Abstract:
Nitrogen has direct role on development and yield of crops. With an objective to find out the best treatment combination for nitrogen uptake, this research was conducted using ten different treatments with five replications in RCBD design. The treatments were T1 (Control), T2 (2% compost added), T3 (2% compost + NPK full dose), T4 (T3+ Biochar @ 4t/ha), T5 (T2 + biochar @ 4t/ha + 50ml cattle urine per pot), T6 (T2 + biochar @ 4t/ha + 50ml cattle urine at hotspot), T7 (T3 + 8t/ha biochar), T8 (T5 at 8t/ha biochar), T9 (T6 at 8t/ha biochar), T10 ( compost at 4%). Srijana variety of tomato was used for this research. Observations were made for Soil Plant Analysis Development (SPAD) reading, plant height, number of fruits, fruit yield and soil nitrogen content and the obtained data were analyzed using Analysis of Variance (ANOVA). SPAD reading showed a non-significant variation among the treatments. The correlation between SPAD readings and total nitrogen in soil was found statistically non significant and least positively correlated. Highest mean value of plant height was obtained from T2 of 1-7.03cm. T3 gave the highest number of fruits of 68. There was significant difference on total fruit yield having T10 the highest fruit yielding treatment of 1.523kg. There was high significant difference on total soil nitrogen and most of the soil had total nitrogen content ranging from high to medium with T1 having lowest nitrogen content
