Influence of Vermicompost and Sulphur on Groundnut (Arachis hypogaea) - Wheat (Triticum aestivum) Cropping Sequence under Loamy Sand Soil

Abstract

A field experiment was conducted at RARI, Durgapura-Jaipur in irrigated coarse textured agro ecological situations during Rabi 2014-15, 2015-16 & 2016-17 to find out the effect of sulphur and vermicompost application on grain and straw yield of wheat under groundnut – wheat crop sequence. Twelve treatments were taken in randomized block design with three replications, variety Raj- 3765 of wheat was taken as test crop. Three, years pooled data revealed that significantly higher grain and straw yield was obtained where, vermicompost was applied @ 6t/ha which is at par with T5 where V. C. was applied @ 2t/ha. Soil application of V. C. @ 6t/ha + S @ 45kg /ha+ N P K   gave significantly highest grain and straw yield (50.75 & 72.44 q/ha) of wheat over treatment T1, T2, T3, T4, T7 and T10 and at par with T5 and rest of the treatment. The lowest yield was recorded in T1 (37.05& 52.15 q/ha). Three-year pooled data of ground nut revealed that soil application of vermicompost @ 6t/ha + S @ 45kg /ha+ N P K   gave significantly highest pod yield (43.15 q/ha) of groundnut over treatment T1, T2, T3, T4, T5, T7 and T10 and at par with T6 where vermicompost was applied @ 2 t/ha and sulphur was applied @ 45kg/ha (40.08 q/ha) and rest of the treatments. The lowest yield was recorded in T1 (30.51 q/ha).
