Effect of Micronutrients Application on Nutrient Removal And Performance of Urd Bean in Sandy Loam Soil

Abstract

An experiment was conducted to study the effect of micronutrients application on nutrient removal and performance of Urd bean in sandy loan soil during Kharif 2007 Eight different treatments were replicated thrice in a randomized block design. The soil of experimental site was low in organic carbon and medium in available phosphorus and potassium. Treatments were recommended NPK (T1), recommended NPK + Fe @ 2.5 mg kg' 1 + (T2), recommended NPK + Mo @ 1.0 mg kg·1 (T3) , recommended NPK + B @ 2.5 mg kg'1 (T4), recommended NPK + Fe @ 2.5 mg kg'1 + Mo@ 1.0 mg kg'1 (T5), recommended NPK +Fe@ 2.5 mg kg'1 + B @ 2.5 mg kg'1 (T6}, recommended NPK + Mo@ 1.0 mg kg·'+ B@ 2.5 mg kg·1 (T7), recommend NPK +Fe@ 2.5 mg kg'1 + Mo@ 1.0 mg kg'1 + B @ 2.5 mg kg'1 (T8) . Significantly lower grain yield, effective nodules micronutrient content in plant sample were obtained with T, treatment where only recommended NPK was applied The treatment where recommended NPK + Fe @ 2.5 mgkg'1 + Mo @ 1.0 mgkg' 1 + B @ 2.5 mgkg 1 produce stgnificantly the htghest gratn and straw yteld and micronutrient content and tl was statistically at par with the treatments where recommended NPK +Fe@ 2.5 mgkg'1 + Mo@ 1.0 mgkg·1 (T5) or recommended NPK + Fe@ 2.5 mgkg'' + B@ 2.5 mgkg'1 (T6) were applied and significantly superior over rest of the treatments. From the above study it also seems that application of micronutrient along with recommended NPK improved its content in soil in comparison to control. The chemical properties of soil in the rest of the treatments improved slightly.
