Abstract

The present study was conducted to assess the influence of integrated nutrient management on tuberous root of radish (Raphanus sativas L.) in sandy regosol. This trial was designed in a Randomized Complete Block Design (RCBD) having seven treatments replicated four times. The treatments were recommended inorganic fertilizers (T1), 10t/ha cow dung as a basal with ½ dose of top dressing (T2), 8t/ha cow dung +2 t/ha compost as a basal +½ dose of top dressing (T3), 6t/ha cow dung +4 t/ha compost as a basal +½ dose of top dressing (T4), 4t/ha cow dung + 6 t/ha compost as a basal +½ dose of top dressing (T5), 2t/ha cow dung + 8 t/ha compost as a basal +½ dose of top dressing (T6), 10t/ha compost as a basal +½ dose of top dressing (T7). This study revealed that tuberous root diameter were significantly (P<0.01) varied at 7th week after planting. However, there were no significant change (P>0.05) in tuberous root length, fresh weights of plant and tuberous root and number of cracked roots per plot at 7th week after planting. Total yield and total marketable yield per plot showed significant difference (P<0.05) at 7th week after planting and it was high in T5 and no significant variation between T5 and T1. Further, pH and total soluble solid were same in al tested treatments. This study conclude that application of 4t/ha cow dung with 6 t/ha compost as a basal and ½ dose of recommended fertilizer as a top dressing (T5) would be more suitable for tuberous root of radish in sandy regosol.
