RÉSUMÉ
Enhancing the production potential and socio- economic level of farmers, altogether 325 front line demonstrations on field pea were laid out comprising 325 farmers covering the total area 160 ha with demonstration plots ranging from 0.20 to 1.0 ha during the year 2015- 16 to 2022- 23 in 14 different villages of Khowai district of Tripura to disseminate the production technology of improved varieties viz., Malviya Matar- 15 (HUDP- 15), Prakash (IPFD 1-10), Aman (IPF 5-19). Field diagnostic visits, regular inspection, farmer’s trainings, group discussion, field days ensured application of balanced and optimum doses of nutrient, and timely plant protection measures. The productivity ranged from 11.50 to 13.50 q/ ha with average yield under demonstration recorded 12.21 q/ ha under improved technology on farmers field as against a yield ranged from 6.75 to 8.50 q/ ha with a mean of 7.52 q/ ha recorded under farmers practice. However, in the demonstration plot the yield enhancement due to technological intervention was 62.15% over the farmer’s practice. An average net returns of Rs 24,441/- at demonstrations plot, while the average net returns from farmers practice is Rs 7218. The additional cost of Rs 5440 gave additional net return of Rs. 17,223/ ha. The increased cost benefit ratio was also estimated; it ranged from 1.56 to 1.97 in recommended practices and 1.11 to 1.36 in farmers practice. An extension gap of 4.69 q/ ha was found between demonstrated technology and farmers practice, technology gap being observed 12.41 q/ ha, whereas technology index 49.87%. Therefore, cluster front line demonstration of field pea was effective for increasing the productivity of field pea and changing the knowledge, attitude and skill of the farmers. This created greater awareness and motivated the other farmers to adopt improved practices of field pea.
RÉSUMÉ
Present study was undertaken to estimate the G x E interactions and identify the stable genotypes for yield traits in field pea. A total of 43 field pea genotypes were evaluated in Randomized Complete Block Design (RCBD) in three replications along with three different dates of sowing at BSP Soybean Unit, Department of Genetics and Plant Breeding, College of Agriculture, JNKVV, Jabalpur during Rabi Season 2022-2023. The analysis of variance was applied on 16 different quantitative traits both individually and pooled under various environmental conditions. The stability analysis for seed yield per plant was assessed using Eberhart and Russell's model, revealing significant variations among different genotypes and environmental conditions. The mean squares attributed to both environments and genotype-environment interactions (E + G x E) indicated significant interactions between genotypes and environments. Further, partitioning of genotype-environment (linear) interactions was found to be highly significant for seed yield per plant. Genotypes Shikha, KPMR 485 and HFP 94-12 were found ideal and stable genotypes for seed yield per plant as that possessed mean value higher than general mean, regression coefficient near to unity (Bi=1) with minimum deviation from regression (S2di~0). Thus, identified stable genotypes can be utilized for different seasons and regions for obtaining the stable yield performance.
RÉSUMÉ
A field experiment was conducted in a farmer field of Bundi district, Rajasthan, Department of Environmental Science and Natural Resources Management College of Forestry, Sam Higginbottom University of Agriculture, Technology and Sciences Prayagraj, during Rabi 2020-2021. The experiment used a factorial randomized block design with three different planting dates: D115 October, D2–5 November, and D3– 25 November, as well as three different varieties: V1- Annapurna, V2-Azad -111, and V3- SS- 10. The findings discovered The maximum germination percentage (78.51%) and lowest germination percentage (66.78%) of seeds per plot were found in plots D1 and V1 (15th October + Annapurna). The maximum number of branches (4.00) were found in D1 and V3 (15th October + SS-10), while the lowest number of branches were found in D3 and V1 (25th November + Annapurna) (2.33). D1 and V1 (15th November + Annapurna) reported the highest plant height of 26.00, 91.38, and 124.15cm at 30, 60, and 90 DAS, whereas D3 and V3 (25th November + SS-10) recorded the minimum plant height of 19.00, 25.54, and 67.95cm at 30, 60, and 90 DAS. D3 and V3 (05th November + SS-10) had the highest blooming percentage (50.41), whereas D3 and V2 (25th November + Aazad-111) had the lowest flowering percentage (46.18). D1 and V3 (15th October + SS-10) had the highest seeds/pods (7.0), whereas D3 had the fewest (4.0).D2 and V3 (05th November + SS-10) had the highest grain yield (12.68), whereas D3 and V1 (25th November + Annapurna) had the lowest grain yield (11.01). Variety-1 plant height was shown to have a substantial positive relationship (Annapurna).
RÉSUMÉ
During Rabi 2022, a field trial was conducted at the SHUATS Agriculture Crop Research Farm in Prayagraj. The soil in the experimental plot was sandy loamy, with a near-neutral soil response (pH 7.1), low organic carbon content (0.36%), available nitrogen (171.48 kg/ha), available phosphorus (15.2 kg/ha), and had an effective soil. K (232.5 kg/ha). The experiment was set up with a randomized block design in which he repeated nine treatments three times, based on a one-year experiment. The treatments are T1: Sulphur 20 kg/ha-1 + Mo 0.5 kg/ha-1, T2: Sulphur 20 kg/ha- 1 + Mo 1.0 kg/ha-1, T3: Sulphur 20 kg/ha-1 + Mo 1.5 kg/ha-1, T4: Sulphur 30 kg/ha-1 + Mo 0.5 kg/ha- 1, T5: Sulphur 30 kg/ha-1 + Mo 1.0 kg/ha-1, T6: Sulphur 30 kg/ha-1 + Mo 1.5 kg/ha-1, T7: Sulphur 40 kg/ha-1 + Mo 0.5 kg/ha-1, T8: Sulphur 40 kg/ha-1 + Mo 1.0 kg/ha-1, T9: Sulphur 40 kg/ha-1 + Mo 1.5 kg/ha-1, T10: Control are used. The application of Sulphur 40 kg/ha-1 + Mo 0.5 kg/ha-1, recorded significant Plant height (56.25 cm), Number of nodules/plant (9.00), Plant dry weight (22.13 g/plant), maximum pods/plant (19.00), Seeds/pod (8.21), Test weight (35.45 g), Seed yield (2.29 t/ha).
RÉSUMÉ
The field experiment was conducted during Rabi season of 2022 at the Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (UP) to examine the effect of liquid organic manure on growth and yield of Field Pea (Pisum sativum L.). The finding showed that field pea growth characteristics steadily improved with the maximum application of Dasagavya (250 l/ha) + spraying. This treatment resulted in significantly higher plant height (97.14 cm), Maximum number of nodules (28.13), plant dry weight (33.18 g), number of pods/plant (22.18), number of seeds/pod (4.16), seed yield (2.04 t/ha), and harvest index (40.16%), but in Stover yield the Dasagavya (250 l/ha) + seed inoculation and Spraying treatment (4.27 t/ha) was significantly greater. It is concluded with this data that spraying of Dasagavya is the most remunerative, profitable and economically efficient.
