【 摘 要 】

Excessive use of chemical fertilizers causing a serious threat to the agro-ecological system, developing resistance to pest and declining food safety. Under current scenario, the application of bio-organic nutrients sources become imperative to sustain the productivity of arable farming. Thus to study the possible use of bio-organic sources of nutrients in soil fertility, crop quality and saving the application cost of chemical fertilizer, a pot experiment was conducted in green-house at Land Resources Research Institute, NARC Islamabad. Integrated effects of bio-organic fertilizers such as phosphate solubilizing bacteria (PSB), vermicompost (VC) along with chemical fertilizer was investigated on soil-plant nutrients contents, growth and yield of tomato. Post-harvest results showed that the integrated use of bio-organic fertilizers with chemical fertilizer significantly increased the agronomic yield (Plant height and chlorophyll content) and fruit yield (Number of fruits, fruit weight, fruit diameter and yield) in tomato. The maximum plant height (161.24cm), chlorophyll contents (61.2), number of fruits (19), fruit weight (55g), fruit diameter (45.6a) and fruit yield (1.39 Kg/plant) were recorded in the treatment T5 where VC+PSB+75%RD were applied and minimum in treatment T1 (control). Treatment T5 has increased 117% fruit yield over control. The highest N (2.05% and 2.89%), P (0.33% and 0.50%) and K (2.32% and 6.67%) concentration in shoot and fruit of tomato respectively were found in treatment T5 (VC+PSB+75%RD). Similarly, in soil the highest N (4 mg Kg-1), P (0.66mg Kg-1) and K (3.53mg Kg-1) was recorded in treatment T6 (VC+PSB+100RD). Thus, study results recommend that the integrated use of bio-organic sources with appropriate proportion of chemical/synthetic fertilizers is best option of fertilizer savings and to achieve maximum benefits regarding quality and yield.
