The Comparative Study

The comparative study of the soils sample collected from Gudu and Oworoshoki area, Sokoto state and Lagos State was carried out to compare the index properties of soil at shallow soil deposit. The Global Positioning System (GPS) was used to locate the coordinates of the site. Shallow soil samples (disturbed and undisturbed) at different depths (1m, 2m and 3m) were collected from both study areas (Gudu and Oworoshoki). The disturbed samples were collected using hand trowel, digger, hoe and polythene bags while the undisturbed samples were collected using short pipes (samplers) by stroking each pipe into the ground completely with a hammer at each depth. Disturbed and undisturbed soils collected at different shallow depths (1m, 2m and 3m) were taken to the laboratory for natural moisture content, specific gravity, sieve analysis, Atterberg limits and unit weight test. Empirical equations were used for analyzing the soil samples and AASTHO System of classification was used for classifying the soil samples. The results of the test on Gudu soil samples has shown that the soil sample collected at depth 1.0m and 2.0m are nonplastic materials and were classified according to AASHTO standard as A-3 and sample at depth 3.0m as A-4 which is silty soil while Oworoshoki soil samples has shown that Soils from depth 1.0m, 2.0m and 3.0m are nonplastic (NP) because the Plastic Index (PI = 0) is zero and the soil samples are classified as A – 3 according to AASHTO standard.

Fine Tune

The seed production potentialities of selected 20 hybrid rice combination were assessed in this study. Higher seed yield potentiality and earliness in maturity were two of the most important indicators for popularizing hybrid rice variety in Bangladesh. The field performance of the selected hybrid rice combinations were found to vary significantly for different traits except number of total spikelets per panicle showed insignificant variation among the hybrid rice genotypes. The highest number of tillers per plant was recorded in BRRI7A/BRRI31R (17.33) which was followed by BRRI10A/BRRI20R (16.33) and BRRI7A/BRRI20R (16.17). Maximum number of panicles per plant was produced by BRRI7A/BRRI31R (14.00) which was followed by BRRI10A/BRRI31R (13.07), and BRRI11A/BRRI31R (12.47). The highest number of filled spikelets per panicle was produced by BRRI7A/BRRI31R (48.20) which was followed by IR79156A/BRRI31R (47.83) and BRRI7A/BRRI10R (44.63) respectively. The highest value for percent out crossing rate (%OCR) was observed in the combination of BRRI7A/BRRI31R (50.23%) which was followed by BRRI10A/BRRI10R (46.40%). The highest value for grain yield per plant was recorded in BRRI7A/BRRI31R (8.17g) followed by BRRI10A/BRRI10R (7.85 g) and BRRI11A/BRRI15R (7.68 g), respectively. The lowest value for grain yield per plant was found in IR79156A/BRRI31R (3.97 g). Considering comparative study of floral traits, BRRI7A/BRRI31R hybrid rice combination has good commercial prospects but seed production potentiality under Bangladesh conditions needs to be estimated with fine tune.

<p>Micropropagated and stem cutting derived plants of Mulberry (<em>Morus indica</em> L. cv. S-36) were transferred to the similar field conditions. A comparative study was conducted based on morphological parameters and growth characteristics for three consecutive years.  The results demonstrated that micropropagation gave rise to superior clonal populations with respect to number of branches/plant and leaf yield/plant that will be suitable for the mass production of plants.  Thus <em>in vitro</em> grown plants did not exhibit any significant quantitative variation as compared to the conventionally grown plants, indicating the varietal multiplication to be of true-to-type.</p>
