The objectives of the study were to assess the variability of growth contributing characters of 50 okra (Abelmoschus esculentus L.) accessions and their interrelation effects on the yield of green pods. The experiment was undertaken at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from February to May, 2002. There was a wide range of variation for spread of plant (43.73 cm), height of plant (80.90 cm) and length of petiole (12.31 cm). Moderate variation for number of nodes per plant (14.58), number of leaves per plant (24.51 at 80 DAS), length of leaf (12.20 cm), breadth of leaf (13.05 cm); and lesser variation for number of primary branches per plant (1.57) was observed. The yield of green pod varied significantly and ranged from 4.39 t/ha (accession 19) to 12.77 t/ha (accession 69) with the average value of 7.86 t/ha. Number of primary branches per plant, which showed a lesser range of variation, recorded the highest genotypic co-efficient of variation (GCV= 26.56%) and also the highest phenotypic co-efficient of variation (PCV = 32.37%). A moderate GCV and PCV were recorded in case of length of petiole (GCV = 14.24% and PCV = 15.95%), spread of plant (GCV = 12.00% and PCV = 13.06%), breadth of leaf (GCV = 9.81% and PCV = 12.41%) and length of leaf (GCV = 9.53% and PCV = 13.35%). These characters suggested the existence of justifiable genetic and phenotypic distance among different accessions. Correlation co-efficient between yield and growth contributing parameters indicated that yield of green pod had highly significant positive association with the number of nodes per plant. Path analysis of different growth contributing parameters showed that number of nodes per plant directly contributed towards the yield of green pod. Key words: Okra accessions, variability, growth parameters, GCV, PCV, path analysis. doi:10.3329/jard.v6i1.1654 J Agric Rural Dev 6(1&2), 25-35, June 2008

In order to assess the variability of yield contributing characters of 50 okra accessions and their interrelation effects on the yield of green pod a field experiment was undertaken at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh during the period from February, 2002 to May, 2002. A wide range of variation was observed in case of weight of green pod per plant (105- 281g), days to first flowering (40-52days) and weight of individual green pod (14-26g). Moderate variation for length of green pod (12-19cm), number of green pods per plant (6-11) and yield of green pod (4-13 t/ha), lesser variation for percent of dry matter content (5-8%), number of ridges per green pod (5-9) and diameter of green pod (1-2cm) was observed. The highest genotypic coefficient of variation was observed in case of yield of green pod (GCV= 23.22%) followed by weight of green pod per plant (22.24%), weight of individual green pod (18.68%), number of ridges per green pod (13.49%), number of green pod per plant (10.84%), dry matter content of green pod (10.48%), diameter of green pod (6.90%) and length of green pod (6.24%). These characters suggested the existence of justifiable genetic distance among different cultivars. Correlation coefficient indicated that yield of green pod had highly significant positive association with weight of green pod per plant and weight of individual green pod. Path coefficient analysis showed that the weight of green pod per plant and weight of individual green pod were directly contributed towards the yield of green pod. Key words: Okra, accession, variability, yield.

The experiment comprising 30 okra (Abelmoschus esculentus) genotypes were grown and analysed for yield and its attributing traits at the Department of Vegetable science, Kumarganj, Faizabad during Zaid (2011) period. All the characters studied showed a wide range of variation. The variability for yield among the accessionsevaluated was also remarkable. The magnitude phenotypic coefficient of variation was higher than genotypic coefficient of variation for all traits. Both phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were high for plant height (11.10 and 10.60, respectively). Fruit weight exhibited low value of GCV (2.31) and PCV (4.74) and likely to show less response under selection. High heritability (91.3) with high genetic advance (26.74) was recorded for plant height, whereas, ridges per fruit had high heritability (97.0) with moderate genetic advance (18.45). This study aimed to evaluate okra genotypes for variability with a view to providing information on the development of high yielding genotypes to meet the growing food demand of the populace.

Screening for Fe deficiency tolerance in okra (Abelmoschus esculentus) Bangladeshi genotypes (‘BARI-1’, ‘Local variety’, ‘Orca Onamica’, and ‘Prince’) were studied based on different morphological and physiological parameters. Number of leaves, shoot height and weight were significantly reduced in ‘Orca Onamica’ and ‘Prince’, whereas ‘BARI-1’ and ‘Local variety’ did not show prominent decrease in the aforesaid growth parameters under Fe deficiency. Again, ‘Orca Onamica’ and ‘Prince’ showed significantly decreased root length and root biomass under Fe deficiency. In contrast, these parameters were unchangeable in ‘BARI’-1 and ‘Local variety’ in Fe shortage compared to controls. Furthermore, Fe deficiency caused severe decrease in chlorophyll (a and b) and Fe concentrations in leaves of ‘Orca Onamica’ and ‘Prince’ grown on hydroponic culture. In contrast, chlorophyll (a and b) and Fe concentrations were not significantly decreased in ‘BARI-1’ and ‘Local variety’ due to Fe deficiency. Based on these findings, tolerance to Fe deficiency in these okra cultivars can be categorized as: tolerant (‘BARI-1’ and ‘Local’), and sensitive (‘Orca Onamica’ and ‘Prince’). The ranking can be applied in plant breeding program and may have great advantage over conventional methods. This study also demonstrates the effectiveness of hydroponic culture as an efficient method to screen Fe-efficient crop plants.

Character association and path analysis in sixty genotypes of brinjal was studied for 17 important characters. The character association studies revealed that the total yield per plant had significant and positive association with plant height (0.385), plant spread (0.660), number of primary branches (0.545), stem girth (0.539) at 90 days after transplanting (DAT), early yield per plant, number of fruits per plant and fruit diameter. While it was negatively and significantly associated with days to first flowering (-0.302 and -0.230), days to 50 per cent flowering (-0.272 and 0.229) and days to first fruit maturity (-0.164 and -0.168) at both genotypic and phenotypic level. Narrow differences between the genotypic and phenotypic correlation coefficients were observed for various traits in the present findings. This indicates the lesser influence of the environment in the expression of these traits and presence of strong inherent association among the traits. Path analysis studies revealed that significant positive association at genotypic level among the traits viz., plant height (0.235), leaf area (at 90 DAT) (0.228), days to first fruit maturity (0.162), number of fruits per cluster (0.280) and early yield per plant (1.903) had exhibited true association with direct effect on yield per plant. The direct selection for these traits would be rewarding for improvement in the total yield per plant.

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.

<strong>Growth Analysis of Rhizophora stylosa Griff. Seedlings in Mangrove Rehabilitation Area of Tanjung Pasir, Tangerang.</strong> Mangrove rehabilitation is urgently needed as an effort to preserve coastal plant ecosystems which are decreasing in Indonesia. It requires the preparation of good seedlings to support the rehabilitation efforts. The seedling of Rhizophora stylosa is suitable for being able to well adapt to the wide range of salinity and illumination. Research on the growth of R. stylosa seedlings was conducted in degraded mangrove areas in the coastal region of Tanjung Pasir, Tangerang, from August to November 2005. This research analyzes the growth patterns R. stylosa seedlings in two habitat types, i.e. the pond dikes and the green belts. A total of 100 seedlings were planted in each habitat with a spacing of 0.5 m. Seedling growth parameters such as the percentage of survival, height and diameter of the stem, and number of leaves were measured monthly. Twoway ANOVA analysis was conducted to determine the overall differences in the parameters between locations and time of observation, as well as its interaction. The results showed the percentage of survival of seedlings planted in the green belts was higher than in the pond dikes (p &lt;0.05), while the growth of the height and diameter of the seedlings planted in the pond dikes was higher than those planted in the green belts. The number of leaves of seedlings planted in both habitats was not significantly different. The regression equation between seedling height (X) and stem diameter (Y) showed a high correlation (p &lt;0.01) in the green belts, which is Y = 0,018X + 0.746 (R = 0.606). A strong correlation was found between stem height (X) and the number of leaves (Y) for the seedlings planted in the pond dikes by the regression equation Y = 0,156X - 2.968 (R = 0.501).<br /><br />

In this study the effect of superior politics on frontline employees' behavioral and psychological outcomes was examined using data collected from 4- and 5-star hotels in Northern Cyprus. The research hypotheses were tested using LISREL 8.54 through path analysis. The model test results indicated that scarce resources are a significant determinant of superior politics. In addition, path analysis results showed that superior politics and scarce resources have a significant negative association with subordinate performance. The model test findings also demonstrated that superior politics and scarce resources are negatively associated with job satisfaction. This research, however, failed to uncover a significant positive association between subordinate performance and job satisfaction. Similarly, scarce resources and subordinate performance did not have significant associations with job commitment.

The purpose of this study was to determine the effect of spacing on the growth and yield of spinach plants with hydroponic NFT (Nutrient Film Technique) and to determine the most effective spacing and spinach results of hydroponic NFT plant growth. This study uses a Completely Randomized Design (CRD) consisting of four treatment spacing, namely 5 cm, 10 cm, 15 cm and 20 cm. Each treatment uses the same number of plants as 15 plants in one gutter. The study was conducted for 20 days. The parameters observed were plant height, number of leaves, fresh weight, dry weight, root length, and stem diameter. High parameters and number of leaves are measured every two days, while parameters of fresh weight, dry weight, root length, and stem diameter are measured after harvest on the 20th day. For the final value obtained from the calculation of plant height growth parameters, namely JT5 (27.45), JT10 (32.45), JT15 (33.22), and JT20 (32.94). And for the final value obtained from the calculation of the number  leaf growth parameters, namely JT5 (11.21), JT10 (12.19), JT15 (12.51), and JT20 (12.17). While the final value of crop yield parameters for root lengths is JT5 (28.06), JT10 (30.43), JT15 (31.36), JT20 (30.70). For the stem diameter the average value obtained is JT5 (0.72), JT10 (8.84), JT15 (0.90), JT20 (0.85). For fresh weight of plants, the average values ??obtained are JT5 (182.40), JT10 (208.24), JT15 (215.07), JT20 (210.76). And for dry weight, the average value obtained is JT5 (9.51), JT10 (13.52), JT15 (15.05), JT20 (13.71). It can be concluded that from the results of the ANOVA analysis, the treatment of 15 cm spacing had the best results and the spacing of 5 cm showed the lowest results in each treatment observed.
