Impact of cultivar and irrigation on yield, leaf surface temperature and SPAD readings of chili pepper

Paprika is an extremely popular and widespread plant species in Hungary. Chili peppers belongs to paprika and it can be consumed fresh or processed. The production of peppers began with the cultivation and control of some parameters for good results of paprika production. The aim of this article is to compare the water supply of four chili pepper hybrids ("Habanero", "Hetényi Parázs", "Unikal" and "Unijol") by means of investigation on open field and to examine how different temperatures and water stress factors influence the yield of chili peppers. The experiment area consisted of four different hybrids in three different irrigation treatments (control, deficit- and regular irrigation). The chlorophyll content was estimated with SPAD and the leaf surface temperature with Raytek MX4 TD. Our research concluded that deficit irrigation produced the highest yields for all cultivars and the lowest yields for the highest water supply.

Effect of Controlled-Release Coated Fertilizer on Yield and Nitrogen Use Efficiency in a Red Pepper Cultivated Field

Improving the nitrogen use efficiency (NUE) of crops is a technology that improves crop productivity and prevent environmental pollution simultaneously. A way to improve NUE is to develop and use a controlled release fertilizer. We developed a controlled release fertilizer in terms of controlled-release coated fertilizer for rhizosphere application (CRFR) which is a mineral fertilizer applying just under the plant root zone. In order to test effect of the developed CRFR on crop yield and NUE, field experiments were conducted with six levels of N (N 0, N 190, CRFR-N 16, CRFR-N 22, CRFR-N 27, and CRFR-N 33 kg ha-1) at the experimental station of Gyeonggi-do Agricultural Research & Extension Services (GARES) for two years (2017 to 2018). The fruit yield and NUE of red pepper were obtained using agronomic measurements. To determine optimum N rate of CRFR we applied linear-plateau model. Results showed that the yield was not significantly different between the two levels of CRFRs (N 22 and 27) and N 190 in 2017. Similarly, the yield was not different between the three levels of CRFRs (N 22 and 27) and N 190 in 2018 although almost six times as much N rate was applied in the N 190. Meanwhile, NUEs in the CRFRs were ranged from 69.8 to 88.5% which were much higher than the N 190 treatment (14.8%). Since CRFRs showed no different yields as compared to N 190, we analyzed the optimum rate of CRFR using the linear plateau model and CRFR applied at 23.1 kg N ha-1 was optimal for the yield. Our results suggest that CRFR was able to significantly increase crop productivity while reduce environmental pollution because of remarkably high NUE. Since CRFRs showed no different yields as compared to N 190 (recommended N dose from RDA), we analyzed the optimum rate of CRFR using the linear plateau model, and CRFR applied at 23.1 kg N ha-1 was optimal for the yield.

Activity of the Novel Fungicide Mefentrifluconazole Against Colletotrichum scovillei.

The prevalence and destructiveness of anthracnose, caused by Colletotrichum scovillei, in pepper production regions seriously affects pepper yield and quality. Mefentrifluconazole, the first of the isopropanol-azole subgroup of triazole fungicides, was introduced for the control of pepper anthracnose. However, the growth characteristics of pepper fruit and rapid spread of anthracnose suggest that the fungicide application method must be optimized to enhance fungicide efficacy. The sensitivity of C. scovillei to mefentrifluconazole was determined by mycelial growth and germ tube elongation assays using 157 single-spore isolates with mean 50% effective concentration values of 0.462 ± 0.138 and 0.359 ± 0.263 mg/liter, respectively. The in vivo data also showed that mefentrifluconazole had favorable protective and curative effects against pepper anthracnose. Mefentrifluconazole significantly affected C. scovillei infection on pepper by reducing appressorium formation and sporulation, shriveling spores and germ tubes, and causing the abnormal development of appressoria and conidiophores. Mefentrifluconazole could move acropetally, horizontally, and basipetally in pepper plants. Compared with a knapsack sprayer, mefentrifluconazole applied by mist sprayer exhibited significantly better activity against pepper anthracnose. Additionally, as the spray volume increased from 45 to 150 liters/ha, the control efficacy of mefentrifluconazole first increased and then tended to be steady, with an optimal spray volume of 90 liters/ha. The difference in disease control efficacy was related to the deposition and droplet distribution of mefentrifluconazole on the pepper fruit. These results provide scientific guidance for the application of mefentrifluconazole in pepper fields and improved fungicide utilization.

RESPONSE OF CAYENNE PEPPER TO GIVING BAMBOO SHOOTS LIQUID ORGANIC FERTILIZER

Cayenne pepper is a vegetable plant that has great potential to be developed in Indonesia because it can meet the needs of households, domestic industries, exports, and raw materials in the pharmaceutical industry. One way to increase the yield of cayenne pepper is by giving liquid organic fertilizer (POC) for bamboo shoots. This study aims to determine the response of cayenne pepper toward the application of POC and gets the best POC concentration to support the growth and production of cayenne pepper. This study used a randomized block design with treatment in the form of POC concentrations consisting of 5 levels (0; 25 ml / L water; 50 ml / L water; 75 ml / L water; 100 ml / L water). Each treatment consisted of 4 replications so that there were 20 experimental units. The results show that the application of POC had a very significant effect on the number of flowers, fresh weight of fruit, and growth rate of cayenne pepper with the best treatment was 75 ml / L of water.

Effect of Organic Fertilization and Amino Acids on Growth, Chemical Composition and Capsaicin Content of Hot Pepper (Capsicum annum L var. Minimum) Plant

This investigation was conducted in a private farm, Samannoud district, El-Gharbia Governorate, Egypt, during two successive seasons of 2017 and 2018 to study the effect of organic fertilizers and foliar spray of amino acid on vegetative growth, fruit yield, chemical composition and capsaicin content of hot pepper (Capsicum annum L var. Minimum) plant. The experiment included 13 treatments obtained from cattle manure at rates of 60 and 30 N-units per fed. combined with amino acid at 0, 100 and 200 ppm as well as chicken fertilizer at rates of 60 and 30 N-units per fed combined with amino acid at 0, 100 and 200 ppm, besides the treatment of NPK at recommended dose as a control. A complete randomized block design with three replicates was adopted.
 The obtained results showed that, the highest values from vegetative growth parameters, fruit yield, chemicals composition and capsaicin content were obtained from plants treated with cattle manure full dose + 200 ppm amino acids , followed by plants treated with chicken manure full dose + 200 ppm amino acids compared with all treatments except plant height, the highest value was obtained from plants treated with NPK (control) in the two seasons. Amino acid had a great effect when added with organic fertilization, whether cattle manure or chicken fertilizer at a concentration of 100 or 200 ppm. Based on the previous results, it could be recommend that spraying amino acids (glycine and glutamine) at the rate of 200 ppm along with organic fertilizers at the rate of 60 nitrogen units per feddan get the highest fruits yield, Vitamin C and capsaicin of hot pepper.

Production and photosynthetic pigments of bell peppers all big (Capsicum annuum L.) subjected to fertilization with biochar and nitrogen

The Northeastern semi-arid region provides favorable conditions for bell pepper cultivation, but most often the low availability of soil nutrients to plants constitutes a limiting factor to production. In this context, the present study aimed to evaluate the production and photosynthetic pigments of bell pepper subjected to increasing levels of fertilization with biochar and nitrogen. The experiment was conducted in pots (Citropote®) under greenhouse conditions. Treatments were arranged in a completely randomized design, in 4 x 4 factorial scheme, relative to four doses of biochar (0; 7; 14 and 21 m3 ha-1) and four doses of nitrogen (0; 40; 80 and 120 kg ha-1), with three replicates. Fertilization with 70 kg ha-1 of nitrogen and 14 m3 ha-1 of biochar promotes highest yield of bell pepper in terms of number of fruits and fruit fresh weight per plant. The highest contents of photosynthetic pigments were obtained in plants fertilized with 70 kg ha-1 of nitrogen associated with 10 m3 ha-1 of biochar. Biochar doses above 15.54 m3 ha-1 negatively affect the longitudinal diameter of bell pepper fruits. The recommendation of 120 kg ha-1 of nitrogen and 20 m3 ha-1 of biochar reduces bell pepper production and photosynthetic pigments.

Conductividad eléctrica de la solución nutritiva efecto en el rendimiento y la calidad nutracéutica de pimiento morrón

La concentración de ionica de la solución nutritiva en sistemas hidroponicos influye en el rendimiento y la calidad de los frutos cosechados. Bajo esta perspectiva el objetivo de este estudio fue determinar el efecto de la conductividad eléctrica (CE) de la solución nutritiva (SN) sobre el rendimiento y contenido de compuestos bioactivos en frutos de pimiento morrón. Bajo un diseño experimental completamente al azar con diez repeticiones, plantas de pimiento fueron irrigadas con una SN a diferente CE (1, 2, 3.2 y 4 dS m-1), se determinó el rendimiento y en frutos se cuantificaron los compuestos biactivos. Los resultados indican que una conductividad eléctrica de tres o superior mejora la calidad nutracéutica, pero disminuye el rendimiento de pimiento morrón. El manejo agronómico de la CE en la SN es una alternativa para incrementar la calidad nutracéutica y la capacidad antioxidante de los frutos de pimiento morrón desarrollado en condiciones hidroponicas.

Influence of Poultry Manure on Growth and Fruit Yield of Selected Pepper Species and Their Qualities after Storage in Various Structures

The production of pepper is low due to decrease in fertility of soil and inadequate storage structures. The study was aimed at evaluating the growth, yield and storage qualities of selected pepper varieties as influenced by poultry manure and storage structures in Ibadan, Nigeria. A field experiment was carried out at Department of Agronomy, University of Ibadan between November, 2017 and April, 2018 growing season. Two varieties of pepper (Capsicum annum and Capsicum frutescens) were used, with four treatments consisting of different rates of poultry manure. Controls of 0 g of poultry manure (T1), 12.5 g (T2), 25 g (T3) and 37.5 g (T4) were laid out in a complete randomised design and replicated four times. Storage experiment was carried out in the Department and at Nigeria Stored Products Research Institute (NSPRI), Ibadan in June, 2018. The storage experiment comprised of four treatments with ambient condition (open shelf), wet basket, Evaporative Coolant Structure (ECS/Pot-in-pot), and plastic crates used as storage structures, laid out in a completely randomised design and replicated three times. The physical parameters obtained in days in storage (DIS) included weight loss (%), firmness, freshness, among others. Data observed were subjected to analysis of variance (ANOVA) and means separated using least significant difference (LSD) at p>0.05. The result obtained showed that pepper growth was enhanced using Capsicum frutescens under 25 g poultry manure application rate which resulted to superior pepper yield. The combination of pot-in-pot with sawdust as storage structures enhanced the storage qualities of pepper fruits within the two weeks of storage. Although, the different manure treatments had no significant effect on the postharvest quality of pepper, the ECS can be effectively used in the storage of pepper fruits in order to improve postharvest quality, extend shelf life and enhance affordability of the commodity at all seasons.

Effect of Water Stress on Crop Yield and Water Productivity of Drip-irrigated Pepper (Capsicum Spp.) in Southwest Nigeria

This research presents the effects of water stress on crop yield and water productivity of two local varieties of pepper (Capsicum spp.) under various drip irrigation regimes in Southwest Nigeria.
 Study Design: The study was conducted during the 2018 and 2019 cropping seasons at the Teaching and Research Farm of Agricultural and Bio-Environmental Engineering of Federal Polytechnic, Ilaro, Nigeria.
 The experiment was a 2 x 4 factorial experiments arranged in a randomized complete block design (RCBD) with two varieties of pepper (Capsicum chinense and Capsicum frutescens) and four drip irrigation regimes: 100%, 75%, 50% and 25% of actual crop evapotranspiration (ET100, 75, 50, 25) and replicated four times. The experiment was repeated in the second year late season. Water was applied from 3 weeks after transplanting (WAT) after which growth parameters, crop water productivity and crop yield were monitored and subjected to statistical analyses.
 The water productivity, crop yield and other crop growth parameters such as plant height, number of leaves, fruit length and weight were higher during the two seasons for the two pepper varieties under ET100 and ET75 irrigation regimes compared with ET50 and ET25 respectively. A significant difference (p<0.05) was observed in the growth parameters in all the treatments. However, there was no significant difference (p>0.05) in the water productivity components for ET100 and ET75 irrigation regimes. The best water productivity was observed for the ET75 drip irrigation regime.
 Therefore, the ET75 regime was recommended for the two pepper varieties to ensure sustainable cultivation and production of the two varieties in the study area.

Yield and morphological attributes of bell pepper fruits under biological fertilizers and application times

ABSTRACT Bell pepper (Capsicum annuum) is one of the most consumed vegetables around the world. Balanced fertilization is essential for growing this vegetable. The objective of this study was to evaluate the yield and morphological attributes of bell pepper under doses and times of application of biological fertilizers. Two experiments were carried out with applications of biological fertilizers prepared from manure and enriched organic compounds with cattle manure and sheep manure. The experimental design was a randomized complete block design, in a 4 x 3 + 1 factorial scheme, with three replications, referring to doses of biological fertilizers (100, 200, 300 and 400 L ha-1), times of application (0, 30 and 60 days after transplanting - DAT) and control. The evaluated variables were: total fruit weight (TFW), number of commercial fruits (NCF), number of non-commercial fruits (NNCF), fruit weight (FW), fruit diameter (FD), fruit length (FL), resistance of fruit peel (RFP), number of flower buds (NFB) and productivity (P). Biological fertilizers caused positive effects on TFW, NCF, FW and P of bell pepper. The application of cattle manure at 60 DAT and sheep manure at 30 DAT promoted a larger fruit diameter. The FW, FL and RFP were influenced by the doses and times of application of biological fertilizers. The application of biofertilizers is efficient in the production of bell pepper.

Effect of a bovine manure vermicompost leachate on yield of pepper (Capsicum annuum L.) hybrid Nathalie

Purpose The present study was aimed to investigate the effect of a bovine manure vermicompost leachate (BMVL) on growth, total chlorophyll content and yield of pepper (Capsicum annuum L.) hybrid Nathalie. In pepper, the effects of BMVL had not been studied before. Methods Six dilutions of BMVL (1:10, 1:20, 1:30, 1:40, 1:50 and 1:60 v / v), unfertilized soil and YaraMilaTM ComplexTM chemical fertilizer were tested. The experimental design was randomized blocks with four replications. The variables measured were the height of the plants, the diameter of the stem, the number of leaves, the total chlorophyll content, the length, the circumference and the weight of the fruits in four harvests. The yield per hectare in the experimental treatments was estimated from the total weight of the fruits obtained in the four harvests and the area occupied by the plants sampled. Results No substantial agronomic differences were observed in the growth variables nor in the total chlorophyll content between the experimental treatments. The estimated yields in the plots of all BMVL dilutions did not show significant differences among themselves or with chemical fertilization, and exceeded the yields of the plants in the treatment of unfertilized soil. Conclusion The results suggest that bovine manure vermicompost leachate can become a sustainable alternative for pepper production reducing fertilizer application rates, thus diminishing the contamination of the environment.

Growth and Phosphorous Absorption Rate of Red Pepper as Affected by Top Dressing Applications of Phosphorus Fertilizer in Different Cropping System

An experiment was conducted to study the effect of top dressing application of Phosphorus (P) fertilizer on the growth and P absorption rate of red pepper in different cropping systems of the upland. P fertilizer was applied with no treatment as control (CON), basal dressing application (BDA), 2 times-split of top dressing applications (2-TDA) and 3 times-split of top dressing applications (3-TDA). Red peppers were grown for 110 days and soil characteristics and crop growth were investigated every 20 days. Dry matter yield of red pepper significantly increased at the 2-TDA and 3-TDA but decreased at the CON and BDA due probably to the decrease or increase in available P. In particular, at 3-TDA there was an increase in growth and P absorption rate of red pepper. The fruit dry matter weight of red pepper receiving 3-TDA was 961.7 kg 10a-1, which was significantly higher than those receiving CON and BDA in Rainproof cultivation. In case of the Rainproof cultivation, we found out both P fertilization use effect and top dressing applications effect because there was low available P content of soil used in the experiment in comparison other cultivation type. Therefore, considering the dual goal of optimum crop growth and maximum P distribution instead of immobilization with soil, this study suggests that a testing of a site-specific proper application method of P including top dressing applications is prerequisite to achieving optimum agricultural productivity while minimizing nutrition quality misuse.

Evaluation of Sweet Pepper (Capsicum annum L.) Varieties as Influnced by Nitrogen Levels in Chitwan, Nepal

An experiment was conducted to assess the performance of sweet pepper varieties as influenced by nitrogen levels from August 2014 to February 2015 at Mangalpur, Chitwan. The experiment was laid out in two factorial Randomized Complete Block Design (RCBD) with three replications having sixteen treatments. Varieties and levels of nitrogen significantly affected growth, yield and qualitative parameters of fruits. Hybrid Indra and NS 632 performed better than open pollinated varieties viz. Sagar and California Wonder. Days to fifty percent flowering of NS 632 were earlier than California Wonder. Indra variety had the highest plant height (52.18 cm), number of secondary branches per plant (13.51) from 250 kg N/ha through chemical fertilizer while number of leaves per plant was higher in NS 632 variety (57.22) than Sagar variety (47.37). Indra variety showed the highest fruit weight (87.59 g) and total yield (39.45 t/ha) but NS 632 variety produced more number of fruits per plant (9.25) than California Wonder variety. This study showed that sweet pepper yield of hybrid varieties applied with 250 kg N/ha through chemical fertilizer was appropriate dose to get optimum yield under Chitwan condition.

Sweet peppers yield and quality as affected by biochar and compost as soil amendments under partial root irrigation

Owing to the arid and hot climate of Saudi Arabia, the use of water saving strategies in regional agriculture is imperative. This study aims to investigate the use of the partial root-zone drying (PRD) method in combination with the application of biochar (BC), compost (comp), and the combined application of both to improve the marketable yield and fruit quality of bell peppers grown in protected agriculture. Pepper plants were grown under full irrigation (FI, 100% ETc) and partial root-zone drying irrigation (PRD, 80% ETc) regimes and seven different levels of organic soil amendment: 2% BC, 2% Comp, 4% BC, 4% Comp, 1% BC + 1% Comp, and 2% BC + 2% Comp (w/w). We found that reduced irrigation (PRD) resulted in significant decreases in the average length, width, and wall thickness of fruit and reduced early, marketable, and total yields. However, several indicators of fruit quality were improved under the PRD irrigation regime, with fruit also having higher dry matter, vitamin C, and TSS content, and increased total acidity and total sugars values. In addition, PRD increased the N and Ca content of the fruit relative to fruit grown under the FI regime. The combined application of BC 2% + Comp 2% had positive effects on fruit length, width, and wall thickness and improved early, marketable, and total yields. The treatment also increased fruit dry matter, vit. C, TSS, TA, and TS, and improved fruit N, P, and Ca concentrations. Thus, the application of BC 2% + Comp 2% in combination with PRD could be used to increase fruit quality and yield in sweet pepper production while reducing the amount of required irrigation water by 20%. We conclude that the application of both BC and comp in combination with PRD is a novel and promising approach to improving fruit quality and yield in sweet pepper protected agriculture.
