so that can adsorbnutrient ions such as nitrogen. The research was carried out from March to September 2021 in the greenhouse and laboratory of the Faculty of Agriculture, National Development University "Veteran" East Java. The research was structured using a factorial Completely Randomized Design (CRD). The first factor is silica dose with a level of 0 ton/ha, 0.5 ton/ha, 1 ton/ha, and 1.5 ton/ha. The second factor is the dose of humic acid with a level of 0 kg/ha, 20 kg/ha, 40 kg/ha, and 60 kg/ha. Observation parameters include the availability of N in the soil, the growth of rice plants which include plant length and the number of tillers. The results showed that the combination of humic acid and silica didn't significantly affect plant length and number of tillers, but had a significant effect on nitrogen availability. The best dose of the combination of silica with humic acid on nitrogen availability in sandy soils is S2H3 (Silica 1 ton/ha with humic acid 60 kg/ha).

Abstract

Multiplication of multiantagonist Trichoderma sp. and Streptomyces sp. done on agar plates and liquid media covered for multiplication and facilitate cell harvesting. Root suspension containing microorganisms and humic liquid is a biopesticide and fertilizer material that was expected to be more effective for biodegradation of biological agents to have more value. This study aims to determine the ability of life and propagation Trichoderma sp. and Streptomyces sp. in root suspension, humic liquid and sugar potato extract. This study used a descriptive observations on days 10th, 14th and 17th before inoculation of Trichoderma sp. and Streptomyces sp showed that in liquid humic medium there are microorganisms but fewer number of microorganisms on root suspension media. The 17th day after inoculation of the Trichoderma sp. and Streptomyces sp showed that in the humic liquid medium, the biological agent did not grow, while the root suspension medium was only Streptomyces growing but not as much as developed on sugar potato extract.

Abstract

The increasing population and the problem of land use change that continues to increase raises the problem of food security. Government programs have been carried out such as the expansion of marginal land in coastal areas, namely saline land. The research objective was to assess the effectiveness of P uptake due to the aplication of humic acid and silica on lowland rice crop production. The research method was arranged in a randomized block design that was repeated 3 times. Size of planting 2x2 m2, 4 kinds of treatment include; a. control b. humic acid c. silica d. humic acid + silica. The results showed that the application of humic acid + silica had a significant affect the rice growth with an average plant height of 85,74 cm at 10 mst and rice production of 4,20 ton.ha-1. Humic acid + silica can also improve soil chemical properties : pH 6,95 CEC 40,24 and P nutrient 197,6. This is because the ability of humic acid to chelate by removing the Pbonds from the uptake of metal and silica elements can increase the P content in the soil into a from that is more available to plants.

Abstract

The mineralization process is responsible for the availability of N in the soil. The purpose of this study is to examine the management of coffee land (Coffea L.) and climate on the rate of soil Nitrogen mineralization. In situ incubation research by implanting 15.5 cm long cylindrical pvc ring; diameter of 14 cm that has been perforated around it and a wire covering / net so that animals such as scorpions and snakes do not enter the hole. The research was arranged in factorial randomized block design which was repeated 3 times. Factor 1 : 3 types of land management and factor 2 : 4 types of organic matter. The level of N mineralization is evaluated against the levels of N-nitrate and N-ammonium soil. The highest NH4+ N concentration of 0.060% was found in the L1S3 treatment (first land, mixed ring) and the lowest NH4+ concentration in the L3S1 treatment (third land, control ring) 0.03%. NO3 concentration - interaction occurs with the highest NO3 concentration in the L2S3 treatment (second land, mixed ring) 0.092% and lowest NO3 concentration in the L1S1 treatment (first land, control ring) 0.013% with a BNT value of 5% at 0.023%. So the fastest nitrogen mineralization occurs in soils that get litter of shade plants (mixed / S3). The value of mineralization rate is strongly influenced by temperature, the increase in the value of mineralization rate due to temperature is due to the faster process of decomposition of organic matter.

Abstract

Changes in land use will impact on the characteristics of humic acid in the soil due to biotic and abiotic factors. The study aimed to characterize humic acid in soil from various land uses in Tutur District, Pasuruan Regency of East Java. Soil sampling was carried out on six land uses, namely mixed garden, coffee plantation, apple orchard, vegetable garden, pine forest, and conservation forest. Analysis of soil samples included soil chemical characteristics (pH, redox, organic-C, and total-N) and characterization of humic acid included colour ratio of E4/E6, total acidity, carboxyl groups, and phenolic groups. The results showed that the land use of coffee plantation provided the best soil fertility indicated by the contents of humic acid, total-N, organic-C in the soil that were higher than that of other land-uses. The highest humification index was obtained for coffee plantation land use with the measurement of the E4/E6 colour ratio of 4.56 index value. The best characteristics based on the total value of acidity, the -COOH group and the phenolic -OH group were observed in the coffee plantation. This was supported by the characteristic of humic acid through the humification index or E4/E6 colour ratio, as well as the low phenolic -OH value which is a characteristic of fulvic acid.

Abstract

Crop salt tolerance is generally assessed as the relative yield response to the increasing of  root zone salinity.  This paper studied the maize tolerance under salinine water  (ECw) and their relationship with the changes of soil chemistry characteristics, crop growth and yield of maize. The seven level of water salinity were  0.66, 0.93, 1.57, 1.68, 2.46, 3.35, 3.85 mS cm-1 and three local maize from Madura, Pasuruan and Probolinggo were evaluated to soil electric conductivity (ECe), pH, available -N. -P. and -K as well as plant height and seed weight  The experiment indicated that saline water (ECw) up to a certain concentration increased soil salinity (ECe) and pH, but decreased  nutrient availability, plant height, fresh and dry weight of  maizes.  ECw level between 1.5 to 1.7 mS cm-1 gave the best results compared to others, because of soil nutrients and water availability optimum. Maize of Madura and Pasuruan were more tolerant than Probolinggo  giving ECw up to 3. 85 mS cm-1, although their maize seed dry weight were lower.
