Employing empirical models to analyze stability of yield and quality traits in chili peppers (Capsicum species)

AbstractStability analysis plays a crucial role in plant breeding programs aimed at enhancing crop productivity and resilience. Chili yield stability studies based on the interaction of genotype × environment have been widely conducted, as stable yield is very substantial in the formation of sustainably high‐yielding chili varieties. Multi‐environmental trials, conducted across different seasons, locations, or both, are used to assess these G × E interactions through various statistical models. In this context, this review paper explores the understanding of stability analysis in chili breeding, the significance of genotype by environment interaction, and the methods employed in this domain, providing a comprehensive update on recent advancements in stability analysis specific to chili breeding. Furthermore, research studies conducted on stability analysis in chili breeding programs and software used to assess crop stability are featured, shedding light on the application, challenges, and future prospects in the field. The importance of stability analysis in developing stable genotypes and enhancing agricultural productivity amid evolving environmental conditions is herewith underscored. These insights are critical for breeding programs aiming to create robust genotypes capable of adapting to changing environmental conditions, ultimately contributing to more sustainable agricultural practices.

Characterization of the Morphology, Growth and Fruit Yield of Chilli (Capsicum Annuum L.) Genotypes Collected from the Eastern Black Sea Region of Türkiye

Capsicum annuum, native to Central America, specifically Mexico, is widely cultivated throughout Türkiye for its unripe green or ripe red fruits, known as "biber" in Turkish. In this study, a comprehensive assessment of morphological diversity, encompassing both quantitative and qualitative traits, was conducted. A total of 48 different genotypes of C. annuum, varying in colour shape, and size, were collected from the Pazar district and villages in Rize in 2014 and stored at +4°C. Planting of these C. annuum seeds occurred in May 2015 in trays filled with a mixture of peat and perlite at a 2:1 ratio under greenhouse conditions. When the seedlings reached the stage of having 4-5 leaves, they were transplanted into the field in June 2015. The data obtained on morphological characteristics were subjected to analysis of variance (ANOVA), principal component analysis, and hierarchical clustering analyses. The first six principal component axes accounted for 79% of the variance among the 48 genotypes. Hierarchical clustering revealed four main clusters, whereas ANOVA revealed significant differences in various morphological characteristics of 48 different genotypes of C. annuum. This study revealed substantial morphological variability within the C. annuum genotypes examined and hence provides valuable insights for geneticists and breeders, enabling the identification of populations with desirable characteristics for future integration into pepper breeding programmes

Seasonal Incidence of Scirtothrips dorsalis and Bemisia tabaci on Chilli with Studies on Comparative Efficacy of Insecticides and Botanical Oils

The study conducted at Sam Higginbottom University of Technology and Sciences in Prayagraj during the 2019 and 2020 kharif seasons provided comprehensive insights into insect population dynamics and insecticide efficacy against thrips and whiteflies in chilli cultivation. Key findings revealed significant pest population fluctuations, with thrips peaking at 16 per plant during the 43rd Standard Meteorological Week (SMW) in late October for both years. Whitefly populations reached up to 17.6 per plant, peaking during the 44th week in 2019 and the 43rd week in 2020, both in late October. Correlation analyses showed significant negative relationships between insect populations and temperature, wind velocity, and rainfall, while a positive correlation was observed with sunshine duration. Multiple linear regression models demonstrated that weather parameters collectively explained 69.8% and 70.4% of thrips population variability in 2019 and 2020, respectively, and 87.7% and 17.2% of whitefly population variability. Stepwise regression models revealed that in 2019, maximum temperature and rainfall jointly accounted for 46% of pest population variability. In 2020, the addition of wind velocity to these factors explained 83% and 56% of variability in thrips and whitefly populations, respectively. Insecticide efficacy evaluation showed acetamiprid as most effective against thrips (92.14% reduction) and imidacloprid against whiteflies (88.89% reduction). Thiamethoxam and imidacloprid demonstrated comparable effectiveness. Economic analysis highlighted imidacloprid's superiority, providing effective pest control, the highest chili yield, and the best cost-benefit ratios (1:8.30 in 2019 and 1:5.38 in 2020).

The influence of ameliorant, nutrient solution and bioferilizer on soil P, plant P uptake, and yield of red chili.

The productivity and quality of red chili are greatly influenced by soil conditions and the availability of nutrients. Nutrients play a critical role in the growth and development of red chili plants. This experiment aimed to determine the combination of ameliorant, nutrient solution, and biofertilizer on the population of phosphate-solubilizing bacteria (PSB), available P, P-uptake, and red chili production in Inceptisols. The experiment was conducted at the experimental field of the Faculty of Agriculture, Universitas Padjadjaran. The experiment used a Randomized Complete Block Design (RCBD) with seven treatments and four replications, consisting of control, NPK, and nutrient solution (NS) with doses of 0, 6, and 12 kg ha-1 biofertilizers. The dosage used in a single application was 15 g plant-1 of NPK fertilizer and 300 mL plant-1 of nutrient solution. The base fertilizer consisted of manure in the control treatment and an ameliorant in other treatments at a dose of 4 t ha-1. The results showed that the combination of ameliorant + NPK + 6 kg ha-1 biofertilizer increased PSB population (4.93 x 106 CFU mL-1), available P (15.4 ppm), and P-uptake (0.74 g plant-1). Meanwhile, the combination of ameliorant + nutrient solution + 6 kg ha-1 biofertilizer increased fruit diameter (15 mm), and length of red chili (17.3 cm). Correlation analysis indicated positive correlation between red chili production with stem diameter and fruit length, but a negative correlation with P-uptake. Regression analysis indicated that stem diameter and PSB population had the most dominant effect on red chili yield.

The results of the research showed that treatment with a POC dose of vegetable waste of 5 ml/l of water with mycorrhizal biological fertilizer of 2.5 g/lot had the highest influence on chili plant production of 48.33 g/plot or the equivalent of 193,32 kuintal/ha.

Ability of Beauveria bassiana to suppress Colletotrichum truncatum and increase the growth of chili plants (Capsicum annuum)

Anthracnose is a disease caused by Colletotrichum sp., which can reduce the quality and yield of red chili by 45-60%. This study aimed to determine the ability of different Beauveria bassiana isolates to control anthracnose in chili. The research employed a Randomized Block Design (RBD) consisting of 6 treatments and 5 replications. The treatments included a control and 5 different B. bassiana isolates (PD114, TD312, WS, BbKo, KT2B21). The observed variables included incubation period, disease incidence and severity, plant height, number of leaves, flowering time, and chili fruit weight. The results showed that the application of different B. bassiana isolates have effectively inhibited the development of Colletotrichum truncatum, which caused anthracnose in chili. B. bassiana has demonstrated the ability to prolong the incubation period of C. truncatum (5.40 days) and reduce the percentage of disease incidence (16%). Furthermore, the application of B. bassiana increased the height of chili plants (40.40 cm) and the number of leaves (32 leaves), accelerated the flowering time (42.80 days), and boosted chili production (178.25 g). The WS and TD312 isolates revealed the most significant results. Although the severity of the disease was not impacted, the 2 isolates provided notable agronomic benefits to the chili plants.

Response of Potassium Humate Extracted from Different Organic Sources on Yield and Quality of Green Chilli

Aim: In recent trend of organic farming, use of humic substances plays important role, as it act as biostimulants to boost the yield of crop. Humic substances can be easily obtained by locally available organic sources. Hence, three different organic sources viz. Farm Yard Manure (FYM), vermicompost, lignite were characterized for their physico-chemical properties and quality parameters along with nutrients to judge their quality and maturity to extract humic substances. The potassium salt of humic acid extracted from these three sources were used as foliar application at different concentrations to study their effects on yield and quality of green chilli. Study Design: The pot culture experiment was conducted in Completely Randomized Design comprising eleven treatments with three replications. Place and Duration of the Study: The experiment was conducted in rabi season 2021-22 at College of Agriculture, Karad, Maharashtra, India. Methodology: Three organic sources viz. Farm Yard Manure (FYM), vermicompost and lignite were used to extract humic substances (humic and fulvic acid). These organic sources were studied for their physico-chemical properties and quality parameters along with their nutrient status to compare their quality and maturity for extraction of humic substances. Humic substances obtained from these different sources were studied for their content and characteristics. The potassium humate extracted from these organic sources were used in a pot culture study on green chilli, comprising eleven treatments and three replications. The different levels of potassium humate (200 to 600 ppm) were used as foliar application on transplanted chilli at 30 and 45 days after transplanting (DAT) along with recommended dose of fertilizers (GRDF) for studying its effects on yield and quality of green chilli. Results: Among all the three organic sources, vermicompost was reported as the best organic source to extract humic substances from its physico-chemical properties viz. pH (6.9), EC (0.3 dS m-1), water soluble organic carbon (0.76 %) and C:N ratio (18.0), which are considered as quality and maturity parameters to obtain good quality humic substances. Nutrient status for macro and micronutrients were reported to be higher in vermicompost followed by FYM and least content in lignite. In the pot culture experiment, the foliar application of potassium humate extracted from vermicompost resulted in significant improvement in fresh and dry yield of chilli fruit and stalk as compared to potassium humate application extracted from FYM and lignite. Among the various concentrations used (200-600 ppm) for the foliar application of potassium humate, application @ 400 ppm extracted from vermicompost along with GRDF (T7) was reported as the best treatment resulting in significantly increase in the fresh and dry yield of chilli fruits and stalk. Further, it was noticed that the same treatment was observed to be effective in significant improvement of the ascorbic acid content as quality parameter in fresh green chilli fruits.

Identification of chili varieties (Capsicum annum) tolerance to root cutting based on stress selection indices and morphological traits planted in lowland area

Abstract. Kusumaningrum S, Sulistyaningsih E, Harimurti R, Dewi K. 2024. Identification of chili varieties (Capsicum annum) tolerance to root cutting based on stress selection indices and morphological traits planted in lowland area. Biodiversitas 25: 2063-2073. Root cutting is a potential technique for inducing root growth to increase chili yield. A set of four lowland chili varieties were evaluated under root cutting to identify tolerant variety. Stress selection indices such as stress tolerant level (TOL), Stress Susceptible Index (SSI), Stress Tolerance Index (STI), Yield Stability Index (YSI) and morphological traits responses were employed in screening of the variety. The research was arranged in randomized complete block design factorial, where the first factor was the lowland chili varieties ('Tanjung', 'Lembang-1', 'Tanjung-2', 'Ungara'), and the second factor was period of root cutting (0, 8, and 0 + 8 weeks after transplanting and no root cutting). The results showed that 'Kencana', 'Lembang-1', 'Ungara' were identified as the tolerant group under root cutting treatment and 'Tanjung-2' was identified as the intolerant group based on chili yield and stress selection indices. The tolerant group had chili yield increment under root cutting (0, and 8 WAT), which related to high root morphological traits (root diameter, root length, root surface area, and root dry weight density). Root cutting at 8 WAT gave the highest chili yield in tolerant group. The increased root growth in the tolerant group was contributed to promote shoot morphological traits (leaf number, leaf area, and plant height). Root cutting treatment in the intolerant group caused chili yield decrement, which was related to no increment of the root and shoot morphological traits. It was concluded that root cutting treatment at 8 WAT on tolerant group ('Kencana', 'Lembang-1', 'Ungara') can be used to increase chili yield in lowland areas.

Effect of Plant Growth Regulators on Growth, Yield and Quality of Chilli (Capsicum annuum L.)

Chili peppers are fruit-bearing plants from the Capsicum genus, and they are known for their spicy and pungent flavors. Chili peppers thrive in warm climates and can be grown in various types of soil. They are typically cultivated as annual plants, although some varieties can be perennial in suitable conditions Therefore, the present investigation was carried out at the Central Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during Kharif 2021-22 with a view to identify the effects of different doses plant growth regulators and its role in growth, yield and quality of Chilli variety TMPH-443. The experiment was laid in Randomized block design with 13 treatments and 3 replications with different combination in plant growth regulators. Under this experiment, overall, 13 treatment was taken including control. Different plant growth regulators (PGRs) used comprised of NAA, GA3, 2-4 D and Triacontanol all four at different doses. According to the current research, the use of Plant growth regulators (PGRs) had a significantly positive impact on the growth and development of Chillies. Among the various treatments that were evaluated, T5 (NAA @ 40 ppm spray) yielded the most favourable results in terms of growth viz., plant height, leaf area, early flowering and maturation and yield viz., fruit weight, length of fruit, fruit girth, number of fruits per plant, and yield per plant.

Chili Growth-Yield Improvement under Different Experience-Creativity Farmer Levels, Agronomical Components, and Their Partial Economic Analysis

Chili (Capsicum annuum L.), though it is one of the strategic and important vegetable commodities in Indonesia; still faces a main problem, i.e. low productivity with 7.78 tons ha-1 nationally and 6.45 tons ha-1 specifically in Jawa Tengah. Consequently, the improvement of chili growth yield under different experience and creativity farmer levels (ECFLs), components of agronomy (ACs), and their economic analysis partially was addressed as the main objective of the research. C. annuum ‘Akar’, healthy and farmer seedlings were used in the field research. The factorial experiment was arranged in a randomized complete block design with three replications. ECFLs from high (ECFL-1), moderate (ECFL-2), less (ECFL-3), and initially developed (ECFL-4) were used as the first treatment, and five different ACs with gradual component reduction of ACs-1, ACs-2, ACs-3, ACs-4 and ACs-5 as second treatment. The research clearly revealed that different seedlings, ECFLs, and ACs significantly affected the ‘Akar’ growth yield. Cultivation of the healthy seedlings by ECFL-1, who had ± thirty years’ experience in chili cultivation and fast response to all and potential problems during chili cultivation, under ACs-1, as a complete and optimal ACs, increased vegetative growth and yielded 417.8 flowers and 289.7 fruits plant-1, 1,040.6 g chili plant-1, and 1,044.8 kg chili plot-1; 110-337% improvement; IDR. 16,750,081 farmer income from 250 m2 plot size; and 4.77 R/C ratio, respectively. However, for positive income, R/C ratio, and low production cost for all farmers, further applications of ACs-2 were promisingly chosen. Entirely the optimal growth yield of chili was established by using healthy seedlings, choosing suitable Acs, and paying more attention to the ECFL. The results can be applied to other chili types and varieties.

Effect of Bio-stimulants on Growth, Yield, Quality and Biotic Resistance in Chilli (Capsicum annuum L.)

In 2021, a field experiment was conducted out at ICAR-Krishi Vigyana Kendra in Bengaluru Rural District, Karnataka state, India, to investigate the impact of bio-stimulants on the growth, yield, and quality of chillies (Capsicum annuum L.).

The results indicated that the maximum plant height (87.80 cm), primary branches (9.13), secondary branches (18.27), root length (27.07 cm), number of fruits per plant (58.33), fruit length (16.82 cm), and fruit diameter (1.31) with less incidence of pests such as white fly, thrips and murda complex were recorded with seedling dip and foliar application of amino acid-based bio-stimulant.

Hasil Dan Nisbah Kesetaraan Lahan Dua Varietas Cabai Merah (Capsicum annum L.) Yang Ditumpangsarikan Dengan Kacang Tanah Di Lahan Kering

Drylands with limited resource support need to increase their productivity. One indicator of land productivity is the land equivalence ratio (LER). This research aimed to study the growth and yield of red chili due to the effect of varieties and peanut planting times in intercropping systems to increase dryland productivity. One experiment was conducted in Amor-amor Hamlet, Gumantar Village, Kayangan Sub-district, North Lombok Regency, from March to August 2023. The red chili varieties tested were Baja MC (hybrid) and Landung (non-hybrid). Meanwhile, peanut (Hypoma 2 variety) planting time was at the same time, one week after planting (WAP) of chili and 3 WAP. The treatments were arranged factorially using a Randomized Block Design with three replications. All component crops had monoculture treatments to calculate LER. The results showed no interaction between variety and planting time on all parameters observed. Variety had no significant effect on growth and LER but significantly affected the yield of chili. The Landung variety produced higher yields than the Baja MC variety. Planting time treatment had no significant effect on growth and LER but significantly affected the yield of chili. The planting time of peanut that produced the highest yield was 3 WAP. The intercropping of chili with peanuts at all planting times increased dryland productivity with LER values greater than 1.0
