<p>Hybrid rice has genetic traits such as sturdy stems, long and bushy dwarfs, short lifespan of 110-145 days, has large number of tillers, and leaves are dark green. Productivity of hybrid rice reached 6-12 tons-1ha. To obtain maximum production, hybrid rice varieties should be planted on fertile land, nutrients must be available, adequate irrigation, integrated pest management, and crop management should be done well. Efforts that can be done is to provide a balanced fertilizer, one with the use of appropriate doses of NPK fertilizer. The research was conducted in Gedangan Village, Grogol District, Sukoharjo Regency in May to August 2017 using Randomized Complete Block Design (RCBD) design with 2 factors of treatment, is the dosage of NPK fertilizer and rice varieties and replicates 4 times. The results showed that the treatment of various doses of NPK fertilizers and rice varieties increased the results of all observation variables, except in the variable of plant height and yield per harvest. While the interaction between the two treatments almost increased the results of all observation variables except for plant height and yield per harvest.</p>

The F1 hybrid sterility in indica/japonica crosses is the major barrier in developing hybrid rice varieties between these two diverse germplasm. The sterility problem in japonica/indica hybrids can be overcome by using wide compatibility genes. The objective of this study was to identify wide compatibility varieties (WCVs) in some tropical japonica rice. Twenty five tropical japonica varieties as male parents were crossed with indica (IR64) and japonica (Akitakomachi) testers as female parents. The crosses were planted following a randomized complete block design with three replications. Varieties having average spikelet fertility of more than 70% with both the indica and japonica testers were rated as WCVs. Result from this study showed that six tropical japonica varieties were classified as WCVs, i.e., Cabacu, Grogol, Kencana Bali, Klemas, Lampung Lawer, and Napa. Hybrid sterility is caused by partial sterility of male and female gametes. The WCVs from the present study can be used in hybrid rice breeding program to solve hybrid sterility in indica/japonica hybrids.

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.

An experiment was conducted at a farmer’s field in Bakergonj Upazilla of Barisal district from July 2014 to October 2014 to study the adaptive performance of six aman rice varieties. The varieties included in the study were BRRI dhan62, BINA dhan7, BINA dhan8, BINA dhan10, BINA dhan11, and Maloti (local). The experiment was laid out in a randomized complete block design with three replications. Variety Maloti produced highest plant height (126cm) and BRRI dhan62 produced least plant height (93cm). Variety BINA dhan7 and BINA dhan11 produced highest LAI, total dry matter (g plant-1). Yield of different rice varieties varied significantly. Variety BINA dhan11 gave the highest yield (5.033 t ha-1) which was statistically at par with that of BINA dhan7 (5.00 t ha-1) and BINA dhan8 (4.50 t ha-1), BINA dhan10 (3.933t ha-1), BRRI dhan62 (4.167t ha-1). The highest grain yields of these varieties were obtained to the highest number of bearing tillers m-2. The lowest grain yield (3.50 t ha-1) and straw yield (4.840 t ha-1) were found in Maloti. The shortest period for first flowering (66 days) was observed in BRRI dhan62. Among the varieties, the longest maturity stage (139 days) was observed in local var. Maloti. While the shortest period was observed in BRRI dhan62 (94.5 days). So, the experiment concluded that BINA dhan11 was the highest performing short duration variety followed by BINA dhan7, while BRRI dhan62 and, BINAdhan8, BINAdhan10 performed better among the short duration varieties respectively during aman season to evade cyclonic effect and for cultivating boro rice in Bakergonj Upazilla of Barisal district.Asian J.

<p align="center"><strong>ABSTRACT</strong></p><p>Talas banana (<em>Musa paradisiaca</em> var. <em>sapientum</em> L.) has a high economic value. However, because of slowly breeding, a quick way of propagation: i.e. in vitro is required.Peatlands inSouth Kalimantan are quite large and has potential to be used for planting area of Talas banana. The acclimatization of seedlings planted on the peatsrequires more fertilizers, considering the low nutrient content of the peats. This study aims to determine the chicken manure and nitrogen-phosphor-potassium (NPK) fertilizer on the growth of Talasbanana acclimatized in peatlands. This study applied a randomized block design (RBD) factorial: (1) the amount of chicken manure (K), namely: k<sub>1</sub> = 5 t ha<sup>-1</sup>; k<sub>2</sub> = 10 t ha<sup>-1</sup>; k<sub>3</sub> = 15 t ha<sup>-1</sup>; k<sub>4</sub> = 20 t ha<sup>-1</sup>, and (2) the amount of NPK fertilizers (P), namely: p<sub>1</sub> = 200 kg ha<sup>-1</sup>; p<sub>2</sub> = 250 kg ha<sup>-1</sup>; p<sub>3</sub> = 300 kg ha<sup>-1</sup>. Therefore, 12 treatments. DITAMBAHKAN TERDAPAT 12 PERLAKUAN. All treatments have 3 replicates. The results of the experiment showed that there was no interaction between doses of chicken manure with NPK.

The F1 hybrid sterility in indica/japonica crosses is the major barrier in developing hybrid rice varieties between these two diverse germplasm. The sterility problem in japonica/indica hybrids can be overcome by using wide compatibility genes. The objective of this study was to identify wide compatibility varieties (WCVs) in some tropical japonica rice. Twenty five tropical japonica varieties as male parents were crossed with indica (IR64) and japonica (Akitakomachi) testers as female parents. The crosses were planted following a randomized complete block design with three replications. Varieties having average spikelet fertility of more than 70% with both the indica and japonica testers were rated as WCVs. Result from this study showed that six tropical japonica varieties were classified as WCVs, i.e., Cabacu, Grogol, Kencana Bali, Klemas, Lampung Lawer, and Napa. Hybrid sterility is caused by partial sterility of male and female gametes. The WCVs from the present study can be used in hybrid rice breeding program to solve hybrid sterility in indica/japonica hybrids.
