An exploration was undertaken to identify better genotypes of date palm (Phoenix dactylifera) based on their fruit quality and yield-attributing characteristics. A total of 14 fruit samples were collected and data were analysed for fruit characters. Among the different genotypes MDR2 was identified and marked superior with respect to fruiting characteristics like fruit weight (29.86 g), fruit length (53.12 mm) and quality characteristics (TSS 35.17 ºB). In India, the coastal strip of the Kutch region contains the only remaining natural date palm groves, which should be utilised and maintained to be used in future genetic improvement programmes
Exploring the scenario of natural farming and food system in the North Eastern Hill Region of India: an introspective study
No full textThe agricultural practices in India's North Eastern hill region (NEHR) align with the philosophy of natural farming, which emphasizes working in harmony with natural cycles and processes of the natural world. Farmers in the region follow the traditional agriculture practices based on indigenous technical knowledge (ITK), these practices align with the attributes of natural farming such as; no-tillage, intercropping, mulching, crop rotation, no use of agrochemicals, functional biodiversity, crop diversity etc. evolved through experience and experiments by ancestors. As the indigenous communities habituated in the region have historically relied on natural resources, their food systems have been centred around forest-based resources, which include a wide variety of wild species. Therefore, this study endeavors to provide a comprehensive overview of the scenario of natural farming and food systems in NEHR. Further, it suggests assessing natural farming in the context of NEHR while taking food systems into consideration, along with the documentation of both cultivated and collected wild foods of significance

No full textThe present study was conducted to understand the butterfly diversity in the Sangla Valley of Kinnaur District of Himachal Pradesh, India from April 2015 to March 2018. A total of 40 species of butterflies belonging to 33 genera and five families were recorded from the present study. From the observed butterflies, the family Nymphalidae was the most dominant among the five families with 20 species, followed by Lycaenidae comprising 10 species, Pieridae with 07 species, Papilionidae with 02 species and Hesperiidae with 01species. The butterfly fauna of Sangla Valley has been documented for the first time. The diversity of butterflies is near lower altitudes as compared to alpine regions and Bhoj Patra forests in Cchitkul. Maximum diversity of butterflies exists in open spaces on wild vegetation. One species of Snow Apollo i.e. Parnassius hardwckii has been recorded for the first time from Sangla Valley landscape. The present study added valuable information on the diversity of butterfly fauna and will contribute in developing effective conservation measures in the Kinnaur district of Himachal Pradesh
Comparative analysis of various soils concerning chemical parameters in command (canal irrigated) and uncommand (well irrigated and rainfed) areas of Raisinghnagar, District Sriganganagar (Rajasthan)
No full textSoil is a vital source for the cultivation of all types of crops. The crop’s cultivation depends on the soil's physical and chemical properties. The optimum plant growth and crop yield depend not only on the total amount of nutrients present in the soil at a particular time but also on their availability which in turn is controlled by the physical and chemical properties of soil. So, in the present study, a comparative analysis was undertaken between various soil parameters (chemical properties of soil) of different vicinity like Command (canal irrigated) and Uncommand (well irrigated and rainfed) agriculture fields of various villages in Sriganganagar District, Rajasthan. The cumulative analysis of soil chemical parameters regarding the Command (canal irrigated) area and Uncommand (well irrigated and rainfed) area were undertaken during the study period
Imidacloprid residues in cotton guttation fluid, pollen and soil when applied as seed dressings
No full textGuttation fluid and pollen are possible pathways where pollinators may be exposed to systemic insecticides. During the investigation, Gossypium hirsutum v. H 1098i seeds were coated with Gaucho (Imidacloprid 600 FS at 2.4 g a.i. kg-1seeds) and planted in the field. Guttation fluid, pollen, and soil samples were collected during the season and the samples were analysed by HPLC (High-Performance Liquid Chromatography). The guttation fluid and pollen were collected at three times after 50 per cent flowering. Soil samples were collected before sowing and at harvest. Method validation was achieved by performing a recovery experiment at two fortification levels of 0.05 and 0.10 mg kg-1. The average recoveries obtained from guttation fluid, pollen and soil samples were above 85 per cent. The residues of imidacloprid in guttation fluid, pollen and soil in treated and untreated seed were below detectable levels
Microbiological resources- an alternate approach for sustainable management of fall armyworm (Spodoptera frugiperda)
No full textFall Army Worm (Spodoptera frugiperda), with the traits of devastating, voracious, polyphagous nature had recently imposed a global threat. Possessing these traits, this pest constituted a threat to global food security by ambushing more than several host plant species. To tackle this pest, insecticide management approaches was used initially. Later, with a better comprehension of the dynamic biology of the pest, such as their long migration capability, their ability to develop resistance against insecticide and the adverse effects of pesticides on human and the environment, an alternative strategy which is environmentally safe i.e., biological control approaches that is effective and low-risk is laid emphasis. A rich diversity of microbial populations which have the ability to infect the pest to a certain degree in nature remains untapped, and if so, identification of high virulence and productive strains within the population is lacking hitherto. This review focused on the information regarding the scenario of the occurring pest and its damaging nature to the host plants and microbial agents with their surplus potentialities along with the mode of interactions with the insect pest and self-perpetuating nature and their boon of disarming nature. The details of each microbe viz., fungi, bacteria and viruses that possess the traits of controlling the pest naturally are briefed with an insight into molecular information, present findings, constraint and future prospects
