This study aims to determine the insecticidal effect of Mentha rotundifolia essential oil on the post-harvest cereal pest Rhyzoperthadominica and to evaluate the doses and times required to kill 50% and 90% of the insect populations through two tests: contact and inhalation. The results show a strong biocidal effect on adult of Rhyzoperthadominica due to the different doses applied over time. The lethal dose DL50 was estimated to kill 50% of the insects with 0.377 µL in the contact test, while the lethal doses DL50 and DL90 were estimated to kill 50% and 90% of the insect population with 1.187 µL and 4.390 µL in the inhalation test. The essential oil of Mentha rotundifolia is toxic and can thus be used as a biopesticide.
This research investigated the interrelationship between sorghum yield, traits related to shoot fly resistance, and their combined influence on green fodder yield. Two hundred and ten Recombinant Inbred Lines (RILs) were evaluated during the kharif season of 2018 at the Instructional Dairy Farm of the Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India. Correlation among 18 measurable traits was computed along with the direct and indirect effects of seventeen independent traits on green fodder yield. Green fodder yield exhibited highly significant positive correlation with dry fodder yield followed by stem diameter. Path coefficient analysis revealed that dry fodder yield, stem diameter, days to emergence, plant height, leaf length, leaf width, 1000 grain weight have direct positive effect on green fodder yield. Selection based on these traits, either individually or in combination, could effectively identify high-yielding lines for green fodder production, contributing to enhanced shoot fly resistance in sorghum breeding programs.
Utilizing a half -diallel mating design, eight parental genotypes were crossed to generate F1 crosses, under water deficit (rainfed) conditions. Analysis of variance of combining ability revealed the significant (p<0.01) influence of both general combining ability (GCA) and specific combining ability (SCA) on the 17 traits under study. C306 was identified as the superior general combiner for traits such as plant height, peduncle length, thousand grain weight, biological yield per plant, and grain yield per plant. UP2572 exhibited the best general combining ability for canopy temperature depression, flag leaf area, and awn length. The cross C306×WH1142 was identified as the best combination for days to heading, biological yield per plant, and grain yield per plant, while for grain filling duration and normalized difference vegetation index (NDVI), the cross PBW660×WH1080 was identified as the best. Non-additive gene action predominated across all the traits examined. The dominance ratio revealed that the dominance gene action governed fourteen traits except for days to heading, days to maturity, and the NDVI those demonstrating overdominance. The identified parental lines and cross-combinations represent useful genetic resources that can withstand water deficits, and their progenies in later generations demonstrating superior trait performances over those of their parents can be employed in breeding for water deficit stress tolerance. Furthermore, the genetic insights obtained can be used to develop breeding strategies for improving drought tolerance traits, which will lead to the development of resilient wheat cultivars for water-deficit environments.
A study was conducted by research scholar of Department of Veterinary & Animal Husbandry Extension Education, ANDUAT, Kumarganj, and Ayodhya District of Uttar Pradesh. The present study has been conducted in purposively selected Ayodhya district of Uttar Pradesh to understand the Entrepreneurial behaviour of dairy farmers. A total of 120 dairy farmers were selected randomly from 12 villages of 4 blocks. A village-wise list of dairy farmers was prepared and from that list, ten dairy farmers were selected randomly from each village. The quantitative and qualitative data were collected through interview schedule, discussion, observation and available secondary sources. Majority of dairy farmers 38.33 per cent were belonging to medium level Entrepreneurial behaviour toward the dairy farming practices in research area. 49.17 per cent had medium exposure to the media exposure of communication in the research area. However, their decision-making skills with regard to dairy activities and the planning and sale of milk, khoa, and paneer were hampered by their poor level of education, precarious financial situation, and lack of training. Socioeconomic profiles like age, education, family size, family type and more social participation compression to other socioeconomic status have good Entrepreneurial behaviour in our research area.
In India due to non-availability of crop residues during winter season at high altitude areas of north eastern region, animals like Yak (Bos grunniens) and Mithun (Bos frontalis) have to suffer scarcity of food. The scarcity of food results in decreasing of milk production, deterioration of body weight and low fertility. To maintain a good livestock production of Compressed Feed Block (CFB) is one of the main options that is available. Though feed block making machines are available in the market, but those machines are costly and difficult to transport in the hilly areas. Those machines are mainly run with electricity which is also creating a problem to run in the interior areas of the region. Therefore, the objective of this research is to design and developed an efficient and affordable feed block making machine useful for the Yak and Mithun farmers of the region. The machine mainly works on hydraulic principle that is used to produce the compressed feed blocks. The fabricated machine consists of a 10 – tonne capacity hydraulic jack, frame and a cylindrical mould. Four samples of feed blocks are produced with different ratios of raw materials under the pressure of 5, 6, 7 and 8 MPa, respectively. The raw materials that is used for producing the feed blocks during the research are rice straw, rice bran, molasses and mustard cake. With this machine a feed block of size 130 mm diameter and 5 mm wall thickness can be produced. Physical properties like shatter index is evaluated and out of which sample 4 has got a good shatter index with retention of 82.1% of its weight whereas the percentage retention of sample 1 is 71.3% i.e. the least among 4 samples.
