Effect of sink modification within a capitulum on seed quality of marigold
In India, marigold (Tagetes spp.) stands out as a prominent flower crop, widely cultivated for various purposes such as loose flowers, cut flowers and pot plants. However, the inconsistent seed development in the central portion of the capitulum can lead to poor seed quality. To address this issue, a study was conducted on three marigold varieties (Pusa Deep, Dainty Marietta, and Pusa Bahar) during both rainy and winter seasons in Delhi. The research aimed to understand the impact of sink modification within the capitulum on seed quality parameters. Three distinct treatments were implemented for sink modification: removing outer and middle whorls (T1), maintaining a single flower per branch (T2), and a combination of maintaining a single flower per branch while removing outer and middle whorls (T3). The study extensively examined seed quality parameters, encompassing seed germination, seedling length, seedling dry weight, vigour indices, seed characters, and biochemical traits. Results revealed that sink modification, specifically in T3, significantly enhanced seed quality. T3 exhibited superior characteristics, including higher germination (48.3%), increased seedling length (9.6cm), greater seedling dry weight (12.0mg), and higher vigour index-II (582.8). Remarkably, T3 recorded maximum values for the 1000-seed weight (1.5g), area size (11.5mm2), seed length (12.8mm) and perimeter length (28.1mm). Also, T3 had higher total soluble content (23.63mg/gm FW) and sucrose synthase activity (1684.81μg/min/gm FW). This study underscores the significance of sink modification in enhancing marigold seed quality, revealing that competition for food reserves significantly influences variations in seed quality among different floret positions.
Effect of different N P K levels on growth, yield attributes, yield and quality of Indian mustard (Brassica juncea L.) Under Grid Zone of M P(India)
A field experiment was conducted during rabi season 2014-15,2015-16 and 2016-17 at the RVSKVV- Zonal Agricultural Research Station Morena. To study the effect of different fertility levels on growth, yield attributes, yield and quality of Indian mustard (Brassica juncea L.). Treatment consisted of three levels of nitrogen (80, 100 and 120 kg ha-1), two levels of phosphorus (20 and 40 kg ha-1) and two levels of potassium (0 and 30 kg ha-1) were evaluated in three replication with randomized block design. Application of 120 kg N + 40 kg P2O5 + 30 kg K2 O ha-1 produced significantly higher seed yield (3342 kg ha-1) and other growth and yield attributes viz. secondary branches/plant (14.4), siliquae/plant (462.6), seeds/siliqua (15.33), length of siliqua (5.78 cm), Seed weight /plant (39.90g),1000-seed weight (6.85 g), oil yield (13.44 kg ha-1) as compared to application of 80 kg N + 20 kg P2 O5 + 0 kg K2Oha-1. Net return and B:C Ratio was also recorded higher with application of 120 kg N ha-1 and it was gained Rs. 14141 ha-1and Rs. 7523 ha-1higher net returns over application of 80 kg and 100 kg N ha-1Hence, the farmers could economically benefited by using Indian mustard cultivar RH-749 with recommended doses of fertilizers.
Impact of COVID-19 on Food Security: Insights from Rural-Urban Fringe of Bangalore, India
This study examined the impact of COVID-19 on food security across the rural-urban interface of Bangalore. The primary data for the study was collected from 482 households through telephonic survey. The Household Food Insecurity Access Scale (HFIAS) approach was used to estimate the prevalence of food insecurity. The study found that during the COVID-19 pandemic, more than 70 per cent of the households were food secure across rural, transition, and urban gradients of the north and south transect of Bangalore, while the percentage of food insecurity ranges from 7 to 30 per cent. Variables associated with food security status in the rural-urban interface of Bangalore were analyzed using multinomial logistic regression. The results revealed that COVID-19 had positive influence on food insecurity status. The adverse effect of COVID-19 pandemic contributed to a rise in food insecurity, low dietary consumption, and malnutrition. Thus, study highlighted the need for further investment in targeted social protection strategies and safety nets as part of multi-sectoral solutions to improve household food security during such pandemic periods.
Diversity among rough lemon of Assam in accordance with tree and leaf characters
Rough lemon is considered as the third most important citrus species of North Eastern Region of India. This rank is addressed to it not only because of its importance as a potent rootsock but also because of its nutritious, delicious and aromatic fruits. But due to highly cross pollinated nature of citrus, there is a wide variability of the species visible in the region. This variation is mainly recognised after the bearing of fruits. However, the leaf and tree characters can also be considered for identification and grouping of jambhiri species of different types. In this paper, clustering of collections was done based on leaf and tree characters. Locational diversity of rough lemon can also be observed and effect of location is also found profound from this study.
Various physical aspects in Chrysanthemum cv. Zembla influenced using LED lights in a growth panel
LED technology has emerged as a recent trend in alternative lighting system in greenhouses as well as growth chambers for various horticultural crops. The experiment was conducted in CPCT-IARI (ICAR), New Delhi under a constructed growth panel system. Potted plants of Chrysanthemum morifolium cv. Zembla were used as an experimental crop. The lighting sources consisted of: Fluorescent light, LEDs (red, blue, white) and mixture of LEDs (80% red and 20% blue). The various LED sources had a significant impact on various physical parameters. The treatment with 80% red and 20% blue LED resulted in an overall increase in height, stem diameter, leaf area and number, and leaf area index. Whereas, least increase in plant height was observed with blue LED, Leaf area, number and leaf area index were observed to be minimum in white LEDs. This LED system can prove to be a beneficial investment in plant programing and to get greater stem length as desired by the cut flower market.
