Indian honey bee (Apis cerana indica F.) is present throughout our country except in the plains of north India. The queen bee is the mother of the colony, which rules over workers. As it is the source of all the hereditary characters, the colony can be improved by producing a goodquality queen. Even though biologically similar to A. mellifera, there were no ample studies on queen rearing in Indian bees than Italian bees. To unveil artificial queen rearing technique, queen cell cup size, type, and quality of the priming material were optimized based on acceptance and adult emergence. Queen cell cups of different sizes viz., 4 mm, 5 mm, 6 mm, and 7 mm in diameter, were used. Among them, 7 mm diameter cup showed the highest larval acceptance (28.33%) and adult emergence (25%). Priming media viz., water priming, royal jelly priming, diluted royal jelly priming, honey priming, and honey + royal jelly priming were fed to the colonies. Among them, diluted royal jelly showed the highest acceptance with 29.2% and adult emergence of 27.1% followed by, royal jelly (16.7% and 12.5%), honey + royal jelly (10.4% and 6.5%), honey (8.3% and 4.2%), and water (2.1% and 2.1%) respectively. The queen cell cups were prepared artificially from plastic cups too. But they were not readily accepted by worker bees. Hence, it is important to standardize queen rearing methodology in A. cerana indica in order to multiply a large number of queens and supply superior-character queens to the beekeepers in India

Studies were undertaken to assess the effects of amino acids on the food intake, silk gland, and protein content of silkworm, Bombyx mori L. Three amino acids, namely Glycine, Alanine and Serine at various concentrations viz., 10, 20, 50, 100 and 200 ppm were used for the investigations. The silkworm larvae were supplemented with amino acids, once daily in the morning from first day of fifth instar to spinning. Experimental results showed that irrespective of the concentrations studied, the amino acids had positive influence on the food intake, silk gland, and protein content of silkworms. Though all the treatments were found to significantly increase different parameters namely co-efficient of food utilization, weight and length of silk gland, protein content in silk gland, haemolymph and cocoon the enhancement was highest at concentration of 10 ppm, 100 ppm and 100 ppm, respectively in Glycine, Alanine and Serine

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Tamil Nadu Veterinary and Animal Sciences University, Chennai, to study the effect of irrigation water and nutrients on the yield and nutrient uptake of fodder cowpea. The experiment consisted of two factors with irrigation water and nutrients with three and four treatments respectively. The results of the experiment indicated that the application of sewage water along with recommended dose of farm yard manure and inorganic nutrients enhanced the growth attributes and yield of fodder cowpea. The leaf stem ratio was found higher with the application of sewage water and the application of farm yard manure and inorganic nutrients. The increase in yield of cowpea with higher nutrient content resulted in increased nitrogen, phosphorous and potassium uptake by fodder cowpea. The post harvest samples have shown that application of sewage water and nutrients to the soil had positively resulted in the uptake of nutrients by fodder cowpea. Application of sewage water along with the recommended dose of nutrients resulted in 22.3 percentage of yield compared to application of irrigation water and without nutrient application.

Crop development and yield are both influenced by the weather. A generic agro-climatic yield prediction model for grape is created and analytically solved in this research. In the field of mathematical biology, this model is valuable for research scholars, faculty members, and academics. To acquire the final form of the yield prediction model, an asymptotic analysis is performed. Climate, disease, and grape yield are all dependent parameters in the model creation process. Independent characteristics include infection rate, disease incidence, seasonality rate, and removal rate of grape production per harvest period. The model is also examined, with parameters estimated using field data from GRS during the period 2015-2021.On concentration curves, the impacts of various parameters are discussed. This model's stability analysis is also explained. The obtained analytical solution is found to be in satisfactory agreement with the numerical and stability studies

India has the second highest area under sugarcane cultivation, next to Brazil. Sugarcane is cultivated 4.7 million ha with the productivity of 72 tonnes/ha. Tamil Nadu ranks first in sugarcane productivity in the country, recording an average of more than 100 tonne/ha. Manual sugarcane sett cutting method is time consuming, expensive, and involves human drudgery. To reduce human drudgery and time involved in the operation, the sugarcane sett cutter has developed with 3.7 kW diesel engine, basic frame, belt clutch assembly, power transmission assembly, serrated discs, bearings, and safety cover. The rotational speed of 1100 rev./min, serrated disc 160 mm diameter and 45˚ cutting angle were optimized based on the number of setts cut per hour, fissures in setts and germination percentage. The cost of sugarcane sett cutting for planting by the machine comes to Rs. 91/h, including depreciation, interest, fuel, lubricating oil, repairs and maintenance and operators’ wages. The machine could cut 5940 setts/h. The operational cost of the machine comes to Rs. 16 / 1000 setts and Rs. 1200/ha. Then, it observed germination was 92 percent. The cost of the machine is Rs. 27,000/-.

The millets or "Nutri-cereals" or superfoods, are highly nutritious and offer various health benefits. Despite their advantages, millet production has declined in India from 2010-11 to 2020-21 at -0.94 Compound Annual Growth Rate (CAGR). This study focuses on assessing the awareness, analyzing the consumption pattern and the factors influencing the consumption of millet products among college students in the YSR (Kadapa) district, Andhra Pradesh. The primary data for the study was gathered through structured interviews with 120 college students from four colleges in the study area. The respondents' demographic, economic, social, psychographic, and behavioral features were analyzed. The study revealed that most respondents (94.17 per cent) were aware of millet based products, and 80.83 per cent respondents were aware through word of mouth from family and friends. Products made with Ragi millet were the most consumed millet products. The health and nutritional benefits was the key factor influencing millet product consumption. The findings can assist businesses in effectively marketing their millet-based products.

Farm mechanization accelerates faster agricultural growth through the efficient use of machines by ensuring the timeliness of agricultural operations, reducing the cost of operation, and by reducing human drudgery. Farm machinery ownership and operating costs represent a substantial portion of total crop production expenditure. Cost economics becomes important for farm machinery managers to control the machinery costs per hectare. The manual procedure of determining the cost economics of agricultural machinery is a time-consuming process and finally making a smart decision whether to buy a farm machine or to go for custom hiring is a cumbersome process. The web application was designed for naive users to help the users in making the decision. The user is asked to enter the basic data pertaining to the farm machine, and the software decides whether to acquire the farm machine or to go for custom hiring. The cost of operating a farm machine can be computed with ease by using the web application. Further, the break-even-point, payback period and benefit-cost ratio can also be determined with a single click

A field experiment was conducted to determine the effect of zinc fortification on growth attributes, yield attributes and soil-available nutrients of babycorn. The treatments comprised of T1: control, T2: ZnSO4 at 25 kg ha-1 as soil application, T3: ZnSO4 at 37.5 kg ha-1 as soil application, T4: Foliar spray at 0.5% on 20 and 40 DAS, T5: Foliar spray at 1.0% on 20 and 40 DAS, T6: T2+T4, T7: T2+ T5, T8: T3+ T4, T9: T3+ T5. Growth parameters viz., plant population, leaf area index, days to first tasseling, days to first cob initiation and days to first harvest were significantly influenced by combined application of ZnSO4 to soil @ 37.5 kg ha-1 with foliar spray @ 1.0% on 20 DAS and 40 DAS. Dry matter production of babycorn was significantly higher in soil application of ZnSO4 @ 37.5 kg ha-1 with foliar spray at 0.5% on 20 and 40 DAS. Increased yield attributes such as number of cobs/plant, cob and corn length, cob and corn weight, cob and corn girth were observed higher with combined application of ZnSO4 @ 37.5 kg ha-1 to soil with foliar spray @ 0.5% at 20 and 40 DAS. Soil available nutrient status of NPK was not significantly influenced by Zn fertilization. However, higher availability of zinc nutrient after harvest of the crop was obtained with application of ZnSO4 @ 37.5 kg ha-1 in soil with foliar spray of 0.5% at 20 and 40 DAS.
