Abstract

Devil’s cotton is an evergreen plant of medicinal importance which is distributed in tropical Asia, South and eastern Africa and Australia. In north-east India, this plant species is naturally distributed in Assam, Arunachal Pradesh, Meghalaya and Tripura. The present study was done on its distributional variation related with edaphic factors, abiotic as well as biotic factors associated with the target plant species in Assam, India where this plant species is declared threatened. A variation in edapholgical factors affects the morphological and anatomical characteristics of this plant species. The Pearson’s Correlation Coefficient matrix was calculated for all edaphic, abiotic as well as biotic factors. A negative correlation was observed in site elevation with most of the factors with exception in soil temperature and available soil organic carbon where the correlation was positive (0.01, 0.07). But high negative correlation values were observed in case of soil electrical conductivity (-0.75) and plant height (-0.44) indicating their inverse relation with the site elevation. The high positive correlated factor (0.94) was found in relative atmospheric humidity (%) with soil moisture content (%). The available soil organic carbon (%) was observed to influence plant height as the observed correlation was positive (0.87). The plant height was also positively influenced by the edaphic factors with the exception of soil temperature which was again found negative correlated (-0.75) with soil pH. This study also further reflects the variations in foliar, floral and anatomical characteristics due to edaphological factors.

Abstract

Present experiment was undertaken to study the impact of different organic manures on growth and yield of radish cv. Pusa Chetki. For this, a field experiment was carried out in Randomized Block Design with three replications. The experiment was conducted at the Horticulture Research Block of Shri Guru Ram Rai School of Agricultural Sciences during 2017-18. The experimental site is situated at 29o58’ N latitude and 77o34′ E longitude at an elevation of 640 m above mean sea level. For the experiment, ten treatment combinations are taken viz. T1- Control, T2- FYM 100 %, T3-Vermicompost 100 %, T4- Poultry manure 100 %, T5-FYM 75%+ Vermicompost 25%, T6- FYM 50%+ Poultry manure, T7- FYM 75%+ Poultry manure 25%, T8- FYM 50% + Poultry manure 50%, T9- Vermicompost 75% + Poultry manure 25% and T10- Vermicompost 50%+ Poultry manure 50%. Results shows that among the various sources of organic nutrients applied, treatment T10- Vermicompost 50%+ Poultry manure 50% perform better than all other treatments in terms of vegetative growth as well as yield parameters of radish. It was followed by treatment T6 - FYM 50%+ Poultry manure 50%.

Abstract

The present investigation was carried out with the aim to examining the socio-economic characteristics of farmers, types and uses of home gardens trees, soil status of home gardens and how trees help in biodiversity conservation in Rudraprayag (Malkhi and Khumera villages) and Uttarkashi district (Kurura and Panchan gaun villages) in Uttarakhand. The study was based on by using semi structure interview, field observation and simple preference scoring method in selected site. Three stage sampling technique was employed for constructing sampling plan of the study. The first stage of sampling plan was the selection of blocks from the selected districts, followed by selection of villages (second stage) and selection of respondents (third stage) from the selected villages. The study indicated that majority of the respondents were middle aged, belonged to general category, had education up to primary level, had nuclear family with small family size, pucca type house, small land holding pattern, maximum families served in government departments for income generation, lack of economic resources and maximum family engaged in bee keeping and horse rearing.

Abstract

Little data is available in the scientific literature on postharvest changes taking place in apple (MalusdomesticaBorkh) fruits, an increasingly popular fruit in the Uttarakhand Himalaya region. In this study the postharvest physico-chemical and mechanical properties, namely, fruit color, weight loss, pulp firmness, total soluble solids, pH and titratable acidity were determined during the postharvest storage period under ambient conditions of Malus domestica Borkha fruits. It was observed that weight loss, total soluble solids (TSS) and pH of the Apple fruits increased with time whilst pulp firmness and the color index of the fruits decreased. T1Turmeric powder(Curcurmalonga) (15%), T2Turmeric powder (Curcurma longa)(25%), T3 Drake (Meliaazedarach)(15%), T4 Drake (Meliaazedarach) (25%), T5 Mint(Menthaarvensis) (15%), T6 Mint(Menthaarvensis) (25%), T7 Water washes (control).

Keywords: MalusdomesticaBorkh, postharvest physico-chemical changes, antioxidant, flavonoid and phenolic content Abbreviations: AA-ascorbic acid TA-titratable acidity; TSS-total soluble solids.
