International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad design with eight treatments and three replications. There were eight treatments viz, T1 is RDF (No spray), T2 is RDF + 1% urea spraying, T3 is RDF + 1% DAP spraying, T4 is RDF + 1% 19:19:19 (N,P,K) spraying, T5 is RDF + 1% 00:52:34 (N,P,K) spraying, T6 is RDF + 13:00:45 (N,P,K) spraying, T7 is RDF + 1% 13:40:13 (N,P,K) spraying and T8- control (no RDF, no spray). Foliar application of fertilizers (1%) is done at the flowering and pod development stage. The treatments were allotted randomly in each replication. Therecommendeddoseoffertilizer (25:50:25 NPK kg ha -1 ) was applied at the time of sowing through Urea, SSP, and MOP. The recommended cultural practices and plant protectionmeasureswereproperlytakenfrom timetotime.The plants were used for measuring phenological characteristics like plant height, the number of branches plant and number of nodule plants, the seed index by taking 100 seeds, and weight for working out the seed index on electric balance.Protein content was determined by multiplying the percent of N in the grain sample by a constant factor of 6.25 as described by A.O.A.C. (1975).The statistical method of analysis of variance was used for analyzing the data and the “F” test of significance was used for testing the null hypothesis to determine whether the observed treatment effects were real and discernible from chance effects. Results Data in respect of plant height and number of branches plant -1 influenced by different treatment. The plant height (cm)differed significantly due to different foliar applications of fertilizers in gram, T4 - RDF + 1% 19:19:19 NPK spraying at flowering and pod development recorded significantly highest plant height (59.73) cm which was found at par with T2 - RDF + 1% Urea spraying at flowering and pod development (58.77) cm however it was significantly higher than all other treatments. Significantly lowest (42.87) cm plant height was recorded with T8 - Control (No RDF, No spray). In the present study, the data revealed an increase in plant height through foliar application of 19:19:19and urea may be attributed to increasing the N status in the plant system. The number of branches plant -1 of gram was significantly influenced due to different foliar fertilizers application, T4 - RDF + 1% 19:19:19 NPK spraying at flowering and pod development recorded a significantly higher number of branches (24.20) which was found at par with T5 - RDF + 00:52:34 NPK spraying at flowering and pod development (23.40) however, it was significantly higher than all other treatments. significantly the lowest number of branches (13.19) recorded with T8 - Control (No RDF, No spray). The maximum number of branches might be due to the increased number of nodes and the development of plants due to the treatment effect and increase in the availability of nitrogen which encouraged the carbohydrate synthesis in grams as there was the availability of applied nitrogen.

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad influenced by various treatments. The mean number of nodule plant -1 was not influenced significantly by various foliar applications of fertilizers in gram. However, the mean number of nodule plant -1 at 30, 45, 60, 75, and 90 DAS were 16.98, 36.16, 40.47, 20.81, and 9.74 respectively. The seed index was not influenced significantly due to foliage-applied fertilizers. The highest seed index (8.53 g) was recorded with T5 - RDF + 1% 00:52:34 (NPK) spraying at flowering and pod development stage followed by T4 - RDF + 1% 19:19:19 (NPK) spraying at flowering and pod development (8.42 g) and T7 - RDF + 1% 13:40:13 (NPK) spraying at flowering and pod development (8.27 g). The lowest seed index (7.20 g) was recorded with T4 - Control (No RDF, No spray). The protein content (%) differed significantly due to different foliage applied fertilizers in gram, T4- RDF + 1% 19:19:19 NPK spraying at flowering and pod development recorded significantly highest protein content (19.68%) which was found at par with T7 - RDF + 1% 13:40:13 (NPK) spraying at flowering and pod development (19.37%) and T3- RDF + 1% DAP (NPK) spraying at flowering and pod development (18.75%). Significantly lowest (16.87%) protein content recorded with T8 - Control (No RDF, No spray). An increase in protein content may be due to the most important role of nitrogen in plants is mainly in its presence in the nucleic acid which is the protein structure. In addition, nitrogen is also found in chlorophyll molecules. Chlorophyllconverts sunlight energy into assimilates through photosynthesis. Therefore, the nitrogen supply to the plant will influence the amount of protein. Conclusion The foliage application of 1% 19:19:19 (NPK) or 1% 00:52:34 (NPK) or 1% 13:40:13 (NPK) spraying at flowering and pod development stage along with RDF was found beneficial and productive for improving phenological characters of a gram. For higher quality gram foliage application of 1% 19:19:19 (NPK) or 1%, 13:40:13 (NPK) or 1% DAP along with RDF was found beneficial. References A. O. A. C. 1975.
