Pagani J. Molinari E. Giardina A. Di Benedetto <p>Pot ornamental plant productivity is related to the environmental growth facilities but negatively affected by the pot root restriction syndrome. Most ferns showed a lower relative growth rate and long production cycles (24 months or more) for which growers use small pots to increase yield per unit area of greenhouse. The aim of this work was to analyze growth changes in response to different pot volume in plants of <em>A. nidus avis</em> spore-propagated under the hypothesis that it would play a role as an abiotic stress which decrease commercial productivity. Our results showed that the use of big pots increased fresh and dry weight and frond area (the main aesthetic trait). When growth parameters were performed, a higher the frond appearance rate (RLA), the frond area expansion (RLAE) and the frond thickness (SLA) were found in 1500 cm<sup>3</sup> pot as well as the relative growth rate (RGR) and the net assimilation rate. The use of biggest pot for fern cropping stimulated biomass accumulation through a higher capacity to initiate and expand fronds, to increase photosynthetic rates and change photo assimilate partitioning which favor shoots. From the grower´s point of view, our results suggested that higher yields of <em>A. nidus avis</em> fern would be reached decreasing root restriction, that is, to use the biggest pot volume from the early transplant from plug trays.</p> 2020-09-07T00:00:00+00:00 ##submission.copyrightStatement## Economics of Turmeric Production in Sri Lanka: An Empirical Analysis in Major Turmeric Growing Districts 2020-09-29T06:59:01+00:00 A. A. S. L. Abeynayaka A. M. K. R. Bandara A. I. Y. Lankapura P. R. Idamekorala <p><strong>Aims: </strong>Turmeric occupies a prominent position among the commercially grown spices in Sri Lanka. However, due to various constraints the performance of turmeric production is not to the expected level. The present study attempts to determine the economics of turmeric cultivation and the problems perceived by the growers related to production and marketing of turmeric.</p> <p><strong>Study Design:</strong>&nbsp; Multistage sampling design.</p> <p><strong>Place and Duration of Study: </strong>The study was conducted in the major turmeric growing administrative districts in Sri Lanka namely Kurunegala, Kegalle, and Kandy during the year 2016-2017.</p> <p><strong>Methodology:</strong> Both primary data, mainly from a field survey, and secondary data were utilized in the study. Descriptive statistical methods, seasonal price index, coefficient of variation of price, financial and constraint analysis techniques were used in data analysis.</p> <p><strong>Results:</strong> The average Benefit Cost Ratio of 2.08 and higher net returns indicate that turmeric production was found to be a profitable venture in the study area. The results indicated the existence of higher price variations of turmeric in the study area between the harvest and the lean periods. Moreover, seasonality of turmeric production was identified as a main cause of variation in price of fresh turmeric. The results of the constraint analysis revealed that lack of knowledge on proper agricultural practices, non-availability of labor, price volatility and shortage of quality planting materials were the top four constraints perceived by the farmers.</p> <p><strong>Conclusion:</strong> The results of this investigation show that the turmeric production is profitable in the study area, and suggest to offer frequent training and awareness campaigns for all the turmeric growers to facilitate the use of improved cultivation practices.</p> 2020-09-19T00:00:00+00:00 ##submission.copyrightStatement## Effect of Phosphorus and Boron on the Growth and Yield of French Bean 2020-09-29T06:58:59+00:00 F. M. Jamil Uddin Mohammad Hadiuzzaman Harun Or Rashid Saedy Karim <p>An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, and Mymensingh to study the effect of phosphorus and boron on the growth and yield of var. BARI Jharsheem-3 along with French bean during November 2017 to March 2018. The experiment was comprised of two factors involving number of levels viz. phosphorus had four levels &nbsp;15, 20, 25 and 35 kg ha<sup>-1</sup> and four levels of boron <em>viz.</em> 0, 0.5, 1.0 and&nbsp; 1.5 kg&nbsp; ha<sup>-1</sup>. Triple super phosphate and Borax were used as source of phosphorus and boron, respectively. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results exhibited that yield and its contributing characters were significantly influenced by the phosphorus and boron applications. The experimental findings revealed that highest&nbsp; number of pods per&nbsp; plant (4.95), pod length (13.06 cm), number of seeds per pod (4.34), and 1000-seed weight (427.99 g), seed yield (1.40 t ha<sup>-1</sup>), stover yield (1.76 t ha<sup>-1</sup>), biological yield (3.16 t ha<sup>-1</sup>) and harvest index (46%) were recorded under phosphorus level at 25 kg ha<sup>-1</sup>. The experimental findings also revealed that the highest number of pods per plant (4.91), pod length (14.45 cm), number of seeds&nbsp; per pod (4.36), and 1000-seed weight (427.22 g), seed yield (1.39 t ha<sup>-1</sup>), stover yield (1.68 t ha<sup>-1</sup>), biological yield (3.07 t ha<sup>-1</sup>) and harvest index (45.27 %) were recorded&nbsp; under boron level at 1.5 kg ha<sup>-1</sup>. In case of&nbsp; interaction of phosphorus and boron, the highest number of pods&nbsp; per plant (5.18),&nbsp; pod length (14.35 cm), number of seeds pod<sup>-1</sup> (4.84), and 1000-seed weight (427.19 g), seed yield (1.86 t ha<sup>-1</sup>), stover yield (2.05 t ha<sup>-1</sup>), biological yield (3.91 t ha<sup>-1</sup>) and harvest index (47.57 %) were recorded under P level at 25 kg&nbsp; ha<sup>-1</sup>&nbsp; and B level at1.5 kg ha<sup>-1</sup>. So it may be concluded that 25 kg P ha<sup>-1</sup> and 1.5 kg B ha<sup>-1</sup> could be applied to obtain higher yield of bean.</p> 2020-09-25T00:00:00+00:00 ##submission.copyrightStatement##
