Effect of organic manures on growth and yield attributes of Soybean (Glycine max L.) under Subabul (Leucaena leucocephala) based Agroforestry system

A field trail was carried out at the research farm of the School of Forestry and Environment, SHIATS, Allahabad. The experimental research site is situated at an altitude of 90 m above the sea level at 25.570 N latitude and 81.510 E longitudes. The experiment comprised seven treatments replicated thrice. The maximum germination % (96.67%), plant height (83.73cm), number of branches/ plant (11.93), fresh weight (185.28g), dry weight (45.73g), at 110 days after sowing (DAS), number of pods/plant (91.67), number of seeds/pod (3.93), pod length (6.93 cm),test weight (90.73g), seed yield (23.87q/ha), straw yield (40.73 q/ha) and harvest index (36.94%) recorded in treatment T5. The result showed that the applications of organic manure (50% Farmyard Manure + 50% Vermicompost) maximized the soybean growth and yield under subabul trees. Therefore, it may be concluded that 50% Farmyard Manure + 50% Vermicompost can be recommended for growing soybean under subabul based Agroforestry system for obtaining better growth and yield

Ethnomedicinal practices of Kol tribes in Similipal Biosphere Reserve, Orissa, India

Similipal Biosphere Reserve (SBR) in Mayurbhanj district of Orissa is the most luxuriant forest and rich in medicinal plant resources. The forest area is dominated by a number of tribes such as Kol, Santal, Bhumij, Mankidias and Khadias who depends on the forest for their food to medicine. The present paper reports on ethnomedicinal uses of 32 potential medicinal plants belong to 24 families of medicinal plants used for ailment of various diseases like leucorrhoea, spermatorrhea, piles, sore throat, rheumatism, elephantiasis etc. by Kol tribe living in some villages situated in and around Similipal Biosphere Reserve.The botanical name, family name, vernacular name, parts used, method of preparation, usage, administration of the drugs are given

Allelopathic effect of Leucaena leucocephala on Pansy (Viola tricolor L.)

The present study on allelopahtic effect of L. leucocephala on pansy (V. tricolor L.) both laboratory and nursery conditions were undertaken. Leucaena which significantly reduced the seed germination in all treatments at 2% (43%), 3% (42%) and 4% (40%) over Control (Distilled water), except in treatment at 1% (55%) wheregermination was found to be maximum over Control (Distilled water), this result shows the stimulatory effect on germination at 1% concentration of leaf leachate under laboratory condition. Leucaena soil in combination with Field soil showed stimulatory effect on the growth parameters in Pansy. Highest germination percentage (82%), fresh shoot weight (2.82g), fresh root weight (0.22g), dry shoot weight (0.50g), dry root weight (0.05g), vigor index (99.36) were recorded in treatment amended with soil 50% Leucaena soil and 50% Field soil and inhibitory effect was seen in pansy when amended into with 100% Leucaena soil under nursery condition. From this study it appears that Leucaena produces allelopahtic substrates, increase in concentration exhibit adverse effect on germination and growth parameters. Hence it is suggested that pansy could be affected economically but this tree can very well adapt to diversified soil condition

Structure-function mapping of a heptameric module in the nuclear pore complex.

The nuclear pore complex (NPC) is a multiprotein assembly that serves as the sole mediator of nucleocytoplasmic exchange in eukaryotic cells. In this paper, we use an integrative approach to determine the structure of an essential component of the yeast NPC, the ~600-kD heptameric Nup84 complex, to a precision of ~1.5 nm. The configuration of the subunit structures was determined by satisfaction of spatial restraints derived from a diverse set of negative-stain electron microscopy and protein domain-mapping data. Phenotypic data were mapped onto the complex, allowing us to identify regions that stabilize the NPC's interaction with the nuclear envelope membrane and connect the complex to the rest of the NPC. Our data allow us to suggest how the Nup84 complex is assembled into the NPC and propose a scenario for the evolution of the Nup84 complex through a series of gene duplication and loss events. This work demonstrates that integrative approaches based on low-resolution data of sufficient quality can generate functionally informative structures at intermediate resolution

Martian M2 peak behaviour in the dayside near-terminator ionosphere during ICMEs

The interplanetary coronal mass ejections (ICMEs) can pose significant impacts on the Martian ionosphere, resulting in plasma depletion, variability, and escape to space. However, the connections between the ICMEs and the associated responses of the dayside near-terminator Martian ionospheric M2 peak are not well understood. The present study primarily investigates the behaviour of the ionospheric peak density (Nm) and height (hm) during the passage of ICMEs using observations from the Radio Occultation Science Experiment (ROSE) aboard MAVEN spacecraft. We have selected 8 such ICMEs (during 2017-2022) at Mars from the existing catalogs and studied the ROSE electron density profiles during quiet and disturbed time (ICMEs) for identical solar zenith angle range. We observed the elevation of the M2 peak (hm ~4-16 km) during disturbed time (ICMEs) with a decrease in Nm (0.41-2.8 * 10^10 m-3) in comparison to the quiet time. The present study, for the first time, addressed the influence of ICMEs on the M2 peak parameters (Nm and hm). We have proposed that the development of large vertical pressure gradient and electron temperature enhancement are plausible causes for ionospheric variability. Therefore, the present study provides new insights to understand the peak plasma behaviour in the dayside near-terminator ionosphere during ICMEs

Some New Graceful Generalized Classes of Diameter Six Trees

Here we denote a {\it diameter six tree} by $(c; a_{1}, a_{2}, \ldots, a_{m}; b_{1}, b_{2}, \ldots, b_{n}; c_{1}, c_{2}, \ldots, c_{r})$, where $c$ is the center of the tree; $a_{i}, i = 1, 2, \ldots, m$, $b_{j}, j = 1, 2, \ldots, n$, and $c_{k}, k = 1, 2, \ldots, r$ are the vertices of the tree adjacent to $c$; each $a_{i}$ is the center of a diameter four tree, each $b_{j}$ is the center of a star, and each $c_{k}$ is a pendant vertex. Here we give graceful labelings to some new classes of diameter six trees $(c; a_{1}, a_{2}, \ldots, a_{m}; b_{1}, b_{2}, \ldots, b_{n}; c_{1}, c_{2}, \ldots, c_{r})$ in which a diameter four tree may contain any combination of branches with the total number of branches odd though with some conditions on the number of odd, even, and pendant branches. Here by a branch we mean a star, i.e. we call a star an odd branch if its center has an odd degree, an even branch if its center has an even degree, and a pendant branch if it is a pendant vertex
