Journal of Applied Sciences , 2001,
Abstract: The experiment was conducted at Z.A. Bhutto Agricultural College, Dokri Larkana, Sindh, Pakistan in experimental design of RCBD, replicated four times in net plot size of 3m x 5m, where 74078-1, ICPL-4, Local check, ICPL-2, ICPL-6, ICPL-84, T-21, ICPL-150 pigeonpea varieties/lines were planted for growth and yield potentials. Among the tested cultivars ICPL-6 was observed as dwarf and appeared to be superior one by recording maximum branches, having early maturity, and attempted maximum number of pods and seed index. ICPL-6 also proved itself as high yielding pigeonpea cultivar by recording 2166.70kg grain yield-ha. Thus, it is recommended the ICPL-6 pigeonpea cultivar should be grown for early maturity and high potential yield.
Rice Ratooning Management
F.C. Oad,Pompe Sta. Cruz,N. Memon,N.L. Oad
Journal of Applied Sciences , 2002,
Abstract: The ratooning is the ability of the plant to regenerate new tillers from stubbles of the main crop. Though the crop thought to be the same, there may be variation in the physiological parameters between the main and ratoon crop. For example panicle development and heading are more uneven in ratoon than that of the main crop. The ratoons vary in their chemical composition according to the node number and position. The general low yield obtained from the ratoon crop is believed to be mainly due to the reduction in number of productive tillers and short growth duration. Although the yield contributing factors like plant height, leaf area, leaf canopy, panicle length, growth duration, cutting height of the stubble etc. are largely governed by the genetic make-up of the plant. Under various cultural practices cutting height of the main crop stubbles is correlated with yield of the ratoon crop, number of auxiliary buds and productive tillers. Also cutting height is correlated with regrowth potential or ratoon vigour, nodal and basal tillers, ratoon rating and ability, uniform growth and maturity, filled spikelets and missing hills. Application of nitrogen fertilizer is considered probably the most important single nutrient elements in growth and yield of ratoons. The rice ratooning offers an opportunity to increase cropping intensity per unit of cultivated area because a ratoon crop has shorter growth duration than the main crop. In addition, ratoon crop may be grown with 50% less labor. Neither land preparation nor planting is needed and the crop uses 60% less water than the main crop. The yield of the ratoon crop may be achieved by 50% of the main crop, if crop management practices are used efficiently.

Journal of Animal and Veterinary Advances , 2012,
Abstract: A total of 24 matured, parous, clinically sound West African dwarf goats aged 3-5 years were used to study the effect of human menopausal gonadotrophin (Pergonal ) and prostaglandin on leucocyte variations. The goats were divided into three groups of eight goats in each group identified as T1 (Control), T2 human menopausal gonadotrophin treated goats, T3 prostaglandin treated goats. The results show that total leucocyte count consistently increased from pre-treatment to 48 h post-oestrus in HMG-treated goats. There was no significant difference (p>0.05) in Dinoprost tromethiamine induced and natural oestrus. Neutrophil percentage was more during superovulatory oestrus followed by pre-treatment value. However, lymphocyte value was high during 48 h. Superovulatory oestrus, whereas in Dinoprost treated groups neutrophil was more during pre-treatment, but the difference was not significant (p>0.05) between treatment groups. The monocyte, eosinophil and basophil values were similar (p>0.05). The results of this study, indicate that HMG and prostaglandin treatments were not detrimental to the leucocyte count of goats.

Journal of Animal and Veterinary Advances , 2012,
Abstract: A total of 18 parous, healthy and cyclically sound 2-3 years old West African dwarf goats were used to study the effect of repeated super-ov treatment on superovulation and embryo recovery rate. The goats were divided into 3 treatment groups identified as T1, T2 and T3 consisting of 6 goats in each group. T1, the control was administered with physiological saline, T2 administered with super-ov regarded as Initial treatment and T3 regarded as repeated administration of super-ov. The results show that the superovulatory response (CL) during initial and repeated stimulation averaged 7.57 0.52 and 6.85 0.48, respectively. The higher embryo recovery 78.00 0.08% in repeated group differed significantly (p<0.05) from initial super-ov treatment 45.00 0.06% and the control group 30.00 0.02%. The lower number of embryos and transferable embryos of 4.00 0.60 and 3.75 0.85, respectively in the initial super-ov treatment than to second stimulation 5.00 0.84 and 4.85 0.94 were due to ovarian hyper stimulation in these animals. The results indicated that super-ov treatments induce superovulatory response in West African dwarf goats.

Abstract: the fish order pleuronectiformes, composed of 14 families, has two suborders: psettodoidei (with one family) and pleuronectoidei (with thirteen families). the relationships among families of pleuronectoidei and among the genera of their families have extensively been debated and a consensus has not yet been reached. in the present study, partial sequences of the 12s and 16s mitochondrial rrna genes were obtained from 19 species belonging to the families achiridae, bothidae, cynoglossidae, paralichthyidae, pleuronectidae, scophthalmidae, and soleidae. additional sequences of 42 pleuronectiform species were obtained from genbank. phylogenetic analyses were conducted by the methods of maximum-parsimony, maximum-likelihood and bayesian inference. our results corroborate the monophyletic status of all families, excluding paralichthyidae. in the family achiridae, the genus catathyridium (freshwater) was the sister group of trinectes (saltwater), and hypoclinemus (freshwater) was the sister group of achirus (saltwater). assuming that the putative ancestor of achirids lived in saltwater, it is suggested that the freshwater habitats in south america were colonized independently by different achirid lineages.

Abstract: we examined the genetic structure and the effects of a bottleneck in populations of the water rat nectomys squamipes, a primary host of schistosoma mansoni. eight microsatellite loci were studied in 7 populations from the sumidouro region of the brazilian state of rio de janeiro. our data, covering a four-year period during which a bottleneck occurred, revealed substantial variation (6-31 alleles per locus) and high levels of both observed (0.718-0.789) and expected (0.748-0.832) heterozygosity. most populations were in hardy-weinberg equilibrium without linkage disequilibrium between loci. overall average genetic differentiation between populations (estimated with the fst (q) and rst (r) analogues was 0.037 for q and 0.060 for r. there was significant allelic and genotypic differentiation between populations, especially in pairwise comparisons that included the most geographically isolated population. direct migration estimates showed a low rate of migration, indicating that infected n. squamipes populations had a limited ability to spread s. mansoni. when the pre- and post-bottleneck populations were compared there was no detectable reduction in heterozygosity or allele number, although a significant excess of heterozygosity was detected in the post-bottleneck population.

Pakistan Journal of Nutrition , 2007,
Abstract: The effect of boiling, roasting and autoclaving on the levels of some antinutrient factors present in the seeds of vegetable cowpea (sesquipedalis) were studied. The reduction of trypsin inhibitor was found to be highest (100%) with autoclaving at 60 min. Boiling was more effective in reducing phytic acid (68.34%) and haemagglutinin (75.98%) respectively at 60 min than the other processing treatments at the same time. The hydrogen cyanide was markedly reduced up to 81.25% at 15 min by autoclaving method while boiling at 60min resulted in (81.25%) reduction. Tannin content was reduced by boiling and roasting up to 75.00% at 60 min and 75.00% at 120 min respectively. Boiling and autoclaving at 60 min significantly reduced stachyose (60.52% - 84.21%) and raffinose (67.97 - 83.66%).
