The results revealed that sowing method greatly affected the number of fertile tillers, biological yield, grain yield and harvest index value whereas grain spikeG 1 and 1000-grain weight were non significant. Among the method pore method supersede broadcast method. Similarly seed rates also highly significantly affected the grain yield and yield components except 1000-grain weight. Seed rate of 175 kg haG 1 produced grain yield of 5325. 13 kg haG 1 and proved to be the most economical seed rate. Though the interaction of methods and seed rates on number of fertile tillers and biological yield were highly significant, all other parameters were non significantly affected.
Peripartum cardiomyopathy (PPCM) is a rare clinical entity during pregnancy. PPCM is a diagnosis of exclusion. These patients do not have prior history of heart disease, and there are no other known possible causes of heart failure. It is more common in African countries, may be related to the consumption of kanwa, in the postpartum period. The multiparity, African descent and pregnancy-induced hypertension are a few risk factors for PPCM. The exact etiology of PPCM is not known; possible theories range from myocarditis to the maladaptation to the changes of pregnancy. The clinical manifestation varies from shortness of breath to thromboembolic phenomenon. Echocardiography is essential for diagnosis as well as differential diagnosis of PPCM. These patients preferably are managed in tertiary healthcare facilities. Anticoagulation and antiarrhythmic medications are pillars for the management of PPCM patients. If required, mechanical devices should be used temporarily. PPCM patients may need heart transplant. The beneficial role of bromocriptine and immunosuppression is not clear in PPCM patients. Subsequent pregnancies should be avoided to prevent the PPCM occurrence.
An experiment was conducted on the impact of different levels of bulk densities combination on yield and yield components of wheat. Three bulk density levels 1.00-1.30 (A) g cm-3, 1.30-1.60 (B) g cm-3 and 1.60-1.90 (C) g cm-3 with three different depths (0-15, 16-30 and 31-45 cm) were used in the experiment using silt loam soil (Pedocals). The total treatments were 27 in the experiment with three replications. The experimental design was completely randomized design (CRD). The treatment means were checked at the confidence level of 95% of probability. The soil 0-45 cm deep was shifted from the field (no-till) to the net house and was act as control. The results showed that the number of tillers plant-1, number of leaves plant-1 and thousand grain yield were non-significantly affected by all the treatments while number of seed emerged, root length, dry root weight, plant height, grain yield , biological yield and harvest index were significantly influenced by various treatments. The highest number of seed germinated (8.00) was found in the treatment BBB (1.30-1.60 g cm-3 in 0-15 cm, 15-30 cm, 30-45 cm soil depth), BAB (1.30-1.60 g cm-3 in 0-15 cm, 1.00-1.30 g cm-3 in 15-30 cm and 1.30-1.60 g cm-3 in 30-45 cm soil depth) and BCB (1.30-1.60 g cm-3 in 0-15 cm, 1.60-1.90 g cm-3 in 15-30 cm and 1.30-1.60 g cm-3 in 30-45 cm) while the lowest number of seed emerged (3.6) was found in AAA (1.00-1.30 g cm-3 in 0-15 cm, 15-30 cm and 30-45 cm soil depth), ACA (1.00-1.30 g cm-3 in 0-15 cm, 1.60-1.90 g cm-3 in 15-30 cm and 1.00-1.30 g cm-3 in 30-45 cm soil depth) and CAC (1.60-1.90 g cm -3 in 0-15 cm, 1.00-1.30 g cm-3 in 15-30 cm and 1.60-1.90 g cm-3 in 30-45 cm soil depth). The highest root length (13.12 cm) was found in the treatment AAA while the lowest root length (10.05 cm) was found in CAC. The highest dry root weight (5.67g) was found in the treatment ABA while the lowest dry root weight (4.79g) was found in control treatment. The highest plant height (42.67 cm) was found in the treatment of BBA while the lowest plant height (29.67 cm) was found in control. The highest biological yield (12.1 metric ton ha-1) was found in the treatment ABA while the lowest biological yield (6.8 metric ton ha-1) was found in control. The highest grain yield (4.4 metric ton ha-1) was found by ABB while the lowest (2.7 metric ton ha-1) was found in the control. The highest harvest index (39.79%) was found in the control while the lowest harvest index (34.54%) was found in CCA. The experiment showed that increasing bulk density above 1.60 g cm-3 resulted in decreasing the yield and yield component of the winter wheat. The number of seed emerged, root length, dry root weight, plant height, grain yield, biological yield and harvest index of wheat were significantly affected by soil bulk density in various depths.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
