Conservation of Soil Moisture Using Mulch of Green Bean Plants (Vigna Radiata)

Abstract

The aim to this study was to determine the effect of plastic silver mulch and rice straw mulch on soil moisture conservation of green bean so that the plant can grow in dry season with enough water. The method used in this study was a randomized block design with three treatments: no mulch (T0), plastic silver mulch (T1) and rice straw mulch (T2). The parameters observed were physical soil of initial and final research, soil moisture measurements every 3 days, as well as growth and crop production parameters including plant height, number of seeds in pods, 100 seeds weight, sample plant production and total production. The results showed that the physical of soil analyzed were clay textured soil, preliminary porosity 60.77 and at the end of the study increased to 77.50%, organic matter 1.52%, initial bulk density 1.04 g/cm3 at the end of the study decreased to 0.60 g/cm3, soil permeability of 7.77 cm / hour and available water is 13.95%. The use of rice straw mulch from the beginning to the end of the study showed the best water content while the use of plastic silver mulch and no mulch showed water content not much different. The use of palstic silver mulch gives the highest yield of the best crops on 14 HST measurements where the plastic silver mulch differs markedly by the rice straw mulch and no mulch. The yield of green beans produced in the treatment of plastic silver mulch using the best results with a total production of 2.00 tons/ha, this result is significantly different from no mulch but not significantly different of rice straw mulch. Rice straw mulch is better used for soil conservation because it can improve soil aeration, retain water, prevent soil erosion, and increase organic matter on the soil.

Enhancing crop yield and conserving soil moisture through mulching practices in dryland agriculture

“…As an insulating layer, it controls soil temperature, reduces heat stress, and maintains consistent soil moisture levels. By reducing the rate at which water moves over the soil's surface, mulch also reduces runoff, which means that more water makes it to the root zone (Suburika et al, 2018). It prevents weeds from growing, which means less water is available for the roots and less watering is required.…”

PEMANFAATAN LIMBAH PERTANIAN SEBAGAI MULSA DAN KOMPOS DALAM PENINGKATAN PERTUMBUHAN DAN PRODUKSI TANAMAN KACANG TANAH (Arachis hypogaea L.)

“…Pemberian mulsa organik (sisa tanaman) dengan cara disebar dapat melindungi tanah dari panas yang berlebihan et al Mulsa dapat menurunkan suhu dan meningkatkan lengas tanah, sehingga ketersediaan air terjaga untuk pertumbuhan tanaman (Novriani et al 2018). Hal ini sesuai dengan pendapat (Suburika et al, 2018) pemberian mulsa dapat mempertahankan lengas tanah karena mampu menekan laju evaporasi dari dalam tanah Ketersediaan air yang terjaga akan meningkat juga meningkatkan dan mempertahankan kelembaban tanah sehingga aktivitas mikroorganisme dalam tanah dapat meningkat. Hal ini sesuai dengan pernyataan Brodhagen et al (2015) bahwa kelembaban tinggi pada media tanah dapat meningkatkan aktifitas mikroorganisme dan mikrofauna di dalam tanah seperti cacing tanah yang membuat lubang udara dan mempermudah ilfiltrasi air, dengan gemburnya tanah maka pertumbuhan tanaman meningkat.…”

“…Mulsa dapat digunakan untuk penutup tanah yang bertujuan untuk menjaga suhu tanah agar tetap stabil, menjaga kelembaban tanah, mencegah terjadinya erosi, meningkatkan kesuburan tanah dan mencegah pertumbuhan gulma. Suburika et al (2018) mengatakan konservasi tanah memakai mulsa jerami maupun plastik dapat melindungi tanah dari benturan hujan, mencegah erosi, mampu menahan air tanah, dan meningkatkan kadar bahan organik.…”
