Abstract

Produksi kailan setiap tahunnya mengalami fluktuasi, diikuti dengan kesadaran masyarakat untuk mengkonsumsi sayuran semakin tinggi menjadikan produktivitas kailan masih rendah. Melalui pengaplikasian pupuk nitrogen dan nanosilika dapat memberikan peningkatan produksi pada tanaman kailan. Penelitian ini bertujuan untuk mengkaji pengaruh dosis nitrogen dan nanosilika terhadap pertumbuhan dan produksi tanaman kailan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor dan 3 ulangan. Faktor pertama yaitu dosis nitrogen meliputi B1 : 60 kg N/ha, B2 : 70 kg N/ha, B3 : 80 kg N/ha dan B4 : 90 kg N/ha dan faktor kedua yaitu dosis nanosilika, meliputi S1 : 0 ml SiO2, S2 : 60 ml SiO2, S3 : 70 ml SiO2 dan S4 : 80 ml SiO2. Parameter yang diamati yaitu tinggi tanaman, jumlah daun, berat segar, berat konsumsi dan panjang akar. Data yang diperoleh dianalisis secara statistik menggunakan sidik ragam 5 % dilanjutkan dengan uji Beda Nyata Jujur (BNJ) taraf 5% dan uji polinomial ortogonal. Hasil penelitian menunjukkan perlakuan nitrogen berpengaruh pada parameter tinggi tanaman, jumlah daun, berat segar total, berat konsumsi dan panjang akar, sedangkan aplikasi nanosililka memberikan pengaruh terhadap parameter tinggi tanaman, jumlah daun, berat segar dan berat konsumsi. namun terdapat interaksi terhadap tinggi tanaman, berat segar dan berat konsumsi.

Abstract

This research aimed to assess the effect of Naphthalene Acetic Acid (NAA) and nitrogen fertilizer on the growth of sugarcane (Saccharum officinarum L.) bud chips. The research was conducted using a 4 x 4 factorial design with the basis of a completely randomized design (CRD) of 3 replications. The first factor was the concentration of NAA which consisted of 0 ppm (without NAA), 50 ppm, 100 ppm, and 150 ppm. The second factor was the dose of nitrogen fertilizer which consisted of a dose of 45 kgN/ha, 90 kg N/ha, 135 kg N/ha, and 180 kg N/ha. The growth parameters observed included plant height, number of leaves, tillers, root dry weight, and shoot dry weight. The data were analyzed by analysis of variance and continued with Duncan’s test (Duncan’s Multiple Range Test) at a 5% level. The results showed that the application of NAA could not increase the growth of sugarcane bud chips on all parameters. Application of nitrogen fertilizer at a dose of 45 kg N/ha could increase plant height growth, number of leaves, root dry weight, and shoot dry weight. Nitrogen fertilizer with a dose of 180 kg N/ha reduced the growth of sugarcane bud chips. The higher dose of nitrogen fertilizer inhibited the growth of sugarcane bud chips.

Abstract

One of phosphate (P) fertilizer i.e. SP-36 is expensive and can be obtained by rock phosphate (RP). Rock phosphate combined with Vesicular Arbuscular Mycorrhizal fungus (VAM) could increase Pavailability. VAM consists of many species, so it is necessary to test the role of VAM species on cherry tomato plant. This study aims to examine the effect of VAM species and phosphate fertilization to improve cherry tomato production. The research use a Completely Randomized Design (CRD) which consisted of two factors with three replications. The first factor is the phosphate fertilization (P0= without P fertilizer, P1= SP-36, P2= rock phosphate) and the second factor is VAM species (M0= control without mycorrhizae, M1= Glomus etunicatum, M2= Glomus fasciculatum, M3= double inoculation of G. etunicatum and G. fasciculatum). The results show that mycorrhizae inoculation increases plant height, fruit number, fruit weight and accelerates flowering age compared to without inoculation. BP fertilization increases fruit weight. BP+CMA produces number of fruit equivalent to SP-36+CMA. BP+G. etunicatum treatment significantly increases fruit weight compared to SP-36+G. etunicatum. G. etunicatum inoculation gives the highest fruit weight compared to other inoculation.

Abstract

Pakcoy is a viable horticultural plant. High consumer demand, but the national pakcoy production is still low. This study aimed to examine the effect of various compost doses and PGPR doses on the growth and yield of pakcoy plants. This study used a 5x4 factorial RAL with 3 replications. The first factor is compost dosage (K) consisting of K0 = 0 kgN/ha compost, K1 = 138 kgN/ha compost, K2 = 69 kgN/ha compost, and K3 = 138 kgN/ha compost, K4 = 207 kgN/ha compost. The second factor is the PGPR dose (P) consisting of P0 = 0 ml/l water, P1 = 5 ml/l water, P2 = 10 ml/l water, and P3 = 15 ml/l water. The results showed that offering compost as much as 207 kgN/ha increased the growth and yield of pakcoy plants compared to giving 138 kgN/ha of inorganic fertilizer. The increase in the PGPR dose that was applied 2 times at planting and 14 days after planting (DAT) of 200 ml did not significantly increase the growth and yield of pakcoy plants.

Abstract

(Test of Association Selected Rhizobium Bacteria with Legumes in Salinity Stress) ABSTRACT. The research aim was to investigate association selected rhizobium bacteria with legumes in salinity stress. Plant media was salin soil that have EC = 20.45 mmhos/cm which taken from Morosari beach, Sayung, Demak. Rhizobium isolate applied was tolerant to 12.000 ppm of NaCl that equaled to electrical conductivity of 20 mmhos/cm. The research was carried out in green house of Laboratory of Forage Science Diponegoro University Semarang. The design arranged was completely randomized design with factorial design 2 x 4 in 3 repeatations. First factor was kind of legumes, T1 = lamtoro (Leucaena leucocephala); T2 = turi (Sesbania grandiflora). and second factor was kind of rhizobium isolates, I1 = without isolate; I2 = rhizobium that was isolated from lamtoro, I3 = rhizobium that was isolated from turi; I4 = combination isolate from lamtoro and turi. The crop growth was observed up to 10 weeks of age. The parameters were 1) crops heigh; 2) sum of leaf crops; 3) fresh weight production; 4) dry weight production; 5) amount and fresh weigh of effective root nodules. The study showed the growth and production of turi in saline media of EC 20.45 mmhos/cm was higher than lamtoro. Root nodule of turi was formed, but lamtoro was not. Turi was more tolerant than lamtoro at very saline media.

Abstract

The growth and production of hydroponic water spinach using liquid organic fertilizer and appropriate planting media determines the success of the plant. The aim of this research is to determine the effect of liquid organic fertilizer (LOF) substitution types and planting media on the growth of water spinach (Ipomoea reptans) production. Data collection was carried out in the month 23 Februaty – 30 March 2023 in Pudakpayung village, Banyumanik District, Semarang City. Treatments were arranged using a completely randomized design with 2 factors. Factor 1 is the planting medium in 2 level, M1 = Rockwool dan M2 = Cocopeat, and factor 2 is the substitution of liquid organic fertilizer in 4 levels, N1 = 4 ml/l AB mix, N2 = 3 ml/l AB mix + 2 ml/l POC, N3 = 2 ml/l AB mix + 3 ml/l POC, dan N4 = 4 ml/l POC. Each treatment was carried out in 3 repetitions so that there were 24 experimental units. The parameters observed were plant height, number of leaves, root length, shoot fresh weight, root weight, biomass weight, and leaf color. The data was analyzed for variance and further tested using the honest real difference (BNJ) at the 5% level. The research results showed that the use of LOF of rice waste and papaya fruit could substitute AB mix at a concertation of 2 ml/l AB mix + 3 ml/l LOF or 50%. However, the use of 100% POC cannot replace AB mix in growth and production of water spinach. Keywords : AB mix, cocopeat, liquid fertilizer, rockwool, rice, papaya fruit, waste
