Substitution of Nitrogen and Phosphorous by Bio-Inoculants and Their Effect on Growth Parameters, Yield Attributes and Yield of Barley

A field experiment was conducted during Rabi season of 2022-2023 at Rajoula Agriculture farm, of Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya Chitrakoot, Satna (M.P.). The present experiment having 13 treatment combinations replicated thrice in randomized block design. Barley variety HUV-113 was grown with recommended agronomic practices. On the basis of the results emanated from present investigation, it could be concluded that application of T11 [100 % N & P + PSB + Azotobacter + 100 % K] significantly recorded maximum growth parameters of barley such as plant population plot-1 (41.56 m-2), plant height (91.78 cm), and number of tillers (87.74) and maximum yield attributing characters such as no. of spike (73.38 m-2), spike weight plant-1 (51.20), number of spikelet (256.19) and test weight (45.76 g). Similarly highest grain yield (40.19 q ha-1) and straw yield (62.71 q ha-1), with application of treatment T11 [100 % N & P + PSB + Azotobacter + 100 % K] in comparison to all the treatments. While minimum value of all the growth parameters, yield components and yield were associated with the treatment T1 [Control].

Efficient Use of Nano-fertilizer for Increasing Productivity and Profitability along with Maintain Sustainability in Rice Crop: A Review

The need for food and the expanding global population have put enormous pressure on agriculture to increase crop yield while preserving sustainability. Since rice is a staple diet for millions of people, novel methods are needed to increase yields without harming the environment. The possible advantages of using nano fertilizers in rice farming are examined in this abstract in order to raise yields, increase farmer profitability, and ensure long-term sustainability. Nano-sized carriers created for effective nutrient delivery to crops are called nano fertilizers, an innovative application of nanotechnology in agriculture. Their special qualities, such as their large surface area and regulated release mechanisms, allow for the targeted supply of nutrients to rice plants, improving nutrient uptake and utilization. Nano-fertilizers successfully optimize nutrient availability as a consequence, increasing crop output. According to studies, using nano fertilizers in rice farming increases grain yields because plants are better able to absorb and assimilate nutrients. The crop's resistance to environmental challenges and disease strains is strengthened as a result of this enhanced nutrient utilization, which also boosts yield and contributes to sustainable rice farming practices. Furthermore, nano fertilizers offer cost-effectiveness and increased profitability for farmers. Despite their initial higher cost, the efficient nutrient delivery of nano fertilizers reduces the overall application rate required compared to conventional fertilizers. This reduction in input costs translates to improved profitability for farmers, promoting economic sustainability in rice production.
