<p>Intensity and quality of sunlight received by plants during the reproductive period greatly influence the soybean yield and yield components. Growth and seed yield of soybean genotypes at different shade intensities were assessed through research conducted at the Research Station of Kendalpayak, Malang, in the year 2011. Three soybean varieties, namely: Pangrango, Argomulyo, and Grobogan, and twelve soybean promising lines tolerant to shade were tested on four artificial shade intensities, ie without shade (N0), shade of 25% (N1), 50% (N2), and 75% (N3). Placement of treatments in each level of shade was arranged in a randomized block design, replicated three times. Results showed that: shade treatment changed the microclimate under the shading. Shade treatment of 25%, 50%, and 75% caused different stress intensities. Shade intensity of 75% caused an increase in plant height and specific leaf area, a reduction in the number of leaves and leaf area, photosynthetically active radiation (PAR) absorption rate, photosynthetic rate, leaf chlorophyll index, number of filled pods, and seed weight per plant. Number of filled pods was considered effective to be used as a basis for selecting soybean genotypes having high yield in shaded conditions. Plant height and seed weight could be used as an indicator for soybean shade tolerance. Genotype AI26-1114-8-28 and IIj9-299-1-4 were considered as shade-tolerant up to 75% shade based on the stress index tolerance value (ITC).</p>

THIS STudy was aimed to induce genetic variation toward drought tolerance after treatment with EMS as a mutagen to two maize inbred lines and their single hybrid. The experiment was carried out at Abo-Ghraib Research Station, Baghdad during the spring season of 2019. The experiment included three irrigation intervals 7, 9 and 11, four concentrations of EMS (0, 50, 60, and 70 mM) and three maize genotypes distributed in three replications using randomized complete block design (RCBD) with split-split plot arrangement which included three irrigation intervals 7, 9 and 11 days occupied the main plot, while the sub plots included three maize genotypes, and four EMS concentrations which were distributed in sub-sub plots. Results were revealed significant differences among EMS treatments and irrigation interval treatments. The inbred line 5 in control treatment showed a significant increase in days for both anthesis and silking (70.11 and 71.94) days, respectively. Plants of Nahrain hybrid also showed a super performance in plant height, leaf area, and number of rows ear-1, with a mean of 154.47cm, 746.31cm2 and 17.83 row ear-1, respectively. The irrigation intervals of 9 and 11 days were significantly decreased the mean performance of genotypes, compared to the shortest irrigation interval (7 days) which had highest mean in most traits. None treated plants (0 mM EMS) had a significant effect on the performance of most studied traits, except the anthesis and silking time, which gave the highest values under the concentration 60 mM with 69.11 and 70.48 days, respectively. Hybrid plants interacted significantly with the EMS concentration of 0 mM producing the maximal means of plant height and leaf area (169.56cm and 759.78cm2 respectively). On the other hand, the hybrid was significantly interacted with the shortest irrigation interval in the mean traits of plant's height and leaf area (163.50 cm and 757 cm2, respectively). The triple interaction between hybrids, shortest irrigation interval and EMS concentration of 60 mM had significantly increased leaf area reached 769.67cm2, meanwhile the triple interaction between hybrid plants, shortest irrigation interval, and the EMS concentration of 0 mM recorded the highest value of plant yield (199.67g). It can be concluded from the current study that the genotypes differed in their response to 9 and 11 days irrigation intervals, with a negative effect of the later interval on the vegetative and yield traits of maize compared with shorter irrigation interval.

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

Abstract The experiment was conducted at Regional Horticulture Research Station, Lebukhali, Patuakhali and were evaluated the genotypic performance like yield and yield traits of seventeen (17) country bean genotypes collected from Patuakhali region. In this area, country bean yield is very low, that why we need to identify high yielding country bean genotypes in Patuakhali region. The experiment was laid out in an augmented block design. Seventeen country bean lines viz., LPPK001 to LPPK017 and four check variety viz., BARI Sheem-1, 6, 7 and IPSA Sheem-2 were used for this trial. A lot of variability was observed such as plant height, pod length, pod breadth, pod weight, No. of pod plant-1, yield plant-1, 100 seed weight and yield. The pod length ranged from 20.4-7.62 cm, pod breadth range from 4.83-1.41 cm and pod weight ranged from 13.28-5.08g. The longest pod (20.4 cm), maximum pod breadth (4.83cm) and the premier pod weight (13.28 gm) were found in BARI Sheem 6, LPPK012 and LPPK002 respectively. The highest yield (18.73 t/ha) obtained from the line LPPK016 and minimum in the line LPPK 003 (5.43 t/ha). Among the 17 tested lines and 4 checks; 15 were green in colour, and IPSA Sheem 2 was light green, LPPK011 was purple green and LPPK001 and LPPK014 were creamy- white in colour. The wide variations in phenotypic level among the genotypes LPPK001, LPPK005, LPPK015, LPPK016, and BARI Sheem 7 can be potentially used for more production in Patuakhali region, ultimately it will increase the farmers’ incomes level.

<p class="Abstrak"><span>Cowpea [<em>Vigna unguiculata</em> (L.) is more tolerant to drought and acid soil, compared to the other leguminous crops. A total of 150 cowpea germplasm accessions were grown at Muneng Research Station (Probolinggo) during dry seasson of 2014, using a randomized block design, with two replications. Each accession was planted in two rows, of 4 m. Among the total accessions they varied in qualitative and quantitative traits. Most of the accession had ovate leaf shape, purple flower color, cream color of mature pod, and brown to yellowish grain color. Grain yield had a high phenotipic and genotypic coefficient of variation. Low phenotipic and genotypic coefficient of variation was shown on days to 50% flowering and days to physiological maturing. Of the eight variables characterizing the cowpea accessions 64.2% could be explained by three factors. The first factor related to grain yield components (number of fertile nodes, number of branches, and grain weight), second factor associated with crop cycles (date of flowering and harvesting), and the third factor associated with the supporting factors (plant height, pod length, and number of grains per pod). The cowpea germplasm could be divided into three groups. Date of flowering and pod maturing were a determinant variable discriminant function. Group I consisted of 70 accessions, dominated by accessions with early maturing, medium plant height, long pod, high number of grains per pod and high grain yield. Group II consisted of 47 accessions with medium pod maturing, short plants, short pod, low number of grains per pod and low grain yield. Group III consisted of 33 accessions, characterized by medium maturing, high plant, short pod, high number of grains per pod and high grain yield. Accessions of cowpea in group I and III have a high yield and are prospective for further utilization.</span></p>
