Loss of seed quality in soybean is a serious problem in tropical and subtropical region. Foliar application of salicylic acid (SA), GA3 and acetyl salicylic acid (50 ppm) at seedling and pod filling stage, K2HPO4 (2%), a-tocopherol (100 ppm) at flowering and pod filling stage was done on soybean varieties – NRC 7 and JS 335. Foliar application of SA showed positive effect on seed yield, seed health, germination and seed vigour during storage. Plant height was significantly improved by the GA3 spray in both the varieties. Significantly higher seed yield was obtained with foliar spray of a-tocopherol. Application of SA was found effective to protect plants from various diseases to get quality seed. a-Tocopherol and K2HPO4 treatment significantly reduced MDA production in seeds. a-Tocopherol application increased super oxide dismutase activity as a result the lipid peroxidation of seed during storage was significantly reduced. Application of a-tocopherol, K2HPO4 and salicylic acid improved the storage or keeping quality of soybean seed.

A field experiment was conducted on sandy clay loam soils of Tirupati Campus of ANGR Agricultural University, Andhra Pradesh to optimise the sowing time and nutrient needs of rabi pigeonpea [Cajanus cajan (L.) Millsp.] for its sustained productivity and profitability. Three sowing times: II FN of September, I FN of October and II FN of October; three nutrient levels (N-P2O5-K2O kg ha-1): 10-40-0, 20-50-10 and 30-60-20 and two foliar treatments: NAA (25 ppm) and DAP (2%) at 60 DAS, 60 and 80 DAS were tested on LRG 41 pigeonpea cultivar in split-split plot design, replicated thrice. Earliest sown pigeonpea (II FN September) resulted in significantly higher seed yield (1700 kg ha-1) and net returns ( 32239) due to improvement in yield attributes like pod bearing branches plant-1, number of pods branch-1, number of seeds pod-1 and test weight. Highest nutrient level (30-60-20 NPK ha-1) produced significantly higher seed yield (1589 kg ha-1) and net returns (28448) due to improvement in yield attributes. Foliar application of NAA (25 ppm) and DAP (2%) applied at 60 and 80 DAS recorded significantly highest seed yield (1434 kg ha-1) and net returns (24111) due to its positive effect on pigeonpea yield attributes. Benefit:cost ratio was significantly high (2.71) due to earliest sowing, highest level of nutrient supply (2.46) and foliar application of NAA (25 ppm) and DAP (2%) applied at 60 and 80 DAS (2.26). Early sowings resulted in significantly higher seed yields at higher levels of nutrient supply. Foliar application of DAP (2%) at 60 and 80 DAS recorded significantly higher pigeonpea yield with early sowings. Early sown pigeonpea resulted in significantly higher seed yield at all levels of nutrient supply and foliar applications. Rabi redgram gave optimum yield and economic returns sown during II FN of September with 30-60-20 kg N, P2O5 and K2O ha-1 along with foliar spray of NAA (25 ppm) and DAP (2 per cent) twice at 60 and 80 DAS.
