Abstract

The improvement of edamame soybean on peat soil is done by applying PGPR bamboo root and KNO3 fertilization. The purpose of the study was to determine the effect of the interaction between bamboo root PGPR concentration and KNO3 dosage and to determine the best concentration of bamboo root PGPR and KNO3 dosage on the yield and growth of edamame soybean plants on peat soil. This study uses a Factorial Complete Randomized Design (CRD) consisting of 2 treatment factors repeated 3 times. The first factor is PGPR bamboo root (P) consisting of 3 levels (p1 = 15 ml/L, p2 = 20 ml/L, p3 = 25 ml/L) and KNO3 fertilizer (K) consisting of 3 levels (k1 = 500 kg/ha equivalent to 2.5 g/plant, k2 = 600 kg/ha equivalent to 3 g/plant, k3 = 700 kg/ha equivalent to 3.5 g/plant). Based on the results showed that there was an interaction between the application of PGPR and KNO3 fertilizer on the growth and yield of edamame soybean on peatland and the interaction between PGPR concentration of 20 ml/L and KNO3 fertilizer dose of 500 kg/ha equivalent to 2.5 g/plant is an effective dose to increase the growth and yield of edamame soybean on peat soil.

Abstract

The Cauliflower (Brassica oleraceae var botrytis L.) is a potential horticultural commodity that has great prospects for intensive development in the lowlands. The vitamin and fiber content in cauliflower is so abundant that it is very good for the human body. Cauliflowers can be cultivated on several types of mineral soil, one of which is acid sulfate mineral soil. Problems in acid sulfate mineral soils contain high clay, high soil acidity, a pyrite layer, and nutrient deficiencies. Efforts can be made to support the growth of cauliflower by applying a soil saturated culture system, providing combination of goat manure + bioboost + dolomite, and using lowland cauliflower varieties. The research location is at Golden River Camp Kalimas Village, Sungai Kakap District, Kubu Raya Regency. The research took place from July to November, 2023. The research design used was a Split Block Design, consisting of 2 treatment factors and repeated 3 times and consisting of 4 sample plants. The first factor is the variety as the main plot with 2 treatment levels (Larissa and Snow White) and the second factor is the combination of ts (goat manure ton/ha + bioboost ml/l + dolomite ton/ha) as a subplot with 4 treatment levels. The variables observed in this study consisted of the number of leaves (strands), leaf area (cm2), fresh weight of upper plants (g), dry weight of upper plants (g), age of flower appearance (hst), crop diameter (g) and crop weight (g). The results showed that there was a different response between the two varieties and the combination of goat manure + bioboost + dolomite on the growth and yield of cauliflower, The Larissa variety showed better growth and yield when compared to the Snow white variety and the combination of goat manure 10 tons/ha + bioboost 15 ml/l + dolomite 2 tons/ha can increase the growth and yield of cauliflower better than other ts combinations on tidal acid sulphate soil with soil  saturated culture system.

Abstract

Scallions ( Allium fistulosum L.) are a horticultural crop commodity that is worthy of intensive development in Indonesia, especially in Pontianak, West Kalimantan Province. Peat soil has great potential for the development and cultivation of spring onions. Efforts that can be made to overcome the very low availability of nutrients are cow manure. One cultivation technique that can be used to increase leek production is by adjusting plant spacing. This research was carried out on research land located on Jalan Sungai Raya Dalam, Alam Mulia Housing Complex starting on 15 September – 2 November 2023. This research aims to obtain the best dose of cow manure for the growth and yield of leek plants on peat soil and to obtain the best planting distance for the growth and yield of leek plants on peat soil. This research was carried out using a field experimental method with a Split Plot Design pattern , namely: The first factor is the distance between the plants for the main plot: j 1 = 20 cm x 20 cm, j 2 = 20 cm x 25 cm and j 3 = 20 cm x 30 cm. The second factor is cow manure as a sub plot: p 1 = 10 tonnes/ha, p 2 = 20 tonnes/ha and p 3 = 30 tonnes/ha. The observation variables consist of: Root Volume, Plant Dry Weight, Number of Leaves/clump, Plant Height, Number of Saplings/clump and Fresh Weight of the plant. From research that has been carried out, the interaction of using a planting distance of 20 x 25 cm and 10 tonnes/ha of cow manure shows the best growth and yield of leek plants on peat soil.

Abstract

The productivity of sweet corn in the community is still low, this is due to factors limiting growth, one of which is soil fertility. The way to overcome peat soil problems is to use inorganic fertilizer accompanied by the application of biological fertilizer. The aim of the research is to determine the interaction of the use of inorganic fertilizers and biological fertilizers on nutrient availability and the growth of sweet corn on peatlands and to obtain the best dose of inorganic fertilizers and biological fertilizers. The research was carried out at a location located on Jln. Agreed 2, Gang Racana UNTAN, Southeast Pontianak District. This research was conducted June 14 – August 28 2023. Research using a Factorial Randomized Group Design (RAK) field experiment with 2 treatment factors with 3 replications. The first factor is Inorganic Fertilizer (A) consisting of 3 treatment levels, namely: a1 = recommended dose; a2= 75% recommended dose; and a3 = 50% of the recommended dose. The second factor is the dose of Sinar Bio biofertilizer (P) consisting of 3 treatment levels, namely p1= 45 kg/ha ≈ 1.00 g/plant; p2= 60 kg/ha ≈ 1.33 g/plant; and p3= 75 kg/ha ≈1.67 g/plant. The variables observed were nutrient availability, plant height, number of leaves, root volume, plant dry weight, harvest index, total leaf area. The research results showed that nutrient availability after incubation on the research land included very low to high criteria. There is an interaction between inorganic fertilizer and biological fertilizer on the growth of Sweet Corn on Peatlands, and the interaction of inorganic fertilizer at 75% of the recommended dose is equivalent to (Urea 4.21 g/plant, SP-36 2.11 g/plant, KCL 1.41) g/plant and biofertilizer at a dose of 60 kg/ha equivalent to 1.33 g/plant can increase the growth of sweet corn on peatlands. Keywords: Peat, Nutrient Availability, Growth, Inorganic Fertilizer, Biological Fertilizer  INTISARIProduktivitas jagung manis di masyarakat masih rendah, hal ini disebabkan adanya faktor pembatas pertumbuhan salah satunya kesuburan tanah.
