“…As pigeonpea is deep rooted legume it has ability to draw the fixed phosphorus from deeper layers of Hybrid Pigeonpea (ICPH 2740) Nodular Activity and Biological Nitrogen Fixation as Influenced by Agronomic Practices soil by releasing certain root exudates and acids (Piscidic acid) but, the nitrogen requirement should be meet my biological nitrogen fixation (Singh et al, 2016). So, the recommended dose of nitrogen is very less, the required nitrogen demand of crop should be met by biological nitrogen fixation (Tigga and Singh, 2019), but this nodulation activity again depends upon the many external and management factors (Kumar and Dart, 1987). For successful nodulation certain agronomic practices at field level i.e.…”

Background: To explore the impact of agronomic practices on nodulation, nitrogenase activity and biological nitrogen fixation in hybrid pigeonpea, a field investigation was under taken at BW5 block ICRISAT development center (IDC), International Crops Research Institute for Semi-Arid Tropics (ICRISAT), Patancheru, Hyderabad, during kharif, 2021 and 2022. Methods: The seedlings were raised in portrays in advance to onset of monsoon during last week of May (28th May in 2021 kharif and 30th May in 2022 kharif) in both the years by filling portrays with cocopeat and vermicompost in 1:1 ratio. Transplanting of 24 days and 25 days old seedlings were done on 20th June in 2021 kharif and 23th June in 2022 kharif, respectively, on the same day of dibbling in the main field at 100 cm × 100 cm ,120 cm × 120 cm square geometry and 150 cm × 60 cm. Nutrient management treatments were imposed one week after sowing. Result: Among the planting methods higher nodule number and nitrogenase activity with transplanting compared to dibbling. 120 cm × 120 cm found higher nodule number plant-1 and nitrogenase activity but biological nitrogen fixation was higher with 100 cm × 100 cm ha-1 basis. With respect on nutrient management practices, control performed well in terms of higher nitrogenase activity and biological nitrogen fixation and on par with integrated approach of 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium. So, with transplanting method of establishment, 100 ´ 100 cm square plant geometry and 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium was recommended agronomic practices for hybrid pigeonpea.

“…Moreover, most of the available varieties and hybrids of pigeonpea are photo-sensitive, meaning they enter the reproductive stage when they receive the optimum day length, regardless of the actual sowing time (Varatharajan et al, 2019b). As a result, source development in these plants is constrained (Tigga and Singh, 2019). To address the issue of source-sink imbalances and ensure proper plant development, the concept of transplanting emerged as an alternative to conventional dibbling methods.…”

Background: A two-year field study was conducted at the ICRISAT research farm during the rainy seasons of 2021 and 2022 to investigate the impact of crop geometry, crop establishment method and sustainable nutrient management practices on nutrient availability pattern and growth of hybrid pigeon pea. Methods: The experiment followed a split-split plot design. The collected data was analysed using radar graph and heat maps for nutrient availability and dry matter respectively. Result: Data revealing that transplanted plots registered higher nutrient availability and proportionate root and total dry matter production at various growth stages. Among plant geometry the root and total dry matter production was higher with 100×100 cm. when considering planting methods, transplanting with a square system of 100×100 cm, combined with an integrated nutrient management approach consisting of 150% (or) 100% soil test based NPK, vermicompost at a rate of 5 t ha-1, phosphate-solubilizing bacteria (PSB) and seed treatment with Rhizobium, resulted in average of 31.5% higher dry matter production over alone inorganic nutrient management practices. Thus, a square geometry of 100×100 cm, along with sustainable integrated nutrient management (100% soil test based NPK, vermicompost at a rate of 5 t ha-1, PSB and seed treatment with Rhizobium), resulted in higher nutrient availability and dry matter production. These findings highlight the importance of careful selection of planting methods, crop geometry and nutrient management practices for maximizing the nutrient mining for production of high dry matter production of hybrid pigeonpea.
