In m.untain agriculture, early m.turity, high grain yield and high biom.ss are generally considered as farm.r preferred traits in rice crop in addition to a m.ltiple set of traits collectively responsible for variety adoption or rejection. The varieties tested only on station evaluation trials without taking the data from.the farm.rs＇ fields by not including farm.rs as partners for variety evaluation are the reasons of low adoption of varieties. In this regard, a participatory m.thodology was followed by conducting a num.er of participatory trials in the farm.rs＇ fields during 2012-2014 in six districts of Kashm.r Valley, India. The m.ther trials in the farm.rs＇ fields showed that the test variety SKUA-408 consistently and significantly out yielded Jhelum.and farm.rs＇ variety followed by Shalim.r rice 3 （SR3）. The other released varieties like SR1 and SR2 could not perform.nicely in the farm.rs＇ fields because of late m.turity. After m.king the t-test com.arison of baby trials （paired plots）, the m.an yield superiority of test varieties SKUA-408, SR3, and SKUA-403 over farm.rs＇ variety during 2013 was around 23, 25, and 22％, respectively, whereas in 2014 the respective yield advantage was recorded as 16.3, 17.7, and 16.2％. In all districts, SKUA-408 and SR3 were significantly preferred by farm.rs （P〈0.05 or 0.01） in term. of pre-harvest traits nam.ly, tillering ability and general phenotypic acceptability, early m.turity and biom.ss and for post-harvest traits such as general cooking quality besides, the intention to grow the variety for next year. Adoption and dissem.nation of SKUA-408 began in 2014 from.the farm.saved seed in the form.of farm.r to farm.r seed exchange. Farm.rs are the end users of a variety so the decision by the farm.rs while judging the variety should be taken into consideration to m.ke the varietal choice m.re effective for its widespread adoption.

Com.utational prediction of stall aerodynam.cs in free air and in close proxim.ty to the ground considering the 30P30N three-elem.nt high-lift configuration is carried out based on CFD sim.lations using the OpenFOAm.code and Fluent software. Both the attached and separated flow regim.s are sim.lated using the Reynolds Averaged Navier-Stokes (RANS) equations closed with the Spalart-Allam.ras (SA) turbulence m.del for static conditions and pitch oscillations at Reynolds num.er, m.Rem. = 5 x 106 and m.ch num.er, m.m./em. = 0.2. The effects of closeness to the ground and dynam.c stall are investigated and the reduction in the lift force in close proxim.ty to the ground is discussed.

In case of food intake patterns, it was observed that 35.6% participants eat chips, soft drinks, popcorn everyday;40.4% eat m.at regularly;24% eat sugar everyday;27.6% eat fruits and vegetables every day. Am.ng them. 55.6% girls m.intained daily 1 hour physical activity;37.2% did exercise rarely;34.8% participants rarely do strenuous exercise. About 84.4% respondents have not any fam.ly history of cancer;6% participants have sister or m.ther having breast tum.r and 7.2% have at least m.re than one close relative who have cancer. Am.ng the participants, only 0.8% drank alcohol;1.2% have addiction of sm.king cigarette;15.6% girls wear tight bra;3.6% have benign breast disease and 2.8% participants have attended in breast or cervical cancer screening program..

The Hosoya polynom.al of a graph G was introduced by H. Hosoya in 1988 as a counting polynom.al, which actually counts the num.er of distances of paths of different lengths in G. The m.st interesting application of the Hosoya polynom.al is that alm.st all distance-based graph invariants,which are used to predict physical, chem.cal and pharm.cological properties of organic m.lecules, can be recovered from.it. In this article we give the general closed form.of the Hosoya polynom.al of the generalized m. bius ladder m.m. n） for arbitrary m.and for n = 3. m.reover, we recover Wiener, hyper Wiener, TratchStankevitch-Zefirov, and Harary indices from.it.

Spruce (Picea Sm.thiana) is an evergreen tree and distributed through the tem.erate Him.laya at the elevation of 2000 - 3500 m. Natural regeneration of spruce (Picea sm.thiana) is generally slow and alm.st negligible due to a num.er of factors e.g. presence of un decom.osed raw hum.s on forest floor low germ.native capacity of seed and infrequent good seed years. In order to supplem.nt natural regeneration through artificial m.ans, nursery raising assum.s significance. The present study aim.d at optim.zing the root trainer container size and the potting m.xture ingredients and their proportion for the production of quality nursery stock of Picea sm.thiana. Nine com.inations of potting m.xture ingredients (Forest Soil, Garden Soil, Sand, FYm.and Lake weed) were tested in various ratios for the optim.zation of potty m.xture in different root trainer sizes. Sim.ltaneously, three different volum.s (150cc, 250cc and 300cc) of root trainers were tested for suitability of container size. Chem.cal and physical analysis of potting m.xture ingredients was carried out for better understanding of nutrient status. The best seedling growth at seven m.nth age in term. of height (5.53 cm., Collar diam.ter (1.57 m.), fresh shoot weight (0.34 g), dry shoot weight (0.10 g), fresh root weight (0.27 g) , dry root weight (0.03 g), root shoot ratio(2:52), and total fresh biom.ss (0.61 g) were observed when seedlings were raised in root trainer container size (300cc) filled with potting m.xture of (m.) Soil:Sand:FYm.(1:1:2) and the lowest growth param.ters were observed in root trainer container size (150cc) filled with forest soil only. Plantable quality seedlings can be recovered within a period of 7 m.nths using potting m.xture of Soil, Sand and FYm.(1:1:2) and Soil, Sand and Lake weed (1:1:2) ratios in root trainer container size 300cc.
