Abstract

The study was addressed to investigating the effect of cow manure application rate on organic rice growth and yield in the first cropping season. The study was conducted from January to April 2012 in Blora, Central Java, Indonesia. The experiment was arranged in Randomized Complete Block Design, consisting of four treatments and four replications. There were two types of control treatments i.e. organic fertilizer treatments (statistically analyzed) and conventional fertilizer (not statistically analyzed). The treatments were corn biomass, corn biomass+cow manure (7.5 tons ha-1), corn biomass+cow manure (10 tons ha-1) and cow manure (10 tons ha-1) with square spacing of 20 cm x 20 cm. The organic control treatments were corn biomass+sheep manure (7.5 tons ha-1) with spacing of 20 cm x 20 cm and corn biomass+cow manure (7.5 tons ha-1) with double-row spacing of 40 cm x 25 cm x 15 cm. For every treatment, the rate of corn biomass was 3 tons ha-1. All organic treatments were also added with 3 tons rice hull ash ha-1. The application of cow manure (10 tons ha-1) with square spacing or corn biomass+cow manure (7.5 tons ha-1) with double-row spacing resulted in better performance than those of other treatments.Keywords: corn biomass, grumosol, organic farming, rice hull ash, sheep manure

Abstract

Saturated soil culture (SSC) technology appropriate to prevent pyrite oxidation on tidal swamps and has been proved to increase the productivity of soybean on non-tidal swamp. The objective of the research was to determine the growth response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip, Tanjung Lago, Banyuasin District, and South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main-plot of the experiment was water depth in the furrow consisted of 10, 20, 30, and 40 cm under soil surface (USS). The subplot of the experiments was soybean varieties consisted of Tanggamus, Slamet, Wilis, and Anjasmoro. No-watering was arranged out of the design as a comparison. The result showed that nutrient absorption of N, K and Mn by Tanggamus was higher than those of other varieties, except K, however K absorption of Tanggamus was not significantly different from Anjasmoro. P and Fe absorption of Tangamus tended to be higher than the other varieties, although statistically they were not affected by variety. However, technically and economically, 20 cm USS was the most appropriate water depth for soybean production at tidal swamps.

Abstract

Oksidasi pirit di lahan sulfat masam menyebabkan pH tanah turun sehingga meningkatkan kelarutan aluminium dan besi. Budidaya jenuh air mempertahankan kedalaman muka air tanah dan membuat lapisan di bawahnya jenuh. Penelitian bertujuan menentukan pengaruh kedalaman muka air tanah dan ameliorasi terhadap beberapa sifat kimia tanah dan produktivitas kedelai. Penelitian dilaksanakan di lahan sulfat masam Desa Banyu Urip Kecamatan Tanjung Lago Kabupaten Banyuasin, Propinsi Sumatera Selatan, sejak Juni sampai Oktober 2012. Penelitian menggunakan rancangan petak-petak terpisahdengan 3 ulangan. Faktor utama adalah tinggi air dalam parit 10 cm dan 20 cm di bawah permukaan tanah dengan pembanding budidaya kering. Faktor kedua adalah amelioran : tanpa amelioran, kapur dan abu jerami. Faktor ketiga adalah genotipe Anjasmoro, Yellow Biloxi, Tanggamus dan Lawit. Hasil penelitian menunjukkan interaksi kedalaman muka air dan ameliorasi meningkatkan pH tanah menjadi 4,67; mempertahankan kadar P tanah 10,70 ppm; meningkatkan kadar K, Ca dan Mg tanah menjadi 1,15; 11,70 dan 6,90 me/100 g. Kadar Fe tanah turun menjadi 12,14 ppm sedangkan kadar Al dan kejenuhan Alturun menjadi 2,06 ppm dan 10,36 persen. Tanggamus memiliki produktivitas tertinggi (2,47 t/ha) karena memiliki lebih banyak jumlah daun (31,5), jumlah cabang (4,5 - 5,3), jumlah buku produktif (27,67) dan jumlah polong isi (80,9).Pyrite oxidation causes the soil pH drops, thus increasing the solubility of aluminium and iron. Saturated soil culture maintains the water depth and makes the soil below saturated. This study aims to determine the effects of soil water depth and amelioration on soil chemical properties and soybean productivity. The experiment is conducted on acid sulphate soil Banyu Urip, South Sumatera Province, from June until October 2012. The experiment is arranged in a split split plot design with three replications. The main factor is water depth in the furrow consisted of 10 and 20 cm under soil surface. The second factor is ameliorant: without ameliorant, lime and straw ash. The third factors are genotypes: Anjasmoro, Yellow Biloxi, Tanggamus and Lawit. The results show that interaction of water depth and amelioration increase soil pH to 4.67, maintain soil P at 10.70 ppm and increase soil K, Ca and Mg to 1.15, 11.70 and 6.90 me/100 g. The soil Fe decrease to 12.14 ppm, whereas Al and Al saturated decrease to 2.06 ppm and 10.36 percent, respectively. Tanggamus has the highest productivity (2.47 t/ha), supported by higher number of leaves (31.5), branches (4.5 - 5.3), productive nodes (27.67) and filled pods (80.9.)

Abstract

Indonesia is facing soybean shortage and the low productivity of soybean production from decreasing acreage. Saturated soil culture (SSC) could be one of the solutions for marginal land with drainage problem. Saturated soil culture is cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. Farmers can use on-farm inputs that are normally available at the production site. An organic farming system may be able to ensure local and regional food security through continuous production. The study was conducted at Cikarawang Experimental Station of Bogor Agricultural University, Indonesia, from December 2009 to February 2011. The objective of the research was to determine the influence of organic fertilizer application on the productivity of two varieties of soybean, “Anjasmoro” and “Wilis”,    in organic saturated soil culture conducted in two cropping seasons. Prior to the experiment all plots were applied with 2 ton.ha-1 of dolomite, 2 ton.ha-1 of rice hull ash, and 10 ton.ha-1 of chicken manure. The experiment of the first season used split plot design with six replications. The main-plot was organic fertilizer that consisted of chicken manure only (20 ton.ha-1), chicken manure (10 t.ha-1) + Centrosema pubescens (4.2 t.ha-1), chicken manure (10 ton.ha-1) + Tithonia diversifolia (4.2 t.ha-1). The sub-plot was soybean varieties “Anjasmoro” and “Wilis”. The soybean productivity was not affected by the application of organic fertilizers. “Willis” productivity (1.98 t.ha-1) was higher than “Anjasmoro” (1.80 t.ha-1). The experiment of second season used split-split plot design with three replications. The main-plot consisted of 50 and 100% fertilizer rate of the first cropping season; the sub-plot was the same types of organic fertilizer with soybean varieties as sub-sub-plot. Rate of fertilizer, types of organic fertilizer and soybean variety did not affect productivity. Application of 50 and 100% rate of fertilizer in the second season produced 2.41 and 2.55 t.ha-1 of dry seeds, respectively. Soybean plants treated with chicken manure, green manure from C. pubescens and T. diversifolia produced 2.45, 2.50 and 2.49 t.ha-1 of dry seeds, respectively. “Anjasmoro” and “Wilis” produced 2.50 and 2.45 t.ha-1 of dry seeds, respectively. Productivity in the second season was 26.26-36.61% higher than those of the first cropping season.

Abstract

The application of organic fertilizer, especially manures, for crop production has long-term effects for soil nutrients availability and improvement of soil structure. The improvement of soil properties involves interactions of various types of microorganism in the soil. The research aimed to study the effects of different types of manures on the diversity of functional soil microbes and its effects on organic green mustard production. The experiment was conducted at IPB organic research field, Cikarawang, Darmaga, Bogor, from April to June 2015. The experiment used a randomized complete block design with two factors; the first factor was types of manure, i.e. chicken, cow, and goat manures; the second factor was manure rates, i.e. 0 and 10 ton.ha-1, so there were six treatments in total, replicated three times. The results showed that chicken manure application resulted in a higher mustard green yield and soil-P content than application of goat manure. The addition 10 ton.ha-1 of manures increased C-organic, N, K, and C/N ratio in soil significantly, but mustard green production was not affected. The diversity of microbe population of the soil treated with all types of manures was high. The addition 10 ton.ha-1 of manures decreased the total number of microbes, but increased the number of cellulose-degrading microbes. The population of cellulose-degrading and phosphate-solubilizing microbes in the soil applied with cow manure was higher than those applied with the other manures.

Abstract

Cowpea (Vigna unguiculata L. Walp) is one of the potential substitutes of soybean due to its similar nutritional content. This study aims to determine the optimum rate of N fertilizer for the production of cowpea, and to determine the effects of the interaction between N fertilizer rates and goat manure application on cowpea production. The experiment was organized in a split-plot with a complete randomized block design with three replications. The main plot was goat manure, i.e. 0 and 5 tons.ha-1; the sub-plot was nitrogen fertilizer with five rates (0, 50, 100, 150, and 200% of the recommended rate), i.e. 0, 22.5, 45, 67.5, and 90 kg N.ha-1. Application of N fertilizer reduced the 100-seed weight and slightly reduced cowpea yield and yield components. Application of goat manure increased seed dry weight per plant, number of pods per plant, dry pod weight per plant, seed dry weight per m2, productivity, 100-seed weight, and the harvest index. There was no significant interaction between goat manure and different rates of nitrogen in affecting cowpea growth.

Abstract

Pruning is one of the techniques to improve plant growth and production. The aim of this research was to determine the effect of pruning on vegetative and generative growth, and fruit quality of ‘Crystal’ guava. The experiment was conducted from September 2016 to April 2017 at Cikabayan Research Station of Bogor Agricultural University, Dramaga, Bogor, Indonesia (-6.550780, 106.714531). The experiment used completely randomized design with six replications. There were three treatments i.e. a) pruning by leaving 4 pairs of leaves, b) pruning by leaving 8 pairs of leaves, and c) control (without pruning). Pruning was applied after shoot leaves grew fully. The result showed that pruning significantly increased the total number of shoots and generative shoots. Pruned plants produced more flower and fruit than un-pruned ones. Pruning by leaving 4 pairs of leaves tended to produce higher number of flower and fruit than those by leaving 8 pairs of leaves. Fruit weight and internal fruit quality were not affected by pruning.

Abstract

The study was conducted to investigate the effectiveness of Arbuscular Mycorrhizae Fungi (AMF) to make a symbiosis with physic nuts under drought stress condition. The experiment was carried out in plastic house in Kota Palu, Central Sulawesi, from October 2008 to January 2009. The experiment used completely randomized block design with 3 factors and 3 replications. The first factor was AMF type i.e. without AMF, AMF Glomus sp-1p, AMF Acaulospora sp-1p, and mixture of Glomus sp-1p and Acaulospora sp-1p. The second factor was the provenances of physic nut i.e. Palu, NTB, IP-1A, and IP-1P. The third factor was soil water content i.e. 80 and 40% of field capacity. The results showed that the application of AMF resulted in better growth of all provenances especially ecotype IP-1P, which was sensitive to drought, compared to control (without AMF). At 40% field capacity, mixture of Glomus sp-1p and Acaulospora sp-1p. was more effective compared to single AMF in improving plant growth. The highest AMF infection was found in ecotype Palu inoculated with mixture of Glomus sp-1p and Acaulospora sp-1p. Key words: infection level, Glomus, Acaulospora

Abstract

Five shallot varieties namely ‘Bauji’, ‘Bantaeng’, ‘Tuk Tuk’, ‘Rubaru’, and ‘Palasa’ were examined for their leaf pigment, total phenolic content, leaf tissue nutrient analysis, and green shallot production. The experiment was conducted in in Cikabayan greenhouse, IPB University, Dermaga, Bogor, arranged in a randomized complete block design with single factor (variety) and three replications. The observations were carried out three times in the maximum vegetative period, consisting of 20, 30, and 40 days after planting. The result showed that ‘Palasa’ had the highest leaf pigment content, such as chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid, while the anthocyanin content fluctuated between the varieties and observation times. ‘Palasa’ also had the highest sulfur content in the leaf tissues. On the contrary, ‘Palasa’ had the lowest production compared to other the varieties. Meanwhile, ‘Bantaeng’ had the highest green shallot production, total nitrogen, and total phosphorus content in the leaf tissues. Total phenolic content fluctuated in the five varieties and observation times. The highest total phenolic content was in ‘Tuk Tuk’, observed 20 days after planting. The principal component analysis (PCA) showed that the five shallot varieties formed three clusters. The first was ‘Palasa’, the second cluster was ‘Bauji’, ‘Tuk Tuk’, and ‘Rubaru’, while the third cluster was ‘Bantaeng’. ‘Palasa’ had the highest content of leaf pigment, while Bantaeng had the highest leaf production. Leaf pigment and total phenolic content changed along with the increasing plant age in all varieties.

Abstract

A well-structured root system is essential to ensure optimal plant growth and yield. Two experiments were conducted to determine the effects of plant growth promoting rhizobacteria (PGPR) on the root system of okra plant. These experiments were arranged with a completely randomized design. The first experiment was conducted in the growth chamber with 8 different bacterial isolates consisting of Methylobacterium sp., Bacillus sp., Bacillus methylotrophicus, Flavobacterium tirrenicum, Providencia stuartii, Azotobacter vinelandii, Methylocystis parvus and PGPR consortium. The second experiment was conducted in the greenhouse and examined the effects of four poultry manure rates, i.e. 0, 6, 12 and 18 ton ha-1, or equivalent to 0, 75, 150 and 225% of recommended rates and how these are altered with the presence or absence of PGPR. The results of the experiments showed that, PGPR significantly improved root architecture; the number and length of lateral roots was increased by 242.86% and 777.79% respectively, as well as the dry weight of the roots and shoots of okra plant by 236.36% and 333.33%, respectively. Moreover applying 150% (12 t.ha-1) of the recommended rate of poultry manure enriched with PGPR was found to be most effective in terms of improving the growth and root attributes of okra plants.
