The study was carried out to evaluate the global soil moisture product of Advanced Microwave Scanning Radiometer-2 (AMSR-2), Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR-E), Soil Moisture and Ocean Salinity (SMOS) and Tropical Rainfall Measuring Mission’s (TRMM) Microwave Imager (TMI) in central region of India for monsoon period of 2011 and 2013. The evaluation was done using 100, 75 in-situ soil moisture measurements of 2011, 2013 respectively. The in-situ measurements were spread across ~10,000 sq.km area which is roughly equal to 12 pixels of SMOS, AMSR-2 AMSR-E and TMI data. The result shows reasonable correlation of r2 = 0.506, 0.467 between SMOS and in-situ soil moisture for 2011, 2013 respectively. TMI exhibits good correlation of r2 = 0.55 in 2013 but failed to do the same in 2011. AMSR-2 soil moisture products shows moderate correlation r2 = 0.32 in 2011 but poorly correlated in 2013. © 2016 Indian Society of Remote Sensing

An experiment was conducted during 2005–06 and 2006–07 winter seasons to study the effect of drip irrigation regimes and fertility levels on physiological parameters, growth and yield of ashwagandha (Withania somnifera L. Dunal). The treatments consisted of three irrigation regimes, viz., I1: drip irrigation at 100 % pan evaporation (PE), I2: drip irrigation at 80 % PE and I3: drip irrigation at 60 % PE, combined with three fertility levels, i.e., F1: 100 %, F2: 75 % and F3: 50 % of recommended dose of NPK, control having surface irrigation and soil application of fertilizers. The cultivation of ashwagandha with application of drip irrigation at 80 % of pan evaporation along with application of 100 % recommended dose through fertigation resulted in significant improvement in growth, physiological parameters such as crop growth rate, relative growth rate, net assimilation rate, leaf area index, chlorophyll content, and root and seed yields. © 2014, Indian Society for Plant Physiology.

Submergence is an intensifying problem in major rice producing areas, when intolerant cultivars are submerged, they show a number of morpho-physiological changes such as elongation and chlorosis which is markedly developed after desubmergence probably due to oxidative damage. We studied the effects of submergence on survival, photosynthesis, nonstructural carbohydrate content, enzymatic activities, growth and yield of Sub1 and non-Sub1 cultivars. The interaction effect of nitrogen (N) and silica (Si) application was also examined for the submergence tolerance in rice. The photosynthetic rate, survival, growth of all the cultivars decreased during submergence but to a greater extent in IR64 and Swarna. After desubmergence, both the type of cultivars experienced oxidative damage, however, the oxidation of lipids was maintain at lower levels in Sub1 cultivars and anti-oxidants activities was increased more than intolerant cultivars. Application of basal Si was beneficial whereas, pre- and post-submergence Si spray was detrimental in relation to submergence tolerance. Basal Si resulted in significantly reduced elongation, lodging, leaf senescence, and chlorosis; when combined with post-flood N application either as broadcasting or spray, it led to significantly highest survival, photosynthesis, anti-oxidant activity and ultimately yields. Interaction of basal Si and post-flood N spray was the most promising method of nutrient application which not only resisted the damage during submergence but also enhanced the survival, growth after recovery in terms of number of green leaves emergence, leaf area and photosynthetic rate leading to significantly higher yield. The findings of the investigation propounds that a simple alteration in the time and method of nutrient application can significantly contribute to higher survival, crop establishment and yield in flash-flood prone areas. © 2016 Elsevier B.V.

Among the four cultivated cotton species, G. hirsutum (allotetraploid) presently holds a primary place in cultivation. Efforts to further improve this primary cotton face the constraints of its narrow genetic base due to repeated selective breeding and hence demands enrichment of diversity in the gene pool. G. arboreum (diploid species) is an invaluable genetic resource with great potential in this direction. Based on the dispersal and domestication in different directions from Indus valley, different races of G. arboreum have evolved, each having certain traits like drought and disease resistance, which the tetraploid cotton lack. Due to lack of systematic, race wise characterization of G. arboreum germplasm, it  has not been explored fully. During the present study, 100 polymorphic SSR loci were  used to genotype 95 accessions belonging to 6 races of G. arboreum producing 246 polymorphic alleles; mean number of effective alleles was 1.505. AMOVA showed 14 % of molecular variance among population groups, 34 % among individuals and remaining 52 % within individuals. UPGMA dendrogram, based on Nei’s genetic distance, distributed the six populations in two major clusters of 3 populations each; race ‘bengalense’ was found more close to ‘cernuum’ than the others. The clustering of 95 genotypes by UPGMA tree generation as well as PCoA analysis clustered ‘bengalense’ genotypes into one group along with some genotypes of ‘cernuum’, while rest of the genotypes made separate clusters. Outcomes of this research should be helpful in identifying the genotypes for their further utilization in hybridization program to obtain high level of germplasm diversity. © 2015, Prof. H.S.

The diploid cultivated cotton (Gossypium arboreum) is an invaluable genetic resource for the improvement of primary cotton. First step for this is a systematic race wise characterization using molecular markers. Present study attempted to characterize 95 genotypes with ISSR markers. The 100 selected markers produced a total of 397 bands, of which 368 were polymorphic. The PIC values ranged from 0.23 to 0.5 (average 0.40). Resolving power and marker index were calculated to know the efficiency of markers. The mean number of effective alleles was 1.409 and the mean value of shannon's information index was 0.368. AMOVA test showed that 17% of molecular variance were due to 6 population groups and rest due to variance in each group. The six populations were distributed in two major clusters by UPGMA while PCoA analysis could not differentiate population groups accurately. Outcomes of this research will help in identification of right genotypes for any given breeding program.

The need for achieving food security is felt significantly in the recent years due to enormous pressure from the ever-increasing population in India. Owing to the change in preferences in crop production techniques over a period of time, several new challenges draw attention to food security. This article discusses various challenges to food security in India. Critical analysis is made on challenges like crop diversification, issues related to bio-fuel and medicinal plant cultivation, climate change, mismatch between water demand and availability, recent status in production of highyielding crop varieties and agricultural crop pricing and insurance and new trends in globalization and urban encroachments.

We have studied the proteome of the model plant Arabidopsis thaliana infected with a necrotrophic fungal pathogen, Alternaria brassicicola. The Arabidopsis-A. brassicicola host-pathogen pair is being developed as a model genetic system for incompatible plant-fungal interactions, in which the spread of disease is limited by plant defense responses. After confirming that a defense response was induced at the transcriptional level, we identified proteins whose abundance on 2-DE gels increased or decreased in infected leaves. At least 11 protein spots showed reproducible differences in abundance, increasing or decreasing during the progress of the infection. The pathogenesis-related protein PR4, a glycosyl hydrolase, and the antifungal protein osmotin are strongly up-regulated. Two members of the Arabidopsis glutathione S-transferase (GST) family increased in abundance in infected leaves. The spots in which these GST proteins were identified contain additional members of the GST family. Representation of GST family members in several protein spots migrating at similar molecular weight suggests post-translational modifications. The signature of GST regulation may be specific for the type of plant-pathogen interaction. The proteomic view of the defense response to A. brassicicola can be compared with other types of plant-pathogen interactions, and to leaf senescence, identifying unique regulatory patterns. © 2009 Elsevier B.V.

There is yield gap due to inadequate and imbalance supply of fertilizers and lack of distinct fertilizer recommendation for plenty of varieties and hybrids of pearl millet (Pennisetum glaucum (L.) R. Br.). To bridge this gap, a field experiment was conducted during July to September of 2013-2014 to study the effect of potassium nutrition along with recommended dose of fertilizers on nutrient uptake and soil fertility. The experiment was laid out in randomized block design replicated four times with five treatments of different levels of potassium. Significantly highest root volume (19.40 cc) was figured out with RDF+45k being on par with RDF+30k (18.70 cc). Both these treatments found statistically similar. Other fertilizer treatments did not reached to the level of significance when compared with former treatments. The maximum total nitrogen, phosphorus and potassium uptake (58.22, 13.95 and 57.95 kg NPK/ha) was recorded with treatment RDF+45k being on par with RDF + 30k. © Copyright EM International.

The sustainability of organic cotton (Gossypium hirsutum L.) based production system vis-a -vis non-organic system under low input, semi-arid pedo-climatic conditions was evaluated during 2001 through 2005 on farmers' fields in Yavatmal district, Maharashtra. Mean yield of cotton, mungbean [Vigna radiata (L.) R. Wilczek], soybean (Glycine max L. Merr.) and chickpea (Cicer arietinum L.) were either similar or slightly higher under the organic system than the non-organic system. The organic system also had a higher diversity index (4.3) than the non-organic system (2.9). Organic cultivation practices did not improve fibre quality parameters. Samples from 4 soil pedons and 56 surface soils were analyzed in 2001 and again in 2005. Soils from non-organic pedons had a higher pH and ex-Na, whereas the organic carbon content was higher under organic system. During both the sampling periods, the mean organic carbon and available Zn were significantly higher in the organic system. AU the soils were calcareous but the proportion of organic to total carbon was higher in organic system and between sampling periods, this increased from 54.5 to 57.5%. Thus, adoption of organic production practices improved the biophysical sustainability of the low input systems prevailing in semi-arid pedo-climatic conditions of the region.
