An assessment of soil fertility status of different villages from Palakkad district, Kerala carried out 2021-22. The prime objectives of this work were to study the physico-chemical properties of soil at different depths of various sites of Attappady block of Palakkad District, Kerala to determine the availability of macro and micro nutrient on soil of these soil samples and provide Soil Health Card for farmers of the Attappady block, Palakkad District, Kerala. For the assessment 9 sampling locations were selected. Soil samples were collected with depth of 0-15 cm, 15-30 cm and 30-45 cm respectively. The Soil colour (Dry Condition) of soil varied from Brown, Dark brown, Yellowish brown, Yellowish red, Dark greyish brown, very dark brown and Brownish yellow. Soil colour (Wet Condition) of the soil varied Brown, Dark brown, Yellowish red, very dark greyish brown, very dark brown and Brownish yellow colour. Soil textural classes were sandy loam. It clearly indicated that soil has good Water Holding Capacity (54.19 to 61.80 %) and good physical condition, Bulk Density (0.938Mg m-3 to 1.365Mg m-3). Particle Density (2.124 Mg m-3 to 2.866 Mg m-3). Pore Space (50.018 % to 64.321%). The pH of soil is acidic nature (5.517 to 6.687) and the Electrical Conductivity (0.121 to 0.229 dSm-1) was suitable for all crops. Organic carbon ranged from medium to high (0.902 to 1.182 %). These soils have low Nitrogen (127 kg ha-1 to 252 kg ha-1) in all villages. Phosphorus (18 kg ha-1 to 34 kg ha-1) content is high at eight locations and medium at one location. Potassium (131.8 kg ha-1 to 383.9 kg ha-1) is low in one location and high in two locations. Calcium (5.9 cmol (p+) kg-1 to 8.6cmol (p+) kg-1) and Magnesium (1.2 cmol (p+) kg-1 to 9.8 cmol (p+) kg-1) are very sufficient in this soil. Sulphur (17 Mg kg-1 to 30.5 Mg kg-1) is high in five locations. Zinc (0.79 Mg kg-1 to 0.81 Mg kg-1) content is sufficient in this soil. There is an including awareness of the need to pay greater attention in the role of macronutrients enhancement pin the soil for good soil health and proper nutrition of plant so as to attain optimum economic yield and soil is suitable for all major tropical and sub-tropical crops.
A field experiment was conducted during Rabi season (November 2021-February 2022) at Central Research Farm NAI. SHUATS, analysed under RBD having nine treatments and three replications having three level of Zinc 0%, 50%, 100% and three level of Iron 0%, 50%, 100%. The results reported the significant improvement in soil chemical properties (EC (dS m-1) Organic Carbon (%), Available Nitrogen (Kg ha-1). Available Phosphorus (kg ha-1), Available Potassium (Kg ha-1), Available Zinc (mg Kg-1), Available Iron (mg Kg-1). However, Bulk density (Mg m³), Particle density (Mg m³), pH showed Non-significant improvement. Chemical properties of the soil increased with application of levels of Zn and Fe, Available NPK, Zn and Fe where found in moderate range. The application of Zn and Fe significantly improved the soil Physico-chemical properties. Increase in level of Zn application decreased in available Fe and P in the soil and increase in level of Fe application increased in available P and decreased in available Zn in soil.
The research work was conducted during Kharif season 2020-2021 at the Naini Agricultural Institute Research Farm of the Department of Soil Science and Agricultural Chemistry in Prayagraj (U.P). The data was recorded on 27 plots using 9 treatments including control having 3 levels of Biochar and Poultry Manure respectively (0%, 50%, 100% /ha). This research trial data was recorded based on mean performances in T9 (B3 P3) @ 100% Biochar + 100% Poultry Manure was showed the highest yield (98.05 q/ha). The combination effect of both soil amendment (Biochar and poultry Manure) shown highest results in plant height (cm), number of leaves, number of pods per plant, pod length(cm), weight of pods per plant (cm). The results showed that mean performances of growth parameters of cowpea are shown highest in 75 DAS was found significant. It can be concluded that from this research it is possible to recommend the treatment (T9) combination of Biochar (5 t/ha) + Poultry Manure (2 t/ha). It shows effective response to soil fertility and increase in plant growth parameters and yield of cowpea.
An experiment was conducted during Kharif season (July 2021 â Nov. 2021) which revealed after application of different levels NPK and boron applied through foliar application increases growth, yield of maize whereas through basal application the soil physical and chemical properties found to be best, in which maximum physical properties such as bulk density particle density % pore space water holding capacity varies from depth 0-15 cm to 15-30 cm was 1.305 Mg m-3 to 1.310 Mg m-3, 2.546 Mg m-3 to 2.548 Mg m-3 at 15- 30 cm, 46.87 % at 0-15 cm and 44.50 % at, 39.62 % at 0-15 cm and 37.95 % at 15-30 cm, pH 6.90 at 0-15 cm and 6.92 at 15-30 cm, EC 0.278 dSm-1 at 0-15 cm and 0.281 dSm-1 at 15-30 cm, organic carbon 0.561 % at 0-15 cm and at 0.550 % at 15-30 cm, available nitrogen 332.45 kg ha-1 at 0-15 cm and 325.22 kg ha-1 at 15 -30 cm, available phosphorus 35.75 kg ha-1 at 0-15 cm and 32.30 kg ha-1 at 15 -30 cm, available potassium 221.46 kg ha-1 at 0 -15 cm and 219.54 kg ha-1 at 15-30 cm, available boron 0.85 mg kg-1 at 0-15 cm and 0.73 mg kg-1 at 15-30 cm with cost benefit ratio is 1: 1.83 best from T1 [@ 0% RDF + 0% Boron].
A field experiment was done at Naini Agricultural Institute in Research Farm, Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj. In the research trial, the experiment was laid in randomized block design with nine treatments and three replications. The okra was planted at a spacing of 30cmÃ15cm. Growth parameters were collected on plant height (cm), number of leaves per plant, number of fruits per plant, weight of the fruit (g), length of the fruit (cm) and yield of okra fruits (q/ha). The results revealed that the combination of different treatments showed a significant effect on growth and yield parameters with protein and chlorophyll content of okra. Hence, it was concluded that the combination of NPK and Biochar was found to be useful for okra crop in terms of growth and yield parameters under the prevailing conditions of the study area.
