Yield and nutrient uptake by tomato as influenced by weed management practices

Abstract

Field experiment was conducted during the year 2016-17 at Navsari Agricultural University, Navsari. The treatment weed free check (T2) noted significantly the highest marketable fruit yield (31.67 t/ha) which remained at par with treatments T5 and T3. In case of uptake by tomato fruits, treatment T2 reported significantly higher uptake of N and P2O5 but, it was at par with treatments T5, T3, T10, T9 and T7. However, uptake of K2O by fruits found significant higher in treatment T5 and remained at par with treatments T2, T10, T3, T9, T7 and T6. Similarly, N and K2O uptake by tomato plant was significantly higher with treatment T2 and remained at par with treatments T7, T3, T5 and T9. While, P2O5 uptake by tomato plant was highest with treatment T9 found at par with all the weed management practices except treatments T4, T6 and T8. The N, P2O5 and K2O uptake by weed was significantly lower in treatment T2. The highest WCE (78.22 %) was recorded in treatment T2 followed by the treatments T3 and T5. However, the B: C ratio of the treatment T5 was higher, which was closely followed by the treatments T2 and T3.
