Inadequate disposal of poultry litter (PL) may promote eutrophication of water bodies due to its high nutrient content, including phosphorus (P). Thus, recycling P from PL to produce organomineral fertilizer (OMF), reduces the dependence on finite mineral P reserves, and also reduces P losses from soil. In this context, a field experiment was carried out to assess the agronomic effectiveness of a granular PL-derived OMF applied to maize and soybean in a highly weathered tropical soil. OMF was compared to single superphosphate (SSP) at five P rates between 0 and 70 kg ha−1. The shoot dry weight (SDW) and grain yields of soybean and maize were affected by P rates; however, no difference between OMF and SSP was found. A similar trend was observed for soil P and P uptake. The leaf P content and soil pH were not affected by either P sources or P rates. Although there was no difference between OMF and SSP on the crop yields, OMF had the highest relative agronomic effectiveness based on the SDW. These results show that the production of granular OMF from PL is a viable alternative to conventional P fertilizers and reduces the dependence of mineral P reserves.

Inceptisol is a young and newly developed soil so it needs to be optimized for crop cultivation. The aim of this research is to know the availability of soil P, P uptake and corn yield after application of granular composting of sago waste (KGES) together with phosphate fertilizer to Inceptisols soil. The experimental treatment was KGES which consisted of three levels: without KGES, 40 tons KGES ha-1, and 80 tons KGES ha-1, and the use of SP-36 (P) fertilizer consisting of three levels: without P fertilizer, 120 kg P ha-1, and 240 kg P ha-1. The experiment used a complete randomized design with 3 replications. The result of the experiment was analyzed variance and relationship test using interlaced analysis. The results showed that KGES together with phosphate fertilizers could increase soil pH causing phosphate to be available and plant roots could absorb nutrient phosphate well, so that the yield of corn kiln dry weight also increased. The highest yield of dry weight of grains (7.85 tons per ha) was obtained from a combination of 80 tons of KGES ha-1 and 240 kg P ha-1.Keyword: Keywords: Ella Sago, Inseptisols, maize, phosphate

Jabon (Anthocephallus cadamba Roxb.) is one of fast-growing species with high economical value, and well adapted on some of soil types. The aims of this research were to analyze the effectiveness of AMF species isolated from Samama (Anthocephallus macrophyllus (Roxb.) Havil) and to determine the favorable dose of nitrogen and phosphate fertilizer for Jabon growth. The research was conducted CRD-split plot design main plot was Acaulospora sp.1 (M1), Glomus sp.1 (M2), Acaulospora sp.2 (M3), Acaulospora sp.3 (M4), Glomus sp.2 (M5). While the fertilizer as the sub-plot, consist of control (P0), urea 0.5g+rockphosphat 2g (P1), urea 1g+rockphosphat 4g (P2). The result showed that AMF and fertilizer applications effectively improved Jabon grown, especially in height, stem diameter, and shoot dry weight. The interaction (M4P1) increased plant height 154.73%, diameter 75.38% and shoot dry weight 376.09% compared with control. P1 treatment was better for growth of Jabon that was inoculated by mycorrhiza. Acaulospora sp.1 (M1) originally from Samama without fertilizer had the best effectiveness for Jabon growth.Key words: Acaulospora, indigenous

This paper describes the use of an isotope injection technique for assessing the agronomic effectiveness of phosphate sources in undisturbed soils in field and glasshouse experiments. A special injection apparatus consisting of 20 syringe needles linked to a common reservoir was used to label soil cores 150 mm in diameter and 150 mm in height, without significantly disturbing the soil structure and established perennial ryegrass (Lolium perenne) root patterns. Variations in the amount of phosphorus (P) taken up by plants from single superphosphate (applied at 30, 60, and 100 kg P/ha), from 30% acidulated North Carolina phosphate rock (60 g P/ha), and from 'as received' North Carolina phosphate rock (60 kg P/ha) were indicated by the specific activity of the plant P. Percentages of plant P derived from the fertilisers were calculated on the basis of the specific activity of the fertilised treatments and the controls. The technique provides a simple method of comparing the agronomic effectiveness of phosphate sources in undisturbed soils and, unlike total dry matter yield and P uptake, is relatively unaffected by environmental factors.

Abstract Strategies to reduce the economic and environmental costs of phosphate (P) fertiliser use in mixed pastures through plant breeding are focussed on inefficiencies in the legume component. One approach is breeding within white clover for root systems with improved P acquisition properties. Selection for root length per unit root weight (specific root length, SRL) showed that higher SRL plants could retain more biomass in the above ground fraction with decreasing soil P, whereas plants with lower SRL diverted more biomass to roots. Back cross 1 (BC1) generation interspecific hybrids between white clover and a wild relative, Trifolium uniflorum L., may possess additional root traits influencing P acquisition. In glasshouse experiments, some T. repens × T. uniflorum hybrids, back-crossed to white clover, also exhibited higher shoot dry weight than their white clover cultivar parents at low nutrient supply levels and low to intermediate soil Olsen P. This, combined with low internal P concentrations, suggests some BC1 hybrids may be more tolerant of low soil P than white clover. Differences in both P acquisition ability and internal P use efficiency may contribute to the observed yield differences. There are good prospects for delivery of new-generation clover cultivars with improved phosphate use efficiency to New Zealand farmers.

Response of Salak Seedlings (Salacca Zallaca) Growth to Dosage of Endomycorrhizal Spore in Quartz Sand and Zeolite Carrier Media. This study aimed to study the effect of endomycorrhizal spore dosage and carrier media that were applied directly to the roots of salak plants. The research designed as factorisl by using Randomized Block Design with 2 treatment factors. The first factor was number of endomycorrhiza spores consists of 4 levels i.e 0, 75, 150, and 225 spores per 500 g carrier media per polybag, while the second factor was the type of carrier media consist of 2 levels i.e zeolite and quartz sand. The results showed that interaction between endomycorrhizal spore dosage with   carrier   media   did   not   significantly   influence   the   growth   of   salak   seedlings. Endomycorrhizal spores in doses of 75, 150 and 225 spores per polybag increased root infection and leaf P nutrient content compared to control, but seed height, leaf area, shoot dry weight, root dry weight and total dry weight of seedlings not significantly difference. The zeolite carrier media caused root infection by mycorrhizal was higher than quartz sand media, but the P nutrient uptake and seedling growth were not significantly different. Based on the results of this study it is necessary to make a longer observation of the effect of endomycorrhizal spore doses and carrier media on the growth of salak seedlings.

Liners of Rosa `MEIrutral' (=Red Sunblaze) were potted in 11.5-cm pots using Fison's Sunshine Mix no. 2 amended with 0%, 10%, 20%, or 30% composted poultry litter (PL) by volume. Plants were grown for 3 weeks before cutting back to 5 cm for final forcing (short-cycle) and were fertilized with 200 mg N/liter from 20N–8.9P–16.6K on a three feed and one leach schedule for the duration of the experiment. By flowering, plants growing in the 30% PL media were dead or stunted. However, there was little difference in total number of flowers, days to flower, and root and shoot dry weight between the other treatments. Media pH rose from 6.6 to 7.4 and EC rose from 0.7 to 6 millimhos with increasing PL content. This result alone could explain the poor growth in the highest PL rate treatment. However, tissue N levels were supraoptimal for the 20% and 30% PL rates, and tissue P levels were excessive for all PL rates. If a high-quality source of composted PL is available, it could be used as a media component for potted rose production at rates <20%, but monitoring of pH and EC and modifying fertilization techniques may be necessary to ensure success.

Keterbatasan lahan potensial menyebabkan perluasan areal pertanian mengarah pada lahan gambut. Kendala pengembangan lahan gambut adalah rendahnya kandungan hara tersedia bagi tanaman. Fosfat (P) merupakan salah satu unsur hara makro yang penting untuk pertumbuhan dan produksi tanaman, disisi lain ketersediaan hara ini pada lahan gambut terbatas karena ikatan asam organik dan sifat yang mudah tercuci. Penelitian untuk menguji pengaruh ameliorasi dan inokulasi mikroba pelarut fosfat terhadap ketersediaan hara P di lahan gambut dilakukan di kebun pembibitan kelapa sawit petani di Riau dari Oktober 2013 - Maret 2014, menggunakan Rancangan Acak Kelompok pola Faktorial dengan 30 kombinasi perlakuan dan 3 kali ulangan. Variabel yang diamati meliputi : tinggi tanaman, lingkar batang, jumlah daun, lebar daun, panjang daun, kandungan hara tanaman, dan bobot biomasa bibit setelah 5 bulan di pembibitan. Hasil penelitian menunjukkan bahwa ameliorasi menggunakan kompos tandan kosong kelapa sawit mampu meningkatkan P tersedia, serapan P oleh batang dan akar, berat brangkasan dan berat kering batang. Sedangkan mikroba pelarut fosfat berpengaruh secara tidak nyata.The limitation of potential land leads agricultural development expansion to the peat soil area. Constrain of the peatland development is the low nutrient content that is required by plant. Phosphate is one of major growth and production limiting nutrient because of the solublelize of the organic acids and immobility The research was conducted from October 2013 – March 2014 at the farmer main nursery in Riau province to test the effect of amelioration and phosphate solubilizing microbe inoculation on P availability on palm oil seedling growth and production at peatland, used Randomized Block Design with 30 treatments and 3 replications. The parameters observed were plant height, leaf number, leaf width, leaf length, stem diameters, nutrient contents, also fresh and dry weight after 5 months at the main nursery. The result showed that palm oil empty fruit bunch compost as ameliorant increased P nutrient avaibility, P uptake, fresh and dry weight, whereas phosphate solubilizing microbe was unsignificant.

Improvement to animal genetics requires the supply of superior quality forage, such as alfalfa (Medicago sativa L.). Under tropical and subtropical conditions in Brazil, alfalfa cultivation has been restricted to the 'Crioula' cultivar, although studies have indicated that other cultivars have excellent potential of yield. The objective of this work was to evaluate the adaptation and longevity of 92 alfalfa cultivars to the tropical edaphoclimatic conditions by assessing shoot dry weight yield (SDWY), crude protein content (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and nutrient content in SDWY. The 'Crioula', 'P 105', 'Rio Grande', and 'Springfield' cultivars were the most promising owing to their higher yield and lower reduction in SDWY. Crude protein (CP) content varied among cultivars, with the highest value found in 'Pro INTA Lujan' (24.5%) and the lowest found in 'Pecos' (18.8%). NDF content ranged from 25.8% ('Key II') to 38.7% ('California 50'), while ADF content ranged from 16.4% ('F 708') to 24.8% ('Diamond'). Nutrient levels of all cultivars were within the levels considered appropriate for tropical conditions.
