Abstract:
The experiment was conducted in Crop Research Farm in the Department of Agronomy, SHUATS, Prayagraj (U.P.) during summer season of 2022 on greengram crop. The soil of the experimental field was sandy loam in texture, slightly alkaline reaction (pH 6.8) with low level of organic carbon (0.332%), available N (225 Kg/ha), P (14.60 kg/ha) and higher level of K (213.50 kg/ha). The treatments consisted of three different organic source of nutrient (Farm yard manure 8t/ha, Poultry manure 2.5 t/ha, Vermicompost 2.5 t/ha) and methods of application of iron (Soil application 20 kg/ha FeSO₄, Foliar application 0.5% FeSO₄ at 20 DAS, Soil Application 10 kg/ha FeSO₄ and Foliar application 0.25%FeSO₄ at 20 DAS) and a control. The experiment was laid out in randomized block design with ten treatments and replicated thrice. Results revealed that, Application of Poultry Manure (2.5 t/ha) along with Soil Application (10 kg/ha FeSO₄) followed by (0.25% FeSO₄) (Foliar Application at 20 DAS)) recorded highest plant height (42.03 cm),number of nodules (12.50), dry matter accumulation (40.41 g/m²/day number of pods per plant (25.44), seeds per pod (12.50) and test weight (40.41 g) which attributed to higher seed yield (2030 kg/ha) and stover yield (4420 kg/ha).Result also shows, highest gross returns (160741.50 INR/ha), net returns (120346.5 INR/ha) and benefit cost ratio (2.97).
