Abstract
The present investigation was conducted during Kharif- 2018-19 to study the “Interactive effect of biochar, FYM and nitrogen on soil properties and yield of blackgram” at Research Farm, Department of Agronomy, Dr. PDKV, Akola. The experiment was laid out in Randomized Block Design with nine treatments and three replication. On the basis of results obtained in the present investigation, highest yield and yield attributing characters of blackgram were observed with soil application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) and it was on par with treatment T7, T5, T3 and T8. The Nutrient content and uptake of (NPK) by blackgram was significantly highest in treatment where soil application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) was applied and it was on par with treatment T7, T5, T3 and T8. The test weight was significantly highest in treatment receiving soil application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) and it was found to be on par with all other treatments expect treatment T1 and Protein content of blackgram was increased due to the application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) and it was on par with treatment T7, T8, T5 and T3. Chemical properties like pH and EC show slightly changes but treatment differences were non-significant and organic carbon content significantly increased with application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) and it was on par with treatment T8, T7 and T5 and the available N, P, and K significantly increased with application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 (T9) and it was on par with treatment T8 and T7. The lower value of available N, P and K were recorded in treatment (T1) i.e. control. The bulk density was non- significant and WHC increased with application biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 and it was found to be on par with the treatments T8, T7 and T5. The significantly increase in soil microbial biomass carbon (SMBC) was recorded in treatment where soil application of biochar @ 10 t ha-1 + FYM @ 10 t ha-1 and nitrogen @ 20 kg ha-1 and it was found to be on par with the treatment T7, T8 and T5. Whereas, the lowest soil microbial biomass carbon was reported in treatment control (T1). The correlation matrix showed a positive and significant relationship between yield with various soil properties, available P (0.839**) was highly correlated with yield of blackgram followed by available N (0.785**), organic carbon (0.735**) and available K (0.713**) indicating their contribution in improving yield of blackgram.
Hence, it is concluded that the soil application of biochar @10 t ha-1 + FYM 10 t ha-1 and nitrogen 10 kg ha-1 were favourably influenced the yield, uptake of nutrient and quality of blackgram as well as slight improvement were observed in soil properties.
Description
The present investigation deals with the changes in soil fertility status and yield of crop due to use of various organic sources that alleviating the nutrient deficiency in soil, improve physical, chemical and biological properties of soil and its organic. The investigator has also tried to correlate among yield with various soil properties.
