Effect of Organic Manures and Mineral Fertilizers on Soil Properties and Yield of Sweet Pepper (Capsicum annuum L.)

Abstract

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.

Differential responses of liquid and solid organic manures on the performance of capsicum (Capsicum annuum L.) under North Western Himalayan region

“…As poultry manure contain higher nitrogen and phosphorous compared to other bulky manures, which means that poultry manure is sufficient to increase the avalability of phosphorous. These results are in accordance with Sharma et al (2020) [29] and Salma et al (2022) [28] . Treatment T2 (Vermicompost 50% + Farm Yard Manure 50%) shows better avalabitily (233.20 kg/ha) of potassium in the soil after harvest, followed by treatment T3 (Poultry manure 50% + Farm Yard Manure 50%).…”

“…By supporting cell division and enlargement, ensuring efficient photosynthesis and nutrient transport, potassium plays an important role in optimizing the growth conditions necessary for producing healthier fruits. Similar results were reported by Jamir et al (2017) [16] , Altaf et al (2019) [2] , Reddy et al (2017) [26] , and Salma et al (2020) [28] . Similarly, Treatment T2 (Vermicompost 50% + Farm Yard Manure 50%) resulted inhigher yield per plant (1.33 kg), yield per plot(11.98 kg) and yield per hectare (269.48 q/ha) which was followed by treatment T3 (Poultry Manure 50% + Farm Yard Manure 50%) i.e.…”

Assessment of Pistachio Shell-Based Biochar Application in the Sustainable Amendment of Soil and Its Performance in Enhancing Bell Pepper (Capsicum annuum L.) Growth

“…Soil preparation included flood irrigation followed by fluffing and weeding. In addition, the soil was fertilized with horse manure at a rate of 10,000 kg/ha [45]. Subsequently, the beds were prepared for transplanting the final cultivation.…”

“…Considering the findings of other researchers regarding the impact of various fertilizers on pepper crops, it is noteworthy to mention the study by Salma et al [45]. In their research, they examined the effects of cow manure, poultry manure, and vermicompost, in combination with inorganic fertilizers, on the growth and yield of C. annuum.…”
