“…Analysis of average value of all production cycles showed maximum fruit yield in PS-3-1 (28 kg/plant) in 2017-2018 and minimum in PS-5-1 (10 kg/plant) in 2014-2015 (Table 3). Singh et al [12] in a study on genetic variability and correlation for vegetative, reproductive and yield attributing traits in papaya, found maximum fruiting zone in PS-3 (129.8 cm) followed by a hybrid of PS-3 (128 cm), the dioecious parent of PS-3-1.…”

“…Therefore, Prakash et al [10] emphasized that the initial step of successful breeding programme will depend on selection of plants with tolerance/resistance against PRSV infection. Indian and exotic cultivars of papaya, and promising selections were screened for PRSV infection in Lucknow for using them in future breeding programme [11,12]. ICAR-Indian Agricultural Research Institute, Regional Station (IARI RS), Pune has developed PRSV tolerant dioecious lines, Pune Selection-1 (PS-1), PS-2, PS-3 and PS-5 [13].…”

Among major global threats to papaya cultivation, papaya ringspot virus (PRSV) is the most challenging one. In the absence of any PRSV resistant commercial papaya cultivar, PRSV management is restricted to minimizing yield losses. ICAR-Indian Agricultural Research Institute, Regional Station, Pune has developed PRSV tolerant dioecious papaya lines, Pune Selection (PS)-1, PS-2, PS-3 and PS-5. Being dioecious these lines have limited acceptability among farmers. Gynodioecious population from these lines were developed and characterized. They are numbered PS-1-1, PS-2-1, PS-3-1 and PS-5-1. These lines were characterized against prevailing commercial gynodioecious cultivar, Red Lady, for five generations. The average plant height of PS-2-1 and PS-5-1 (183 cm) was more than Red Lady (158 cm), however, stem girth of all lines was lesser than Red Lady. The fruiting height of all lines was less than Red Lady (87 cm). Length of the fruiting column of all lines was more than Red Lady (37 cm), except in PS-1-1. Fruit yield of all lines was more than Red Lady (16 kg/plant). Intensity of PRSV infection in Red Lady (48%) was considerably more than all lines. These lines can be used for developing PRSV tolerant gynodioecious papaya variety.

“…An example from a 2010 Ethiopian guide on cool season vegetable crops, seed production, and development practices describes head cabbage (common cabbage) as having a dense head of leaves, a short stem, and additional edible leaves [ 28 ]. The diverse shapes and sizes of cabbage heads across varieties encompass oblong, oval, or nearly circular forms, with cultivars displaying distinctions in the leaf size, shape, color, and head texture [ 29 ]. Clear descriptions of cabbage growth stages, though lacking standard terminology, are vital for pest management, as plant susceptibility varies, as outlined in subsequent literature ( Table 1 ).…”

Cabbage (Brassica oleracea var. capitata L.) holds significant agricultural and nutritional importance in Ethiopia; yet, its production faces challenges, including suboptimal nitrogen fertilizer management. The aim of this review was to review the possible effect of nitrogen fertilizer levels on the production of cabbage in Ethiopia. Nitrogen fertilization significantly influences cabbage yield and quality. Moderate to high levels of nitrogen application enhance plant growth, leaf area, head weight, and yield. However, excessive nitrogen levels can lead to adverse effects such as delayed maturity, increased susceptibility to pests and diseases, and reduced postharvest quality. In Ethiopia, small-scale farmers use different nitrogen levels for cabbage cultivation. In Ethiopia, NPSB or NPSBZN fertilizers are widely employed for the growing of various crops such as cabbage. 242 kg of NPS and 79 kg of urea are the blanket recommendation for the current production of cabbage in Ethiopia. The existing rate is not conducive for farmers. Therefore, small-scale farmers ought to utilize an optimal and cost-effective nitrogen rate to boost the cabbage yield. Furthermore, the effectiveness of nitrogen fertilization is influenced by various factors including the soil type, climate, cabbage variety, and agronomic practices. Integrated nutrient management approaches, combining nitrogen fertilizers with organic amendments or other nutrients, have shown promise in optimizing cabbage production while minimizing environmental impacts. The government ought to heed suggestions concerning soil characteristics such as the soil type, fertility, and additional factors such as the soil pH level and soil moisture contents.

“…It belongs to the family Asteraceae, originated in Mexico and was declared the national flower of this country 1963, which got its name by Cavanilles in the year 1791, to commemorate the work of Swedish Botanist Dr. Andreas Dahl, a pupil of Linneaus. Being a well-known flower florists blossom, dahlia tubers were sold each year in millions in North America and Europe [2].…”

An experiment entitled “Effect of seaweed extracts on the growth, flower yield and quality of Dahlia (Dahlia variabilis) c.v. Aditya Birla” was conducted to evaluate the response of dahlia to different growth regulators, Kelp @ 2ml and 4 ml and Biovita @ 2ml and 4 ml. Thirteen different treatment combinations were replicated thrice in a Randomized Completely Block Design. The investigation revealed that Biovita was very effective and recorded maximum days to seed germination, plant height, number of leaves, stem diameter, secondary branch number. Leaf area Significant influence of growth regulators was observed on various vegetative parameters. Flower diameter, flower number, diameter and fresh weight increased Significant influence of growth regulators was observed on various foral parameters. Highest flower numbers per plant and flower yield per ha was recorded treatment T11 (4 ml L-1Biovita, 5 days interval). Treatment T11 recorded higher net realization Rs. 506700 which was followed by treatment cost of cultivation with of Rs.170500.. Furthermore, highest Cost benefit ratio was recorded under treatment T11 (1:2.97).
