Nutrient Uptake of Maize as Influenced by Intercropping with Different Genotype of Groundnut under Temperate Kashmir Valley

Abstract

A field experiment on ‘Nutrient uptake of maize as influenced by intercropping with different genotype of groundnut under temperate Kashmir valley” was conducted at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Wadura, Sopore during 2021 and 2022. The experimental soil exhibited silty clay loam characteristics with adequate drainage and normal levels of both reaction and salinity. The experimental treatments comprised of sole crops and various row proportions of maize intercropped with groundnut. The experimental design was randomized complete block design, consist nineteen treatments that were replicated three times. Treatment comprised of T1 (Sole maize, 60 cm), T2 (sole paired maize, 75-45-75 cm), T3 (Sole paired maize,90-30-90 cm), T4 (Sole groundnut TG-84), T5 (Sole groundnut TG-37-A), T6 (Sole groundnut TG-88), T7 (Sole groundnut TG-89), T8 Alternate row of maize + groundnut TG- 84 (30 + 30 cm ),T9  Paired row of maize  + groundnut TG- 84 (75-45-75 cm maize in between 25-25 cm groundnut),T10  Paired row of maize  + groundnut TG- 84 (90-30-90 cm maize in between 30-30 cm groundnut), T11 Alternate row of maize  + groundnut TG- 37-A (30 + 30 cm ) T12 Paired row of maize + groundnut TG- 37-A (75-45-75 cm maize in between 25-25 cm groundnut), T13 paired row of  maize  + Groundnut TG- 37-A (90-30-90 cm maize in between 30-30 cm groundnut), T14  Alternate rows of maize + Groundnut TG- 88 (30 + 30 cm),T15 Paired row of maize  + groundnut TG- 88 (75-45-75 cm maize in between 25-25 cm groundnut), T16 Paired row of maize + groundnut TG- 88 (90-30-90 cm maize in between 30-30 cm groundnut), T17 Alternate rows of maize + groundnut TG- 89 (30 + 30 cm), T18 Paired row of  maize + groundnut TG- 89 (75-45-75 cm maize in between 25-25 cm groundnut), T19 Paired row of maize+ groundnut TG- 89 (90-30-90 cm maize in between 30-30 cm groundnut). The two years of result revealed that intercropping increased the total N, P and K uptake and enhancing yield of both the crop. Total N, P and K uptake was recorded significantly higher with paired row of maize (75/45 cm spacing) in intercrop with groundnut variety TG-37-A as compared to sole maize. In intercrop N, P and K uptake was recorded significantly higher in sole groundnut variety TG-37-A followed by TG-84, TG-88 and TG-89.
