This study aimed to observe the growth and yield of Chiherang rice (Oryza sativa L) and weeds in response of different planting methods and weeding frequencies. We conducted the study in Semampir, Argorejo, Sedayu Sub-district, Bantul District on April until August, 2018. We arranged field study using randomized complete block design in 3x2 factorials with 3 times repetition. First factor was Jajar legowo (J) stratified as 3 levels; 2:1 (J1), 4:1 (J2), dan 6:1 (J3). Second factor was weeding frequency in 2 levels which were 2 times in 14 and 70 hst (P1) and 3 times in 14, 49 and 70 hst (P2). Observed variables include Ciherang rice growth (plant height, total tillers, percentage of productive tillers, fresh and dried weight of each plant), components of rice yield (grain dry weight of each harvest, percentage of filled grains, yield of each hectares), and weeds (type of weeds, fresh and dry weight of weeds). We analyzed results using variance analysis with significant level of 5%, followed with 5% DMRT test. We found that application of jajar legowo planting method and weeding frequency do not correlates with all growth and weeding frequency variables of Ciherang rice and weeds. 2:1, 4:1 and 6:1 jajar legowo planting methods do not show significant impact both on Ciherang rice growth and yield, and also weeds. Both 2 times (14 and 70 hst) and 3 times (14, 49 and 70 hst) also do not have significant impact on all variables observed.Keywords: Jajar Legowo, Weeding Frequency, Ciherang Rice

Field experiments were conducted at Punjab Agricultural University, Ludhiana (Punjab) to study the effect of different agronomic aspects of bed planting on growth and yield of rice during Kharif seasons of 2012 and 2013. The 30 days old seedlings of both rice varieties PR-118 (V1) and PR-116 (V2) were transplanted on 15th June (D1), 30th June (D2) and 15th July (D3). The two rice varieties were transplanted under bed planting (M1) and conventional planting (M2) methods respectively. The results showed that growth parameters like number of tillers per plant, dry weight per plant leaf area index (LAI) and plant height were significantly higher in bed planting than conventional method. In bed planting method, grain yield of rice (48.82q/h) was found to be more than the conventional method (35.74 q/h) during 2012.Varieties PR-118 yielded 47.61q/h more than PR-116 (39.97 q/h) in bed planting. Yield contributing characters like number of effective tillers, number of grains per plant and 1000-grain weight of rice were more in bed planting than conventional method. Harvest index and biological yield was also found to be more in bed planting method than conventional planting. Rice transplanted on 15th June yielded (50.15q/h) more than 30th June (41.45q/h) and 15th July (35.27q/h). Similar results were found in Kharif 2013. Interaction between dates of transplanting and varieties and between varieties and planting methods were found significant.

The experiment was conducted to find out the effect of plant spacing on the performance of rice variety IR-64 and IR64-Sub1 under conventional and Submerged condition at the National Rice Research Institute (NRRI), Cuttack, Odisha during the Rabi season of 2018. Different planting densities were maintained using different spacing's. These include (S1) 15 cm × 10 cm, (S2) 15 cm × 20 cm. The experiment was laid out in a randomized complete block design with 3 replications spacing of 15 cm × 10 cm with produced the highest grain yield of 350 gm-2 in submerged condition on IR64-Sub1 rice cultivar, which was significantly higher than the yield with recommended density (15 cm × 10 cm with IR64 Sub1). This yield was increased due to higher number of panicles m-2. This result suggests that higher planting density (15 cm×10 cm) rather than increased number of seedling hill-1 is necessary for getting higher yield of IR-64Sub1 rice cultivar in continuous submerged condition (where V1=IR 64, V2=IR-64 Sub1, S1=15 cm×10 cm, S2=20 cm×15 cm).

ABSTRACT<br />    <br />As one of the silica (Si) accumulator, rice (Oryza sativa L.) requires large amounts of silica for growth. This study aimed to determine the effect of liquid silica fertilizer application on lowland rice growth and yield, and its roles in drought stress responses. The experiments were conducted at Sawah Baru rice field and Cikabayan Greenhouse Experiment Station, IPB, Bogor during the period of January to May 2016. The field experiment was set up in a randomized complete block design with 7 treatments and three replications. The greenhouses experiment was arranged in a split-plot randomized block design with 3 replications. The main plots were 5 levels of liquid silica fertilizer application, while the subplot was 5 level of various soil water contents. The results of the field experiment showed that the application of liquid silica fertilizer increased rice shoot dry weight, total and productive tiller numbers, and yield per plant, but did not increase yield per hectare. Meanwhile at greenhouse experiment, it showed that the use of liquid silica fertilizer reduced the number of rice stomata, but did not increase cuticle thickness and grain yield per plant. Silica application was not effective to alter drought in rice.<br /><br />Keywords: IPB 3S, silica fertilizer, soil water content, water use efficiency   <br /><br />

Rice is the main staple food in Indonesia. The high needs of national rice must be balanced with the high production of rice crops. One of the efforts to increase the production of rice is the application of liquid smoke originated from agricultural waste, namely husk. The research was aimed to determine the effect of the application of husk liquid smoke on rice growth and production. The research used a single-factor randomized block design (RBD) with 5 treatments and 5 replications. The treatments consisted of several concentrations of liquid smoke : 0% (control), 0.5%, 1%, 2%, and 3%. This research employed several stages; land processing, seedling nursery, rice planting, applicating the liquid smoke, fertilizing, maintaining plants, and harvesting. The results showed that the application of husk liquid smoke significantly affected all observational parameters. On the parameters of rice growth and production, the application of 2% liquid smoke showed the best result. The plant height increased by 25.80% and the number of tillers increased by 49.70% compared to the control. The highest increase is in the number of grains per panicle and the weight of 1000 grains was 4,984% and 26.78% respectively.

Entisol is a marginal soil spreading over some areas in Indonesia. It has loose soil consistency, low aggregation rates, sensitive to erosion, and low nutrient content. Entisol has high K deficiency.  Potassium plays an important role in rice growth (Oryza sativa). The aim of the research was to study the effects of  type and dose of potassium fertilizers on available K in Entisol and its uptake by rice plants. The study was arranged in a Randomized Complete Block Design with 2 factors, i.e. the types of potassium fertilizers (KCl, ZK and KNO3) and doses of potassium fertilizers (0 kg K2O ha-1, 50 kg K2O ha-1, 100 kg K2O ha-1, and 150 kg K2O ha-1), with three replications. The results showed that the type of potassium fertilizers applied resulted in similar effects on almost all soil and plant parameters. The dose of potassium fertilizers significantly affected all  soil and plant parameters, the higher the doses, the higher the values of the parameters observed.

Background: Curcuma aromatica Salisb is an important medicinal herb in Vietnam. It is exploited naturally, so its production is limited and in danger of extinction. Studying an organic farming model is a necessary orientation to exploit, conserve and provide quality raw materials. Methods: The present study was conducted to investigate the effect of surface coating types (A1: without coating, A2: straw coating and A3: polymer coating) and organic fertilizer amount (B1: 0; B1: 15, B2: 20, B3: 25 and B4: 30 ton ha-1) on growth and yield of Curcuma aromatica Salisb. The experiment was designed in a factorial randomized complete block design (RCBD) with three replications. The traits studied were: survival plant’s rate (%), leaf area (cm2), plant height (cm), number of leaves, fresh weight (g/plant), dry weight (g/plant), phenolic content/area (mg/20 m2), curcumol content/area (mg/20 m2). Result: The results of the experiment revealed that surface coating types and organic fertilization and their interaction were significant in growth and yield of Curcuma aromatica Salisb.

Marginal land along the coast should be utilized to increase the national rice production. In addition, the use of saline resistant varieties, it is necessary to determine the best seedling age for saline soil. This study aimed to evaluate the growth and yield responses of two rice varieties transplanted at different seedling age on saline soil. The experiment was arranged in a factorial Randomized Completely Block Design (RCBD) with three replications, conducted at saline coastal area of Baros, Yogyakarta, starting from January to June 2017. The first factor was rice varieties, consisting of Dendang and IR-64. Meanwhile, the second factor was the seedling age, consisting of 2 and 4 weeks after sowing (WAS) seedlings. The results showed that the growth and yield of two rice varieties (Dendang and IR-64) showed significant difference, and Dendang showed a better performance than IR-64. The higher yield of Dendang compared to IR-64 was supported by higher plant growth (shoot dry weight) and yield components (number of seeds per panicle, seed weight per plot, and productivity). The 2 and 4 WAS seedlings did not give significantly different effects on nearly all growth variables. However, 2 WAS Dendang rice seedlings had higher shoot dry weight. Meanwhile, IR-64 had higher leaf greenness in 4 WAS seedlings compared to that in 2 WAS seedlings.

Shallots is one of the important commodities in Indonesia. Demand for these commodities always increases along with population growth. To fulfill this demand, the production of shallots must always be increased. One way to increase the production of shallots is by fertilizing. This study aims to determine the dosage of NPK fertilizer which gives the best results for the growth and yield of shallots. The study was carried out in Sentani District, Papua Province, from November 2016 until March 2017.The study used the Randomized Complete Block Design (RCBD) with three treatments NPK Phonska fertilization (NPK 15-15-15 composition) and four repplication. NPK fertilizer used were: 1) NPK 300 kg/ha, 2) 250 kg/ha, and 3) 200 kg/ha. The meterials used were shaloot bulbs Keta Monca cultivar. The plot size was 1 x 5 m, with a spacing of 15 x 15 cm. NPK fertilizer was given at the age of 14 and 30 days after planting respectively with the dose of ½. The variables observed were plant height, leaf number, bulbs number per sample, diameter of bulbs, dry weight bulb per hectare The results showed that the treatment of NPK fertilizer dosage did not give a significant effect on almost all observation variables except on the dry weight of eskip bulb, where the treatment dose of 200 kg/ha NPK fertilizer gave the highest yield compared to other treatments. When observed from the growth components and production components, the dose of NPK fertilizer 200 kg/ha is the most consistent to provide better growth and yield.
