Delineation of Spatial Variability of Soil Fertility through Digital Soil Maps: A case study of Central Plain Zone of North-West India
Digital maps are powerful tools that allow for the visualization and analysis of this variability, providing valuable insights into the distribution of features across space. Sustainable farming practices begin with focusing on smaller areas with better soil than larger ones. No single concept can account for the wide range in soil conditions. The current investigation was carried out at a Krishi Vigyan Kendra(KVK), Kapurthala, an agriculture extension centre of Punjab Agricultural University, Ludhiana, where 15 ha of farmland was divided into four blocks in order to map the spatial variation in soil properties such as soil organic carbon, electrical conductivity (EC), pH, and available phosphorus (P), potassium (K), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu) (mg kg-1), and SOC stocks using geo-statistics. To account for spatial soil variance, digital soil mapping (DSM) was developed following the creation of the base maps using QGIS. Using a standardized technique and GPS instrument, a total of 69 soil samples were collected from different locations in blocks A, B, C, and D, at various soil depths (0-15 cm, 15-30 cm, and 30-60 cm). The surface soil pH in KVK was found to be close to neutral (7.06), while the electrical conductivity (EC) and soil organic carbon (SOC) ranged from 0.7 to 0.21 m mhos cm-1 and 1.95 to 3.98 g kg-1, respectively. For different crops, it was observed that a 25% higher dose of fertilizers than the recommended amount was necessary. In specific quantities, the average phosphorus content in blocks A, B, C, and D was 10.15 kg ha-1, 9.27 kg ha-1, 8.99 kg ha-1, and 9.35 kg ha-1, respectively. Similarly, the average potassium content in the same blocks was 112.4 kg ha-1, 103.3 kg ha-1, 102.5 kg ha-1, and 107.4 kg ha-1. These results indicate deficiencies in phosphorus and potassium levels and suggest the application of appropriate fertilizers to address the nutrient imbalances in the soil. The values for DTPA-Fe, Mn, and Cu in the surface soils of each of the four blocks (A, B, C, and D) were 20.12, 13.92, 6.88, and 4.86; 7.31, 6.08, 15.10, and 15.30; 1.23, 0.75, 0.54, and 0.64 mg kg-1. The DTPA-Zn content of the topsoil in Block A was 7.21 mg kg-1, but in Block C it was only 1.41 mg kg-1. No micronutrients were needed in any KVK block. Block A has the largest C stock (17.04 Mg ha-1) while block C had the lowest (13.22 Mg ha-1). The KVK as a whole had average bulk densities. Soil quality can be enhanced through the use of organic amendments such as green manuring, farm yard manuring, etc. These maps support land-use planning, precision agriculture, and monitoring soil health over time to make informed decisions for sustainable land management practices.
Impacts of water hyacinth planting media (Eichornia crassipes) on the growth of lettuce (Lactuca sativa), leaf mustard (Brassica intergrifolia) and tomato (Solanum lycopersicum) with hydroponic method
Water hyacinth (Eichornia crassipe) is a strongly invasive aquatic species that have great impacts on the economy, society, and environment. Water hyacinth treatment is an urgent and long-term issue. Organic composting from water hyacinth has been identified as one of the easiest and most eco-friendly methods for transferring nutrients to the plant’s growth cycle. Additionally, hydroponics is a method of growing plants according to new technology for high productivity and food safety. In this research, we combined the hydroponic growing method with the use of organic water hyacinth planting media for growing lettuce (Lactuca sativa), leaf mustard (Brassica intergrifolia) and tomato (Solanum lycopersicum). The results showed that water hyacinth planting media mixed with coir greatly influences on the growth and productivity of hydroponic lettuce, leaf mustard, and tomato. The mixture of water hyacinth and coir in a ratio of 50%:50% is the most suitable method for growing lettuce, and leaf mustard on a nutrient film technique system. Lettuce and leaf mustard growing on a water hyacinth planting media experienced an increase in root weight and length. The mixture of water hyacinth and coir in a ratio of 75%:25% is the most suitable for growing tomatoes (Solanum lycopersicum). Tomato growing on a water hyacinth planting media has an increased sprouting rate, a shortens flowering time, an increased flower number, and improves the rate of fruiting as well as enhances productivity. The nitrate content in all obtained samples satisfies WHO’s safety standards; furthermore, the lead, mercury, arsenic, and cadmium contents are not detected in the vegetable samples.
NANO-HERBAL FORMULATION AS FIXATIVE AND EMBALMING SOLUTION
Embalming carcasses is a vital step for taking proper dissection classes. Most commonly 4% formalin solution was used for embalming from the renascence period to till to the date. Formalin and its based solutions are toxic, carcinogenic, and hazardous. So the exposure to the toxic compound was higher in the dissection halls compared to histology laboratories. Therefore to reduce the risk several herbal combinations were used as alternatives to formalin. We prepared a Nano-herbal solution with the help of a sonicator using natural oils and extracts from easily available herbal plants. The preservation of the carcass was assessed by histological studies. This technique may give a new and innovative idea to conserve carcasses for teaching gross and microanatomy purposes.
Identification and detail description of phenological growth stages of wood apple (Feronia limonia L.) under rainfed conditions of India
An acquaintance about the phenology of cultivated crop is required for its proper management. Phenology reveals the timing of recurring biological events like bud break, flushing, flowering and fruiting. Therefore, a study was conducted to find out various phenological stages of wood apple under hot semi-arid condition during 2016 and 2017 at Central Horticultural Experiment Station (ICAR-CIAH), Vejalpur, Gujarat. Based on the extended BBCH-scale, three digit codes were used in this study to know the growth stages of the wood apple tree. In present study, seven principle growth stages were observed in terms of code like 0) bud, 1) leaf, 3) shoot development, 5) inflorescence emergence, 6) flowering, 7) fruit development, and 8) fruit maturity. The swellen axillary buds require 7-8 weeks for full shoot development and vegetative growth usually complete in 18-22 weeks. The peak flowering period was observed between mid March to mid April and lasts about 2-5 weeks. Wood apple fruit showed double sigmoid growth pattern and took about 20-22 weeks from fruit set to maturity. It has been observed that the days required 18-20 from bud swelling to complete anthesis for reproductive cycle. This study will be very useful to carryout various agro-cultural practices to enhance the production and productivity of wood apple under field condition based on the physiological events.
Study of heritability and genetic advance for the selection of improved genotype based on quantitative and quality characters in bread wheat (Triticum aestivum L.)
The aim of the present study is to develop new and improved wheat varieties with the help of heritability and genetic advance. In order to fulfill the aim of this study, a field experiment was conducted at C.S. Azad University of Agriculture and Technology, Kanpur. The high estimates of heritability were observed for days to maturity, plant height, number of productive tillers per plant, number of grains per spike, 1000-grain weight (g), grain yield per plant (g), harvest index (%), and protein content (%) in both F1 and F2 generations. In most of the characters, high heritability was accompanied with moderate genetic advance. Moderate value of heritability was recorded for biological yield per plant in both generations; days to 75% heading and number of spikelets per spike was in F2 generation, mostly accompanied with low genetic advance. The low heritability was observed for spike length in F2 generation which was also accompanied with low genetic advance in both generations.
