Effect of Mulch and Mixed Cropping Grass - Legume at Saline Soil on Growth, Forage Yield and Nutritional Quality of Guinea Grass

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengkaji pengaruh dosis mulsa dan sistem tanam rumput dan legum pada tanah salin terhadap pertumbuhan, produksi hijauan dan kualitas rumput benggala. Tanah salin pada percobaan ini diklasifikasikan dalam tanah sangat salin dengan kesuburan tanah yang rendah. Rancangan percobaan adalah rancangan acak kelompok dengan 3 kelompok. Perlakuan adalah penanaman rumput benggala : M1 = monokultur, tanpa mulsa, M2 = monokultur, mulsa 3 ton/ha, M3 = monokultur, mulsa 6 ton/ha, M4 = tumpangsari dengan legum turi, tanpa mulsa, M5 = tumpangsari dengan turi, mulsa 3 ton/ha, M6 = tumpangsari dengan turi, mulsa 6 ton/ha. Data yang diperoleh diolah dengan analisis ragam dilanjutkan dengan uji wilayah berganda Duncan. Kadar air tanah tertinggi ditemukan pada perlakuan tumpang sari rumput dan legum dengan mulsa 6 ton/ha. Pertumbuhan, produksi dan kualitas hijauan rumput benggala tertinggi pada perlakuan dengan mulsa. Aplikasi mulsa 3 ton/ha pada tanah salin sudah meningkatkan pertumbuhan, produksi dan kualitas hijauan rumput benggala. Tumpangsari rumput dan turi tidak mempengaruhi pertumbuhan, produksi dan kualitas hijauan rumput benggala pada tanah salin.Kata kunci : mulsa, produksi, rumput benggala, tanah salin, tumpangsari ABSTRACTThe research was conducted to evaluate the effect of mulch and mixed cropping grass -legume at saline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in this research was classified into strongly saline soil with low soil fertility. The research was arrranged in randomized complete block design with 3 blocks. The treatments were : M1 = guinea grass monoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grass monoculture, 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 with Sesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed by Duncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegume with 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 plant growth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritional quality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Management Practices and Bioproductivity in Grassland of Dry Areas

“…In this regard, the addition of stubble on the soil surface favorably affects greater biomass production in grasses [44]. Other authors [45] obtained significantly higher increases in forage yield in guinea grass by adding straw to the soil. On the other hand, the hydrogel has shown a more efficient use of water, which improves the growth of plants [46], although this effect was not observed at the time of evaluation.…”

Salinization Process and Influencing Factors in Western Jilin Province, China

“…The natural water content, salt content were tested in laboratory of soil samples to investigate the water and salt migration law of saline soil of western Jilin, then the environmental factors of the study area have also been investigated to analysis the salinization process. According to earlier studies, the salinization of western Jilin was due to the strong evaporation effect of the earth's surface (Chen, 2013;Kusmiyati, 2014;Wang et al, 2015). The evaporation effect is influenced by natural facotors such as temperture and rainfall, so this study choose 3 environment factors as temperture, precipitation and evaporation to discusse the salinaztion process.…”
