Abstract: Statistical disparity was not observed with respect to physical properties of soil viz., bulk density and aggregate stability during the two consecutive years of study both under rain fed and protective irrigated condition. Whereas, slightly higher and lower values of bulk density and aggregate stability were observed with control (T1) respectively. Supply of 100 per cent N through organic manures viz., FYM, sheep penning leaf compost, sheep manure, enriched groundnut shells (T4, T9, T6, T8 and T10) recorded significantly higher water holding capacity and infiltration rate over substitution of 50 per cent N through urea with the above organic manures (T3, T5, T7 and T11) and recommended dose of fertilizers (T2) both under rain fed and protective irrigated condition. The deflated stature of above said parameters were recorded with control (T1). At all the stages of the crop growth, significantly highest moisture content in the soil was recorded with supply of 100 per cent nitrogen through FYM (T4), which was at par with application of 100 per cent nitrogen through sheep penning (T9), leaf compost (T6), sheep manure (T8) and enriched groundnut shells (T10) i.e., where 100 per cent N was supplied through organics. However, it was comparable with substitution of 50 per cent nitrogen through sheep manure (T7) during the second year of investigation under both the situations.
Supply of 100 per cent of nitrogen through sheep penning (T9) recorded significantly higher pod and haulm yield of groundnut, which was however comparable with 50 per cent nitrogen through urea + 50 per cent nitrogen through FYM (T3) and recommended dose of fertilizer (T2) under rain fed situation. Whereas under protective irrigation, which was in turn comparable with supply of 50 per cent nitrogen through urea + 50 per cent nitrogen through leaf compost (T5).
