Abstract

The research was conducted to evaluate the effect of mulch and mixed cropping grass – legume atsaline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in thisresearch was classified into strongly saline soil with low soil fertility. The research was arrranged inrandomized complete block design with 3 blocks. The treatments were : M1 = guinea grassmonoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grassmonoculture, 6 ton/ha mulch, M4 = mixed cropping grass with Sesbania grandiflora, without mulch;M5 = mixed cropping grass with Sesbania grandiflora, 3 ton/ha mulch; M6 = mixed cropping grass withSesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed byDuncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegumewith 6 ton/ha of mulch. The effect of mulch at saline soil significantly increased plant growth,forage yield and nutritional quality of guinea grass. Application of 3 ton/ha mulch increased plantgrowth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritionalquality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Abstract

The objective of this study was to evaluate the effectiveness of phosphate rocks (PRs) fertilizercompared to chemical P fertilizer for the best crop production and macronutrients of alfalfa. Acompletely randomized design under 3x3 factorial patterns was used in this research. The first factorwas different sources of P fertilizer: Guizhou Phosphate Rock (GPR), Jingxiang Phosphate Rock (JPR),and Single Super Phosphate (SSP). The second factor was level of P fertilizer: 75, 100, and 125 mgP2O5/kg soil. A control treatment (without addition of P fertilizer, CK) was added as a comparison withthe treatments. The results showed that JPR was the best for alfalfa production, whereas GPR and SSPwere better for nutrient content in the alfalfa tissue than JPR. On the whole, phosphate rocks had similareffect on alfalfa growth compared to SSP at the experimental conditions.

Abstract

Objective of the study was to identify all kinds of fungi which can life in the alfalfa plantation inBaturaden Purwokerto-Central Java. Fungi used in this study was 38 isolates. All fungi have been takenfrom the isolation of soil and root of diseased plant. Macroscopic and microscopic methods were usedfor identification. Potato Dextrose Agar (PDA) medium was used to grow the fungi. All fungi wereidentified using book identification of fungi. The results showed that from 38 isolates, six species wasdetermined and one was unidentifed. Those species identified were Cuninghammela sp, Trichoderma sp,Vertilicium sp, Eupenicillium sp, Pythium sp, Aspergillus sp.
