Effect of organic inputs on nutrient status and quality of high density guava under organic management in north western plains of India
Organic farming in guava has opened a new vista for sustainable crop production under this covid pandemic situation where every human being is moving forward for healthy and chemical free fruit production. For keeping the safety rules for human health an experiment was conducted to study the impact of different organic manures solely or in combinations with biofertilizers on fruit quality and relative economics of high density guava during winter season in the experimental farm at Organic Farming Research Centre (OFRC), Chatha at Sher-e-Kashmir University of Agricultural Sciences & Technology, Jammu (J&K). The experiment was conducted on three years old guava trees with 13 treatments alone or in combinations with vermicompost and poultry manure and biofertilizers (Azotobacter and PSB) during the first week of July. The results of the experiment revealed that highest organic carbon (7.6 g kg-1), water holding capacity (52.10 %), soil microbial biomass(97.98 mg kg-1) and lowest bulk density (0.29 g cm-3) were recorded from the with the application of farmyard manure (25%) + vermicompost (50%) + poultry manure (25%) (T12) whereas, highest leaf N, P & K (1.73, 0.23 & 1.28 %) content were obtained with the treatment comprising of full dose of N through PM + Azotobacter + PSB (T9). The same treatment (T9) also recorded highest leaf chlorophyll content to the corresponding value of 9.96 mg g-1 tissue. The data also revealed that full dose of N through poultry manure + Azotobacter+ PSB (T9) recorded highest fruit TSS, pectin, vitamin C and total sugar. It was found that full dose of N through poultry manure+ Azotobacter+ PSB (T9) was considered as best treatment with the maximum profit of Rs. 6,52,888 and benefit cost ratio of 1: 5.26.
Evaluation of seed quality in artificial aged seeds (accelerated ageing techniques) of Chickpea during invigoration
The laboratory trial was conducted in the State Seed Testing Laboratory during rabi season 2018, to normalize the best treatment of plant development controller with preparing explicit to Chickpea (Pusa-362). Initially, Relative humidity (90% RH), distinctive temperature (350 and 400 C), Days (2,4 days) are utilized for seed aging after that utilized hormonal preparing viz; gibberellic acid (GA3) and salicylic acid (SA), to improve germination and seedling characters. Two plant growth regulators, GA3 and SA with control (untreated) were assessed by screening 12 hrs hour and 100 ppm fixation. In this trial utilized various conditions viz; T1-Temperature (350C), T2-Temperature (400C), H1 - Humidity (90% RH), D1-Duration (2 Days), D2-Duration (2 Days), P1-Gibberllic Acid, P2-Salicylic Acid, with various treatments viz; To - control (untreated), T1 - H1T1D1, T2 - H1T1D2, T3 - H1T2D1, T4 - H1T2D2, T5 - P1H1T1D1, T6 - P1H1T1D2, T7 - P1H1T2D1, T8 - P1H1T2D2, T9 - P2H1T1D1, T10 - P2H1T1D2, T11 - P2H1T2D1, T12 - P2H1T2D2. It was demonstrated that all the treatment indicated significant differences with the control and the most elevated germination percent, seedling length, seedling fresh weight, seedling dry weight, Vigour index were estimated for (GA3) T5 - P1H1T1D1. Pre-sowing treatment with PGRs effective on aged seeds, its straight forwardness and hormones could be utilized as a basic technique to identified with a helpless germination and seedling foundation and aides in continuing farming and financially low expense and monetary, non-poisonous, eco-friendly sources.
Agronomic responses and molecular breeding approaches towards elevated ozone in rice
Rice (Oryza sativa L.) is one of the most important staple food crop cultivated in South East Asia fulfilling the dietary needs of the people. This crop is being influenced by a variety of abiotic and biotic factors contributing to a change in its physiology, biochemistry as well as its genetics. Abiotic factors including oxides of nitrogen, carbon and an array of volatile organic compounds react with UV radiation leading to the generation of ozone in the troposphere. The ozone influence on rice has caused a lot of concern among the rice scientists and has necessitated the development of strategies to combat the problem. Molecular biology approaches including marker assisted selection involving QTLs linked to genes conferring tolerance to ozone stress have been identified due to the recent breakthroughs in rice genomics. Many medium-effect loci instead of single large-effect loci are supposed to govern the trait. The present review is an approach to provide information on the physiological, biochemical and molecular responses of rice towards elevated ozone tolerance and also reflect the available strategies to minimize the effect.
Genetic variability in different accessions of Asparagus racemosus under Jammu sub-tropics
Twenty accessions of Shatavar (Asparagus racemosus) were evaluated under subtropical conditions of Jammu region in a three replicate randomized block design to estimate growth performance, genetic variation, broad sense heritability and correlation between yield and yield components. The accessions IC471923 (3.98 tons ha-1), IC471922 (3.88 tons ha-1), IC471911(3.84 tons ha-1) and IC471909 (3.50 tons ha-1) had highest tuber dry weight (tons ha-1) and showed high performance for other characters. They proved to be the most promising accessions in sub tropics of Jammu region. High heritability combined with high genetic advance was marked for clump weight per plant (77.01%, 78.05%), number of tubers per plant (66.41%, 53.56 %), tubers fresh weight per plant (84.62%, 88.29%) and tubers dry weight per plant (85.47%, 86.70%). High positive correlation was found between clump weight and fresh weight of tubers per plant (0.989) followed by fresh weight of tubers per plant and dry weight of tubers per plant (0.985) and clump weight and dry weight of tubers per plant (0.976). From the present investigation, it is found that IC471923, IC471922, IC471911and IC471909 are elite in terms of greater dry tuber yield and clump weight per plant, number of tubers per plant, and fresh and dry weight per plant and can be used for selection in asparagus improvement programme.
Spatial Distribution of Soil Physico-Chemical properties of North Western Himalayan Region of Jammu and Kashmir, (India) Using Inverse Distance Weighted (IDW) Interpolation Technique in GIS Environment
Soil surveying and soil mapping is a significant operation, since it plays a significant role in the knowledge about soil properties. The selection of a spatial IDW interpolation technique will impact the quality of site-specific soil fertility maps. This study was carried out in order to thematically map out some soil physico chemical characteristics in the north western Himalayan region of Jammu and Kashmir, India. Some physical and chemical properties of the soil were determined to evaluate the current situation of the Khag micro-watershed of Kashmir valley, since no similar study had been conducted in the area to evaluate the soil status. Traditionally, soil property values are acquired either from thematic soil maps or from geostatistical approaches and IDW technique using exact laboratory measurements. Both data types convey considerable information: thematic soil maps through IDW interpolation technique provide comprehensive but vague information; while as laboratory analyses provide exact but scarce measurements. Ideally, they should be combined with the help of GIS. The use of the geographic information systems (GIS) and sampling broad analysis through the use of global positioning system (GPS) is found to be a very effectual tool. The objective of this investigation is to conduct a soil survey in a new developing area using a non-traditional technique. Geo-spatial technology was used in this study to present the laboratory results of the soil analysis; as such, this was accomplished through preparation of thematic maps for soil properties. In order to assess and investigate soil properties of study area, a total of fourty four (44) composite surface soil samples were taken and examined and analyzed for physicochemical properties. The surface soils of upper zone (higher altitude) soils were coarser due to removal of finer fractions. The pH of the soils were slightly acidic to neutral, electrical conductivity was within normal range. The soils were found medium to high in organic carbon, the surface soils varied in texture from loam, silty loam, sandy clay loam and silty clay loam to clay loam.
