“…Yadav et al (2023d) emphasized the significant contribution of soil biota in improving soil quality, supporting plant health, and enhancing soil resilience, highlighting its indispensable role. Rhizobacteria that promote plant development do so by mobilizing nutrients, making phytohormones, and fixing nitrogen in a non-symbiotic way (Jalal et al, 2022). Additionally, the presence of beneficial microorganisms plays a critical role in maintaining soil fertility, enhancing plant resilience, and promoting overall crop health, as highlighted by Yadav et al (2023e).…”

A field study was conducted at a farmer’s field in Ratuwamai, Morang, from February 2023 to June 2023 to assess the impact of various bio-fertilizer sources on the growth and yield characteristics of rice. The experiment followed a randomized complete block design (RCBD) with three replications and seven treatments. The treatments included: T1: Recommended NPK dose (100:30:30 kg/ha), T2: Farmyard manure (FYM) (12 t/ha), T3: Goat manure (8 t/ha), T4: Mycorrhiza (11.25 kg/ha), T5: Organic manure (11.25 kg/ha), T6: Mustard seed cake (3.75 t/ha), and T7: Control (no fertilizer). Our investigation explored the significant effects of these treatments on the growth and yield-contributing attributes of the Chaite-4 rice variety. Results indicated that T1 (7021.47 kg/ha) and T2 (6681.70 kg/ha) exhibited the highest grain yield, followed by T3 (5128.35 kg/ha), T2 (4482.78 kg/ha), T5 (4335.79 kg/ha), T4 (4253.80 kg/ha), with T7 showing the lowest yield (3971.64 kg/ha). The maximum straw yield was observed in T1 (11037.50 kg/ha) and T6 (10644.16 kg/ha), while the control (T7) had the lowest (7681.66 kg/ha). Additionally, parameters such as plant height, number of tillers per hill, effective tillers per hill, panicle length, panicle weight, 1000-grain weight, grains per panicle, and SPAD value were highest in T1 and T6, and lowest in T7. Furthermore, the biofertilizers with the greatest benefit-to-cost ratios were organic manure and mycorrhiza (2.0 and 1.9, respectively), while goat manure showed an average ratio (1.6), indicating their cost-effectiveness. These findings demonstrate that the application of these biofertilizers enhances rice crop development and output, leading to substantial returns on investment.

IntroductionChrysanthemum morifolium Ramat. is a perennial herb in the Compositae family, often employed in traditional Chinese medicine due to its medicinal value. The planting of C. morifolium faces the challenges of continuous cropping, and intercropping is able to somewhat overcome the obstacles of continuous cropping.MethodsIn our study, we designed two different C. morifolium-maize intercropping patterns, including C. morifolium-maize narrow-wide row planting (IS) and C. morifolium-maize middle row planting (IM). Compared with monoculture, the agronomic traits, yield, active ingredients, soil physicochemical properties, soil enzyme activities, and rhizosphere soil microbial communities of C. morifolium and maize were measured under the two C. morifolium-maize intercropping patterns.ResultsThe findings indicated that (1) Intercropping elevated the agronomic traits, yield, and active ingredients of C. morifolium, especially in C. morifolium-maize narrow-wide row planting pattern, which indicating that interspecific distance played an important role in intercropping system; (2) Intercropping enhanced soil physicochemical properties and enzyme activities of C. morifolium and maize; (3) Intercropping altered rhizosphere soil microbial communities of C. morifolium and maize, making microbial interrelationships more complex. (4) Intercropping could recruit a large number of beneficial microorganisms enrich in the soil, including Bacillus, Sphingomonas, Burkholderia-Caballeronia-Paraburkholderia, Chaetomium, and Ceratorhiza, which may increase the content of AN, NN, AvK, ExCa, AvCu, AvZn and other nutrients in soil and promoted the growth and quality of C. morifolium.DiscussionIn summary, intercropping with maize could promote the accumulation of beneficial microorganisms in the soil, thus improving the overall growing environment, and finally realizing the growth and improvement of C. morifolium.
