Np Fertilizer

Nitrogen and phosphorus (NP) are two most important essential nutrients promoting plant growth and yield traits of all crops. NP fertilizers are easy to use and quick in releasing nutrients. A field experiment was conducted at Oilseed section, Agriculture Research Institute, Tandojam to determine the effects of different doses of NP fertilizers on the time of maturity, vegetative growth and yield and yield related traits of sunflower variety HO-1. The six NP fertilizer levels viz. T1 = 0-0 (control), T2 = 80-40, T3 = 100-50, T4 = 150-50, T5 = 120-50 and T6 = 120-75 NP kg ha-1 were set in a randomized complete block design (RCBD). The results revealed that all the parameters of sunflower were significantly affected (P < 0.05) by different NP fertilizer doses. It was observed that maximum 184.25 (cm) plant height, 6.66 (cm) stem girth, 28.19 (cm) head diameter, 1161.92 seeds head-1, 90.33 (g) seed index and 2172.00 (kg ha-1) seed yield was achieved by applying 150-50 NP fertilizer kg ha-1. It was also noted that 150-50 NP kg ha-1 promoted the sunflower crop to mature early by enhancing vegetate growth. The poor performance for all growth, yield and maturity parameters were observed in the treatment where no NP fertilizer was applied (control). It was concluded that growth and seed yield was increased by increasing the application of NP fertilizers up to 150-50 NP kg ha-1 and thus recommended to get better growth and yield performance of sunflower crop in locality

AbstractBiochar produced from pyrolysis of organic materials has been found to improve plant growth by improving the physical and chemical characteristics of the soil as well as enhancing the sequestration of carbon dioxide that would release into the atmosphere through the decomposition of organic residues. However, there is scanty information on the methods used to apply biochar in order to optimize the benefits of biochar use for agricultural production. In view of this, a field study was carried out at the experimental field of CSIR – Soil Research Institute, Kumasi, to assess the effect of method of biochar application on the growth, yield and nutrient uptake of cowpea (Vigna unguiculata) in a moderately acidic sandy Ferric Acrisol. The experiment was set up using a Randomized Complete Block Design with three replications. The treatments imposed were as follows: control, broadcasting, spot and ring methods of application. The parameters assessed included growth and yield data as well as nitrogen and phosphorus uptake in shoots and grains. The data collected were subjected to analysis of variance using Genstat 12th edition. The results showed that the spot and ring methods of application significantly enhanced height, girth, nodule number and dry weight, shoot biomass and grain yield as well as nitrogen and phosphorus contents in shoots and grains when compared with the broadcasting method and control. This study therefore recommends the spot and ring methods of biochar application for adoption in cowpea production for enhanced growth, yield and nitrogen and phosphorus uptake.

Aims: The field experiment was conducted to evaluate new sesame varieties for growth and yield performance. Study Design: A randomized completely block design (RCBD) with four replications was used for the experiment. Place and Duration of Study: The study was conducted during the Deyr season (September-November) 2016 at the experimental farm of Somali Agriculture Technical Group (SATG), Afgoye, Somalia. Methodology: Growth and yield characters of the varieties were measured during the trial. A complete of six sesame varieties was used for the trial. The new varieties were Setit, Yemeni, Nigerian, Humera and Indian while a local variety, Dunyar, was used as a control. Results: Results from the experiment revealed that growth parameters such capsule length, number of branches per ∙plant, number of capsules per plant and number of seeds per capsule were significantly different among the varieties. Yield performance of the sesame varieties was also significantly different. It was observed that Humera variety showed the highest seed yield of 2.82 ton per hectare while the Indian variety has given the lowest seed yield of 0.67 ton per hectare. The highest straw yield of 3.45 ton per hectare was recorded for Local variety while the lowest straw yield of 2.76 ton per hectare was observed in Setit variety. Likewise the highest biological yield of 6.18 ton per hectare was observed at Dunyar variety while the lowest biological yield of 3.61 ton per hectare was recorded for Indian variety. Conclusion: The growth and yield of these particular varieties did not outperform the local variety, thus, future studies would be essential to look for other alternative methods and cultivars that would help increase the productivity.

An experiment was carried out at the research farm of Patuakhali Science and Technology University (PSTU) during the period from November 2010 to April 2011 to study on growth and yield performance of cowpea cv. BARI Falon-1 under different treatment of GA3 as foliar spray to investigate the responses and most optimum level of gibberelic acid regarding growth and yield of Falon that are suitable to cultivate in coastal region of Bangladesh. Among the GA3 treatments, 33.33 ppm GA3 produced significantly the tallest plant (61.07 cm), maximum leaves and branches plant–1 (28.50 and 19.73, respectively), higher LAI (1.10) and higher TDM plant–1 (81.95 g) comparatively than that of other GA3 levels while control had lower on the above characters. Growth characters such as CGR, RGR and NAR had also higher (0.99 and 1.65 gm–2 day-1 for CGR, 0.43 and 0.72 gm–2 day–1 for RGR and 0.027 and 1.275 mg cm2 day–1 for NAR) in 33.33 ppm GA3 at the stage between 30 to 60 DAS and 60 to 90 DAS, respectively Yield contributing characters Among other observation of yield and yield contributing characters, 33.33 ppm GA3 further registered the maximum pods plant–1 (11.50), longest pod (17.05 cm), higher weight fresh (3.78 g) and dry pod (1.99 g), higher weight of 100–seed (12.25), seed yield (18.57 g plant–1 and 2986.72 kg ha–1) and higher HI (22.45%). These results also showed that GA3 up to 33.33 ppm signifciantly developmend morpho–physiological, growth, yield and yield contributing characters and thereafter all the data decreased due to its destructive effect of higher GA3 levels. So, considering the above observation it could be suggested that GA3 @ 33.3 ppm would be appropriate doses of GA3 for obtaining the better produciton of BARI Falon-1 under resion.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22196 J.

Aims: This study aimed to investigate the interaction effect of nitrogen and phosphorus on curd yield and seed production of cauliflower. Study Design: The experiment was laid out at a randomized complete block design with three replications. Place and Duration of Study: Research farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, from September 2016 to March 2017. Methodology: The experiment consisted of two factors comprising three levels of nitrogen (270, 220,170 kg ha-1) and three levels of phosphorus (160,130,100 kg ha-1) with control of each nutrient. There were 10 treatment combinations resulting in 30 unit plots where each plot had two rows of 6 plants. Nitrogen and Phosphorus fertilizer were applied as per treatment in the form of Urea and TSP as a top dressing in two equal splits at the time of transplanting and 15 days after transplanting. Results: All the characters related to growth and yield of cauliflower showed significant variation by nitrogen and phosphorus levels at different days after transplanting. Among the different treatment combinations, N270P160 produced maximum plant height (50 cm), leaf area (700 cm2), plant weight (1003 g), curd diameter (18.3 cm), marketable curd weight (601 g) and marketable curd yield (18.5 t) at harvesting compared to control where nitrogen and phosphorus were not used. Moreover, the largest number of leaves (21.3) and curd weight (346 g) was observed by treatment combinations N220P160 at harvesting. For seed production, the highest number of siliqua plant -1 (1461), 1000 seed weight (4 g), seed yield plant-1 (41.1 g) seed yield ha-1 (1.5 t) and germination (97.7%)was also found from N270P160while the maximum number of seeds siliqua-1(20.5) was revealed by N220P160 compared to control treatment. Considering a different point of view, treatment combinations N270P160 can be marked more convenient for cauliflower production than others. Conclusion: It is concluded that the combinations of nitrogen (270 kg ha-1) and phosphorus (160 kg ha-1) would be appropriate for curd yield and seed production of cauliflower.

Row spacing and seed rate are management practices that affect flax seed yield. Hence to find out the optimum quantity of seed rate and spacing for higher production in irrigated linseed, the present experiment was conducted under AICRP on Linseed, College of Agriculture, Nagpur during the Rabi Season of 2019-20. The Experiment was laid out in Factorial Randomized Block Design with three replications in which Factor A consist of two spacing i.e. T1 - 30 cm and T2 - 45 cm and Factor B includes four seed rate S1- 10 kg/ha, S2- 15 kg/ha, S3- 20 kg/ha, S4- 25 kg/ha. Results showed significant effects of seed rates and spacing on all growth and yield attributes, which reflecting the importance of seeding rate and spacing for linseed. Maximum plant height was recorded after using the seed rate at 25 kg/ha (S4) and with 30cm spacing (T1) which was at par with seed rate 20 kg/ha (S3). The other growth parameters like number of branches, number of capsules per plant and test weight was found higher in the treatment having the seed rate of 10 kg/ha (S1) and in the spacing of 45cm (T2). Seed yield of linseed was recorded highest by using the seed rate at 15 kg/ha, which was at par with at the seed rate of 20 kg/ha and in the closer spacing of 30cm between rows i.e. 9.15% more as compare to row spacing of 45cm. Gross monetary returns, net monetary returns and B:C ratio was also recorded maximum in the seed rate of 15 kg/ha and with 30cm row spacing. It is concluded that advancement in seed rate by lowering down up to 15 kg/ha increases the productivity and profitability of linseed.

A field experiment was conducted at Instructional-cum-Research (ICR) Farm, Assam Agricultural University, Jorhat during Rabi seasons of 2016-17 and 2017-18 to study the response of niger to different levels of nitrogen, phosphorus and potassium as well as sulphur on growth, yield and oil content of niger. The experiment was laid out in Factorial Randomized Block Design with three replications. The treatments comprised of three NPK levels viz., F1 (20-10-10 kg N-P2O5-K2O ha-1), F2 (25-12.5- 12.5 kg N-P2O5-K2O ha-1), F3 (30-15-15 kg N-P2O5-K2O ha-1) and three S levels viz., S1 (no sulphur), S2 (10 kg S ha-1), S3 (20 kg S ha-1). Application of F3 (30-15-15 kg N-P2O5-K2O ha-1) and S3 (20 kg S ha-1) recorded maximum and significantly higher seed yield (q ha-1), oil content (%), oil yield (q ha-1) as well as growth and yield attributing parameters viz., plant height, number of leaves plant-1, number of branches plant-1, number of capitulum plant-1 and number of seeds capitulum-1 during both the years. Test weight was not influenced significantly during both the years. Interaction effects of NPK (F) and sulphur (S) were found to be not significant in respect of growth and yield attributing characters in both the years. In case of seed yield (q ha-1) and oil yield (q ha-1) interaction effect were found to be significant in both the years.The highest gross return (Rs. 23,905.00 in 2016-17 and Rs. 22,400.00 in 2017-18) and net return (Rs. 11,184.86 in 2016-17 and Rs. 9679.86 in 2017-18) were recorded by F3S3 in both the years. In case of benefit-cost ratio, the higher value (1.88 and 1.76, respectively) was recorded with F3S3 during 2016-17 and 2017-18.

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.

Kenaf is a multi-purpose crop with numerous industrial uses. Its production is constrained by poor cultural and agronomic practices which reduce yield. Inappropriate spacing among others could result in low yield. Effect of plant spacing on growth and yield of kenaf was investigated in Ibadan, Nigeria. Kenaf seed was sown (2 plants/stand) at three plant spacing: 50×15, 50×20, 50×25 cm was assessed for seed and bast fibre yields using randomized complete block design (RCBD) with three replicates. The analysis was done using statistical analysis system (SAS). Plant spacing differed significantly for bast fibre and seed yields. Highest bast fibre yield (0.9±0.03) and seed yield (0.5±0.01) were obtained at 50×20 cm and 50×25 cm spacing, respectively, while the lowest bast fibre yield (0.7±0.01) and seed yield (0.3±0.01) were obtained at 50×15 cm spacing. Spacing of 50 × 15 cm and 50 × 20 cm are appropriate when planting for fibre while 50 × 25cm is appropriate for seed production. Keywords: Kenaf, Spacing, Fibre and Seed yield.

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under  coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3)  and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018
