The use of Bacillus bacteria as biofertilizers (BF) increases since the detrimental effects of inorganic fertilizers on the agricultural environment spread out. The objective of this research was to study the influence of bio fertilizer and in combination with inorganic fertilizer on the productivity of rice fields. The experiment was a two-factor treatment arranged in a split-plot design with three replications using a randomized complete block design (RCBD). The first factor was fertilizers, which were used as the main plot. The second factor was paddy varieties as a subplot. The results showed that the combination of inorganic and bio fertilizer application of (150 kg NPK ha-1 + 75 kg Urea ha-1 + 4 L BF ha-1) and (300 kg NPK ha-1 + 150 kg Urea ha-1 + 4 L BF ha-1), improved soil available phosphorous (P) of 12.04%, 40.69%, and 44.05%, respectively compared to control treatment, the inorganic fertilizer application (300 kg NPK ha-1 + 150 kg Urea ha-1), and the bio fertilizer application (4 L BF ha-1). In addition, the application of (300 kg NPK ha-1 + 150 kg Urea ha-1 + 4 L BF ha-1) increased productive tillers per plant as 28.13% and 16.48% compared to the control and the inorganic application, respectively. Moreover, by using Mekongga variety, applying the inorganic and bio fertilizer at rates of (300 kg NPK ha-1 + 150 kg Urea ha-1 + 4 L BF ha-1) increased rice yield of 64.08% and 30.33% compared to the control and the inorganic fertilizer application; while, by using IPB 3S variety, the rice yield increased by 85.80% and 10.34%, respectively. These findings are significant as they demonstrate the potential of biofertilizers to enhance soil fertility and rice productivity, thereby advancing sustainable farming practices.

ABSTRACT Perennial sow-thistle (Sonchus arvensis L.) has been traditionally used as a medicinal plant. It contains secondary metabolites with several functions mainly as antioxidant, and its ability to dissolve kidney stones. It is expected that proper harvest time could increase leaf production and secondary metabolites, especially flavonoids. This study aimed at determining harvest time and flavonoid production of Perennial Sow-thistle. The research was conducted in July 2015 to December 2015 at IPB Organic Farm Cikarawang, Dramaga, Bogor. This study used randomized block design with single factor namely harvest time and 3 replications. There were 4 harvest time treatments i.e. (1) leaves harvested gradually i.e. basal leaves at vegetative then upper leaves harvested at early generative stage, (2) leaves harvested gradually i.e. basal leaves at vegetative then upper leaves harvested at maximum generative stage, (3) basal leaves harvested together with upper leaves at early generative stage, and (4) basal leaves harvested together with upper leaves at maximum generative stage. The result showed that basal leaves were harvested at vegetative stage then stem leaves harvested at maximum generative stage produced the highest fresh weight of upper leaves. Total flavonoids content were found the highest in upper leaf when basal leaves harvested together with the upper leaves at budding and flowering. Keywords: leaf area, luteolin, nutrient content, organic ABSTRAKTempuyung (Sonchus arvensis L.) secara tradisional telah digunakan sebagai tumbuhan obat.

ABSTRACT Kristal guava is one of the popular guava cultivars nowadays. The guava has white flesh and not-perfectly-round shaped that resembles a crystal and seedless. However, during the growth period fruit undergoes several physical and chemical changes and susceptible to insect infestation and other damage, all of which can reduce their commercial value and thus cause significant yield and economic losses. The aim of this research was to evaluate the influence of different color and bagging materials on guava fruit development and quality. The research was conducted at farmer farm located in Cikarawang Dramaga, from November 2013 to April 2014. This research was arranged in a randomized block design with one factor, consisted of ten treatments and five replications. The treatments were red plastic, yellow plastic, green plastic, blue plastic, sponnet with red plastic, sponnet with yellow plastic, sponnet with green plastic, sponnet with blue plastic, sponnet with transparent plastic and unbagged. Fruit quality assesment was conducted in Postharvest Laboratory of Agronomy and Horticulture Department, Bogor Agricultural University and Center for Tropical Horticultural Studies. The result showed that bagging improved fruit size, external quality and accelerated fruit maturity. Sponnet with red plastic bagging resulted in the biggest fruit at harvest. Sponnet with yellow or with red plastic baggings were able to maintain fruit peel smoothness up to 85%. Sponnet and plastic bagging resulted in better external quality than bagging with plastic only. Bagging did not show any effect on internal fruit quality. Keywords: colored bag, guava cv.

ABSTRACT Cat whisker has been known as multifunctional herb. Good agricultural practice of cat whisker is necessary to produce high yield and good quality of simplicia as source of bioactive compound. As ratoon-harvested plant, fertilization and harvest management are important to maintain growth condition and production at each harvest. The objective of this study was to determine the best technique of fertilizer application and cutting height to obtain the highest simplicia of cat whisker production. The experiment was arranged in split plot design with three replications. The treatment were technique of organic fertilizer application (one time/10 ton ha-1 at transplanting time, and split /5 ton ha-1 at transplanting time+5 ton ha-1 at second harvest) as main plot and cutting height (one time /10, 20 and 30 cm above ground level) as sub plot. Growth and production data were collected. Result showed that the application of 10 ton ha-1 manure at transplanting time and harvest at 30 cm cutting height produced the highest simplicia production. One time application of fertilizer produced 3.09 ton ha-1 meanwhile split application only produced 2.81 ton ha-1 of simplicia. Harvest at 30 cm cutting height resulted in higher total simplicia production (3.24 ton ha-1) than at 10 dan 20 cm cutting height (2.66 and 2.95 ton ha-1, respectively. The average total simplicia production in 6 times harvesting during 23 weeks after transplanting was 2.95 ton ha-1. There is no significant interaction effect of the treatments on total simplicia production.

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.

Sonchus arvensis L., commonly known as perennial sow thistle, field milk thistle, among other names, is a weedy species that has medicinal values. Belongs to the Daisy family (Asteraceae), S. arvensis has a rosette form and it can be harvested more than once. The determination of harvest interval for ratoon of S. arvensis is necessary because ratooning can save time to produce the consecutive plant biomass, but the second harvest must be conducted at the correct time as it will determine the quantity and quality of leaves. As source of herbal medicine, cultivation of S. arvensis with organic fertilizer is preferred, and determination of organic fertilizer rates is also important for ratooning. The purpose of the study was to evaluate the plant growth response and yield with different chicken manure rates and different harvest intervals. The field experiment was conducted at IPB experimental station in Cikarawang, Darmaga Bogor, Indonesia. The study used a randomized complete block design with different manure rates (0, 7, 14, 21 ton.ha-1) and various harvest intervals (6, 8, and 10 weeks after the first harvest) as treatments. The results showed that for the first harvest, the effect of chicken manure rates was linear almost on all variables. For the ratoon (second harvest), manure rate of 14 ton.ha-1 (for first harvest) added with 4 ton.ha-1 (after first harvest) was enough for leaf production. The results indicate that ratoon should be harvested at 10 weeks after the first harvest to obtain the highest yield. The interaction between manure rates and harvest interval was not significant for growth variables of the second harvest.
