Impact of Organic Fertilizers on Growth and Yield of Tomato Plant Under Semi-Arid Climatic Condition of Quetta

Tomato is a vital vegetable crop which is cultivated globally and has second number after than potato but first in rank as a processing crop. The pots experiment was conducted in Agricultural Research Institute of Quetta, Balochistan. The different organic manures were used to assess the vegetative growth and yield of tomatoes. A Randomized Complete Block Design (RCBD) with 3 replications was used for the experiment. The results revealed that the adding of organic manure at quantity of 20 tons ha-1 significantly at P (chicken manure> sheep manure > cow manure > compost > no manure). Chicken as well as sheep manures had a synergistically impact on both fresh and dry weight of tomato shoots and roots as compared to the other treatments. The results indicated that the chicken manures had the best effect on overall studied parameters of tomato variety while soil with no fertilizer, as control group showed the least effect on overall studied parameters of tomato variety. As a general result using of organic fertilizers particularly in compost form had good influence on soil consistency and productivity, which consequents increase yields in long terms can be expected
