A hand operated maize dehusker-sheller to be operated by farm women was designed and developed to dehusk and shell the maize cobs using ergonomics (anthropometric, strength and physiological workload). Axial-flow maize dehusker-sheller with 540 mm cylinder length and 380 mm diameter required 3.03 N-m torque on cylinder shaft while operating at 5.6 m s-1 peripheral speed and 100 kg h-1 feed rate by feeding cob one by one. This torque was 30% of isometric torque obtained at front position of handle (greatest distance) with lowest crank length. The heart rate of subject while operating the maize dehusker-sheller at 54 rpm (5.6 m s-1) was 142 beats min-1. The output of 60 kg h-1 was obtained at the feed rate of 80 kg h-1. Two subjects can operate the machine for an hour with a rest pause of 15 min by swapping the operation. © 2011 Elsevier Ltd and The Ergonomics Society.

Cultivator, one of the agriculture farm tool, extensively suffers from the wear problem. In this paper, we report nanostructured chromium nitrite (CrN) coating for the cultivator shovels to mitigate wear problem. The (CrN) coating was developed using DC magnetron sputtering technique at 200 °C. The structural, morphological, hydrophobic and wear properties were investigated using X-ray diffractometer, scanning electron microscope, contact angle goniometer and custom designed soil bin assembly. The XRD reveals that the deposited coating was polycrystalline in nature with cubic structure. Also, The deposited coating was found to be anti wear resistant as well as hydrophobic in nature. The gravimetric wear for the coating developed at 200 °C coated was found out to be 8.15 gm and for non coated it was 14.48 gm tested for 100 hrs. The roughness of the coating plays an important role in determining the hydrophobicity of the coated film. Roughness and contact angle measured for 200 °C coated shovel was found out to be 11.17 nm and 105 ° respectively. © 2016 Author(s).

Skirt (a rectangular of material tied around the hip) is known to have been worn by men and women of Stone Age and before, but the skirts have seen a number of variations since then. There have been changes in their style, form, purpose and design. It is surprising that the "skirts" which form part of the wardrobe of a young girl today, and which is considered a dress of western origin, is in fact, closest to the very first clothing ever to be worn. The word skirt is of Scandinavian origin, coming from skyrta, which originally meant shirt.

Electrophoretic pattern of serum protein and dialysed serum protein profiles were studied from apparently healthy camels on 10% and 15% SDS-PAGE in addition to total protein and immunoglobulin content. The electrophoretic pattern of camel serum protein revealed 7 prominent bands of molecular weights ranging from 28.21 kDa to 123.07 kDa on 10% SDS-PAGE and dialysed serum protein revealed 4 prominent bands of molecular weights ranging from 24.30 kDa to 110.87 kDa. The electrophoretic pattern of camel serum protein on 15% SDS PAGE revealed 8 prominent bands of molecular weights ranging from 0.005 to 121.04 kDa along with 5 bands of dialysed serum protein. There are about 7 lower molecular weight bands which may be of prealbumin and other lower molecular weight proteins. The lower molecular weight bands may be of pre albumin. The band with higher molecular weight may be of different globulin fractions including immunoglobulins. Total protein and immunoglobulin content were low in present study possibly due to very hot temperature and limited grazing facility during summer.

Speckle noise contaminates image content and thus detracts from image interpretation. Speckle noise is the grainy salt-and-pepper pattern present in radar imagery caused by the interaction of out-of-phase waves with a target. Speckle noise reduction is usually employed prior to further image analysis. The primary goal of speckle filtering is to reduce speckle noise without sacrificing information content. The ideal speckle filter should adaptively smooth speckle noise, retain edges and features, and also preserve subtle but distinguishable details, such as thin linear features and point targets. Various speckle filters have been devised due to their different purposes and different capacities. In the present paper we are analyzing median, Lee and Wiener2 filters for the sampled SAR images from ENVISAT, RADARSAT2, US Library Congress and comparing their performances statistically by analyzing quality parameters like data mean, standard deviation, kurtosis and skewness. The paper is concluded with visual quality comparison of the input images and de-speckled images. © 2011 IEEE.

Field experiment was conducted for two consecutive rabi season of the years 2004-05 and 2005- 06, to find out the individual effect of varieties (Rmt-1 and Rmt-303), four fertility levels (0, 10 kg nitrogen + 20 kg phosphorous ha -1, 20 kg nitrogen + 40 kg phosphorous ha-1 and 30 kg nitrogen + 60 kg phosphorous ha-1) and three growth regulators (water spray, ethephon 100 ppm and nepthalic acetic acid (NAA) 20 ppm) were studied on yield, quality and economics of fenugreek. Cultivar Rmt-303 gave higher seed yield, protein content and net return as compared to cultivar Rmt-1. Application of 30 kg nitrogen + 60 kg phosphorous ha-1 gave significantly higher yield and protein content which was 30.94 and 19.98% more compared to control and this treatment was at par with 20 kg nitrogen + 40 kg phosphorous ha-1. Similar trend was followed for net return and B:C ratio. Application of NAA growth regulator (20 ppm) gave significantly higher yield, net return and B : C ratio compared to control and was superior over ethephon (100 ppm).

A field experiment was conducted during rabi 2011 and kharif of 2012 to estimate the magnitude of heterosis and heterobeltiosis for fruit yield and its attributing traits in brinjal. Ten indigenous parental lines of brinjal were selected and crossed in a half diallel-fashion and the resultant 45 F1 hybrids (excluding reciprocals) along with their parents were evaluated for yield and its component traits in a randomized block design (RBD) with three replications. The observations were recorded on five randomly selected plants per replication for each genotype on eight important characters, viz. days to first flowering, days to 75% flowering, days to first fruit harvest, number of fruit clusters/plant, fruit width (cm), number of fruits/plant, average fruit weight (g) and average fruit yield/plant (kg). Relative heterosis and heterobeltiosis provides an idea about the nature of gene actions involved in the genetic control of the concerned trait. Relative heterosis besides epistatic effects also indicate the presence of dominance effects (intra allelic interaction), while heterosis is indicative of over dominance. Analysis of variance and result reveals highly significant difference for almost all the characters. The heterosis and heterobeltiosis ranged from 23.33 to 197. 80% and from 21.06 to 166.03 %, respectively. The results of present investigation also revealed that the crosses P7 x P8 (PPC x Udaipur local) and P8 x P10 (Udaipur local and Pusa Bhairav) exhibited high degree of heterosis and heterobeltiosis for fruit yield and other yield attributing traits, viz. fruit weight, fruit width and number of fruits/cluster indicating the additive or synergistic effect of the component characters on fruit yield. © 2016, Indian Council of Agricultural Research.

Sorghum shoot fly (Atherigona soccata) is a serious pest that destabilizes the performance of sorghum cultivars and ultimately reduces sorghum production in many parts of the world. Identifying sorghum genotypes with stable resistance to shoot fly is important as it helps to reduce the cost of cultivation and stabilizes yields. In the present study, our objective was to identify stable shoot fly resistant genotypes among 385 recombinant inbred lines (RILs) of a cross between a susceptible parent and a resistant parent. We evaluated this set of RILs in eight environments over three years (2006-2008) for shoot fly resistance and component traits. Non-significant genotype-environment (G × E) linear component and significant pooled deviation for deadheart percentage indicated that the performance of genotypes was unpredictable over the environments. However, five lines had deadheart percentages much less than the population mean with regression coefficient (bi) values close to unity, and non-significant deviation from regression, indicating that they have stable shoot fly resistance and are well adapted to all the environments. Additive main effect and multiplicative interaction (AMMI) analysis partitioned main effects into genotype, environment and G × E interacts with all the components showing highly significant effects (p < 0.001). Environment had the greatest effect (69.2%) followed by G × E interactions (24.6%) and genotype (6.2%). Low heritability and high environmental influence for deadheart percentage suggested that shoot fly resistance is a highly complex character, emphasizing the need for marker assisted selection. We observed transgressive variation in the RIL population for all the traits indicating the contribution of alleles for resistance from both resistant and susceptible parents. Since the alleles for shoot fly resistance are contributed by both resistant and susceptible parents, efforts should be made to capture favourable alleles from resistant and susceptible genotypes. © 2011 Elsevier Ltd.

Shoot fly is one of the most important pests affecting the sorghum production. The identification of quantitative trait loci (QTL) affecting shoot fly resistance enables to understand the underlying genetic mechanisms and genetic basis of complex interactions among the component traits. The aim of the present study was to detect QTL for shoot fly resistance and the associated traits using a population of 210 RILs of the cross 27B (susceptible) × IS2122 (resistant). RIL population was phenotyped in eight environments for shoot fly resistance (deadheart percentage), and in three environments for the component traits, such as glossiness, seedling vigor and trichome density. Linkage map was constructed with 149 marker loci comprising 127 genomic-microsatellite, 21 genic-microsatellite and one morphological marker. QTL analysis was performed by using MQM approach. 25 QTL (five each for leaf glossiness and seedling vigor, 10 for deadhearts, two for adaxial trichome density and three for abaxial trichome density) were detected in individual and across environments. The LOD and R2 (%) values of QTL ranged from 2.44 to 24.1 and 4.3 to 44.1%, respectively. For most of the QTLs, the resistant parent, IS2122 contributed alleles for resistance; while at two QTL regions, the susceptible parent 27B also contributed for resistance traits. Three genomic regions affected multiple traits, suggesting the phenomenon of pleiotrophy or tight linkage. Stable QTL were identified for the traits across different environments, and genetic backgrounds by comparing the QTL in the study with previously reported QTL in sorghum. For majority of the QTLs, possible candidate genes were identified. The QTLs identified will enable marker assisted breeding for shoot fly resistance in sorghum. © 2011 Springer-Verlag.

Rhizoctonia solani AG 4 is a soilborne necrotrophic fungal plant pathogen that causes economically important diseases on agronomic crops worldwide. This study used a proteomics approach to characterize both intracellular proteins and the secretome of R.solani AG 4 isolate Rs23A under several growth conditions, the secretome being highly important in pathogenesis. From over 500 total secretome and soluble intracellular protein spots from 2-D gels, 457 protein spots were analyzed and 318 proteins positively matched with fungal proteins of known function by comparison with available R.solani genome databases specific for anastomosis groups 1-IA, 1-IB, and 3. These proteins were categorized to possible cellular locations and functional groups and for some proteins their putative roles in plant cell wall degradation and virulence. The majority of the secreted proteins were grouped to extracellular regions and contain hydrolase activity.
