Abstract:

An experiment was conducted to reveal the effect of nutrients combinations on plant pigments and yield in Bt cotton under rainfed condition in kharif season of 2011-2012. The experiment was laid out in randomized block design with ten treatments (T1 to T10) replicated thrice. Data on total chlorophyll, anthocyanin and dry matter yield at square formation, boll development, boll bursting and harvest stage whereas the seed cotton yield at harvest stage was collected and analysed. It was found that the chlorophyll and anthocyanin content, dry matter yield and seed cotton yield were influenced by nutrient combinations. Total chlorophyll content in leaves was highest with nutrient combination of T9 (Recommended dose of nitrogen + phosphorus + potassium + sulphur + magnesium + zinc +boron spray). Among all the nutrient combinations the highest anthocyanin content was found in T1 (control) and lowest anthocyanin content was observed in T8 (Recommended dose of nitrogen + phosphorus + potassium +sulphur + magnesium + zinc) followed by T9. Therefore, T8 and T9 was found to be preventive for cotton reddening than T10 [Recommended dose for Bt cotton (125:62.5:62.5)+S] and T1. Highest dry matter yield 179.2 plant-1 followed by 177.3 g plant-1 was recorded with T10 and T9, respectively. T10 produced highest 19.22 q ha-1 followed by T9 with 19.04 q ha-1 seed cotton yield. Therefore, considering plant pigments yield, T9 can be recommended for growing of Bt cotton under rainfed condition.
