Abstract

Pekarangan bagi penduduk di pedesaan selain berfungsi sebagai tempat bermukim juga berfungsi sebagai sumber pendapatan dan sumber gizi bagi keluarga. Pada lahan pekarangan ditanami berbagai macam tanaman hortikultura (mix cropping) yang dipadukan dengan usaha ternak dan pemeliharaan ikan, sehingga ditemukan berbagai pola dan intensitas pemanfaatan sesuai dengan luas lahan yang dimiliki. Penelitian ini telah dilaksanakan di desa Desa R Rejosari dan Desa P1 Mardiharjo, Kecamatan Purwodadi, Kabupaten Musi Rawas, pada bulan November 2010. Metode yang dilakukan adalah metode survei dan metode penarikan contoh yang digunakan adalah metode acak sederhana (simple random sampling). Hasil penelitian menunjukkan bahwa terdapat berbagai macam pola pemanfaatan lahan pekarangan pada kedua desa yang diteliti, dimana di desa R Rejosari terdapat 8 macam pola dan di desa P1 Mardiharjo terdapat 9 macam pola, yang didominasi tanaman buah-buahan (pisang, sawo dan rambutan). Intensitas pemanfaatan lahan di kedua desa tersebut tergolong masih rendah, karena banyak ditemukan lahan kosong atau tidak ditanami, sebagian tanaman masih muda dan kurang optimal pertumbuhannya, serta sebaran pohon yang tidak merata.

Abstract

This research aimed to determine the increase in green mustard growth on marginal land through the application of trichoderma sp biofertilizer. This research was carried out in Muara Enim Village, West Lubuklinggau I District, Lubuklinggau City from July to September 2024. This research used a non-factorial randomized block design with 6 levels of treatment, namely: T0: No application of biological fertilizer (control), T1: Application of biological fertilizer at a dose of 60 grams/polybag, T2: Application of biological fertilizer at a dose of 100 grams/polybag, P3: Application biofertilizer dose 140 grams/polybag, T4: Application of biofertilizer dose 180 grams/polybag, T5: Application of biofertilizer dose 220 grams/polybag. The research results showed that trichoderma sp biological fertilizer has a very real influence on the growth of mustard greens on marginal land. Providing trichoderma sp biological fertilizer at a dose of 220 grams/polybag was able to show the best results at plant height, namely 31.03 cm, number of leaves 16.50, leaf length 20.27 cm, leaf width 13.01 cm and root length 35 .91 cm. The application of trichoderma sp biological fertilizer is not only able to increase soil fertility but is also able to protect plants from soil pathogens. Keywords: Microorganisms, Pathogens, Trichoderma sp.

Abstract

Cocoa plants are plantation crops, one of the export commodities that can contribute to efforts to increase Indonesia’s foreign exchange. This research aims to determine the type of storage media, storage time and treatment interactions on the germination response of cocoa seeds. The research was carried out in Madang Village, Sumber Harta District, Musi Rawas Regency from February-March 2024. The research method used a Completely Randomized Factorial Design, the observation data was  analyzed using R-Studio software. If the results of the variance test are significant at the 5% level, mean that the treatment shows a significant or very significant effect, then it will be continued with high significancy different test (HSD). The first factor consists of the type of storage media: without treatment (M0), sawdust storage media (M1), wood charcoal powder storage media (M2), and rice husk storage media (M3), the second factor is length of storage time: without treatment (W0), stored for 5 days (W1), stored for 10 days (W2), stored for 15 days (W3) and repeated 3 times. Based on the results of the research, sawdust storage media treatment had a significant effect on: germination at age 1-10 days and 11-20 days, root length, leaf length and leaf area; without storage  treatment had a significant effect on: at age 1-10 days and 11-20 days, root length, leaf length, and leaf area.

Abstract

The efforts to develop and increase rice production in tidal land need appropriate technologies including adaptable superior varieties and efficient seed planting system. This study was aimed to measure the agronomic characteristic of the three rice varieties on the systems of in-row direct seeding and broadcast in tidal land. The experiment was carried out at type B of tidal land in Sidoharjo Village, Air Saleh Subdistrict, Banyuasin District, from January to April 2016. The experiment was conducted using split plot design with four replications. The main plot was seed planting system, consisted of in-row direct seeding system and broadcast system; whereas subplot was three rice varieties, consisted of  Inpari 22,  Inpara 4, and Ciherang.  Result of LSD test on interaction showed that though the best growth was obtained from the combination of Inpari 22 and in-row direct seeding and  very significant  with the others, but its yield was not significant with the combination of Inpara 4 and in-row direct seeding. It was concluded that Inpari 22 and Inpara 4 with in-row direct seeding system showed better growth and higher yield than Inpari 22, Inpara 4 and Ciherang with broadcast system in tidal lands. Ciherang was not suitable in tidal land, while Inpari 22 was suitable.

Abstract

This study aimed to determine the effect of manure type and KCl fertilizer dosage on the vegetative growth of sweet corn plants. The research was conducted in R Rejosari Village, Tugumulyo District, Musi Rawas Regency, from June to August 2024. This study used a Factorial Randomized Block Design (FRBD) consisting of 2 treatment factors and repeated 3 times. The observation data were analyzed using Analysis of Varians (ANOVA) using the R Studio program. f the results of the analysis of variance test are significantly tested at the 5% level, and if the results of the analysis of variance test are very significantly tested at 1%. then it will be continued with the honest significant difference test (HSD). The treatments that will be applied are as follows: The first treatment is the type of manure (M) which consists of 3 types of levels, namely: M1 = Cow Manure Dose 1 kg, M2 = Goat Manure Dose 1 kg, M3 = Chicken Manure Dose 1 kg. The dose of potassium fertilizer (M) consists of 3 types of levels, namely: P1 = Dose 5 g / polybag, P2 = Dose 7.5 g / polybag, P3 = Dose 10 g / polybag. Chicken manure has the best effect on plant height, number of leaves per plant, stem diameter, wet biomass weight, and dry biomass weight of plants

Abstract

Dry land has significant potential for cultivating hybrid corn. However, its limitations include water scarcity, poor soil physical properties, and limited availability of NPK nutrients. To improve dryland conditions, organic fertilizers, inorganic fertilizers, and organic fertilizers enriched with phosphate-solubilizing bacteria can be applied. The use of organic fertilizers—such as chicken manure and empty oil palm bunches (tankos)—as well as organic fertilizers enriched with phosphate-solubilizing bacteria, can enhance soil quality by improving its physical structure (making the soil looser and more fertile) and chemically increasing nutrient availability, thereby supporting better growth and yield of hybrid corn plants. This study aimed to evaluate the effectiveness of various fertilizer types on the growth and productivity of hybrid corn cultivated on dry land. The field experiment was arranged in a randomized complete block design (RCBD) with four treatments, each replicated six times: recommended chemical fertilizers (A), chicken manure fertilizer (B), organic fertilizer enriched with phosphate-solubilizing bacteria (C), and empty oil palm bunches (tankos) fertilizer (D). The highest yield was achieved using the recommended chemical fertilizer, producing 3.42 kg per plot (13.68 tons per hectare). The second highest yield was obtained with organic fertilizer enriched with phosphate-solubilizing bacteria, yielding 2.98 kg per plot (11.92 tons per hectare). The third-highest yield came from chicken manure fertilizer, producing 2.67 kg per plot (10.68 tons per hectare), followed by tankos fertilizer at 2.2 kg per plot (8.8 tons per hectare). The novel finding of this study is that organic fertilizer enriched with phosphate-solubilizing bacteria, without the addition of inorganic fertilizers, can achieve yields comparable to those obtained with recommended chemical fertilizers. While inorganic fertilizers are effective in increasing hybrid corn yields in the short term, their long-term use may negatively impact the environment and soil fertility. Therefore, organic fertilizer enriched with Azospirillum bacteria presents a more environmentally friendly and sustainable alternative.
