ABSTRACT " RESPONSE OF SWEET PEPPER CROP TO ORGANIC AND BIOFERTILIZER APPLICATION " Two field experiments were carried out on sweet pepper Capsicum annuum L. cv. California Wonder at the Experimental Farm of the Faculty of Agriculture, Moshtohor, during the summer seasons of 2000 and 2001. The first experiment dealt with the effect of inoculating sweet pepper seeds and transplant roots with a single or mixed biofertilizer; Nitrobin and/or Phosphorin in addition to the 0, 25, 50, 75% of the required N and/or P fertilizer level. Results showed that the most favorable treatment was that inoculated with Nitrobin + Phosphorin and fertilized with 75% of the required N and P level; 60 kg N + 48 kg P 2 O 5 + 96 kg K 2 O, which gave the highest growth, yield and fruit quality of sweet pepper in both seasons. The second experiment studied the response of sweet pepper plants to 4-organic fertilizer sources (Biogas, FYM, Agrolig and Chicken manure) within 4-methods of Napplication. Results showed that plants which received 30 kg N as Biogas + 30 kg N in its mineral form + 64 kg P 2 O 5 + 96 kg K 2 O , gave the best growth, yield and fruit quality as a general trend in both seasons. 1.

University of Thi-Qar Journal of agricultural research, 2021
The experiment was carried out at the Agricultural Research Station of the College of Agriculture and the Marshlands / University of Thi-Qar, located in Al-Mustufawia for the agricultural season (2019-2020). The study was the effect of cultivar and organic and mineral fertilization on the qualitative and quantitative characteristics of cucumber crops grown in greenhouses, and applied according to the factorial experiments inside the split plots, using the complete randomized sectors with three replications. The factors of research were: two cultivars (Datis and Sakata) occupied the main plots, three levels of organic fertilization occupied the secondary plots which included control treatment O 1 , cow manure O 2 (2.457 tons of greenhouse-1) and poultry manure O 3 (3.713 tons of greenhouse-1) and the third factor was four levels of mineral fertilization (NPK) including control treatment M 1 , M 2 (2.250 kg. dunam-1), M 3 (3.350 kg. dunam-1), and M 4 (4.450 kg. dunam-1) which occupied the sub-plots. The results showed that Datis cultivar significantly outperformed Sakata cultivar in yield per plant, total yield, leaf content of nitrogen and phosphorus, and fruit content of carbohydrates, reaching (1.402 kg. plant-1 , 24.24 tons .greenhoues-1 , 2.2517%, 0.4069%, 1.2876%) respectively. On the other hand, the treatment of organic fertilizer O 3 recorded a significant effect in the following crop traits such as leaf area, total yield, leaf content of nitrogen and phosphorus, and fruit content of carbohydrate, reaching (178.0 cm 2 , 24.36 tons. greenhouse-1 , 2.5017%, 0.4608%, 1.3561%). Respectively compared to other treatments, total yield, leaf content of nitrogen and phosphorus, reaching (180.1 cm 2 , 25.88 t. greenhoues-1 , and 2.3478%, and 0.4561%) to other treatments. The treatment M 2 significantly outperformed in yield per plant (1.682) kg. plant-1 and treatment M 3 significantly exceeded the fruit's carbohydrate content, reaching (1.2930%). All the combinations among this study's treatments were compared to meet their significant effecting on all traits.
Growth, Yield and Fruit Quality of Sweet Pepper Plants as Affected by Some BioOrganic and Mineral
Two field trials were conducted at the Experimental Farm of the Faculty of Agriculture, Tanta University, Egypt, during the summer growing seasons of 2011 and 2012, to evaluate the effect of some bio organic and mineral fertilizers (compost at 10, 15 and 20 ton/fed., Easternabiofert at 50, 100 and 150 kg/fed. plus recommended dose of organic manure, the mixture of bio-fertilizers (Phosphorein, Potassiumage and Rhizobacterin) combined with 75% of the recommended dose of mineral fertilizers and farmyard manure and 100 % of recommended dose of mineral fertilizers plus farmyard manure) on growth, flowering, yield and fruit quality of sweet pepper plants cv. California Wonder. The obtained results indicated that, the application of the three treatments; (the first was recommended dose of NPK plus farmyard manure, the second was 75% recommended dose plus Phosphorein, Potassiumage and Rhizobacterin the third treatment was Easternabiofert at 150 Kg/fed plus recommended dose of organic manure,) followed by compost at 20 ton/fed., significantly increased plant height, number of branches per plant, number of leaves per plant, fresh and dry weight of whole plant, photosynthetic pigments i.e. chlorophyll a, b and carotenoids, Endogenous phytohormones i.e. auxins, gibberellins and cytokinins, fruit weight, number of fruits per plant, dry weight of fruit and early and total fruit yield. Also, significant effects were obtained for N% and P% in the leaves as well as Vitamin C, N % and P % in the fruits in both seasons. There were no significant differences between these treatments and the complete recommended dose of NPK mineral fertilizers in this concern. Different Bio organic treatments resulted in the lowest values of nitrate in fruits, in the two growing seasons. The application of 75% recommended dose of NPK and organic manure plus the mixture of bio-fertilizers (phosphorein, potassiumage and rhizobacterin) or Easternabiofert at 150 Kg/fed plus recommended dose of organic manure can be used in sweet pepper production without reducing the productivity and quality. These bio organic fertilizers treatments will reduce the cost of chemical fertilizers, avoid the risk of nitrate accumulation in the edible portions and decrease the pollution of the environment. Also, applying the compost at 20 ton/fed. leads to lower productivity compared to the full dose of mineral fertilizers, but the yield will be higher in price, achieving more profit for producers.
Understanding the relations and interactions between ecosystem components and plants is crucial for sustainable production of medicinal plants. To study the effect of simultaneous application of organic and biological fertilizers on yield and yield components of zucchini squash, split plot arrangement of factors based on randomized complete block design with three replications were used during 2009-2010 growing season. The mainplot factors were the type of organic fertilizers, including: (1) cow manure; (2) sheep manure; (3) chicken manure; (4) vermicompost; and (5) control. The subplot factors were the biofertilizes (Nitragin, containing Azotobacter sp., Azospirillum sp. and Pseudomonas sp.) utilization. The results showed the positive but non-significant effect of organic and biological fertilizers on yield and yield components of zucchini squash. Amongst the organic fertilizers, cow and chicken manure, have superiority compared to others. The highest seed oil and protein percent was obtained with application of chicken manure, however there was no significant difference between treatments in seed oil percent. The positive effect of organic and biological fertilizers on seed yield was higher than fruit yield. At a glance, application of cow manure solely was better than its application with nitragin. Nitragin application has no significant effect on some traits when utilized with sheep manure and vermicompost.
Growth and yield of bell pepper as influenced by combination of poultry manure and NPK fertilizer
Technology in Horticulture, 2024
A field experiment was carried out to assess the growth and yield of bell pepper to different combination ratios of Poultry Manure (PM) and NPK 15:15:15. The experiment was carried out at a research farm of the Department of Agronomy, University of Ibadan, Nigeria. The treatments, consisting of Control (no fertilizer), 100% NPK, 50% NPK + 50% PM, 33% NPK + 67% PM, 67% NPK + 33% PM and 100% PM were laid out in a randomized complete block design (RCBD) with four replications. Five plants from the same treatment were randomly sampled out of 12 plants per bed and tagged for data collection on growth parameters at 3, 4, 5 and 6 weeks after transplanting as well as number of fruits, fruit length and fruit yield. Data collected were subjected to analysis of variance (ANOVA) and significant means separated using Duncan Multiple Range Test (DMRT) at p < 0.05. Results from this study revealed that plants with application of 33% NPK + 67% PM were significantly (p < 0.05) taller and had more leaves and branches than other treatments and control. Likewise, plants which received 33% NPK + 67% PM treatment had significantly higher fruit yield than control and other treatments. It can therefore be concluded that a high level of poultry manure in combination with lower level of NPK (33% NPK + 67% PM) had the best performance in terms of growth and fruit yield of bell pepper and is therefore recommended.

BIOINFOLET - A Quarterly Journal of Life Sciences, 2009
during Rabi season of 2014-15 to study the effect of organic manures and bio-fertilizers on growth, yield and quality traits of tomato cv. Roma. The seedlings were transplanted in last week of October with a spacing 60cm x 45cm. The experiment was laid out in Randomized Block Design with twelve treatments replicated thrice. Result indicated that the maximum height of the plant (21.95, 33.91 and 45.15cm) was recorded at 30, 60 and 90 DAT with 50% RDF+ 50% VC+ PSB application followed by 50% RDF+ 50% VC+ Azosporillum and minimum in control. The number of branches (4.13, 10.09 and 16.03) was recorded at 30, 60 and 90 DAT with the application of 50% RDF+ 50% VC+ Azosporillum, followed by 50% RDF+ 50% VC+PSB and minimum in control. The number of days taken by plants for flowering was less under control (41.52). The maximum number of flowers, flower clusters and fruits/plant were 31.93, 9.09 and 18.00 respectively in 50% RDF+ 50% VC+ Azosporillum. Similarly maximum fruit weight (70.94 gm) and fruit diameter (7.06 cm) were also noticed with the application of 50% RDF+50% VC+ Azosporillum which is significantly superior over control. Same trend was also noticed in yield per plant (0.991 kg), per plot (15.87 kg) and per ha (73.33q) in the same treatment. The maximum titrable acidity 0.72 was in control among fruits of different treatments while minimum titrable acidity (0.56) was found in fruits of treatment received 50% RDF+ 50% FYM+ Azosporillum. The maximum TSS (5.400B) obtained from the fruits given 100% Vermicompost and minimum in control (3.650Brix). Highest vitamin C of fruits has been recorded in the 50% RDF+ 50% VC+ Azosporillum (23.90%) as compared to the control (21.71%).
