Background: Pulses are important food crops that can play a major role in achieving food security, nutrition, and human health, contributing to the sustainability of agriculture and aiding the mitigation and adaptation to climate change. The nutrient uptake is directly or indirectly affected by many factors like total concentration as well as available quantity of different nutrients, root development, aeration, water potential, climatic conditions and other related soil parameters. Aims: A field experiment was carried out to find out the effects of different manures along with inorganic fertilizers on nutritional status of two mungbean varieties. Study Design: Experimental treatments consisted of eight combinations of each manure and inorganic fertilizers with Soil Test Base (STB). Results: The results showed that integrated effects were found significant on Ca, Zn and Mn contents in seed and P, Mg, Fe, Cu, Zn and Mn contents in stover. The highest N (4.34%), Mg (0.48%), P (0.56%) contents in seed and N (1.52%), Mg (0.78%) and B (30.67 µg g-1) contents in stover was obtained by the application of 3 t ha-1 poultry manure + 70% STB. The highest seed protein content was found from the same treatment. On the other hand, the highest Zn, Mn, Cu and S contents in seeds, and Zn, Fe and K contents in stover were obtained from 3 t ha-1 vermicompost + 70% STB. The treatment of 3 t ha-1 poultry manure + 70% STB produced the highest uptake of N, P, K, Ca, Mg, Zn, Mn, and Cu in seeds and the highest uptake of Mg, Fe and B was found with stover. The nutrient contents of seeds were positively and significantly correlated with each other. In Principal Component Analysis (PCA), the first two principal components accounted for approximately 81.80% of the total variability. BARI Mung-6 appeared as the best variety and poultry manure @ 3 t ha-1 along with 70% inorganic fertilizers treatment for the better nutritional quality of Mungbean. Conclusion: It was observed that different treatments performed differently in respect of nutrients contents and uptake of seed and stover, and protein contents. From the above experimental findings, it is concluded that BARI Mung-6 appeared as the best variety and poultry manure @ 3 t ha-1 along with 70% IF should be applied for getting better nutritional mungbean seed with higher protein contents under the agroclimatic condition of BARI. |
