Abstract

Utilization of acidic marginal land for the cultivation of peanuts results in uneven yield productivity. Acidic soil is soil with a low base saturation level which affects the absorption of plant nutrients from the soil. This study aims to examine the effect of biochar and inoculation of soil-fertilizing microbes, Rhizobium sp. and arbuscular mycorrhizal fungi (AMF), also its interaction on groundnut production on acid soils. This experiment used a 4 × 3 factorial experiment with a completely randomized design (CRD) which was repeated 3 times. The first factor was the type of biochar material which consists of no application or control (B0), corn cobs (B1), rice husks (B2), and coconut shells (B3). The second factor was the inoculation of soil-fertilizing microbes consisting of Rhizobium sp. (M1), arbuscular mycorrhizal fungi (AMF) (M2), and the combination of Rhizobium sp. + AMF (M3). The results showed that the application of biochar was significantly different to plant height, while the inoculation of soil-fertilizing microbes was significantly different to the number of leaves. Both showed no significant difference in the total weight of pods, seeds, soil pH, and the proportion of CMA colonization. Treatment of biochar from rice husk and double inoculation of Rhizobium sp. + CMA significantly obtains the highest yield in effective root nodule production.

Abstract

Increased productivity of soybean (Glycine max L. Merrill) can be done through balanced and integrated fertilization. Rock phosphate and guano are natural sources of phosphor as an alternative to TSP fertilizer which has the advantage of not having a residual effect. The solubility of phosphor in natural phosphate is slow to be available. CMA inoculation can be done as an effort to increase the solubility of phosphor nutrients in natural phosphate. The aim of this study was to examine the response of soybean growth and yield due to CMA inoculation and natural phosphate fertilization, namely rock phosphate and guano. The research was conducted in January 2022 – April 2022 at the Greenhouse of the Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The study design used a monofactor completely randomized design (CRD) with the treatments being natural phosphate fertilization and CMA inoculation with 6 treatment levels (T1:TSP; T2:BP; T3:Guano; T4:TSP+CMA; T5:BP+CMA; T6:Guano+CMA). The treatment was repeated 8 times, so that 48 experimental units were obtained. The treatment was repeated 8 times, so that 48 experimental units were obtained. The research variables included plant height, number of trifoliate leaves, flowering age, dry weight of straw, number of filled pods, and dry weight of seeds. The data were analyzed by analysis of variance, then if it had a significant effect, it was continued with Duncan's multiple distance test (DMRT) at 5% level. The results showed that CMA inoculation treatment and natural phosphate fertilization could increase plant height, number of leaves, number of filled pods, and dry weight of seeds.Keyword: guano, mycorrhizal,  phosphate, soybean

Abstract

This study aims to examine the response of growth and production of sweet corn plants in application of organic and inorganic fertilizers. The research was conducted on July - October 2019 in Merbuh Village, Singorojo Sub-District, Kendal District and at Ecology and Plant Production Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang. The study used a randomized block design with 7 monofactor treatments with and each experimental unit was repeated 4 times. The treatments consisted of inorganic fertilizer (P0), chicken manure+inorganic (P1), goat manure+inorganic (P2), cow manure+inorganic (P3), chicken manure ‘plus’ (P4), goat manure ‘plus’ (P5), cow manure ‘plus’ (P6). Data were analyzed by variance and for treatments that showed signoficant differences further tests were carried out using DMRT at the 5% level. The observed variables were plant height, number of leaves, stalk diameter, cob production with cornhusk, and cob production without cornhusk. The results showed that the application of organic and inorganic fertilizers only affected stalk diameter. Stalk diameter in cow manure+inorganic gave the highest results compared to other treatments. There is  no influence on variables observed shows that the addition of gamal leaves as a source of N-organic and phosphate rock (BP) as P-organic in manure plus (chicken, goat, cow) can be an alternative solution to substitute inorganic fertilizers (urea and TSP) on sweet corn plant.

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

This research aims to examine the effect of application bamboo root PGPR and rice straw compost on the physical quality of the soil, growth and production of the corn plant (Zea mays). This research was arranged in split plot design 3 x 4 with 3 replications. The main plot is rice straw compost (K): K1=10 ton/ha, K2=15 ton/ha, K3=20 ton/ha. The subplot is PGPR (P): P0= 0 ml/l (control), P1=10 ml/l, P2=15 ml/l, P3=20 ml/l.  The parameters observed were soil porosity, soil water content, plant height, number of leaf, cob length, cob weight, weight of seed and field. Data were analyzed extensively and continued with Duncan Multiple Range Test (DMRT). The results showed that the treatment of PGPR and rice straw compost increases with the addition of dose. Treatment of PGPR provide a significant response to increase in the porosity, soil water content and number of leaf compared to the control, while the length of cob and weight of seed showed an increase in the addition treatment of a dose compost and PGPR. Treatment of PGPR or rice straw compost has yet to show a response different to the plant height. The interaction treatment significant on the weight of cob and field. The results of the optimal corn crop is achieved at the treatment dose of 15 ton/ha compost straw combined with PGPR dose of 15 ml/l.
