VEGETATIVE GROWTH OF CASSAVA (Manihot esculenta Crantz.) ON THE LIQUID ORGANIC FERTILIZER OF LEGUMINOSAE SPECIES AND CONCENTRATION

Cassava is one of the food crops with continous increasing demand. This study aimed to investigate the response of vegetative cassava growth to the application of different concentrations and types of liquid organic fertilizers (LOF) from Leguminosae plants. The research was conducted from February 27 to June 27, 2022, in Kembanglimus Village, Borobudur District, and arranged factorially (4x3) using a Randomized  Completely Block (RCB). The first factor was the type of liquid organic fertilizer derived from Leucaena leucocephala, Mimosa pudica, and Arachis hypogaea. The second factor was the concentration of LOF, consisting of 0 mL/L, 15 mL/L, 30 mL/L, and 45 mL/L. Chlorophyll content was analyzed using spectrophotometer and protein contet of leaf and tuber were analyzed with Kjeldahl methods. The results demonstrated that type of LOI did not have a significant effect on all parameters. Liquid organic fertilizer from Leguminosae plants with 0 mL/L  concentration resulted in the highest number of roots. Type of liquid organic fertilizer from Leucaena leaf with a concentration of 24.95 mL/L gave the highest number of roots, while type of LOF of Mimosa pudica with a  concentration of 26.31 mL/L gave the highest number of branches. Type of liquid organic fertilizer of Arachis hypogaea with a  concentration of 45 mL/L resulted in the highest total chlorophyll content, leaf protein content, and protein content in the tubersCassava is one of the food crops with continous increasing demand.

GROWTH AND YIELD OF ONION (Allium Cepa fa.ascolanicum) PHILIPINES VARIETY ON APPLICATIONS MYCORRHIZAL AND ORGANIC FERTILIZER IN THE LAND POST MERAPI ERUPTION

Research on agricultural land after the eruption of merapi aims to determine the impact of the effect of  mycorrhizal and organic material to the growth and yield of onion. The experiment was conducted in greenhouse Department of Agriculture, Government of Municipality Magelang, with a factorial experiment arranged in a complete randomized block design, with two treatment factors and repeated three times. The first factor is the treatment of a mixture of organic material and mycorrhizal: cocopeat 20 t/ha+mycorrhizal (10 g/planting hole), husk charcoal 20 t/ha+mycorrhizal (10 g/planting hole) and peat 20 t/ha+mycorrhizal (10 g/planting hole). The second factor is the dose of silty soil consists of four levels: 0, 2.5, 5 and 7.5 t/ha (%). The results showed that the kind of organic material and mycorrhizal added on cocopeat, husk charcoal and peat has not been able to influence the number of leaves, number of tubers per hill, the dry weight of the top of the plant, the dry weight of the roots of plants, dried tubers per hill, and the crop growth rate, The addition of clay soil which increased 7.5% on a sand media merapi eruption is able to increase the dry weight of the top of the plant, and the crop growth rate

PENGARUH JUMLAH DAUN DAN MACAM MEDIA TANAM PADA PERTUMBUHAN STEK JERUK NIPIS (Citrus aurantifolia Swingle)

A research on the effect of the number of leaves on cuttings and kinds planting media on the growth of lime (Citrus aurantifolia Swingle), conducted in July to November 2014.The research location is at Kaliboto Village, District Bener, Purworejo. The altitude is150, the soil is regosol soil and soil pH is 6.0. The method used is a factorial experiment (3x4) arranged in complete randomized block design with 3 replications. The first factor is the number of leaf on cuttings 0, 2, 4 leaves. The second factor is planting media: soil; soil added cocopeat; soil added husk; soil added cow manure (1: 1). The analysis showedcuttingswithtwoleavesare able to providethe highest parameter son shoots length, number of leaves, root length, buds fresh weight, buds dry weight, root fresh weight and dry weight of root cuttings. Media of soil added husk isable to increase shoots length, number of leaves, buds fresh weight, bud dry weight, root fresh weight and dry weight of root cuttings. The different number of leaves on different kinds planting media indicate different growthon all parameters observed exceptroot length

PENGARUH MACAM LANJARAN DAN MULSA PADA HASIL MENTIMUN VAR. ORIS (Cucumis sativus, L.)

A study on the effects of plant support and mulch on the yield plant of cucumber (Cucumis sativus, L.) var. oris was conducted in March - June 2015. The research was in Kembangkuning Village, District Windusari, Magelang. The altitude is 640 m, the soil type is latosol and soil pH is 6.5. The research is factorial (2 x 4) experiment arranged in a complete randomized block design with three replications. The first factor is kind plant support: bamboo and plastic net. The second factor is kinds of mulch, rice straw, black plastic, silveric black plastic and transparent plastic mulch. Plant support from bamboo may increase crop growt that cause higher the weight per fruit and fruit volume. Black plastic mulch and silveric black plastic mulch may increase plant height, leaf number, weight of the fruit, weight per fruit and fruit volume. The highest fruit volume is obtained from the growth of cucumber supported by plastic net on black plastic mulch and silveric black plastic mulch

UPAYA PENINGKATAN KUANTITAS DAUN MURBEI (Morus alba) DENGAN MACAM PUPUK NITROGEN DAN TINGGI PEMANGKASAN

Research on efforts to increase the quantity of leaves of mulberry (Morus alba) with a wide high-nitrogen fertilizer and pruning was conducted in August and October 2015. The research location PPUS Candiroto KBM Agroforestry Perum Perhutani Unit I Central Java, in the district of Temanggung. Altitude of 600 m above the surface laut.Jenis latosol soil with a pH of 6. The research was conducted using a split plot experiment (3x3) are arranged in a complete randomized block design, repeated three times. The first factor is kind of Phonska nitrogen fertilizer, Urea and ZA. The second factor is high trimming 40, 60 and 80 cm from the ground. The results showed that fertilization using nitrogen fertilizers can promote the growth of ZA shoot length, shoot number, leaf number, stem diameter shoots, shoots fresh weight and dry weight of shoots on mulberry plants. High-trimming 60 cm of the soil surface increases the best results in the long shoots, shoot number, leaf number, stem diameter shoots, fresh weight tu-nas, and dry weight of shoots on mulberry plants
