Abstract

The silt pit is a method of soil management that functions to accommodate and absorb surface runoff. The research aimed to determine the silt pit effectiveness for erosion reduction and nutrient loss. The research is located at 576 above sea level (asl) in Sukamantri village, Taman Sari district, Bogor Regency. The experiment used a randomized block design with three replications and a slope group. The treatments were R0 (without silt pit); R1 (silt pit); R2 (silt pit + mulch); R3 (silt pit + mulch + biopore tube), R4 (silt pit + mulch + biopore tube + vertical crop tube). The highest runoff-decreasing occurred on R4 treatment, which pressed down 29.38% runoff. The highest value of erosion-decreasing occurred on R2 as 68.74% and followed by effectiveness in reducing the loss of 71% Organic C, 76% available P, and 67% total N. The dry seeds peanut yield was around 0.54 - 0.86 Mg ha-1, dried pods was 0.96 - 1.33 Mg ha-1, and dried biomass was 5.16 - 6.23 Mg ha-1 and not significantly different between all treatments. This study recommends that farmers apply silt pit innovation technology with a combination of mulch, biopore, and mature green media because the incremental B/C ratio was 1.175. It is a good economic indicator for farmers.

Abstract

Determination of the soil type had a significant effect on production. Therefore, type of selection and cropping land is factor that must be considered properly. This study aims to determine the level of nutrition fertility such as nutrient content found in several types of soil in Bogor regency. The types that will be analyzed are Andosol Soil, Latosol Soil, and Podsolic Soil. The parameters analyzed were water content, pH, organic carbon, total Nitrogen, available content of P2O5, potential content of P2O5, potential content of K2O, cation exchange capacity, exchangeable cation, exchangeable acidity, and 3 fraction textures. The results of the analysis showed that the highest nutrient content in a row were Andosol soil, Latosol soil, and Podsolic soil. The nutrient content values ​​in Andosol soil have good content values ​​in the parameters of organic carbon, Nitrogen, available P2O5, potential P2O5, potential K2O, and Exchangeable Cations in the K+, Na+, and Mg++ values. Latosol soil has good content values ​​in the parameters of available P2O5, potential P2O5, potential K2O, and exchangeable cations in the K+ value. The content with good value found in Podzolic soil is only the P2O5 parameter available.   Keywords: Andosol, Latosol, Podsolic, soil fertility

Abstract

Trichoderma harzianum has the ability as a decomposer organism and biological agent to control germination diseases that usually attack red chili plants. This study aims to determine the effectiveness of organic fertilizer given by T. harzianum on the productivity of red chili plants. The study consisted of eight treatments with four replications, namely treatment P0 (control), P1 (soil media + T. harzianum), P2 (soil medium + goat manure), P3 (soil media + manure + T. harzianum), P4 (soil media + compost), P5 (soil media + compost + T. harzianum), P6 (soil media + cocopeat), P7 (soil media + cocopeat + T. harzianum). The experimental design used was a completely randomized design (CRD). Parameters observed were plant height, number of leaves, flowering time, number of fruits, fruit length and fruit weight. The results showed that the enrichment treatment of organic fertilizer using T. harzianum had a very significant effect on plant height and number of leaves. Treatment using T. harzianum affected the height of red chili plants at the age of 14, 21, 28, 35 and 42 days after planting (DAP). The number of leaves was significantly different at the age of 21, 28, 35, and 42 DAP. The application of T. harzianum in goat manure had a very significant effect on the number of fruits, fruit length, and fruit weight. The best treatment was P3 treatment, namely soil added with goat manure in a ratio of 2:1 and T. harzianum 12 g had a very significant effect on plants, number of leaves, number of fruits, fruit weight, and fruit length of red chilies.

Abstract

Fertilization is important in peanut cultivation through the use of fertilizers tailored to crop requirements. This study aimed to determine the effects of NPK fertilizer form and dosage on nutrient uptake and peanut yield. The experiment was arranged in a Randomized Block Design with a 2 × 2 factorial pattern and eight replications, resulting in 32 experimental units. The treatments consisted of two factors: the first was fertilizer form, with granular and blended options. The second factor was NPK fertilizer dosage, with two levels: 200 kg ha⁻¹ and 250 kg ha⁻¹. The results showed a significant interaction between fertilizer form and dosage on plant height at 25 days after planting and net pod weight. The highest plant height reached 14.8 cm in the blending form treatment and a dose of 250 kg ha-¹, while the best net pod weight was 2,681.8 kg ha⁻¹, obtained from blending fertilizer at a dosage of 200 kg ha⁻¹. In the blended fertilizer form, N and K nutrient uptake were higher than in the granular form. Uptake of P tended to be similar across both fertilizer forms and dosages. Fertilizer dosage significantly affected crop productivity, with the highest yield obtained at 250 kg ha⁻¹.
