“…Application of nitrogen at 120 Kg/ha recorded significantly higher dry matter yield (143.4 q/ha), this is due to better partitioning of photosynthates with application of nitrogen which, resulted high dry matter content and green forage yield that led to increased dry matter yield. This is in accordance with the results of Damame et al, 2013 [5] , Kumar et al, 2018 [6] and Yadav et al, 2019 [4] .…”

A field experiment was conducted at zonal agricultural research station, V. C farm, mandya during summer 2019 to study the response of multi-cut pearl millet genotypes to varied levels of nitrogen and to identify the optimum and economical level for higher green forage yield and quality. The study revealed that, the variety Giant bajra national check recorded significantly higher green forage and dry matter yield (608.0 and 114.9 q ha -1 respectively), net monetary returns (Rs.56,346 ha -1 ) and agronomic efficiency of nitrogen (632.0 Kg green fodder yield per Kg of N). However the variety HTBH-4902 recorded significantly higher crude protein yield (9.13 q ha -1 ) and it was on par with variety Giant bajra (8.72 q ha -1 ). Application of 120 kg N ha -1 significantly recorded higher green forage, dry matter and crude protein yield (741.1 q, 143.4 q and 12.57 q ha -1 respectively) and net monetary returns (Rs.72,234 ha -1 ). The application of nitrogen at 40 Kg per hectare recorded higher agronomic efficiency of nitrogen (542.0 Kg green fodder yield per Kg of N).

“…The number of grains per ear, 1000-grain weight, grain, and biological yields were increased under urea + FYM application combined with RB. These improvements are linked with continuous nutrient availability as FYM slowly releases N, and leaching or volatilization losses are reduced [65,66]. Furthermore, seed inoculation with RB bacteria improved N availability in soil by fixing atmospheric N. Consequently, plants had a continuous supply of N, resulting in enhanced growth and an increased yield of grains.…”

Combined Application of Organic and Inorganic Nitrogen and Seed Inoculation with Rhizobacteria (Stenotrophomonas maltophilia FA-9) Improved Productivity, Nitrogen Use Efficiency, and Economic Returns of Pearl Millet

Nitrogen (N) availability and soil microbiota exert significant impacts on plant metabolic systems and yield. Different studies have indicated that yield and nitrogen use efficiency (NUE) of pearl millet (Pennisetum glaucum L.R.Br.) can be improved by the inoculation of N-fixing bacteria. However, the interactive effects of different N sources and bacteria inoculation on growth, productivity, and NUE of pearl millet have been less explored. Therefore, individual and interactive effects of different N sources (organic and inorganic) and bacteria inoculation on growth, productivity, and NUE of pearl millet were investigated in this study. Two different N sources, i.e., organic (farmyard manure) and inorganic (urea) alone or in 50% + 50% combinations (urea + FYM), were used to supply the recommended amount of N. Similarly, seeds were inoculated with two different N-fixing bacteria, i.e., endobacteria (Enterobacter sp. MN17) and rhizobacteria (Stenotrophomonas maltophilia FA-9). Urea + farmyard manure (FYM) and seed inoculation rhizobacteria improved soil attributes, yield-related traits, grain quality, NUE, and net economic returns. Soil porosity was significantly improved by seed inoculation with both bacteria and FYM application. Similarly, seed inoculation with rhizobacteria increased soil organic carbon by 45.45% and 34.88% during the 1st and 2nd year of the study, respectively. Urea + FYM application combined with rhizobacteria seed inoculation improved the number of grains per ear (23.49 and 23.63%), 1000-grain weight (5.76% and 7.85%), grain yield (23.19% and 25.0%), and NUE (33.83 and 48.15%). Similarly, grain quality was significantly improved by seed inoculation with both bacteria. Likewise, urea + FYM combined with rhizobacteria improved nitrogen use efficiency (NUE) by 33.83% and 48.15% in 2020 and 2021, respectively, compared to no N application and no seed inoculation. The highest economic returns (1506.4 and 1506.9 USD) were noted for urea + FYM application combined with rhizobacteria seed inoculation. Therefore, urea + FYM application combined with rhizobacteria (S. maltophilia FA-9) seed inoculation seemed a viable approach to improve grain yield, grain quality, NUE, and net economic returns of pearl millet.

This investigation was carried out at Agricultural Researches Center Al Giza, Egypt, under greenhouse experiments during 2019 and 2020 winter seasons. The study included the effect of three organic fertilization sources: compost, poultry, vermicompost and without organic fertilizer, with mixed inocula (N2 fixers Azotobacter chroococcum (A C), phosphate dissolving bacteria (Bacillus megatherium var. phosphaticum (B M), potassium mobilizers (Bacillus circulans (B C)) and without microbial inoculation on height, weight of plant and spike weight as well as (N, P and K) uptake of barley plant variety Giza 126. This experiment was conducted in pots 3 kg.Obtained results showed that the plant height, plant weight and spike weight as well as (N, P and K) uptake of barley plant were increased significantly by adding the poultry or vermicompost compared to without organic fertilization addition in both seasons. Generally, in most cases, all parameters were increased significantly by microbial inoculation compared to the control treatment (without microbial inoculation) in both seasons. The parameters were improved significantly by adding poultry or vermicompost with mixed inocula (N2 fixers (Azotobacter chroococcum (A C), phosphate dissolving bacteria (Bacillus megatherium var. phosphaticum (B M), potassium mobilizers (Bacillus circulans (B C)) in both seasons.
