Influence of phosphorus and panchagavya levels on summer blackgram

Abstract

A field experiment was conducted during zaid (summer) season of 2023 at Crop Research Farm Department of Agronomy. The treatments consisted of 3 levels of phosphorus [100% (40 kg/ha), 75% (30 kg/ha) and 50% (20 kg/ha)] and panchagavya (2, 4 and 6%) along with recommended doses of nitrogen and potash and a control (20-40-20 kg N-P-K/ha). The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. Application of 100% phosphorus (40 kg/ha) along with foliar spray panchagavya 4% (Treatment 2) recorded highest plant height (32.70 cm), highest number of branches per plant (9.27), highest number of nodules per plant (17.00), highest dry weight (13.4 g), pods per plant (17.93), seeds per pod (8.33), test weight (37.73 g), seed yield (932.13 kg/ha) and stover yield (1894.53 kg/ha). The aforesaid treatment also recorded maximum gross return (INR 82148.80/ha), net return (INR 53299.80/ha) and B:C ratio (1.85).
