Long term fertilizer management for Pearl millet (Pennisetum glaucum L)-Wheat (Triticum aestivum) cropping sequence for soil sustainability and yield based on soil test crop response approach

摘要

Soil test crop response (STCR) approach based field experiment was conducted for five years on pearl millet - wheat cropping sequence. The application of fertilizers as per STCR target 25 q/ha with FYM + biofertilizers for pearl millet and both targets 30 and 40 q/ha for wheat were achieved. Highest net monitory returns were achieved for STCR target 25 q/ha with FYM + biofertilizers for pearl millet and STCR yield target 30 q/ha for wheat. Application of FYM + biofertilizers for pearl millet crop increased the productivity of soil and yield of succeeding wheat crop. The soil nutrient status was also improved during the five year of experiment.
