Physical and functional properties of Indian indica subset of 3k rice germplasm
Half the world's population relies on rice (Oryza sativa L.) as their primary source of nutrition. The quality of the rice grain is incredibly valuable to breeders, farmers, and consumers as the population grows and the variety of needs for rice expands. The milling, aesthetic, eating, cooking, and nutritional properties of rice grains are the four most important aspects of rice quality. In the present study out of 250 lines, 80 lines fell under long bold grain type, 73 lines fell under medium slender grain type, 65 lines fell under short slender grain type, 23 lines fell under long slender grain type, and 9 lines under short bold grain type. Among 250 3K lines the alkali spreading score was ranged from 3 (low, intermediate spreading) to 6 (High alkali spreading or low GT), as per the classification, 8 lines fell under low to intermediate alkali spreading, while 120 lines showed intermediate spreading (intermediate GT) and majority of the lines (122 lines) was observed to have high alkali spreading value or low GT. Therefore, from the study it can be concluded that 110 3K rice lines presented good physical traits like grain length, gel consistency and alkaline spread ratio.
Effect of Barnyard millet seedlings age on growth, production and quality
Barnyard millet is an essential climate-resilient crop and nutri-cereals. The age of the seedlings at transplantation determines the crop growth, chlorophyll content and yield-related attributes. The field experiment was conducted at the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai. Barnyard millet (C.O. (K.V.) 2 seeds were used as base material. The experiment was conducted for two seasons (2017-18) with three replications. The treatment details are direct sowing of seeds, transplanting 12 Days old seedlings, 18 Days old seedlings, 24 Days old seedlings and 30 Days old seedlings. Barnyard millet raised from 24 days old seedlings recorded more growth (146.3 cm), dry matter production (229.6 g plant-1), total chlorophyll content (1.297 mg g-1), productive tillers (7.1), panicle length (25.40 cm), seed yield (3072 kg ha-1) and 1000 seed weight (3.11 g) compared to direct sown crop (134.3 cm, 169.3 g plant-1, 0.627 mg g-1, 5.8, 23.70 cm, 2688 kg ha-1 and 2.70 g) The qualities of the resultant seeds were also higher in crops raised by 24 days old seedlings. The germination per cent increase over direct sown crop is 9 in resultant seeds of 24 days old seedlings transplanted. The reason may be due to better nutrient uptake, water relations, enhanced CO2 fixation and effective assimilating partitioning. Thus, transplanting of 24 days old barnyard millet was better than direct sown and other seedlings to get higher yield.
Digital technology-enabled structural transformation and market of agricultural commodities
The agricultural sector has undergone different transformation phase which has led to improved proficiency, yield, and productivity. The upsurge of technology in agriculture could be the most transformative agent. This is because agricultural innovation will not only transform farming mechanisms but as well change the entire supply chain. Technology adoption in agriculture will positively influence farming operations and control input supplies, processing and retailing, price, and sales of agricultural commodities. Against this backdrop, this study empirically investigates the point of sales where the deployment of digital technology becomes significant. The study utilised Wave 4 (2018/2019) of the Living Standards Measurement Studies (LSMS), Integrated Survey on Agriculture (ISA) for the empirical analysis and applied the multinomial logit regression to answer the research question. The result shows that across various points of sales, technology adoption is significant for all the actors. However, though significant for all actors in the sale chains, the estimated coefficients slightly differ. The study concludes that there is a need to lower the cost of digital technology, such as the cost of a mobile phone and internet usage. To lower the cost of a mobile phone and the internet, and to enhance accessibility, especially in rural areas, the government and donor agencies need to invest in infrastructure to foster healthy competition in the telecommunication industry. This will lower the cost of a basic monthly data plan, because, with the current rate of mobile data plans and the speed of exhaustion, not many farming households, especially those in rural communities can afford it. Besides, taxes on ICT (e.g mobile phones and internet) tools which are in most cases, excessively high to afford should be lowered. Similarly, there should be support for public internet access points (e.g., building of masts in all localities), and digital training for rural farmers to foster technology adoption.
NON-GENETIC FACTORS AFFECTING MILK FAT PERCENTAGE UNDER SMALLHOLDER DAIRY SYSTEM IN INDIA
Crossbred cows' milk fat percentage data were collected from the Bharathi Agro-Industrial Foundation, Pune. The phenotypic data collected were from smallholder dairy systems from six states from 2016 and 2022. The data were subject to quality control and R statistical software was used to find the significance among the non-genetic factors affecting the milk fat percentage. The overall mean milk fat percentage was 3.83±0.81 among the crossbred cows. The mean values for different years ranged between 3.47±0.24 and 3.92±0.88, whereas the mean values for the three seasons were 3.82±0.79, 3.82±0.82 and 3.86±0.82 respectively. The later stage of lactation had a higher mean of 3.98±0.78 as compared with 3.57±0.82 during early lactation. A significant difference (P<0.001) was noticed among all the non-genetic factors considered for the present study. The results will be useful to study the performance of crossbred under different environmental conditions.
PROSTHETIC REHABILITATION OF A SOFT-SHELL TURTLE
A softshell turtle was presented with a history of vehicular collision. Clinical examination revealed shell fracture in the carapace as well as hind limb paralysis. Turtle was bright and alert and its excretory system was also functional. External fixation was done using the adhesives to fix the carapace. As the turtle was trying to move with its fore limbs hence it was decided to place the prosthesis to support its hind body and further movement. Supportive medicines and physiotherapy were also given to revive the normal functions. In this case, internal organs were not injured which made the turtle to survive the trauma. The practice of prosthesis is common in mammals but we tried the same in the reptile which proved to be successful.
