Food Challenges

It is expected that up to 2050, human population will be doubled. Agricultural researchers are striving their best to meet the food challenges. To get the higher yield, nitrogenous fertilizers use is also being increased. Nitrogenous fertilizers play vital roles in different plant’s growth and developmental processes. But, excessive use of nitrogen is no more beneficial to plants. Only 30 to 50% nitrogen use efficiency is recorded in plants, the remaining nitrogen is used by soil microbes, leached down in soil profile or volatilized. Different agronomical practices have been practiced and suggested for the general cultivation. Proper use of these agronomical practices can increase the crop yield and nitrogen use efficiency.

Absolute Control

 An experiment was conducted to study the nitrogen use efficiency of nutrient enriched biochar (NEB) from sugar industry wastes with seven treatments comprising T1 (absolute control), T2 (50% RD of PK through NEB), T3 (75% RD of PK through NEB), T4 (100% RD of PK through NEB), T5 (125% RD of PK through NEB), T6 (50% through NEB + 50% through inorganic fertilizer) and T7 (100% RD of PK through inorganic fertilizer) in RBD using the rice variety TRY 3. In all treatments, nitrogen was supplied based on LCC reading. The result revealed that application of N through NEB could release the nitrogen slowly and steadily, thereby increasing the nitrogen use efficiency and crop yield. Since the yield of T3 treatment (6103 kgha-1) was on par with T4 (6165 kgha-1) and T5 (6269 kgha-1) treatments, which indicated that the plants received the essential nutrients in required quantities at 75 % RD of PK through NEB itself. On optimization of graded levels of NEB, the application of 75% RD of Pk through NEB was found to be the best treatment with respect to nitrogen use efficiency and grain yield in response to the quantity of nitrogen applied.
