Optimization of medium composition for invitro proliferation and rooting of anther derived micro-shoots in African marigold (Tagetes erecta L.)
An efficient shoot proliferation response from the anther derived microshoots (1-2 mm) of two heterozygous populations of African marigold (Desi Orange and Desi Yellow) to various invitro media compositions was investigated. The best multiple shoot induction (about 3.34 shoots/explant and 11.57 shoots/explant) after 30 and 60 days of culturing respectively and minimum number of days taken for shoot proliferation (4.05 days) was observed after the microshoot explants were cultured on solid Murashige and Skoog medium (MS) supplemented with NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). 100 percent shoot proliferation was recorded in the MS medium devoid of any growth regulators and NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). Length of the shoots was also found maximum (4.14 cm) in the MS medium supplemented with NAA (0.1 mgL-1) + meta topolin (0.5 mgL-1). Between the two genotypes, Desi Orange showed better response in terms of shoot proliferation percentage (61.44%), days for shoot proliferation (8.52 days), average number of shoots per microshoots (2.16 and 6.48 shoots/explant) after 30 and 60 days of culturing and length of the shoots (2.71cm) than Desi Yellow. Maximum rooting (95.89%) and roots/shoot (38.11) were obtained with ½ MS + IBA (0.5 mgL-1). Also, Desi Orange had maximum rooting (91.40%) and roots/shoot (30.84). Meta Topolin and IBA were found superior in increasing the shoot and root growth respectively.
Direct and indirect methods for estimating gully erosion and proposals for management scenarios of the Funa Watershed in Kinshasa, DR Congo
The global erosive and sedimentary balances and its three ravines of geomorphological units between two successive levellings including 2019 and 2022, were indeed carried out and presented on the basis of LS MNT and LS Topography. Using the RUSLE model and topographic method, we proceeded to the description of the Funa watershed and the location of the ravines studied. The method of describing ravines involves the description of their geomorphological units, which requires the creation of a typology of forms, processes and factors of erosion and sedimentation within the ravines. Our descriptive method is complemented by a statistical analysis method to group the geomorphological units of the ravines according to the characteristics describing the processes and factors of erosion. Nearly 40% of the watershed surface is exposed to a soil loss rate of more than 25 tonnes per hectare per year, with an average of 45.8 tonnes per hectare per year across all watersheds in the study area. Indeed, the results show that the spatial distribution of soil loss zones classified as "high to critical" obeys specific conditions. According to the analyses, the characteristics of the areas most affected by this problem in the study area are those located on soils of a sandy nature, (Spolicsols). These terrains are usually found on medium slopes at an altitude of between 300 and 400 meters. However, the validity of these results is subject to debate, as these values may vary from one model to another depending on the methods adopted. Two scenarios were developed to determine the impact of these developments, and the results showed that the development of 16% of the watershed surface will reduce average erosion by more than 25%.
Assessing farmers knowledge towards Agri-Nutrition (A2N) in Uttar Pradesh and Telangana: A psychometric test development and impact analysis
Food environments improve the health and nutrition benefits of populations. Rapidly changing food systems, production and distribution patterns stress out to leverage the role of agriculture for nutrition. This requires enquiring the knowledge of farmers in both the fields of agriculture and nutrition for appropriate decision-making. The present study attempted to investigate Agri-Nutrition (A2N) knowledge level of 360 farmers from two agro-climatic regions of Uttar Pradesh and Telangana villages with a reliable and valid instrument development based on psychometric principles. The items with difficulty index (20-80), discrimination index (>0.2), point-biserial correlation (>0.2) were selected and administered to final sample. The findings indicate targeted efforts of providing nutrition education in model villages contributed to improved knowledge among farmers, which in turn positively affect nutrition security in the study area.
Amelioration of cold stress in marigold var. Pusa Narangi Gainda under North Indian plains
This experiment was conducted to investigate different strategies for alleviating cold stress in marigold for a period of two consecutive years (2021-2022 and 2022-2023) at the Centre for Protected Cultivation Technology (CPCT), ICAR-Indian Agricultural Research Institute, New Delhi. In this study, the marigold var. Pusa Narangi Gainda seeds were sown at three distinct sowing dates and seedlings were grown under two different growing conditions with the use of several treatments and their respective combinations. The parameters pertaining to growth and flowering were recorded and evaluated. Among distinct growing environments, the plants grown inside a low polytunnel were seen to exhibit superior growth compared to those under open field conditions. Whereas, in terms of the sowing date, October 15th recorded maximum in growth and flowering characteristics. In the context of various treatments, it was discovered that the combination of Chito Oligosaccharide at a concentration of 300 ppm with Arbuscular mycorrhiza showed favourable results as compared to control and other treatments. This study demonstrates the positive impact of utilizing low polytunnels under various sowing dates and treatments on the growth and flowering of marigold plants.
Influence of organic inputs and growing conditions on yield and yield related attributes of strawberry (Fragaria x ananassa Duch.)
Studies were conducted to evaluate the “Influence of organic inputs and growing conditions on yield and yield related attributes of strawberry (Fragaria x ananassa Duch.)” in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during the period 2020-2022. The field experiment was laid out in Factorial Randomized Block Design (RBD) with five treatments replicated three times under four different growing conditions with spacing of 30cm x 60cm. The four different growing conditions were rain shelter with insect proof net (S1) (top covered with 200 micron UV film and side wall of 40 mesh net), rain shelter without insect proof net (S2), net house (50% shade) i.e. S3 and open condition (S4). Treatments were FYM @ 180 g/plant (T1), rock phosphate @ 4.50 g/plant + microbial consortium @ 0.063g/plant (T2), T2 + vermicompost @ 45 g/plant (T3), T2 + enrich compost @ 45 g/plant (T4) and T2 + poultry manure @ 45 g/plant (T5).) .The yield attributes viz. number of fruit retained (19.33 nos), length (5.38 cm), diameter (4.26cm), volume (19.45 cc), average fruit weight (23.65g), fruit yield (457.88g/plant) was also found to be significantly higher in treatment combination T3S1 vermicompost @ 45 g/plant+ rock phosphate @ 4.5 g/plant + microbial consortium @ 0.063 g/plant in growing condition S1) in pooled analysis of both the years.
