“…Excessive use of inorganic fertilizer alone causes an increased yield for some extent but this increased yield will not sustain for a long as continuous application of mineral fertilizers deteriorate soil health and create environmental pollution [3]. In terms of soil fertility and productivity, organic manures are superior to inorganic fertilizers because they improve soil health by improving physical, biological and chemical properties of soil [4][5][6][7][8] which result in higher yield and better-quality crop [9]. Moreover, application of organic amendments not only enhance the crop production but also can ameliorate soil salinity [10][11][12].…”

Aims: Under the intensive agriculture system, it is crucial to maintain the soil fertility for the sustainability of crop production. Therefore, the study was conducted in the experimental field of the Department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to investigate the effect of different manures in combination with synthetic inorganic fertilizers on growth, yield and yield contributing characters of BARI Mistimorich 1 (Capsicum annuum L.), a variety of sweet pepper. Nutrient content of capsicum and soil fertility status were also assessed. Materials and Methods: The field trial was established following a randomized complete block design (RCBD) having four replicates. Treatments of the field trial included T1= 100% recommended dose of chemical fertilizers (RDCF), T2= 10t/ha cowdung (CD) + IPNS based chemical fertilizers (CF), T3=10t/ha poultry manure (PM) + IPNS based chemical fertilizers (CF) and T4= 10t/ha vermicompost (VC) + IPNS based chemical fertilizers (CF). Results: Experimental results reveal that application of organic manures in combination with chemical fertilizers produced significantly higher plant height, plant weight, number of branches per plant, number of flowers per plant, number of fruits per plant, fruit weight, fruit length, fruit diameter, total yield and nutrient content and uptake in sweet pepper. Organic manures (CD, PM and VC) in combination with chemical fertilizers ensured higher nutrient uptake when compared with the sole application of inorganic fertilizers. Among the treatments, vermicompost treated plots gave the higher yield of sweet pepper and improved the post-harvest soil nutrient status. Conclusion: Vermicompost was found to be suitable as substitute of other organic manures for the production of capsicum.

“…This indicates that less power puddling can enhance the positive effects from returned straw, and it may relate to the improved nutrient supply capacity of soil. Previous research also indicated that when the soil's fertility was supplemented and enhanced, rice nutrient uptake and accumulation was notably improved [44][45][46], especially from heading stage to maturity stage, and less power puddling improved nutrient supply and retention capabilities by protecting soil structure [36,47]. Nutrients were released gradually as rice grew, ensuring a continuous nutrient supply for rice to uptake [48][49][50].…”

“…Consequently, soil ammonium nitrogen content was lower when transplanting rice. However, after jointing stage, the protected soil aeration conditions facilitated the decomposition of straw [36,37], leading to a significant increase in soil ammonium nitrogen content from jointing to maturity stages. It can be inferred that less power puddling played a role in adjusting the timing of nutrient release.…”

The rice production system in China is facing challenges, including declining soil fertility and a stagnant rice yield. This study aimed to test whether integrating the return of straw to fields with less power puddling could simultaneously enhance soil fertility and rice yields. Therefore, field experiments were conducted in Heilongjiang Province, a key rice-growing region in China, from 2017 to 2021, using three different planting methods: control group (CK), straw return (SR) and straw return integrated with less power puddling (SR + LP). The results showed that small soil aggregates (particle diameter < 0.25 mm) and soil bulk density were significantly decreased when straw return was integrated with less power puddling. These changes contributed to the preservation of soil structure. Simultaneously, this approach significantly increased soil ammonium nitrogen content from 9.9 to 10.9 mg kg−1, organic matter content from 35.0 to 36.2 g kg−1, available nitrogen content from 140.5 to 147.0 mg kg−1 and available potassium content from 128.6 to 136.8 mg kg−1 at mature stage on average. Consequently, the post-heading stored assimilates accumulation of rice was increased from 6.12 to 6.43 t ha−1, and the nitrogen, phosphorus and potassium accumulation of rice were increased by 7.85 kg ha−1, 1.13 kg ha−1 and 5.68 kg ha−1, respectively. These changes ultimately resulted in a higher 1000 g weight and filled grain rate, providing the foundation for higher yields (an increase from 9.31 t ha−1 to 9.55 t ha−1). Furthermore, this approach also increased the net income for farmers by USD 14 t ha−1. In summary, this study demonstrates that integrating straw return with less power puddling can enhance soil’s nutrient supply and retention capacity. This enhancement may boost the absorption and transportation of nutrients, ultimately establishing the groundwork for higher yields and economic benefits by enhancing the 1000 g weight and filled grain rate. Future research should delve deeper into its applicability across different ecosystems and investigate the yield-increasing mechanisms.

“…The addition of biofertilizers increases the speed of the decomposition of organic matter by a microorganism, and improve soil quality and plant productivity. Organic amendments appear positively to increase the C content and C uptake in the soil [16]. The application of biofertilizers integrated with chemical fertilizers in a sustainable manner can meet the nutritional needs of plants in addition to maintaining soil health and environmental safety [17].…”

The low availability of nutrients is an obstacle to increasing rice productivity in rainfed rice fields. The application of a combination of biofertilizers and inorganic fertilizers was known to increase the efficiency of using inorganic fertilizers. This study aims to determine the effect of biofertilizers on the growth and yield of rice plants in a rainfed rice field. The study was conducted on rainfed rice fields in Banyusri Village, Wonosegoro District, Boyolali Regency from September to December 2013. A total of 6 biofertilizer products were used in this study, namely PR, RC, ST, AGR, BV and GLK. The rice variety used was Situ Patenggang. The study used a randomized block design with 9 treatments and each treatment was repeated 4 times. The nine treatments were: fertilization according to the recommendations of dry soil test device (P1); ½ dose of P1 (P2); P2 + manure (P3); P2 + PR (P4); P2 + RC (P5); P2 + ST (P6); P2+AGR (P7); P2+BV (P8); P2+GLK (P9). Planting using a 2:1 jajar legowo system with a spacing of 20 x 10 x 40 cm was carried out by direct planting of 4-5 seeds per hole. Biofertilizer application is carried out according to the instructions of each product. Parameters observed included: soil chemical status (N, P, K, C-organic, pH, CEC) before the study; plant growth (plant height, number of tillers and number of productive tillers); yield (weight of harvested dry grain and dry milled); and a simple farming analysis was carried out. The results showed that all combinations of biofertilizers with ½ recommended dose were effective in increasing rice yields but they could not match the yield of rice fertilized according to the recommended dose. The combination of fertilization using GLK biofertilizer showed the highest yield compared to other biofertilizers with an advantage of 48.05% compared to ½ recommended dose of fertilization.
