Abstract:A field experiment was carried out during
rabi, 2020 at Agricultural Research Station, Adilabad, under Professor Jayashankar Telangana State Agricultural University (PJTSAU). The experiment comprises of 6 treatmental combinations and laid out in split plot design. The main plots are without soybean residue incorporation and with soybean residue incorporation. Each main plot is sub divided into 6 subplots
viz., Control (0% RDF) (T1), 100% RDF (20: 50: 20 kg ha-1 NPK)(T2),
Rhizobium seed treatment @ 25 g kg-1 seed + PSB soil application @ 5 kg ha- 1(T3),
Rhizobium seed treatment @ 25 g kg-1 seed + PSB soil application @ 5 kg ha-1 + 75% RDN and 75% RDP(T4),
Rhizobium seed treatment @ 25 g kg -1 seed + PSB soil application @ 5 kg ha-1 + 50% RDN and 75% RDP(T5) and
Rhizobium seed treatment @ 25 g kg-1 seed + PSB soil application @ 5 kg ha-1 + 50% RDN and 50% RDP(T6).
Results revealed that all the growth parametersi.e. Plant population, plant height, dry matter production, total number of pods, test weight, seed yield, stover yield and harvest index of chickpea significantly highest under residue incorporation of soybean. Among all treatments application of 100% RDF recorded highest parameters. However, that was on par with 75% RD of P along with biofertilizers and 75% N along with biofertilizers. Saving of 25 percent cost on inorganic fertilizers without decreeing the optimum economic yields is possible by adopting 75% N and 75% P fertilizers in combination with biofertilizers.
