The experiment was conducted to determine seeding density and nitrogen fertilizer doses for the MT10 rice variety grown in the winter-spring crop 2015/2016 and the Summer-Autumn crop 2016 in Ninh Thuan. Both experiments were established using a randomized complete block design with three replications. The seeding density experiment was performed in winter-spring season 2015/2016, including density levels of 120, 160, 200 and 250 kg/ha. The nitrogen fertilizer dosage experiment was organized in summer 2016, including 4 levels of 100, 120, 140 and 160 kg N/ha. Other non-experimental elements were identical. The results showed that the highest yield and economic efficiency were for the treatments of 200 kg seed/ha with a nitrogen fertilizer dose of 140 kg N/ha.

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).

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during April to November, 2012 to study the combined effects of Sesbania green manure incorporation with different levels of nitrogen fertilizer on the growth and yield of BINA dhan7. There were five treatments for using Sesbania as pre-rice green manure (GM): Fallow (No GM), GM for incorporation at 40, 50, 60, and 70 days after sowing (DAS). T. Aman was planted after chopping the GM. For T. aman there were 9 treatments: Fallow plot received full dose (180 kg urea ha-1) of N fertilizer while plots with GM received 50 and 75% of recommended N fertilizer. The experiment was laid out in a Randomized Complete Block Design with three replications. The highest grain yield of 5752 kg ha-1 and straw yield of 6654 kg ha-1 were observed in the plot treated with 75%recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The lowest grain yield (4783 kg ha-1) and straw yield (5154 kg ha-1) were recorded with GM incorporated at 40 DAS + 50% RDN. The N content and uptake by the grain and straw were differed significantly due to different treatments and maximum uptake was recorded with the application of 75% recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The overall results indicate that application of Sesbania green manure incorporated at 50 DAS in combination with 75% recommended dose of nitrogen could be considered more effective for BINA dhan7 production DOI: http://dx.doi.org/10.3329/sja.v12i2.21925 SAARC J.

Varietal selection and appropriate placement of nitrogen fertilizer could reduce the magnitude of nitrogen losses to a considerable extent and improve its use efficiency for better grain production. An experiment was carried out during the period from July to December at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to evaluate the effect of variety and nitrogen fertilizer management on the growth and yield of transplant aman rice. The treatments consisted of three varieties viz. BR11, BRRI dhan49 and Binadhan-7, and five nitrogen fertilizer managements viz. two depth of placement of USG (Urea Super Granule) and three split applications of prilled urea. The experiment was laid out in a randomized complete block design with three replications. The results showed that the effect of variety and nitrogen fertilizer management significantly influenced all the yield contributing characters except weight of 1000- grains, non-effective tillers hill-1 and panicle length. The highest grain yield (3.69 t ha-1) was obtained from Binadhan-7. In the case of nitrogen fertilizer management, the highest grain yield (4.32 t ha-1) was found from the 6 cm depth placement of USG. The highest grain yield (4.82 t ha- 1) was observed from the interaction of Binadhan-7 with the 6 cm depth of placement of USG. It may be concluded that Binadhan-7 with 6 cm depth of placement of USG appeared as the promising practice to maximize the yield of transplant aman rice. Res. Agric., Livest.

Studies on the performance of Shusama organic fertilizer on the growth and yield of wetland rice was carried out during the T. aman season. The modern rice variety BRRIdhan 31 was used as test crop. The following eight treatment combinations were tested: T1 = Native nutrient; T2 = Soil Test Base (STB); T3 = 1/3rd of STB + Shusama @ 124Kg/ha; T4 = 1/3rd of STB + Shusama @ 124 Kg/ha as basal and 250 g/decimal at 40 ? 45 DAT; T5 = 25% STB + Shusama @ 124 Kg/ha; T6 = 50% STB + Shusama @ 124 Kg/ha; T7 = 75% STB + Shusama @ 124 Kg/ha; T8 = 100% STB + Shusama @ 124 Kg/ha. The experiment was laid out in Randomized Complete Block Design with 3 replications of each treatment. It appeared from the results that 50% reduction of chemical fertilizer on STB along with Shusama @ 124 Kg/ha may be a good combination of organic and inorganic fertilizer for sustaining soil fertility and increasing T. aman rice.Key words: Organic fertilizer; Growth; Yield; Wetland riceDOI: http://dx.doi.org/10.3329/dujbs.v20i1.8833Dhaka Univ.

The experiment was carried out during the period from January to May, 2018 at Professor Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University to evaluate the effect of phosphorous (P) on yield and yield attributes of BRRI dhan28. The experiment was consisted of seven P doses viz. T0 = without phosphorus (P), T1 = 9 kg P ha-1, T2 = 12 kg P ha-1, T3 = 15 kg P ha-1, T4 = 18 kg P ha-1, T5 = 21 kg P ha-1 and T6 = 24 kg P ha-1 as treatments. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Only the grain yield and biological yield showed significant variations due to the effect of different rates of phosphorous. Others growth and yield attributes varied insignificantly. The result of this experiment showed that the highest grain yield (3.82 t ha-1) and biological yield (10.87 t ha-1) was obtained from 21 kg P ha-1 (T5). There was an increasing trend of grain yield with the increase of phosphorous level up to 21 kg P ha-1 and then it declined. From the result of this experiment it could be revealed that 21 kg P ha-1 gives better result regarding grain yield of HYV rice variety BRRI dhan28 at Batiaghta upazila of southwestern Bangladesh.

Java lemongrass is commonly cultivated in Vietnam for the food industry and traditional medicine. To achieve high productivity, the application of fertilizer is one of the most traditional farm practices and necessary. A single factorial experiment was carried out in a randomized complete block design to investigate the effect of nitrogen fertilizer doses on growth, leaf and essential oil yields of Java lemongrass. Eight treatments were used in this experiment including 0, 15, 30, 45, 60, 75, 90 kg N/ha and applying only 2 tons Komic biofertilizer/ha as control. Fertilizer foundation for treatments 1 - 7 (for 1 ha) included 2 tons of Komix biofertilizer, 60 kg P2O5 and 60 kg K2O. The application of 90 kg N/ha significantly improved the growth of Java lemongrass and increased leaf yield (12.02 tons/ha/3 harvest times) as well as resulted in the highest oil yield (138.1 kg/ha/3 harvest times).

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

ABSTRACT Growth regulators can be used to further retard or inhibit vegetative growth. In this sense, the objective of this study was to determine the effects of age and number of trinexapac-ethyl applications on the growth and yield of sugarcane. The experiment was in a randomized complete block design with four replications. The treatments were in a 3 x 2 + 2 factorial arrangement, where factor A corresponded to the application times of the plant growth regulator (120, 200 and 240 days after bud burst (DAB) of sugarcane) and factor B to the number of applications (one or two applications). In addition, two controls (one with three applications and another application without the regulator) were added. The application of trinexapac-ethyl decreased the number and the distance between buds, height, root volume and sugarcane yield. The sequential application (2 or 3 times) induced an increase in stem diameter and three applications of the product increased the number of plant tillers. The use of growth regulators applied at 240 DAB has reduced plant height, however without changing the number of buds. It can be concluded that trinexapac-ethyl changes sugarcane growth and yield, regardless of season and number of applications.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.
