Abstract

This study aimed to examine the changes in the chemical properties of dryland Entisols upon the application of liquid organic fertilizer (LOF) from tofu waste and biochar, especially the content of C-organic, total N, total P, and P2O5 (available P), and the yield of pak choi. This study used a completely randomized factorial design. The first factor was the dose of tofu waste LOF (100, 200, and 300 ml/L water) and the second factor was the type of biochar (soil+rice husk biochar, soil+sawdust biochar, soil+rice husk biochar+ sawdust biochar). The combination of tofu waste LOF (100 ml/L) and the mixture of rice husk biochar and sawdust biochar (1:1:1) resulted in the most significant increase in C-organic (7.37%), total N (0.61%), total P (178.01 mg/100 g), and P2O5 (157.23 ppm) compared to other treatments. However, at a high dose of tofu waste LOF (300 ml/L of water), the contents of C-organic, total N, total P, and P2O5 tended to decrease, presumably due to the low pH of the tofu waste LOF. In terms of plant parameters, rice husk biochar treatment was the best for increasing the fresh weight of the shoots. This indicates that the optimal combination of LOF and biochar improved the chemical properties of Entisol analyzed after harvesting but did not increase the yield of pak choi at the beginning of application. However, rice husk biochar alone provided the best results for pak choi as an indicator plant. Keywords: C-organic, nitrogen, phosphorus, soil fertility, Timor

Abstract

This study aims to test the size of biochar particles in capillary irrigation media and the height of planting holes in a vertical culture system on the growth and yield of lettuce (Lactuca sativa L.) in dry land using the Split Plot Design (RPT) factorial method with 3 replications. The first factor is the size of biochar particles consisting of three levels, namely: unsieved biochar, finely sieved biochar <0.5 mm, and the remainder of the sieve> 0.5 mm. The second factor is the height of the vertical culture consisting of three levels, namely: 25 cm, 75 cm, 125 cm from the ground surface. The results showed that the treatment of biochar particle size in capillary irrigation media that was able to increase lettuce growth and production was finely sieved biochar <0.5 mm, namely in the observation of plant height at the age of 14 MST, 21 MST, 28 MST and the root crown ratio. The treatment of planting hole height in the vertical culture system that is able to increase lettuce growth and production is the treatment of planting hole height of 25 cm which gives the best results for plant height at the age of 21 MST, 28 MST and root crown ratio.

Abstract

This study aims to examine the production of bok choy in dry land due to differences in N fertilizer with planting media and row intervals through vertical fertigation cultivation. This study used a Split Plot Design with two factors, namely fertilizer with media and planting rows. The main plot was a combination of fertilizer and media consisting of: urea 1 g/L + POC 40 mL/L + BPN 10 mL/L with a planting medium of 50% soil: biochar - compost 50%; urea 0.5 g/L + POC 20 mL/L + BPN 5 mL/L with a planting medium of 50% soil: biochar - compost 50%; urea 1 g/L + POC 40 mL/L + BPN 10 mL/L with a planting medium of 25% soil: biochar - compost 75%; Urea 0.5 g/L + 20 mL/L Organic Fertilizer (POC) + 5 mL/L Organic Plant Growth Regulator (BPN) with a growing medium of 25% soil: biochar - 75% compost. The planting rows consisted of the first planting row, the second planting row, and the third planting row. The results showed that different N fertilizers, planting medium, and row intervals increased bok choy production in dryland, with the best results being achieved with urea 1 g/L + 40 mL/L Organic Fertilizer (POC) + 10 mL/L Organic Plant Growth Regulator (BPN) and 25% soil + 75% biochar - compost in the third row.

Abstract

Budaya tebas bakar merupakan praktik tradisional pengolahan lahan pertanian di daerah lahan kering dengan penebangan pohon dan pembakaran lahan untuk budidaya tanaman pertanian. Namun, praktik ini telah menyebabkan degradasi lingkungan dan penurunan produktivitas pertanian karena tanah menjadi tidak subur akibat kehilangan lapisan humus tanah dan nutrisi bagi tanaman. Upaya untuk mengatasi dampak negatif ini melalui edukasi masyarakat dan program pembibitan pohon untuk revegetasi lahan. Tujuan kegiatan PKM adalah untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam upaya mengendalikan pertanian tebas bakar di Desa Amol. Metode yang digunakan dalam kegiatan PKM adalah Focus Group Discussion (FGD), praktek pembibitan pohon. Hasil kegiatan PKM menunjukkan bahwa budaya tebas bakar berdampak negatif terhadap lingkungan, namun dengan adopsi sistem agroforestry dapat menjaga keberlanjutan lingkungan dan meningkatkan produksi pertanian. Upaya pelestarian lingkungan melalui edukasi, sosialisasi, dan demonstrasi pembibitan tanaman hutan menjadi langkah awal yang penting dalam menjaga lingkungan, meningkatkan produksi dan produktivitas, serta memberikan contoh bagi desa-desa lain dalam pelestarian lingkungan.

Abstract

Agricultural cultivation activities in Sekon Village are limited by soil conditions and water availability which then affects soil fertility and plant growth. Horticultural plants cultivated by the community have yellow-brown leaves, small leaf and stem sizes and stunted growth. Soil conservation strategy that can be implemented in this condition is the use of natural fertilizer (organic material). Meanwhile, water conservation efforts to overcome low water availability can be carried out by regulating watering through the application of a drip irrigation system. This research is a qualitative descriptive study which aims to identify the availability of Ca, Mg, K, Na and KTK in planting media samples after application of biochar compost and cow manure as well as implementation of watering regulations. The results of laboratory analysis show the average contents of Ca, Mg, K and Na respectively, namely 25.59 me 100 g soil-1 (very high), 2.66 me 100 g soil-1 (high), 0.96 me 100 g soil-1 (high) and 0.16 me 100 g soil-1 (low). The average KTK is 38.02 me 100 g soil-1 and is classified as high.Key-words: cations, planting media, soil and water conservationINTISARIKegiatan budidaya pertanian di Desa Sekon dibatasi dengan kondisi tanah dan ketersediaan air yang kemudian mempengaruhi kesuburan tanah serta pertumbuhan tanaman.

Abstract

The purpose of this study was to determine the effect of N fertilizer and ameliorant types on the growth, yield, and nitrogen absorption of pak choy (Brassica rapa L.) plants through wick fertigation systems in vertical cultivation in dry land. The research method used a split-plot design. The main plot is N fertilizer consisting of BPN + Urea, BPN + POC, and BPN + Urea + POC. The subplots are ameliorant types consisting of soil, soil: biochar (1:1), and soil: compost (1:1), which were repeated 3 times so that 27 total experimental combinations were obtained. The results showed that there was an interaction between N fertilizer and ameliorant types that could increase the growth and production of pak choy plants, where the interaction of BPN + Urea + POC treatment with ameliorant types of soil: biochar (1:1) gave the best results in observing the stem diameter and root length of pak choy plants. N fertilizer was able to increase the growth and production of pak choy plants, where BPN + POC gave the best results in observing the dry weight of the crown and N absorption of pak choy plants. The type of ameliorant is able to increase the growth and production of pak choi plants where the soil:compost (1:1) treatment gives the best results in observing plant height and the number of pak choi leaves.

Abstract

− Application of organic matter could be considered as an approach to improve productivity of saline soil. Local organic matter sources that were potentially applied including rice husk and cow manure. A glass house study aimed to investigate the effect of rice husk ash and cow manure doses on soil salinity and yield of baby bean crops had been done. The experiment was a factorial trial with two factors. The first factor was dosage of rice husk ash (A) with 4 levels, namely A0 (Without rice husk ash), A1 (20 tones rice husk ash.ha-1), A2 (40 tonnesrice husk ash.ha-1), A3 (60 tonesrice husk ash.ha-1), whilst the second factor was dosage of cow manure(S) consisted of 3 levels, namely S0 (without cow manure fertilizer), S1 (20 tonescow manure fertilizer.ha-1), S2 (40 tones cow manure fertilizer.ha-1).Variables observed were salinity (EC), Na, PNT, pH, and pod fresh weight. The results showed that although there was no interaction between rice husk ash dose and cow manure fertilizer dose, the single factor of rice husk ash dose significantly affected entire variables observed. The single factor of cow manure fertilizer, on the other hand, only affected soil salinity and PNT. Single treatmentof 300 g rice husk ash.polybag-1 reduced the soil salinity from the highest value of 4.35 mmhos.cm-1 to 0.83 mmhos.cm-1, and gave the highest baby bean pod fresh weight of 24,73 g.

Abstract

Pakcoy (Brassica rapa L.) is a green vegetable plant that is in great demand by people from children to adults, because it has very high nutritional value. Cultivation of pak choy plants on dry land with a dry climate requires the adoption of technology such as wick fertigation in verticulture. The aim of this research was to determine the effect of providing nitrogen fertilizer sources and types of ameliorant on the growth and yield as well as nitrogen uptake of pak choy (Brassicca rapa L.) plants. This research method uses a split plot design (RPT) with 2 factors consisting of a main plot and a subplot. The main plot is N fertilizer consisting of urea, POC, and urea + POC. Subplots are ameliorants consisting of soil, soil: biochar (1:1), soil: compost (1:1) and soil: biochar: compost (1:1:1). Thus, 12 treatment combinations were obtained which were repeated 3 times, resulting in a total of 36 experimental combinations. The research results showed that the interaction of the N fertilizer source and the type of ameliorant had a real influence on the observation of stem diameter and root length with the best treatment of urea+POC with the type of soil ameliorant: biocar: compost (1:1:1). The source of N fertilizer has a significant effect on shoot dry weight, harvest index and N uptake, where the best treatment is urea+POC fertilizer. The type of ameliorant had a significant effect on the number of leaves at 28 DAT and N content where the best treatment was soil: biochar: compost (1:1:1) showing the highest results when observing the number of leaves at 28 DAP and N content. Treatment of the type of soil ameliorant: biochar: compost (1:1:1) shows the best results.
