Abstract

Introducing high yield varieties to farmers by demonstration plots is one of efforts to accelerate the adoption of these varieties. The objective of study was to determine the preferences of farmers on the characteristics of rice high yield varieties on medium freshwater swampland. The study was carried out on farmer's land at Hamayung village, Daha Utara subdistrict, Hulu Sungai Selatan regency in 2017. There were 20 selected farmers as samples by simple random sampling. Collected data were farmer characteristics and rice morphology that obtained by interviews with farmers using questionnaires and farmer observations on plant growth of 10 rice high yield varieties in the field before harvesting. The obtained data were tabulated, grouped and analyzed descriptively. The results showed that (1) the most preferred performance of plants was plant age, panicle length, plant type, grain shape and plant height and (2) Mekongga, Inpari 30, Inpara 6, Inpari 9, Inpari 17, Ciherang and Inpara 8 were the preferred variety (from the most preferred order) varieties based on their agromorphology.

Abstract

Root-induced Changes in the Rhizosphere of Extreme High Yield Tropical Rice: 1. Soil Chemical Properties     (E Purnomo,  M Turjaman, A Hairani, A Mursyid, D Choiron, R Yulia and M Osaki): Padi Panjang cultivar is one of many local rice cultivars found in South Kalimantan that yields 8 Mg ha-1 without fertilizer after last transplanting. The mechanisms involved in sustaining nutrient supply to sustain the extreme high yield are of interest. The following work aims to investigate the changes of soil chemical properties in rizhosphere of Padi Panjang cultivar. The Padi Panjang cultivar was grown in a rhizobox filled with soils from 3 different villages in Banjar Regency, South Kalimantan Province, namely, Kuin, Bunipah and Guntung Papuyu. The rice plant was grown for 5 weeks. At the end of the growing period, soil chemical properties such as pH, aluminum (Al), phosphorus (P), potassium (K+), ammonium (NH4+), and nitrate (NO3-) were measured. The results showed that Padi Panjang cultivar had the capability to change the soil chemical properties in the rhizophere. The impact was more extent compared with IR64 cultivar. The changes were depended on soil character, especially, soil texture. The soil from Guntung Papuyu was the least affected by root. It was observed that Padi Panjang cultivar acidified more than IR64. A depletion zone of K+ and NH4+ was found in the rhizosphere of both Padi Panjang and IR64 cultivars. The depletion zone of these ions could reach as far as 3 cm from the rhizosphere. For P, the depletion zone only occurred in the rhizosphere soil of IR64 cultivar. However, for Padi Panjang cultivar, the depletion zone of P did not exist. The Padi Panjang cultivar was able to maintain P concentration the same as or higher than control soil without plant. This is the first report showing that Padi Panjang cultivar can be considered as efficient lowland rice cultivar in absorbing not only P but also K in a P- and K-deficient-soil.

Abstract

Our previous studies showed that the extreme high yield tropical rice (Padi Panjang) produced 3-8 t ha-1 without fertilizers. We also found that the rice yield did not correlate with some soil properties. We thought that it may be due to ability of root in affecting soil properties in the root zone. Therefore, we studied the extent of rice root in affecting the chemical properties of soil solution surrounding the root zone. A homemade rhizobox (14x10x12 cm) was used in this experiment. The rhizobox was vertically segmented 2 cm interval using nylon cloth that could be penetrated neither root nor mycorrhiza, but, soil solution was freely passing the cloth. Three soils of different origins (Kuin, Bunipah and Guntung Papuyu) were used. The segment in the center was sown with 20 seeds of either Padi Panjang or IR64 rice varieties. After emerging, 10 seedlings were maintained for 5 weeks. At 4 weeks after sowing, some chemical properties of the soil solution were determined. These were ammonium (NH4+), nitrate (NO3-), phosphorus (P) and iron (Fe2+) concentrations and pH, electric conductivity (EC) and oxidation reduction potential (ORP). In general, the plant root changed solution chemical properties both in- and outside the soil rhizosphere. The patterns of changes were affected by the properties of soil origins. The release of exudates and change in ORP may have been responsible for the changes soil solution chemical properties.Keywords: Ammonium, electrical conductivity, iron, nitrate, oxidation reduction potential, pH, phosphorus [How to Cite: Purnomo E, D Choiron, R Yulia, H Halim, Krisdianto, A Hairani and M Osaki. 2012.

Abstract

Organic residues often exhibit different physico-chemical properties and affect the soil ecosystem in different ways. Hence, the study of their impact on soil is essential to benefit from their potential as amendments and to avoid adverse environmental effects. It is required to study the role of rice straw in the changes of soil properties during decomposition processes in the rice field. The research was conducted on potential acid sulphate soil (PASS) and actual acid sulphate soil (AASS) in the glass house. Soil pH, Fe2+, organic-Fe, total N and available P were observed at 2, 4, 6 and 8 weeks after planting (WAP). The result showed that rice straw application : (1) decreased soil pH of PASS and increase soil pH of AASS; (2) tended to increase Fe2+ both in PASS and AASS; (3) stimulated the organic-Fe concentration in AASS was higher than organic-Fe concentration in PASS; (4) had no different effect in total N and decreased P concentration in the both of soil during observation. P concentration on PASS was lower than on AASS.Keywords: Decomposition, rice straw, soil chemical properties, soil type[How to Cite: Hairani A and A Susilawati. 2013.Changes of Soil Chemical Properties during Rice Straw Decomposition in Different Types of Acid Sulphate Soils.

Abstract

Experiment was conducted on shallow peat with depth (50 - 75 cm) and C/D flooding type at Purwodadi village, Maliku District, Pulang Pisau Regency, Central Kalimantan in wet season 2003.  Ten samples were taken from areal of 2 ha for studying characteristics of shallow peat.  Nutrient absorption of crops and soil nutrient after harvesting  were also analyzed.  This experiment used split plot design with three replications.  As a main plot was input application (M1) : manure (5.000 kg/ha), lime (2.000 kg/ha), urea (150 kg/ha), SP36 (312.5 kg/ha) and KCl (200 kg/ha) for tomato and SP36 (187.5 kg/ha) and KCl (125 kg/ha) for red pepper and without application (M0). Five varities of red pepper (Tombak 1, Tanjung 1, Tanjung 2, Prabu and Hot Chilli) and, five varities of tomato (Oval, Ratna, Mirah, Berlian and Permata) were as subplots. The results showed that soil chemical characteristics were : peat depth 50 - 75 cm, phyrite depth 75 - 100 cm, soil pH 3.5 - 4.0, C-organic content 12 - 24 %; range of nutrient availability : N (0.4 - 0.6 %), P (30 - 50 ppm P), K (0.1 - 0.3 me/100 g), Ca (1 - 6 me/100 g), Mg (0 - 1 me/100 g), Fe (20 - 120 ppm Fe) and Al (1 - 7 me/100 g).  Availability of nutrients N, P, K, Ca, and Mg was low, and it could be increased by application of some inputs such as manure, lime, urea, SP36 and KCl.  Low nutrient availability and crop absorption especially K, Ca, and Mg was a main factor that retarded crop growth.  Red  pepper and tomato yields ranged 0.59 - 4.02 and 4.77 - 10.99 t/ha for control treatments and 3.44 - 7.72 and 14.85 - 35.98 t/ha with input application.   Key words : amelioration, yield potency, red pepper, tomato, shallow peat
