Abstract

Correlation coefficient and path analysis were computed between yield and yield attributing trait among twenty genotypes of wheat. The research was conducted during winter season of 2020/2021 in the agronomic field of the Institute of Agriculture and Animal Science (IAAS), Bhairahawa, Nepal to identify the traits which influence the positive and negative relation to grain yield. Twenty genotypes of wheat were sown on 24th December 2020 on alpha lattice design with two replications. It has been found that under heat stress, DTB, DTH, DTM, CLC, PH, NGPS show a non-significant positive correlation with GY. Similarly ET shows a highly significant positive correlation to GY. However, SL, SW, TKW have a non-significant negative correlation with GY. In path analysis, DTM and ET have a positive direct effect on GY and DTH, SL, CLC and NGPS have an indirect effect on GY. Hence, the ET and DTM can be used to select wheat genotype for breeding purpose and studies to improve yield of genotypes under heat stress condition.

Abstract

Chicken is one of the mainstay commodities and is a very popular food ingredient by various groups of society. Chicken consists of carcass and non-carcass parts, all of which are almost utilized. A study conducted on as many as 36 Chickens to see differences in patterns of growth and development of non-carcass organs of different sexes and ages. Data analysis was performed using the allometric equation Huxley Y = aX The results showed that the coefficient of non-carcass growth and development of non-carcasses of male and female Chickens was significantly different from one which meant that it had time to cook development premature compared to overall body growth and growth patterns of non-carcass organ growth of Chickens both in males and females at the age of 0 - 5 weeks showed no significant difference. It can be said that male and female broiler chickens aged up to 5 weeks have the same pattern of growth and development of non-carcass organs and earlier than the overall body growth.

Abstract

Agricultural extension agents are agents of change who are directly related to farmers The purpose of the extension is to change the behavior of farmers in terms of knowledge, attitudes, and skills so that farmers have a more prosperous life. Rice farmers in West Tojo District carry out farming activities that still rely on hereditary habits, causing farmers to lack the capacity to run food crop businesses, both technically in cultivation, harvesting, and marketing. The objectives of the study are (1) to determine the level of capacity of rice farmers in Kabalo Village Tojo Una-Una District and, (2) to determine the effect of the role of extension agents on increasing the capacity of rice farmers in Kabalo Village Tojo Una-Una District. This research was conducted from March 2020 to August 2020 in Kabalo Village West Tojo District Tojo Una-Una Regency. This study used a population sample of 56 rice farmers. Based on the results of this study, the role of agricultural extension agents had an effect on the success rate of rice farmers in Kabalo Village. Through increasing the role of extension workers, both facilitators, motivators, mediators, advisors, and communicators, could increase the capacity of farmers in managing capital, utilizing technology, labor, and marketing processes that benefit farmers.

Abstract

The present research attempted to address cost inefficiency of USAID MARKETS II smallholder farmers in Nigeria’s Kano State using farm survey data obtained from 189 farmers through a multi-stage sampling technique. The farm survey data were elicited viz. well-structured questionnaire coupled with interview schedule during the 2018 cropping season. The collected data were analyzed using both descriptive and inferential statistics- stochastic cost frontier function. The empirical evidence showed that none of the technical unit was cost efficient and this owed majorly to extension gap given its interwoven link with risk inducing factors. Besides, only 57.7%, marginally above half of the sampled technical units were fairly cost efficient i.e. close to the optimum minimum cost preferred for the production process. On the average, a technical unit wasted 14.7% of its actual incurred cost which translates to N1100 ($3.7) relative to the best practiced farmers facing the same technology and producing the same output. Therefore, since the farmers still have the room to eliminate the extra cost incurred, the study advice the program to explore further the advisory services offered to the farmers, thus addressing the extension gap that inhibited the farmers’ cost efficiency. The sustainability of the project in the near future in the absence of the advisory services especially farmer-2-farmer extension services if not explored is unlikely.

Abstract

Root rot in brinjal is one of the most important problems. In the present research, five different fungicides; Mancozeb, Copper oxychloride, Hexaconazole, Metalaxyl+Mancozeb, and Carbendazim, at 100 ppm were evaluated for their efficacy against the causative agent of this disease, Fusarium solani, In-vitro. The experiment was carried out in Completely Randomized Design with seven replications. Our result shows the difference in the efficacy of all tested fungicide against this pathogen. The application of Carbendazim at 100 ppm gave the highest inhibition of mycelium growth (100%) followed by Mancozeb (85.08%) and Metalaxyl+Mancozeb (64.3%) (at the same dose) on the 7th day of incubation suggesting Carbendazim (100 ppm) as a better one to use for the management of F. solani.

Abstract

Today, due to the rapidly increasing world population and urbanization, the amount of water is increasing exponentially in areas such as drinking, irrigation, energy, industry, etc. There is a great increase in the use of water in agriculture, especially due to the food needs of human beings. For this reason, human beings need water; They obtain water almost everywhere from above ground (springs, dams, ponds) and underground (drilling wells) water sources. Usage of groundwater is quite common in the plains, where surface water resources are insufficient. This situation; While increasing the use of pesticides and fertilizers for agricultural purposes due to irrigation, it also creates the risk of contamination of groundwater. In this study; contamination potential of groundwater in Erzin Plain was determined using Geography Information System (GIS)-based DRASTIC model. Seasonal and annual field sensitivity levels were determined by integrating current land use into this model. Accordingly, in the dry seasons of August-2006, November-2006, while the Mediterranean coast has high EC values in the vicinity of the Mediterranean coast, the area around the resort sites and the settlement area, the mountainous areas, the north of the plain and the west of Gokdere have low EC values. It has the lowest EC values by decreasing towards the north and northeast and other parts of the plain. In the study area; Although NO3 concentration varies seasonally, it is especially high in citrus growing segments with high permeability. On this change; Factors such as rainfall recharge, evaporation effect in the dry period, irrigation water recharge with the effect of land use, and the depth of groundwater depending on topography played an important role.

Abstract

Utilization of maggot as a substitute for protein source feed ingredients can be a solution to overcome the high cost of feed. However, the inappropriate growth media caused the growth of maggots to be inhibited. Palm kernel cake, vegetable and fruit waste have high nutritional content which has the potential as a medium for growing maggots. The purpose of this study was to determine the best growth of maggot on various growing media. The treatments given in this study were P0A = 100% palm kernel cake; P0B = 100% vegetable and fruit waste; P1 = palm kernel cake 75% + vegetable and fruit waste 25%; P2 = palm kernel cake 50% + vegetable and fruit waste 50%; P3 = palm kernel cake 25% + vegetable and fruit waste 75%. The results showed that the use of growing media from mixing 25% palm kernel cake + 75% vegetable and fruit waste (P3) gave better results as a growth medium for the effectiveness of the growth of maggot. This is due to the nutritional needs of maggots for its growth have been met from the nutritional content and organic matter available in optimum quantities in the growing media. It was concluded that the growing media from palm kernel cake with vegetable and fruit waste had effectiveness in increasing the growth of maggot.

Abstract

The main objective of this research is to compare the amino acid and proximate compositions of raw and roasted maize samples. Complete randomized experimental design with triplicates replications was applied. From the analysis, we were able to obtain the following values: total carbohydrates (78.28-79.85 percent), crude protein (7.32-7.05 percent), crude fat (2.70-2.20 percent), crude fiber (2.40-2.10 percent) and ash (2.10-2.50 percent) for both raw and roasted maize seeds. Prolonged exposure to the heat from roasting altered the amino acid content as obtained from the result. The concentration of amino acids in the seeds was reduced by the heat effect. The highest concentration of leucine was contained in seeds, with a value of 1.30 g/16 g N and 0.95 g/16 g N in the case of the raw and roasted seeds, respectively. Lysine and tryptophan concentrations were low, but they contain equal quantities of amino acids containing sulphur, which are methionine and cystine.

Abstract

Three experiments were conducted using three different stages of fruit maturity (100, 105, and 110 DAFI or days after flower induction) of ‘Carabao’ mangoes harvested from the same set of trees. Fruits harvested were applied with 1-MCP [(dosage:0.5 µL/L) via gas exposure for 20 hours and spraying], and ethephon (dipping at 1ml/L of H2O) applied singly or in combination. Mangoes were then stored in ambient room conditions [29.2±1.6°C, 69.88±4.0% relative humidity (RH)]. Mango fruits with 1-MCP treatment applied through gas exposure at 0.5 µL/L consistently delayed the peel color change, firmness, and weight loss of harvested fruits at 100, 105 and 110 DAFI. These fruits held its shelf life for 15 (100 DAFI), 12 (105 DAFI) and 9 (110 DAFI) days compared to control with 12, 10 and 8 days respectively. Furthermore, all treatments showed varied effects on the visual quality of fruits regardless of its maturity. It also appeared that fruits at 105 DAFI treated with ethephon alone have better taste while other organoleptic attributes, chemical properties (TSS, TTA and pH), as well as the disease incidence and severity were found to be comparable. This further proved that 1-MCP delays ripening of fruits but could not prevent disease occurrence.
