Potassium (K) fertilizer application, as a component of the improved technologies necessary to maximize crop yield and quality, is often used to correct the plant, soil and environmental factors that limit K availability. The effects of 0, 30, 60 and 90 kg K2O ha-1 were studied on hot pepper (Capsicum annuum L; Atarodovariety) in 2014 and 2015 on the Teaching and Research Farm, Ekiti State University, Ado-Ekiti Nigeria in a Randomized Complete Block Design with four replicates. Each K rate was mixed with 75 kg N and 25 kg P2O5 ha-1 and applied 2 weeks after transplanting 5-week old seedlings spaced 60 cm × 40 cm apart. The data of growth parameters were collected at 2 weeks after treatment (WAT) and fortnightly till 10 WAT, number and weight of ripe fruits and fruit proximate composition. The plant height, number of leaves, leaf area and dry matter increased with age and K rates to highest values at 10 WAT and 90 kg K2O ha-1 in both years. The number of fruits, fruit and seed yield ha-1, fruit size, fruit length and breadth and pericarp thickness increased linearly from the control to the highest values at 90 kg K2O ha-1.The number of fruits and yield at 90 kg K2O ha-1 were 1.253×106, 14.24 t ha-1; and 3.73×106, 14.94 t ha-1 in 2014 and 2015, respectively but the 60 kg K2O ha-1 gave the highest agronomic efficiency. The slight increase in fruit moisture content would not predispose fruits to deterioration while the crude protein and fat, carbohydrate and ash contents, vitamin C and mineral nutrients increased significantly making K application necessary to balance the fertilizer protocol for optimum hot pepper production.

Phosphorus Fertilizer

Phosphorus deficiency is widespread in the soils in Nigeria which makes phosphorus fertilizer application at appropriate rates a component of the improved technologies needed for hot pepper (Capsicum annuum L) production. Atarodo (rodo) variety of hot pepper is cultivated in all agro-ecological zones and gives low fruit yields of variable quality which should be maximized with phosphorus fertilizer use but the information on the requirements is limited. The growth and fruit yield responses of rodo to phosphorus fertilizer were evaluated in 2013 and 2014 at Ado-Ekiti, southwest Nigeria in order to determine the optimum rates. The phosphorus fertilizer was applied at 0, 20, 40 and 60 kg P2O5 ha-1 in four replicates arranged in randomized complete block design. Data were collected on growth parameters from 2 weeks after fertilizer treatment and at 2-week intervals, number and weight of ripe fruits, fruit parameters and proximate composition, vitamin C and mineral contents. The growth parameters increased with age; plant height, number of leaves, leaf area and dry matter yield of plant portions showed linear increase up to the 60 kg P2O5 ha-1 rate. The 60 kg P2O5 ha-1 rate gave the highest fruit and seed yields in both years but the agronomic efficiency was maximized at 60 and 20 kg P2O5 ha-1 in 2013 and 2014 respectively. The fruit proximate composition, minerals and vitamin C contents increased to the highest values at 60 kg P205 ha-1. The linear responses to 60 kg P2O5 ha-1 in soils containing low available P suggest that higher rates and soils with variable P contents should be the focus to attain the optimum rates.

Capsicum Annuum L

The fruit yield and quality of hot pepper, Capsicum annuum L., is very low in Ethiopia mainly due to the lack of improved cultivars. The objective of this study was to evaluate the combining ability for yield and yield contributing characters in order to apply an appropriate breeding methodology for the improvement of yield and the contributing characters. Seven diverse cultivars, two local cultivars and five introduced promising inbred lines, were crossed in a half-diallel. The parents and F1s were grown at Melkasa Agricultural Research Center in 1999 and 2000. The experiment was arranged in a randomized complete block design with three replications of ten plants per row. The green fruit yield and eight yield contributing characters were recorded from eight plants in each replication. The analysis of variance and estimates of GCA and SCA were significant for most of the characters studied. Significant GCA and SCA values were recorded for most of the characters, revealing that both additive and non-additive gene effects were involved in genetic control. A lower average degree of dominance was also recorded for some of the characters. Although none of the parents was a good general combiner for all the traits, some parents showed high GCA effects for some of the economic traits, suggesting that these parental lines could be considered simultaneously while formulating a breeding programme for improving fruit yield and yield contributing characters. The majority of the crosses also depicted significant SCA effects in the desirable directions.

A field experiment was conducted during rabi season of 2019 at farmer’s field in Panruti near Cuddalore district (Tamil Nadu) to study effect of organic manures as INM component on growth, yield and quality of chilli (Capsicum annuum L.) in a randomized block design. The treatments consisted of recommended dose of fertilizers at two levels (160:60:30 and 120:45:22.5 kg NPK ha-1) and organic manures (20 t FYM ha-1, 50 kg Bio ash ha-1, 5 t press mud granules ha-1, 20 kg Sea weed extract granules ha-1 and 5 t neem cake ha-1) and replicated three times. The growth and yield parameters of chilli were significantly influenced due to application of organic manures. Among the treatments, 75% RDF + 20 t FYM + 20 kg Sea weed extract granules + 5 t neem cake ha-1 (T8) exhibited better performances of growth and yield parameters of chilli cv. Indus 13. The maximum values of growth parameters such as plant height, leaves plant-1, branches plant-1, canopy volume, chlorophyll content in the leaves and net photosynthetic rate were observed in this treatment (T8). The yield parameters such as days to first flowering, days to 50% flowering, flowers plant-1, fruit set, fruits plant-1, fruit length, fruit girth, pericarp thickness, pulp seed ratio, single fruit weight, total fruit yield (28.18 t ha-1) and quality parameters like capsaicin content (0.76%) and ascorbic acid content (171.3 mg g-1) were highest in this treatment (T8) suggested this is the best integrated nutrient management combination for chilli. Application of 100% RDF (160 : 30 : 30 kg ha-1) proved inferior in respect of growth and yield of chilli.

Green pepper (Capsicum annuum L.) is an important vegetable in the Kingdom of Eswatini. However, there is rare information on pepper production using cattle manure.  The experiment was conducted at the University of Swaziland, Luyengo Campus, in the Horticulture Department Lath-house to determine the effects of different rates of cattle manure on the growth and yield of green pepper in order to come up with a suitable application rate for green pepper. Cattle manure was applied at different rates of 20, 40, 60 and 80 tons/ha in a Randomized Complete Block Design, while 2:3:2 which was used as a control was applied at 150 kg/ha. For every increase in the application level/rate of the cattle manure, there was a considerable increase in the growth parameters that were measured. Results obtained from this experiment indicate that applying cattle manure at 80 tons/ha gave relatively higher yields. This cattle manure rate can be used by farmers in green pepper production.

The production of `Jalapeño' hot pepper has been increased in the last 10 years in about 6.21% during the period between 1992-2003, with a growing rate of 72%. In Mexico, is an important produce, because it is considered part of the traditional Mexican diet as well as its high productive level. One of the most frequent problems in this crop is the low production of fresh fruits caused by an inadequate fertilization. The objective of this research was to evaluate the effect of four fertilization formulas on the yield of fresh fruit of hot pepper variety Jalapeño cultivar Grande under irrigation conditions The evaluated formulas were (N-P-K-S): 1) 58-51-35-12 (control); 2) 78-68-46-16; 3) 97-85-58-20; and 4) 117-102-69-24. Treatments were distributed under a completely randomized block design with four replications. The formula 117-102-69-24 showed the highest values in the plant height and number of fruits with 62.5 cm, and 48 fruits, respectively. This formula also showed the highest values on equatorial and longitudinal diameters, and fruit weight with 3.36 cm, 11.26 cm, and 33.66 g, respectively. The total yields per plant and per hectare was 1.54 kg; and 38.22 t was obtained with the formula 117-102-69-24. The formula with the higher units of each element showed the best performance and exhibited the highest yield of fresh hot pepper, it was more productive than the control treatment commonly used by the hot pepper growers in Colima.

ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut. Terjadinya penggalian tanah lebih dari 2 meter dari lapisan atas untuk pembuatan batu bata merah melampaui kemampuan tanah untuk membentuk struktur tanah kembali, sehingga tanah-tanah yang sebelumnya merupakan tanah pertanian ini dapat digolongkan menjadi tanah terdegradasi dengan sifat kimia kurang subur dan pemanfaatan kembali untuk pertanian memerlukan pemulihan dan input pupuk yang cukup. Penelitian ini bertujuan untuk mengetahui formula pupuk cair organik (PCO) plus yang digunakan bersama NPK pada tanah terdegradasi guna meningkatkan kembali produktvitas tanahnya. Rancangan yang digunakan adalah RAK sederhana dengan 10 kombinasi perlakuan PCO plus bersama NPK yaitu A = Kontrol (tanah terdegradasi, tanpa pupuk), B = 0% PCO + 1 NPK, C = 0,25% PCO + 1 NPK, D = 0,50% PCO + 1 NPK, E = 0,75% PCO + 1 NPK, F = 1,00% PCO + 1 NPK, G = 0,5% PCO + 3/4 NPK, H = 0,5% PCO + 1/2 NPK, I = 0,5% PCO + 1/4 NPK, J = 0,5 PCO + 0 NPK, dan K = 1 NPK tanah normal. Semua perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa tanah terdegradasi bekas tambang batu bata merah memerlukan konsentrasi PCO di atas 0,5% sampai dengan 1% apabila diaplikasikan bersama 1 dosis NPKstandar. Hal ini mempu mengimbangi serapan hara P, Ca, dan B serta persen fruitset pada komoditas cabai setara dengan tanah normal.Kata Kunci: Cabai, NPK, Pupuk Cair Organik (PCO), Tanah terdegradasi
