Agriculture is the main occupation of the people of Himachal Pradesh. Vegetable cultivation is facing challenges in profitability and economical use of resources. But a limited research has been done on resource use efficiency and elasticity of production in tomato, cauliflower and peas which are the major vegetable crops grown in Kullu. The present study was carried out in Kullu valley in the year 2019-2020 and multi-stage random sampling technique was used to select sixty farmers from different panchayats and villages on the basis of area they had under these crops. The elasticity of inputs used in the production of vegetables was worked out by fitting Cobb-Douglas production function. The sum of elasticity coefficients in case of tomato (Σbi = 1.22), cauliflower (Σbi = 1.56) and pea (Σbi = 1.31) were greater than unity which is statistically significant and shows increasing returns to scale. The ratio of marginal value product (MVP) to marginal factor cost (MFC) represented by value of r, was greater than unity in tomato for plant protection (8.38) and labour (1.05) which indicated their under-utilization. Value of plant protection (0.30) on the other hand was less than unity in cauliflower, which shows its over-utilization. In case of peas, values for fertilizer (-1.09), seed (-2.44) and FYM (0.87) showed these were over utilized. It is suggested that the farmers should be trained for judicious use of resources.","PeriodicalId":36766,"journal":{"name":"Journal of Horticultural Sciences","volume":"85 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84064453","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}

However, its production on Taiwan is limited by low productivity despite being regarded as a high-quality fruit. It is known that litchi’s leaves play a critical role in floral induction under low temperature. Thus, we hypothesized that the flower intensity in spring could be manipulated by altering the leaf quality in winter, thereby increasing crop load. In this pilot study, ‘Yu Her Pau’ trees were pruned in mid-December [early pruning (EP)], one of the common cultural practices carried out by growers in the region, as control or mid-January [late pruning (LP)]. This resulted in 50% and 100% canopy foliage for EP and LP trees, respectively, between mid-December and mid-January. At the peak blooming time in March, LP trees produced significantly more female flowers than EP trees (95.8 and 56.1/panicle, respectively) with no negative effects on initial fruit set number, fruitlet abscission, or fruit quality at harvest. Our results suggest additional mature leaves present on trees in mid-December onward may benefit litchi flower formation without affecting fruit retention. Thus, preserving leaves with delayed pruning might potentially mitigate the negative impacts of warmer winters due to climate change on litchi flowering.","PeriodicalId":36766,"journal":{"name":"Journal of Horticultural Sciences","volume":"83 5 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87652557","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}

In this study, the taxonomic aspects of genus Mimusops, were thoroughly studied to identify the most reliable characters for taxon delimitation. Our assessment was based on morphological characters representing habit, leaves, petioles, flowering pedicels, buds, floral parts, fruit and seed. Fieldwork have revealed the presence of four species, of which Mimusops kummel and M. zeyheri are new records. The latter species is represented in Egypt by M. zeyheri var. laurifolia. This variety has been neglected by many authors. Additionally, Mimusops elengi L. was believed to be cultivated in Egypt, but no materials have been encountered that could confirm it.

All the morphological and yield traits showed significant difference among the selected genotypes indicating the presence of adequate variations. The genotypes recorded morphological variation in terms of tree shape (semi-circle to irregular shape), foliage arrangement (dense to sparse), flowering time (early, mid and late), stem colour (dark brown, brown and light brown), bud colour (greenish white, pink, dark pink), petal colour (yellow and pale yellow), pod colour (greyish brown, brown, light brown and dark brown), pulp colour (light brown, brown and reddish brown), pod shape (straight, slightly curved, curved and deeply curved) and pod size (very big, big, medium and small). The analysis of variance revealed significant difference with respect to tree height, stem girth, pod traits, pod yield per tree (K-9 : 12.80 kg), number of pods per tree (NTI-52 : 989.07) and pulp per cent (K-9 : 48.87). Among the 16 genotypes, the genotype K-9 was found superior with respect to pod size, pod weight, pulp weight and pod yield per tree.

Fruits, vegetables, and spices of the region are highly nutritious and have a market within and outside the country. The paper is an attempt to assess the potential of horticulture in the region. To gauge the state-wise and regional growth trend and variability in area and production of these crops during the period 2009-2019, Compound Annual Growth rates and Instability Index have been computed from secondary data. The study reveals a rising regional growth trend with low instability for the production of fruits and vegetables and moderate instability for spices. This indicates the possibility of sustainable development of horticulture in all the Northeast states through strategic planning. Fruits and spices of the region also have a market in Middle-East and neighbouring countries. However, lack of commercialisation, poor market intelligence, and linkages are impeding the growth of exports. To unleash the true potential of horticulture, it is imperative to develop infrastructure, modernise farming and establish seamless value chains with greater market integration.","PeriodicalId":36766,"journal":{"name":"Journal of Horticultural Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89394695","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 evaluated cultivars included Santarosa, Ghatreh tala, Shams, Dargazi, No. 16, No. 17, Laroda, Simka, Bokhara, and Stanley. The results showed significant differences in the stem diameter. The union graft location in Shams, Laroda, Simka, Stanley, and Ghatreh tala cultivars on apricot rootstock was thicker than the scions and stocks. Phenolic compounds in the union graft decreased in all plum cultivars on myrobalan rootstock in comparison with other sites. Finally, the most phenolic accumulation belonged to the union graft on Santarosa, Ghatreh tala, and Shams on apricot rootstocks. Therefore, it seems that phenolic compounds in plums can be used as a biochemical marker in graft incompatibility.","PeriodicalId":36766,"journal":{"name":"Journal of Horticultural Sciences","volume":"99 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83333280","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}
