In order to evaluate a number of agro-morphological characteristics in 10 melon population, an experiment based on randomized complete block design with three replications was carried out in two years (2017-2018) at high tunnel condition at Zahak Agriculture Research Station. The relationships among the related traits evaluated using by statistical methods. The combined analysis of variance revealed highly significant differences among landraces in evaluated traits. A highly and significant correlation was observed between fruit width and yield (0.81**). Mean comparison using Duncan?s multiple rang test revealed that maximum yield belonged to landrace Zardeivanaki with 29160 kg/ha. Factor analysis was used for understanding the data structure and trait relations. The factor analysis showed that five factors explained 84% of the total variation among the traits. Therefore, the selection may be done according to the first component and it was helpful for a good breeding program for development of high yielding genotypes also landraces Dargazi, Zardeivanaki and Sabzsooski were placed very closely indicating that the responses of these landraces to be similar to high tunnel cultivation condition.

Experiments were conducted during summer seasons from 1991 to 1994 to find out the effect of winds on early growth of muskmelon. A randomized complete-block design with sheltered and exposed areas as treatments was used. Sensors for air temperature and relative humidity (model HMP35C or model XN217, Campbell Scientific) were placed at canopy height and 3-cup anemometers (model 12102, R.M. Young, Traverse City, Mich.) were 50 cm aboveground. All sensors were connected to CR10 automatic data loggers and recorded hourly average data. Using regression analysis, we found that the accumulative windspeed frequency below threshold (<4 m–s–1) can be used to predict both accumulative hourly heat units of air temperature (GDHT) with R2's more than 0.85 and total muskmelon fresh and dry weight and leaf area index at early growth. Predicted models using accumulative hourly windspeed frequency have R2's >0.80 in sheltered areas. Adding vapor pressure deficit to the model improves the prediction of muskmelon early growth, especially in exposed areas.

ABSTRACT The genetic variability within the crop species Ipomoea batatas is broad, hence, in order to support future breeding programs it is of the utmost importance that germplasm banks be created, conserved, and characterized. Therefore, the objective of this work was to rescue and evaluate the genetic divergence in sweet potato accessions collected in traditional communities of Vale do Ribeira Paulista. Sweet potato samples were collected from quilombos, indigenous villages, caiçaras communities, and small farms. The study was conducted between February 2013 and August 2014 in a randomized block design with three replications. Genetic material included 95 collected accessions and two commercial cultivars. Morphological characteristics of the accessions were evaluated and distances in the genetic distance matrix were estimated by means of multi-category variables, the data being subsequently clustered by the Tocher method. Analysis of the relative contribution of each characteristic and phenotypic correlation of descriptors was also performed. Results evidenced wide genetic diversity among the sweet potato accessions collected in Vale do Ribeira, which were not grouped according to the collection point. The descriptors that contributed more than 60% of genetic diversity included: leaf size, general leaf profile, immature leaf color, petiole pigmentation, predominant branch color, branch secondary color, stem length, cortical thickness, predominant periderm color, and periderm color intensity. Correlations between morphological descriptors was observed in 22.26% of the paired traits.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from December 2013 to May 2014 to evaluate the integrated use of poultry manure with prilled urea and USG for improving the growth, yield and protein content of aromatic Boro rice (cv. BRRI dhan50). The experiment was laid out in a randomized complete block design with three replications. The experiment comprised 14 treatments viz. control (no manure and no fertilizer), recommended dose of prilled urea (115 kg N ha-1), urea super granules (USG) 1.8 g (55 kg N ha-1), USG 2.7 g (80 kg N ha-1), poultry manure (PM) 2.5 t ha-1, PM 5 t ha-1, recommended dose of prilled urea + PM 2.5t ha-1, recommended dose of prilled urea + PM 5 t ha-1, 50% of recommended dose of prilled urea + PM 2.5 t ha-1, 50% of recommended dose of prilled urea + PM 5 t ha-1, USG 1.8 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1and USG 2.7 g + PM 5 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Morphological characteristics, yield contributing characters and yield of aromatic Boro rice (cv. BRRI dhan50) were significantly influenced by integrated use of poultry manure with prilled urea and  USG. USG 2.7 g + PM 5 t ha-1 gave the highest plant height, number of tillers hill-1 and total dry matter production at all sampling dates while their corresponding lowest values were recorded in control. The highest yield contributing characters viz. number of effective tillers hill-1 (13.08), grains panicle-1 (124.26g) and 1000-grain weight  (21.41g) were recorded in USG 2.7 g + PM 5 t ha-1 and the lowest values were recorded in control. The highest grain yield (5.33 t ha-1) and protein content (7.49%) were obtained at USG 2.7 g + PM 5 t ha-1 which was as good as recommended dose of prilled urea (115 kg N ha-1) + PM 5 t ha-1, USG 2.7 g + PM 2.5 t ha-1, USG 1.8 g + PM 5 t ha-1, recommended dose of prilled urea (115 kg N ha-1) + PM 2.5 t ha-1 while the lowest one (2.00 t ha-1) was obtained in control plots. The integrated use of poultry manure (5 t ha-1) with USG 1.8 g (55 kg N ha-1) appeared as the promising practice because of reducing considerable amount of prilled urea or USG in aromatic Boro rice (cv. BRRI dhan50) cultivation in terms of grain yield and grain protein content.Progressive Agriculture 27 (2): 86-93, 2016

Cucumis Melo L

Muskmelon (Cucumis melo L.) is one of the most important vegetable crops in Oman. In the fall of 2004, sudden wilt was observed in muskmelon grown in a field at Sultan Qaboos University, Muscat. The disease was characterized by rapid collapse of vines and muskmelon plants at the fruit production to maturation stage, associated with brown-to-dark brown rotted primary and secondary roots. The disease resulted in death of more than 85% of muskmelon plants in that field. On potato dextrose agar (PDA), with published methods (1), Pythium spp. were consistently isolated from crowns and roots of plants showing wilt symptoms. Further identification of five isolates of Pythium with sequences of the internal transcribed spacer (ITS) of the ribosomal DNA (1) using ITS1 and ITS4 primers produced a nucleotide sequence 806 bp long, which was identical among all isolates. Comparison with sequences deposited at the National Center for Biotechnology Information revealed 100% nucleotide similarity to a previously published sequence (Accession No. DQ381808) of isolate P091 of P. splendens from cucumber from Oman, for which identification has also been confirmed by morphological characteristics. The sequence of one isolate of P. splendens (P222) was assigned GenBank Accession No. EF546436 and deposited at CBS under Accession No. CBS121855. In pathogenicity tests conducted in a greenhouse, P. splendens induced damping-off symptoms on 7-day-old muskmelon seedlings and also reproduced the same wilt symptoms observed in the field when 2-month-old muskmelon plants were inoculated with 3-day-old P. splendens grown in PDA. To our knowledge, this is the first report of association of P. splendens with wilt of muskmelon in Oman. Reference: (1) A. M. Al-Sa'di et al. Plant Pathol. 56:140, 2007.

Ten Napier grass genotypes (accessions) were assessed across 3 locations, Bako, Boneya Boshe and Gute, for forage dry matter (DM) yield, crude protein (CP) concentration, leaf:stem ratio, nutrient composition and digestibility characteristics during 2016 and 2017. The genotypes were evaluated in a randomized complete block design with 3 replications. Mean DM yield was higher for accession ILRI 16804 across all locations followed by ILRI 16801 and ILRI 16800. Leaf:stem ratio, CP concentration and CP and digestible organic matter (OM) yields also varied significantly among genotypes with the highest values obtained for accession ILRI 16804 across all locations, followed by ILRI 16800 and ILRI 16801. Yields of DM, CP and digestible OM and leaf:stem ratio were higher at Boneya Boshe and Gute than at Bako and higher during 2017 than during 2016. The consistently superior performance of ILRI 16804, ILRI 16801 and ILRI 16800 in both years across the 3 sites suggests that these genotypes should be studied further on farms and in differing environments before being recommended for general cultivation in this area. Examining performance with more frequent harvests and feeding studies with livestock would confirm the benefits to be obtained from planting these new accessions.
