Fertility Alteration and Gene Action Analysis for Yield Characteristics in Two-Line System Hybrid Rice (Oryza sativa L)

Paper ID- AMA-08-02-2023-12001

Combining ability and gene action of the main agronomic and yield traits in Egyptian PTGMS (females) and Egyptian Japonica (EJGSR) and Indica Japonica Green Super Rice (EIJGSR) lines (male testers) were studied. The combining ability, gene action, and genetic parameters of ten main traits were analyzed by Line x Tester using five PTGMS lines and six male testers. The altered fertility of the tested lines was investigated at different periods. All traits are mainly controlled by the general combining ability of the parents. For all traits except spikelets panicle-1, the mean square value difference of the L x T (SCA) of the tested combinations was extremely significant. The estimated values of variance due to GCA were higher than that due to SCA for all agronomic and yield traits and its components. The expected value of GCA for male testers K2g (M) was higher than female PTGMS lines K2g (F) for all traits. The ratio of K2gca/K2sca was more than unity for all traits indicated the additive gene action is playing big role in the inheritance of these traits. EPTGMS 85 was the best combiner of female lines for grain yield. The testers, EIJGSR (F) 73, EIJGSR (F) 62 and Sakha Super 301, were the best general combiners among testers for grain yield and most of studied traits. Seven super hybrid rice combinations were the best, giving significantly positive (desirable) estimates of the SCA effect on grain yield (t ha-1). The highest estimates were obtained for EPTGMS85/Sakha super 300), EPTGMS20/EJGSR179 and EPTGMS34/Sakha super 300.

Laboratory incubation experiment for assessing the suitability of cement kiln dust for soil application

Paper ID- AMA-07-02-2023-12000

In order to develop an integrated solid waste management strategy for cement factory waste (Cement kiln dust (CKD)), a lab experiment was conducted to study the influence of CKD on soil properties for a duration of 60 days in red (Irugur soil series) and back soils. The results of the study revealed that the application of CKD alone at higher rates (10 t ha-1) had negatively influenced the soil bulk density (increased from 1.45 to 1.48 and 1.40 to 1.47 g/cc in red sandy soil (Irugur soil series) and black cotton soil (Periyanaickenpalayam series), respectively) while the application of CKD at 5 tonnes per hectare along with coir-pith 10 t ha 1 improved the soil bulk density in both the soils (decreased from 1.45 to 1.36 and 1.40 to 1.36 g/cc in red sandy soil (Irugur soil series) and black cotton soil (Periyanaickenpalayam series), respectively). Soil pH was found to increase in red soil (Irugur soil series) (from 7.18 to 8.72) whereas it decreased in black cotton soil (Periyanaickenpalayam series) (from 9.51 to 8.63) due to the application of CKD. Soil salinity was increased in both soils (from 0.19 to 0.99 and 0.35 to 1.15 dS m-1 in red sandy (Irugur soil series) and black cotton soil (Periyanaickenpalayam series), respectively) due to the application of CKD at 10 tonnes per ha of press-mud at the rate of 5 t ha-1. Available N of the soil decreased from 157 t ha-1 to 151 ha 1 ¬in red sandy soil (Irugur soil series) while in black cotton soil (Periyanaickenpalayam series), it does not show any significant difference. The soil available P content in both soils recorded no significant difference. Soil NH4OAc K contents were increased (from 224 to 426 and 352 to 560 t ha) due to the application of CKD at the rate of 10 t ha-1. Application of along with press-mud 5 tonnes ha-1. Soil organic carbon was decreased due to the application of CKD at 10 t ha-1 was on par with the application of CKD at the rate of 5 tonnes per ha. Application of CKD at the rate of 5 t ha-1 along with the application of a recommended dose of FYM increased the soil organic carbon in both soils. The microbial properties of the soil viz., total bacteria, fungi, and, actinomycetes population were found to decrease due to the application of CKD at 10 t ha 1 in both soils. Similarly, the application of CKD at 5 t ha 1 along with green manure at 6.25 t ha-1 increased the bacteria, fungal, and, actinomycetes population. The result indicated that CKD can be recycled in agriculture at a quantity below 5 tonnes per ha with organic amendments without any adverse effect on soil properties.

Agricultural Expansion in Saudi Arabia: A Challenging Present and Demanding Prospect

Paper ID- AMA-07-02-2023-11999

Even though the environmental conditions for farming are subpar in the Kingdom of Saudi Arabia, the agriculture sector is still given considerable support. With the help of its five-year development plans, the state has been working hard to improve its agricultural sector and thereby secure the state's food security. Farmers were able to increase agricultural productivity and become somewhat self-sufficient as a result of the government's favourable policies and the extension service's expert advice. Wheat, dates, watermelons, chicken, fresh eggs, and milk are only some of the goods that the state is now exporting, according to the state's abundant published material. Wheat, sorghum, barley, and millet are only a few of the cereals grown in the kingdom in areas with plentiful water. Besides tomatoes and watermelons, eggplants, potatoes, cucumbers, and onions are also cultivated. Date-palm, citrus, and grape output have all shown positive responses. The ultimate goal of any agricultural effort is to ensure that people will never go hungry again. The country fulfilled its agricultural potential in order to feed its growing population, but this came at the expense of excessive use of its natural resources. A new initiative to grow crops with lower water requirements has been launched by the government. There is widespread agreement among policymakers, academics, and scientists that excessive water use is not viable in the long run. The environment must be protected while a sustainable equilibrium is kept between agricultural output and the use of its resources, especially water. Due to the current state of affairs, the job of Agricultural Extension is more difficult and time-consuming than ever before. Since the farms are overseen by foreign workers who don't speak Arabic or English, the state's extension activity is particularly challenging and fraught with complications. To further the cause of environmentally responsible farming in Saudi Arabia, researchers at King Saud University (KSU) established an Extension Centre.

SCREENING OF GROUNDNUT VARIETIES/ GENOTYPES FOR RESISTANCE AGAINST APHID APHIS CRACCIVORA AND LEAFHOPPER EMPOASCA KERRI

Paper ID- AMA-05-02-2023-11995

The field experiment was conducted for two consecutive years 2020 and 2021 during the Kharif, season at Agronomy Farm, S.K.N. College of Agriculture, Jobner (Rajasthan). Out of fifteen genotypes of groundnut screened against aphid and leafhopper four genotypes viz., RG-632-1, RG-559-3, Girnar-4 and RG-633 were categorized as least susceptible against both the insect. Whereas, RG-622-5, RG-382, RG-638, RG-628, RG-621, TG-37-A and RG-639 as moderately susceptible and RG-624, RG-425, RG-510 and RG-578 as highly susceptible to aphid infestation. Eight genotypes viz., RG-382, RG-638, RG-622-5, RG-628, TG-37-A, RG-639, RG-425 and RG-621 were moderately susceptible and three genotypes viz., RG-624, RG-510 and RG-578 were highly susceptible to leafhopper infestations.

An experimental comparison of meter calibration used in a photovoltaic water pumping system installed in an arid environment

Paper ID- AMA-05-02-2023-11992

Energy and water are crucial for humans in all their activities. In rural areas, irrigation is a surviving key where sustainable approaches like solar water pumping systems are required to meet this demand. One of the crucial challenges in the hydraulic field is the flow rate measurement with high accuracy. The exact estimation of the water flow rate pumped using a solar photovoltaic water pumping system is essential to evaluate the system's performance. This paper presents an analytical method to study a comparative analysis of the results of the system measurement errors. The experimental data are collected from our pumping system located in Adrar city (Algeria). The performance is analyzed using the measured water flow rate data using three different meters, one ultrasonic and two turbine meters, where a turbine meter is used as a standard meter. The test was done in May 2019.
