Growth and Yield Responses of Sweet Pepper (Capsicum annum L.) to Organic and NPK Mineral Fertilization under Plastic Houses Conditions at Arid Regions

Abstract

Two greenhouse experiments were conducted during 2014/ 2015 and 2015/2016 seasons in the Experimental Station Farm, Faculty of Agriculture and Natural Resources, Aswan University, Egypt on a sandy textured soil under unheated plastic houses. The target fertilization program seeks to achieve the best combination of various organic and NPK mineral fertilization that lead to the highest yield and quality of produced sweet pepper plant ''Lama Star F 1 hybrid'' especially during the winter season. Therefore, 12 treatments were arranged in a Split plot layout in complete randomize block design with three replicates. Chicken manure at the rates of (10, 15 and 20m 3 /fed.) were randomly arranged in the main plots, while NPK mineral fertilization at rates of (0:0:0, 50:30:50, 100:40:80, and 150:50:110 Kg N:P 2 O 5 :K 2 O/fed., respectively, were randomly distributed in the subplots. The obtained results demonstrated that the treatment combination of chicken manure at 20 m 3 / fed. Plus either 150:50:110 or 100:40:80 Kg. NPK/fed. brought about the highest significant mean values of most studied characters as vegetative growth characters (i.e. plant height, number of leaves/plant, the number of branches /plant and plant fresh weight); yield characters {i.e. No. fruits /plant, average fruit weight (g), early yield/m 2 (kg) and total yield/m 2 (kg)}; fruit quality (i.e. TSS %,vitamin C, and non-reducing fruit sugars); chemical analysis characters (viz,a, b and total chlorophyll and N, P, K contents in leaves and fruits ) during both seasons of the study as compared to the other treatments. Based upon, the reported results, it is possible to conclude that, the combination among 20 m 3 /fed. of chicken manure plus either 150:50:110 or 100:40:80 Kg. NPK/fed. considered as the optimal combination treatment whereas it gave the highest mean values of vegetative growth characters, yield and its components and fruit quality of pepper plants grown under plastic houses conditions at Aswan governorate.

Effect of nano-chitosan encapsulated spermine on growth, productivity and bioactive compounds of chili pepper (Capsicum annuum L.) under salinity stress

“…The distance between plants was 50 cm. The organic fertilizer (48 m 3 /ha) was added at soil preparation, whereas the chemical fertilizers were added in three equal doses as recommended (NPK, 238:95:190 kg/ha), the first dose was added at soil preparation, the second was added at 30 days after transplanting and the third at the beginning of flowering stage [24]. Plants were irrigated from the well with saline water __________________________________________________________________________________________________________________ ________________________________________________ Egypt.…”

The Application of Chicken Manure and NPK Fertilizer on Growth and Yield of Shallot Plant in Tidal Land of Banyuasin Regency

“…This was in line with the highest specific leaf area in MP3 indicating a low shoot weight divided by the root portion so that a low shoot-root ratio was obtained. A report by Alkharpotly (2018) on Capsicum annum L. showed that the combination of 20 tons organic chicken manure per ha combined with inorganic fertilizer was the optimal combination treatment resulting in the best average value of vegetative growth characters. The results of another study showed that the application of various organic fertilizers without a combination of inorganic fertilizers did not give a positive response to the growth of shallots (Suwandi et al, 2015;Arifin & Mujoko, 2019).…”
