Abstract

The study was conducted to determine the effect of extract of cacao fruit waste compost at various levels of P fertilizer application on monomeric Al in the soil and acidity characteristics of Palolo Oxic Dystrudepts. In addition, this study was aimed to determine the effect of extract of cacao fruit waste compost at various levels of P fertilizer application on P uptake, P fertilization efficiency and maize growth in the Oxic Dystrudepts. The experiment was carried out in two phases. Phase I wasa soil experiment without plant, while in phase II, the experiment was conducted in a greenhouse using maize as an indicator plant. The experimental design used wasatwo-factorial randomized complete design, where the first factor was rate of cacao fruit waste compost extract produced from 8-day fermentation process(D) consisting of D0 = 0ℓ.ha-1 (control), D1 = 500ℓ.ha-1, D2 = 1000ℓ.ha-1, and D3 = 2000ℓ.ha-1. The second factor was rate of SP-27 (P) fertilizer consisting of P0 = 0 kg.ha-1, P1 = 50 kg.ha-1, P2 = 100 kg.ha-1, and P3 = 200 kg.ha-1. Each treatment was replicated three times, hence, there were 4 x 4 x 3 = 48 experimental plots. The results showed that increasing rates of cacao fruit waste compost extract application at all rates of P fertilizer significantly decreased monomeric Alconcentration in the soil solution, and thismonomeric Al concentration also decreased with increasing rates of P fertilizer at all rates of cacao fruit waste compost extract application. The application of compost extract at2000ℓha-1 combined with P fertilizer at200 kgha-1represented the best combination since it decreased the concentration of monomeric Al in the soil solution from 650.8μM to 339.7μM. The results alsoshowed that application of cacao fruit waste compost extract with increasing rates significantly decreased soil exchangeable Al and  increased soil pH, P uptake efficiency of maize, soil available P, soil organic C level, soil CEC, plant dry weight, and P concentration and uptake of maize. In the experiment with maize as an indicator plant, P concentration and P uptake in maize tissue also increased with increasing in P fertilizerrate. Application of P fertilizer at the rate of 200 kg Pha-1 produced the highest P concentration (0.50%) and P uptake (238.61 mg P plant-1) in the plant at 38 days after planting (DAP). P uptake efficiency increased with increasing rates of cacao fruit waste compost extract, while the efficiency of P uptake decreased with increasing rates of P fertilizer application. Key Words : Cacao fruit waste, compost extract, monomericAl, Oxic Dystrudepts, and P fertilizer.

Abstract

The objective of this research was to study the effect of phosphorus (P) and calcium (Ca) fertilizers on productivity and nutrient uptake of two soybean genotypes under saturated soil culture.          The experimental design was a Split Split plot with three factors i.e. P fertilizer, Ca fertilizer and genotype planted under saturated soil culture. Saturated soil culture with P fertilizer (72 kg P­2O5 ha-1) and lime (1 ton ha-1) increased the number of pods and grain weight plot-1. Tanggamus variety had higher number of pods and grain weight per plot than Anjasmoro variety. Interaction of phosphorus fertilizer 72 kg P­2O5 ha-1 with lime 1 ton ha-1 increased grain weight plot-1. Largest direct effect on increasing grain weight is plant height and the number of branches. The application of P fertilizer (72 kg P­2O5 ha-1) and liming (1 ton ha-1) also gave highest uptake of P and Ca.  Saturated soil culture technology can be applied to increase soybean nutrient uptake and productivity. Key Words : Productivity, Soybean, saturated soil culture.

Abstract

Laju pembasahan dan tingkat pembasahan disamping bahan organik dipercaya mempengaruhi proses awal terjadinya koalesen agregat tanah yang dapat meningkatkan kekuatan tanah.  Penelitian ini dirancang untuk memisahkan kedua pengaruh itu sehingga dapat dilakukan perbaikan pengelolaan yang dapat dievaluasi dalam rangka meningkatkan efisiensinya yaitu apakah pengelolaan harus berfokus pada perbaikan teknik irigasi atau meningkatkan bahan organik, atau keduanya.  Polivinil alkohol (PVA) yang merupakan salah satu senyawa kimia yang dapat meningkatkan stabilitas agregat  diberikan secara terkontrol dengan menggunakan sprayer terhadap agregat tanah berdiameter 0,5-2 mm.  Sampel tanah bertekstur kasar dan halus ditempatkan dalam ring dan laju pembasahan air (1, 10 dan 100 mm/jam) menggunakan sistem tetesan yang dikontrol oleh pompa peristaltik.  Sampel tanah kemudian dibasahi hingga mendekati jenuh atau hisapan               10 kPa selama 24 jam, kemudian didrainase dengan menggunakan plat tekanan pada hisapan                100 kPa.  Pengukuran tahanan penetrometer diukur dengan menggunakan penetrometer kerucut berdiameter 2 mm, sedangkan kekuatan tarik diukur dengan alat uji tidak langsung Brazilian. Tahanan penetrometer lebih rendah pada sampel tanah yang mendapat perlakuan PVA sebelum pembasahan dan pada sampel tanah yang yang mendapat hisapan lebih tinggi (10 kPa) setelah pembasahan awal.  Pengaruh tersebut semakin menonjol pada tanah bertekstur kasar.  Pada kedua jenis tekstur tanah, kekuatan tarik meningkat dengan semakin tingginya laju pembasahan dan tingkat pembasahan (lebih besar pada kondisi hampir jenuh).  Laju pembasahan cenderung lebih penting dalam mendorong proses terjadinya koalesen agregat dari pada tingkat pembasahan
