“…However, there was no difference in plant height between treatments 10 ton ha -1 , 20 ton ha -1 and 30 ton ha -1 . These results were in accordance with the previous studies that compost made from rice straw and cow dung [7] and the application of water hyacinth residue [8] into soil-rice systems had an effect on the appearance of rice. However, the amount of organic matter applied was not significantly different between treatments.…”

“…The implementation of OM as bio slurry on rice growth and production has been evaluated. Improving soil quality directly due to the application of OM was thought to affect the performance of agricultural soils in producing rice [7,8,9,10,11,12] . Superior varieties of rice (SVR) have many advantages over local varieties of rice (LVR), and vice versa.…”

“…Hyacinth compost remarkably improved the growth parameters in wheat crop (Widjajanto et al, 2001) and physicochemical properties and microbial activities in soil (Lata and Veenapani, 2011). Furthermore, being easily decomposable water hyacinth qualifies as a potential organic source for nutrient management which can also stimulate microbial activities (Balasubramanian et al, 2013).…”

A ny material (organic or inorganic), applied to soil to provide one or more essential plant nutrients is called fertilizer (Vidya and Lakshmi, 2014). Weeds are one of the overlooked natural resources that can support and help to reduce the use of chemical fertilizers. The addition of compost to salt-affected soil improved the soil properties including soil porosity water holding capacity, improved nutritional status, bulk density, soil pH s , EC e and SAR (Zaka et al., 2018;Wright et al., 2007).Aquatic weed, water hyacinth (Eichhornia crassipes) grows at an alarming rate and float freely on rivers, ponds, lakes etc. (Lata and Veenapani, 2011). Due to its harmful effects on people's livelihoods and water bodies, it is known as the most obnoxious weed in the world (Wilson et al., 2005;Singh and Bishnoi, 2013). Attempts made to control this weed through different means like biological, physical and chemicals have met with little success (Abdelsabour, 2010). Nonetheless, different researchers presented the idea to obtain the benefits from this aquatic weed rather than seeing it as a rogue plant (Anjanabha and Abstract | Composting the unwanted aquatic weeds for supply of essential plant nutrients and improving the health of salt-affected soil is a simpler technique. Therefore, present research work was carried out to appraise the efficacy of water hyacinth compost as an ameliorant for improving the deteriorated properties of saline-sodic soil. Treatments included were; T 1 , control, T 2 , gypsum @ 100 % GR, T 3 , gypsum @ 50 % of GR, T 4 , hyacinth compost @ 15 t ha -1 , T 5 , gypsum @ 50 % of GR + hyacinth compost @ 5 t ha -1 , T 6 , gypsum @ 50 % of GR + hyacinth compost @ 10 t ha -1 , T 7 , gypsum @ 50 % of GR + hyacinth compost @ 15 t ha -1 . At start of study, soil had pH s (pH of soil saturated past) = 8.91, SAR (sodium adsorption ratio) = 44.24, EC e (electrical conductivity of soil extract) = 5.02 (dS m -1 ), GR (gypsum requirement) = 10.18 (t ha -1 ), BD (bulk density) = 1.66 (Mg m -3 ), HC (hydraulic conductivity) = 0.35 (cm hr -1 ). Rice and wheat, crops were grown in the rotation. Data analysis showed that gypsum and hyacinth compost remarkably improved the soil SAR, pH s , EC e , BD, HC, growth and yield characteristics of rice and wheat crops, however at the same time use of gypsum and hyacinth compost in combination proved more superior to their sole application. Hyacinth compost @ 10 and 15 t ha -1 with gypsum @ 50 % of GR performed equally in all studied parameters of rice and wheat crops and soil properties. Therefore, integrated use of gypsum @ 50 % of GR + hyacinth compost @ 10 t ha -1 , seem as economical and a potential agro-ecological strategy for improving the deteriorated properties of saline-sodic soil and crop production.

“…Semakin meningkat takaran kompos didalam tanah menyebabkan peningkatan kation dapat dipertukarkan tanah PMK yang diperkirakan merupakan kontribusi dari dekomposisi kompos tersebut. Hal ini didukung oleh (Widjajanto et al, 2001) yang menyatakan bahwa bahan organik seperti limbah tanaman, pupuk hijau dan kotoran ternak dalam sistem tanah-tanaman dapat memperbaiki struktur tanah, membantu perkembangan mikro organisme tanah, dan sumber unsur hara. Selanjutnya (Hakim et al,1986) juga mengemukakan bahwa pemberian pupuk organik dapat meningkatkan daya larut unsur N, P, K, Ca dan Mg, meningkatkan C-organik, kapasitas tukar kation, kapasitas tanah memegang air, menurunkan kejenuhan Al dan bulk density (BD) tanah.…”

asalah utama yang dihadapi dalam pemanfaatan tanah Podsolik Merah Kuning (PMK) adalah rendahnya kandungan hara serta buruknya sifat fisika dan kimia tanahanya. Sifat kimia tanah PMK yang bermasalah diantaranya yaitu pH tanah masam, kandungan C-organik rendah, P tersedia rendah, KTK dan basa-basa dapat dipertukarkan (K, Ca, Mg, Na) yang rendah. Penelitian ini bertujuan untuk memperbaiki beberapa sifat kimia tanah PMK dengan aplikasi kompos sebagai bahan amelioran serta pengaruhnya terhadap pertumbuhan dan hasil tanaman caisim (Brassica juncea L.) sebagai tanaman indikator. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan yang terdiri dari tanpa kompos (K0), kompos 5 ton/ha (K5), kompos 10 ton/ha (K10), kompos 15 ton/ha (K15) dan kompos 20 ton/ha (K20). Hasil penelitian menunjukkan bahwa aplikasi kompos dengan dosis 20 ton/ha (K20) mampu memperbaiki pH, C-Organik, KTK, P-tersedia dan Cadd, Mgdd, Kdd dan Nadd tanah PMK serta meningkatkan produksi tanaman caisim.
