Integrated Nutrient Management (INM) and Varietal Impact on Toria (Brassica campestris L. var. toria) Growth, Yield, and Economics
No full textOilseeds, particularly rapeseed-mustard, play a vital role in India\u27s agricultural landscape, contributing significantly to the economy. Toria, a winter oilseed crop, is of particular importance, cultivated in both irrigated and rainfed conditions. Fertilizers, especially nitrogen (N), phosphorus (P), and sulfur (S), play a crucial role in enhancing toria yield. Integrated nutrient management (INM), which includes the use of farmyard manure (FYM), is a sustainable approach to maintain soil health and improve crop productivity. The study evaluates the impact of nutrient management practices on toria growth and yield. Additionally, it compares the performance of the newly released toria variety \u27Tapeswari\u27 with traditional varieties (\u27T9\u27 and \u27T36\u27). The results indicate that \u27Tapeswari\u27 fertilized with 100% RDF + 25% N through FYM outperforms traditional varieties in terms of growth, yield attributes, and overall yield. The study underscores the importance of effective varietal selection and nutrient management for enhancing rapeseed-mustard production, profitability, and soil fertility
Effects of Naphthalene Acetic Acid and Zinc Sulphate on Fruiting Behavior and Quality of Litchi (Litchi chinensis Sonn.) cv. Rose Scented
No full textThe current study evaluated the effect of NAA and zinc sulphate to maintain fruiting behaviour and qualitative attributes of fruit in litchi cv. Rose scented. This experiment was done in 2022 and 2023 at the Horticulture Garden, Department of Fruit Science, C.S. Azad University of Agriculture and Technology, Kanpur (U.P.). There were sixteen treatments including four levels of zinc sulphate (0, 0.2, 0.4 and 0.6 %), NAA (0, 25, 50 and 75 ppm) and their combinations imitated in Factorial- CRD. The foliar application of treatments was done on January 28 and March 16 of each year, prior to flowering and fruit setting at pea stage, respectively. This experiment showed that the treatment with NAA 50ppm and 0.4% zinc sulphate improved fruit set (63.40 and 62.73 %), fruit retention (30.76 and 31.36 %) and reduced fruit drop (69.23 and 68.63 %). The same treatment blend increased juice content of litchi fruit (63.63 and 64.22 %) and also improved nutritional qualities of fruit like total soluble solids (22.75 and 22.62 0Brix), total sugar (14.48 and 14.54 %), ascorbic acid (41.22 and 41.64 mg/ 100g of pulp), organoleptic test (85.36 and 86.82) and minimum titratable acidity (0.473 and 0.421 percent) in litchi fruits. The treatment combination of NAA 50ppm and 0.4% zinc sulphate was found to be the best in this experiment

No full textThe experiment was conducted to study the effect of different plant growth regulators on yield of cucumber cv. Malini under shade net conditions. The experiment was carried out with 10 treatments GA3 at 75 ppm, 150 ppm and 250 ppm, Ethrel at 100 ppm, 200 ppm and 300 ppm, Salicylic acid at 75 ppm, 150 ppm and 250 ppm and control (water spray) in 3 replications. The yield parameters like number of fruits per plant, fruit weight, fruit length etc. were significantly influenced by plant growth regulators. Among all yield parameters superior values for maximum days taken for final harvest (86.49 days), maximum fruit weight (248.00 g) were recorded in treatment GA3 at 250 ppm, treatment GA3 at 75 ppm was recorded with the highest values for number of fruits per vine (9.46) and fruit diameter (4.56cm) and GA3 at 150 ppm recorded with highest values for fruit length (21.33 cm) as compared to other treatments. Among all treatments, treatment with GA3@ 75 ppm showed positive effect in terms of gross returns and over all net returns
Effects of NPKS Granular and Briquette Fertilizers on Some Soil Chemical Properties and Yield Parameters of Maize (Zea mays L.)
No full textThe primary objective of this multilocational study was to investigate the impact of NPKS granule and briquette fertilizers, on selected soil chemical properties and yield of maize. The treatments were made up of different rates of NPKS granules and briquette fertilizers namely: T1 (Control), T2 (Granule NPK 10- 20-20 (200 kg ha-1) + Granule Urea 217.2 kg ha-1), T3 (Granule NPKS 10- 20-20-3 (600 kg ha-1) + Granule Urea 87 kg ha-1 GrU), T4 (Granule NPKS 10- 20-20-3 (400 kg ha-1) + Granule Urea 87 kg ha-1 GrU), T5 (Granule NPKS 10- 20-20-3 (400 kg ha-1) + No Urea), T6 (Briquette NPKS 10- 20-20-3 (3 briquettes/hill) + Briquette Urea (2 briquettes/hill) and T7 (Briquette NPKS 10- 20-20-3 (3 briquettes/hill) + Briquette Urea (1 briquette/hill), were deployed in a randomized complete block design with four replications. Some soil chemical properties were assessed; pH, available phosphorus (P), exchangeable potassium (K), calcium (Ca), magnesium (Mg), cation exchange capacity (CEC), total nitrogen (N), and organic matter content. Findings revealed stable pH levels, low available P, and suboptimal exchangeable K levels in the soil, indicating that the treatment did not have any significant impact on the chemical properties of the soil. The application of Granular NPKS 10- 20-20-3 (400 kg ha-1) + Granular Urea 87 kg ha-1 GrU) to maize produced significantly higher cob length and cob diameter compared with the control at only Atebubu. Total grain yield exhibited no significant differences (P ≥ 0.05) among treatments at Atebubu and Nsapor respectively. Significant differences occurred in the 100-seed with T3 and T4 producing higher weights at Nsapor and Atebubu respectively. Although the differences between treatments were not statistically significant, the result indicate a potential positive effect of T3 and T5 on grain yield (t/ha). The study highlights the influence of NPKS fertilizers in granule and briquette forms on soil chemical properties and maize yield, with the granules performing better than the briquette hence recommended

Seed Priming and Media for Enhanced Seedling Growth in Pansy (Viola tricolor)
No full textThe alarming increase of temperature in Northern areas of India makes it difficult to grow seeds due to these temperature fluctuations. Since Punjab is the hub of annual flower seed production it becomes imperative to identify suitable seed primming and growing media for proper growth and germination of seedlings of annual flower crops. Hence this investigation was conducted in PAU, Ludhiana to evaluate different pre sowing seed treatment and growing media in pansy seeds for better growth and development of seedlings. The maximum shoot length (5.75cm), root length (5.38 cm), number of leaves per plant (8.00), fresh weight (14.04g), dry weight (1.42 g) and SPAD index (34.43) was recorded through synergistic effect of GA3 @ 25 ppm + soil: cocopeat: vermicompost (1:1:1) in pansy. Therefore, it was concluded from the study that treatment combination of GA3 @ 25 ppm + soil: cocopeat: vermicompost (1:1:1) was found to be the best for almost all parameters as compared to the other treatments
Synergistic Benefits of Combined Application of Manures and Chemical Fertilizers: Enhancing Growth and Yield of Rice and Wheat
No full textThe incorporation of compost and manure with chemical fertilizer has become a key concern to sustain soil fertility. Because the nutrients are continuously depleting from the soil and consequently creating a risk to preserving soil health.
Aims: This study assesses the response of different doses of cowdung (CD), municipal solid waste compost (MSWC), oil cake (OC), and poultry manure (PM), incorporated with fertilizers on the growth, yield and protein content of BRRI dhan49 rice and BARI Gom-24.
Study Design: RCBD with 8 treatments and 3 replications.
Place and Duration of Study: Field experiment and nutrient analysis were carried out at Bangladesh Agricultural University (BAU), Mymensingh. Wheat was grown during the rabi season from October 2018 to March 2019. Again, rice was cultivated during kharif II season from August 2019 to December 2019 on the same field. Then the laboratory analysis was performed till June 2020.
Methodology: Eight treatments i.e., T0 Control (no fertilizer), T1 Recommended Fertilizer Dose, T2 (CD + NPK), T3 (MSWC + NPK), T4 (OC + NPK), T5 (PM + N), T6 (MSWC + N), T7: (CD + OC) were accommodated. Data on the growth parameters including grain and straw yields were documented after the harvest of the fully matured crop simultaneously determining the nitrogen (N) and protein content.
Results: Adoption of various combinations of compost and manures with fertilizer accorded an increase in yield contributing characters as well as the N and protein content. Integrating MSWC @ 10 t ha-1+N projected the highest grain yield (7.11 t ha-1 in rice; 4.84 t ha-1 in wheat) and straw yield (8.8 t ha-1 in rice; 5.55 t ha-1 in wheat). It also promisingly secured the highest protein content compared to all other treatments.
Conclusion: The appliance of MSWC @ 10 t ha-1 with the recommended dose of N may be endorsed for rice and wheat cultivation in the AEZ-9 region and retaining the physicochemical properties of Old Brahmaputra Floodplain soils
Effect of Agronomic Biofortification of Zn and Fe on Growth, Yield and Economics of Pigeonpea
No full textPigeonpea (Cajanus cajan) is a major leguminous crop providing substantial nutritional benefits, especially protein to millions of people worldwide. However, its yield and nutritional quality are often constrained by micronutrient deficiencies, particularly zinc (Zn) and iron (Fe). This study investigates the effects of agronomic fortification with Zn and Fe on the growth, yield parameters and overall yield of pigeonpea. The experiment was conducted through a randomized complete block design with nine treatments and replicated thrice. Agronomic fortification involved foliar application of Zn and Fe at flowering and pod development stages. Results indicated that among different treatments the combined foliar application of 0.5 % ZnSO4 + 0.5 % FeSO4 at flower and pod initiation recorded significantly higher plant height (156.7 cm), number of branches per plant (16.8), number of pods per plant (98.5), number of seeds per pod (5.4), pod weight per plant (128.5 g), seed weight per plant (83.5 g), seed yield (1056 kg ha-1) and stalk yield (2503 kg ha-1) in the fortified treatments compared to the control. Notably, the combined Zn-Fe fortification exhibited the most pronounced effects on growth and yield parameters. Overall, agronomic fortification with Zn and Fe positively influenced the growth, yield parameters and yield of pigeonpea, suggesting its potential as a sustainable strategy to alleviate micronutrient deficiencies and enhance crop productivity in pigeonpea cultivation systems
