Abstract

One of the problems on soybean production in North Kalimantan is the acidic soil conditions. The use of soybean varieties that are resistant to acidic soil conditions is an alternative to overcome this problems. Dena 1 and Devon 1 soybeans were the varieties that can be grown in acid soils. In addition to the right seeds, application of fertilizer is also needed to support the growth and grain yield of soybean. This study aimed to determine the interaction between varieties with Urea dosage on growth and grain yield of soybean varieties Dena 1 and Devon 1. The experimental design of this study was factorial randomized block design with two factors. The first factor was the soybean variety which consisted of: V1 = Devon 1 and V2 = Dena 1. The second factor was the Urea fertilizer dosage which consisted of four levels: P0 = Control, P1 = 1.32 g/plant, P2 = 2.64 g/plant, P3 = 5.28 g/plant. The results showed that there were no interaction between varieties and the Urea fertilizer dosage on growth and grain yield of soybeans. However, the variety independently had a significant effect on plant height and leaf width, which was shown by the Dena1 (V2) treatment.

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

The effort to utilize the soils optimally, especially Ultisols, requires an appropriate understanding related to their characteristics. The characteristics of Ultisols are sturdily influenced by soil-forming factors, viz. climate, parent material, pedogenic age and topography. The purposes of this study were to determine the chemical, physical, mineralogical characteristics and soil development classification level of Ultisol from two different types of parent rock. This research was conducted in Kampungbaru Village, Petir District and Sukalaksana Village, Curug District, in Serang Regency, Banten Province. These two villages represented different parent materials, namely andesite lava parent material of Holocene age (Kampungbaru Village) and tuff dacite parent material of early Pleistocene age (Sukalaksana Village). The research method was descriptive, comparative and survey. Soil classification was based on the Soil Survey Staff. The results showed that Ultisols developed from dacite tuff and andesite lava did not show contrasting differences in soil properties. The level of weathering of the two pedons was at the senile stage and the level of soil development of the two pedons was at the argillic stage. The soil classification of Kampungbaru pedon was Typic Palehumults, very fine, kaolinitic, isohyperthermic, while the Sukalaksana pedons was Arenic Paleudults, fine, kaolinitic, isohyperthermic

Abstract

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, in order to fulfill the continuous increase, researches were conducted to increase land productivity. The increase of growth and productivity of upland rice with the application of Azospirillum sp. and Azotobacter sp. in compost, Azolla, and rice bran carrier were studied. Nitrogen fixer were applied as a biofertiliser as a mean to supply available nitrogen for upland rice growth. This research was conducted in Ciparanje Experimental Field and Soil Biology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. In this research, Randomized Block Design was used to analyze two factors: urea dose (100% and 50%) and Nfixer bacteria in various carriers (individual carrier and combination of liquid inoculant, green compost, Azolla compost, rice bran). The result showed an interaction between two factors towards the grain weight of upland rice. The application of 100% urea dose showed higher result compared to 50% urea dose on grain weight. N fixer bacteria combined with compost, Azolla, and rice bran carrier gave the highest result on the number of tillers, chlorophyll content, and grain weight.

Abstract

Sandy soils commonly have high macropores and low plant nutrient availability. This condition is caused by the soil matrix which has almost no negative charge, so there's no strong adsorption capacity for ions.  The next impact is that nutrients become easily lost because they're washed or evaporated. Nitrogen loss has been reported to reduce rice production by 6.10%. The research objective was to examine the effective application of humic acid and silica to improve the availability of nitrogen nutrients in sandy soil. Humic acid from compost and silica from husk charcoal is expected to increase the negative charge of the soil (cation exchange capacity) so that can adsorb and fixate nutrient ions such as nitrogen. The research was carried out from March 2021 to September 2021 in the greenhouse and land resource 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-1, 0.5 ton ha-1, 1 ton ha-1, and 1.5 ton ha-1.  The second factor is the dose of humic acid with a level of 0 kg ha-1, 20 kg ha-1, 40 kg ha-1, and 60 kg ha-1.  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 to plant. The best dose of the combination of silica with humic acid on nitrogen availability in sandy soils is S3H1 (Silica 1.5 ton/ha with humic acid 20 k.ha-1).

Abstract

Corn cultivation on Ultisols is limited due to low nitrogen content of the soil. Efforts to increase the N content in the soil include the use of biofertilizers by symbiotic nitrogen-fixing endophytic bacteria. This study assesed various combination of nitrogen fertilizer doses and N2-fixing endophytic biofertilizer to increase the growth of maize in Ultisols Kentrong. The experiment was conducted at the Ciparanje Experimental Greenhouse, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. A randomized block design was used which consisted of 16 treatments with 3 replications, with a combination of doses of urea fertilizer and endophytic biofertilizer applied to seeds or planting holes. The experimental results showed that the combination of urea fertilizer and biofertilizer doses had a significant effect on the population of endophytic bacteria in the roots and leaves of corn plants, plant wet weight, root dry weight and shoot dry weight, plant height, stem diameter, plant nitrogen uptake and content of plants but was not significantly affected on the number of corn leaves. Combination of 80 kg ha-1 urea fertilizer and 3.6 kg ha-1 of biofertilizer was the best combination which increased the dry weight of the corn plant and reduced the dose of urea fertilizer
