A field experiment was conducted to assess the effect of different pruning and nitrogen levels on the growth and productivity of bitter gourd from March to July 2022 in Nawalparasi East, Nepal. The field experiment was laid out in a split-plot design with three replications. The treatment comprised three levels of pruning (No pruning, second generation (2G) pruning, and third generation (3G) pruning) in main plots and three different doses of nitrogen (100, 150, and 200 kg ha-1) in sub-plots. Observations on growth, floral, and yield parameters were recorded, analyzed, and presented. The research result revealed that 3G pruning with 200 kg ha-1 nitrogen level produced the highest fruit yield (16242.56 kg ha-1) at the fourth harvest. The yield trend showed higher fruit yield at higher nitrogen levels and 3G pruning at all dates of harvest. The increased fruit yield at higher nitrogen levels was because of more number of fruits per plant as well as longer fruit length and larger fruit diameter. The higher productivity in 3G pruning was mainly due to more fruit per plant at the fourth harvest. The results indicate a higher yield of bitter gourd at a higher level of nitrogen with 3G pruning.","PeriodicalId":247800,"journal":{"name":"Nepalese Horticulture","volume":" 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139145069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to detect potential inflorescence primordia and correlate it with observed bunches in vine. Bud dissection was carried out in a spur (having 4 buds from basal node towards apex) per vine of var. Himrod and var.

A survey was carried out from November 2018 to January 2019 to know the knowledge, skill, and behaviors towards chemical pesticides among vegetable growers, sellers, and consumers. The household survey was carried out with a well-designed questionnaire among 180 respondents, 60 each of vegetable producers, vegetable sellers, and vegetable consumers using the purposive sampling technique. The present study revealed that knowledge of chemical pesticides and their residue in vegetables, chemical pesticide handling skill, and behavior towards chemical pesticides among vegetable growers, sellers, and consumers was inadequate. The concerned authorities should stretch the extension services regarding pesticide use and post-use precautions to the nook and corners of Nepal as 60% of farmers seek the help of Agrovet for such information and rest either from neighbors or from manual. Sound policy formulation and implementation are necessary for judicious and rational use of chemical pesticides in vegetable crops and promoting non-chemical pest control measures. Such activities might solve pesticide-residue-related issues on the vegetable crop that makes vegetable growers, sellers, and consumers safe. Coordination among concerned organizations/agencies viz farmers group, consumers’ association and Government Organization, Non-Government Organization and International Non-Government Organization is necessary to address the issues of chemical pesticide in the vegetable supply chain.

While observing the fruit qualitative characters maximum fruit length was found in Pear Shaped (71.1 mm) and the minimum was found in Bari (50.2 mm). Similarly, the highest individual fruit weight was observed in Apple Guava (229.5 gm) and the lowest fruit weight was in Illam Selection (59.4 gm).

This review has its importance for standardizing the type and concentration of plant growth regulators in African marigold. Online journals, scientific papers, proceedings, books, thesis and lecture notes are the key reference site for this review. Gibberellins or gibberellic acids (GA3), ethrel, paclobutrazol, salicylic acid, Indole 3 Acetic Acid, Naphthalene Acetic Acid (NAA), Chlormequat Chloride and sea weed extract are the most widely used and proven biochemical with pronounced effect on growth, development and differentiation in marigold. Among these, 300 ppm, 350 ppm and 450 ppm of GA3 results higher plant height, minimum days for flower initiation and higher basal diameter respectively. Similarly, 450 ppm for higher number of branches and leaves per plant and 400 ppm of GA3 or 600 ppm of CCC has been found to impart higher number and weight of flowers per plants. Besides, 1000 ppm of CCC has been found more effective to impart higher productivity (yield/ ha) in African marigold.
