“…Various reports have demonstrated a significant increment in the vegetative growth traits when investigating the effect of organic and biofertilizers on the growth and development of different crops [ 23 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ]. In the present study, the results revealed that treatments T4 (rock phosphate (RP) + strain HM3) indicated the highest and most positive significant values for plant height, number of leaves per plant, and root length ( Table 1 ).…”

The genus Streptomyces is the most abundant and essential microbes in the soil microbial community. Streptomyces are familiar and have great potential to produce a large variety of bioactive compounds. This genus considers an efficient biofertilizer based on its plant growth-promoting activities. Based on their ability to produce a wide varieties of bioactive molecules, the present study aimed to explore the potential plant growth promotion of four Streptomyces strains and their role in enhancing cucumber growth and yield under greenhouse conditions. Streptomyces sp. strain HM2, Streptomyces thinghirensis strain HM3, Streptomyces sp. strain HM8, and Streptomyces tricolor strain HM10 were chosen for the current study. Plant growth-promoting (PGP) features, i.e., indole acetic acid (IAA) production, siderophore excretion, and solubilizing phosphate, were evaluated in vitro. All four strains produced IAA, siderophore, and immobilized inorganic phosphate. Following 4 days of incubation at 30 °C, strains HM2, HM3, HM8, and HM10 produced copious amounts of IAA (18, 22, 62, and 146 µg/mL, respectively) and siderophores (42.59, 40.01, 16.84, 64.14% SU, respectively). At the same time, P solubilization efficacy scored 64.3%, 84.4%, 57.2%, and 81.6% with the same frequency. During in planta evaluation, selected Streptomyces strains combined with rock phosphate were assessed as biofertilizers on the growth and yield of cucumber plants. Under all treatments, positive and significant differences in studied traits were manifested except dry stem matter (SDM), net assimilation rate (NAR), relative growth rate (RGR), and fruit firmness (FF). Treatment T4 (rock phosphate + strain HM3) followed by T5 (rock phosphate + strain HM8) revealed the best results for plant height (PH), number of leaves per plant (NLPP), root length (RL), number of fruits per plant (NFPP), fruit length (FL), fruit diameter (FD), fruit fresh weight per plant (FFWPP), soil P (SP) after 21 DAT, and soil P at the end of the experiment. Notably, T6 (rock phosphate + strain HM10) caused a considerable increase in leaf area (LA). Plant growth-promoting bacteria enhance plant growth and yield through phosphorus solubilizing, improve nutrient availability, produce phytohormones, and support plant growth under abiotic stress. These features are important for sustainable agriculture and reducing environmental pollution with chemical fertilizers and pesticides.

“…The evidence from West Bengal in India [2], northeast of China [3] and Johor in Malaysia [4] have shown that excessive use of chemical fertilizers is one of the main reasons for the decline in cultivated land quality, and promoting fertilization technology is an effective way to achieve chemical fertilizer reduction. The fertilizer reduction technologies refer to those technologies aiming to reduce the use of chemical fertilizers (ARFTs), mainly including farmyard manure, organic fertilizer, and formulated fertilization by soil testing [5].…”

This article examines the impact of the stability of the management rights of transferred land (TLMR) on the adoption of technologies aiming to reduce the use of chemical fertilizers (ARFTs) based on the survey data of large-scale grain growing households in Anhui, China. Using the IV-Probit model, the present paper defines the stability of TLMR and the results estimated by IV-Probit model shows that a one-year extension of land lease period can increase the probability of using organic fertilizer and soil-testing formula fertilizer by 3.16% and 4.92%, respectively, while contract breaching in the lease period can reduce the probability of using organic fertilizer and soil-testing formula fertilizer by 46.9% and 51.38%, respectively. However, the land-lease period and land transfer contract breaching in the lease period have no significant effect on the use of farmyard manure by large-scale grain growing households. The main conclusion is that improving the stability of TLMR is conducive to prompting large-scale grain growing households to adopt ARFTs, especially the adoption of organic fertilizer and soil-testing formula fertilizer. The government should improve the stability of TLMR by standardizing the form and content associated with land transfer contracts and setting the minimum land-lease term.

“…Fertilizers play an essential role in enhancing agricultural productivity, but the current excessive application of chemical fertilizers has caused a series of environmental pollution and eutrophication problems [ 20 , 21 , 22 , 23 ]. Under the premise of guaranteeing national food security and agricultural income of farmers, how to reduce the application of chemical fertilizers has become an important issue [ 24 ].…”
