An experiment was conducted to study the effect of fertigation levels and schedules on growth, yield and nutrient uptake of tomato under polyhouse. The treatments included 3 fertigation levels (F1- 60% of RDF, F2- 80% of RDF, and F3- 100% of RDF) and 3 fertigation schedules (S1-6 equal splits of RD of NPK at every 18 days interval, S2-9 equal splits of RD of NPK at every 12 days interval, S3-12 equal splits of RD of NPK at every 9 days interval). The results indicated that fertigation of 100 per cent RD of NPK (300:150:150 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT was found significantly superior in case of growth, yield attributes and fruit yield of tomato. However, it was at par with 80 per cent RD of NPK (240:120:120 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval up to 120 DAT. Similarly, significantly maximum nitrogen, phosphorus and potassium uptake by tomato plant was registered with fertigation of 100 per cent of RDF and 12 equal splits of NPK at every 9 days interval up to 120 DAT. It was further concluded from the study that fertigation of 80 per cent RD of NPK (240:120:120 N, P2O5, K2O kg/ha) in 12 equal splits at every 9 days interval upto 120 DAT was found to beneficial for higher growth and fruit yield of tomato under polyhouse condition during summer season.Keywords

Agronomic investigation was carried out to study the influence of nutrient management on growth yield and quality of Kharif groundnut. The results revealed that, the balanced nutrition through STCR equation proved its superiority by recording significantly maximum growth and yield attributes during both years. Application of fertilizer as per STCR (25 q ha-1) equation recorded maximum and significantly higher dry pod yield (23.08 and 24.49 q ha-1) than recommended dose of fertilized during both years. This indicates that, the application of fertilizer dose as per soil test crop response (STCR) equation achieved the yield target of 25 q ha-1 in Kharif groundnut with less than 10 per cent variation (-5.8 %). The maximum oil content (50.04 and 50.22%) was recorded under application of fertilizer dose as per soil test and maximum protein content (25.61 and 25.67%) was observed in fertilizer dose as per STCR equation and at par with fertilizer dose as per soil test during both the years. Application of fertilizer as per STCR equation to Kharif groundnut registered significantly higher total uptake of nitrogen (124.48, 126.58 kg ha-1), phosphorus, (25.93 and 25.97 kg ha-1) and potassium (77.53 and 78.92 kg ha-1) than rest of treatments.Keywords
