Wnt proteins represents highly conserved family of signalling biomolecules regulating vital developmental processes including embryo axis patterning, regeneration potential, cell fate specificity and determination in animals. Existence of Wnt protein mediated signalling in plants is still unexplored. Homologs of proteins like glycogen-synthase-kinase-3, casein-kinase-1 and Adenomatous-polyposis coli which together act as a negative regulator of metazoan Wnt signalling, have been traced in plants. Interestingly, genome-wide survey of cotton could reveal the presence of Wnt protein and its receptor, Frizzled up in Gossypium arboreum. Moreover, publicly available annotated sequence data have unravelled the existence of certain other proteins like Dishevelled homologs of betacatenin in plants. These proteins orchestrate the initiation of Wnt signalling pathway in animals. Manifestation of homologs of such Wnt signalling factors in plants, indicates a possible mimicry of similar signalling pathways. We have attempted to hypothesize a novel signalling network involving Wnt protein and other associated proteins in plants, considering animal systems as a model.Keywords

Due to advent of computations facilities and emerging technologies in the field of water sector, the gap between research and its applications is rapidly increasing. Problems and challenges in the field of hydrology and water resources have been discussed. Requirement of hydrological design aids as well as Decision Support Systems; necessity of preparation of standards, manuals, guidelines; strengthening of training and capacity building; importance of web portals and outreach plans; drawing talented young professionals to research institutions; upgradation of infrastructure; significance of crowd sourcing and engaging citizen scientists; integration of research and practice and action points for using emerging technologies are brought out.Keywords

Traditionally, common salt (NaCl) is applied to control broadleaved weeds under shifting cultivation in Nagaland. The aim of the present study was to find out whether such practice is harmful to the soil. For this, an experiment was conducted on upland rice with 12 treatments, viz. control, weedy check and different doses of NaCl from 20 to 200 kg ha-1. Soil samples were collected at several phases of shifting cultivation and analysed for organic carbon, available N, P, K, pH, electrical conductivity (EC), cation exchange capacity, exchangeable sodium percentage and sodium adsorption ratio. Yield and yield attributing characters were measured and economics was computed. The results revealed that soil organic carbon (SOC) increased after harvest, but decreased after one year. In contrast, available N, P and K decreased during the crop growth and post harvest period. Weedy check followed by an application of 100 kg NaCl ha-1 realized the highest gross and net returns. It was observed that NaCl did not exert an undesirable influence on pH, SOC and available NPK; however, EC increased for a short time. The results were confirmed by the verification trial. The yield of rice was highest in 100 kg NaCl ha-1 treatment among the treated plots. Hence, this may be recommended to control weeds under shifting cultivation.Keywords

The middle Indo-Gangetic Plain (MIGP) of India covering eastern Uttar Pradesh and Bihar is endowed with rich and diverse natural resources (land, water and environment), but low productivity and income. Rice-based cropping systems have maximum coverage of net sown area (9.64 m ha) in the MIGP1. Wheat, mustard, potato, maize and pulses are the major crops grown in rotation with rice. Rice–wheat system is extensively practised by the farmers of the region. This system requires high inputs in terms of machinery, nutrients, water and agro-chemicals. Unlike the northwestern part of the IGP (Trans and Upper IGP), the rice–wheat system of the MIGPs are less mechanized/labour-intensive due to small and fragmented land holdings and resource-poor farmers2. The total factor productivity index of the crops was reported to decline from 1.4% in Trans IGP to 0.43% in the MIGP2. Thus, the technological innovations along with socio-economic and policy reforms are the major challenges to sustain increase in productivity of ricebased production systems in the MIGP. There is a need to develop technologies for sustainable intensification and diversification of the rice–wheat system, including tillage and crop establishment options.References

Farmers in the North West Himalayan region generally practise rainfed agriculture and have very limited scope for irrigation. Water scarcity is a major constraint for crop production in these areas. This problem exacerbates further during the Rabi season where vagaries of winter rain result in complete crop failure. This study was conducted in the Raipur Block of Dehradun district in the farmer’s field to study the impact of hydrogel on yield and productivity of wheat. Hydrogel is a hydrophilic polymer having high water holding capacity and can provide water to crops during moisture stress. Hydrogel was applied in the field in Rabi wheat with two broad treatments, i.e. with hydrogel (WH) and without hydrogel (WHO). Each treatment was replicated ten times, i.e. ten demonstrations were laid out in the field conditions. Hydrogel was applied at the rate of 5 kg ha–1 and observations related to various plant growth parameters and yield were recorded. The plant population in hydrogel plots increased by 22% compared to the non-hydrogel treated plots. The effective tillers, plant height, ear length and grains per ear significantly improved due to hydrogel application. The total yield as well as grain yield increased significantly after hydrogel amendment. The improved performance of wheat upon hydrogel application was evident in the field. This technology could be promising in terms of productivity improvement of rainfed crops and in combating the moisture stress in agriculture.Keywords

Oroxylum indicum is a widely used multipurpose tree with its medicinal importance recognized by Ayurveda for centuries, as almost all parts of this tree possess medicinal value. Extracts of root and stem bark have antimicrobial, antifungal, anti-inflammatory and anti-cancerous properties. The high demand for this medicinal plant has caused a gradual depletion of the species from its natural habitat. The present study has been carried out to assess the distribution and mapping for the selection of elite germplasms on the basis of principal active constituents in different forest divisions of Punjab, India. The analysis led to the selection of three samples having a higher percentage of oroxylin-A, baicalein and chrysin. The three screened-out germplasms are recommended for conservation and multiplication to produce quality planting stock.Keywords

Air pollution is one of the environmental concerns which is a threat to the health of our plants and animals. Little knowledge exists in the literature about its impact on trees and crops. The objective of the present study was to assess the impact of air pollutants on the biochemical parameters of 19 tree and crop species from five different locations in Patna, Bihar, India. Air pollution tolerance index value showed that Ficus religiosa, Zea mays, Carthamus tinctorius and Cajanus cajan were more tolerant compared to the other crops. Anticipated performance index value showed that trees like F. religiosa, Azadirachta indica and Mangifera indica and crops like C. cajan, Z. mays and Triticum aestivum were most suitable under air pollution conditionKeywords
