Increase in agricultural productivity yields is strongly influenced by climate change. Extreme climate change has resulted in crop failure due to land drought and flooding. The existence of this incident provides an opportunity to decrease the welfare of farmers, especially plantation farmers in Indonesia. The purpose of this study was to determine the effect of temperature on the welfare of plantation farmers in Indonesia. The data used in this study was sourced from the 2018 National Socio-Economic Survey (SUSENAS) data, with a total of 66,754 households in Indonesia. The analytical method used is Ordinary Least Square (OLS). The results of this study indicate that an increase in temperature causes drought, and has an impact on decreasing agricultural productivity. The decrease in the production of agricultural products certainly reduces the income of farmers, which results in a decrease in the level of welfare of farmers. Government policies in terms of climate engineering are needed, as well as assistance programs for farmers to maintain the welfare of farmers.</p> Faradiba Faradiba ##submission.copyrightStatement## Wed, 08 Jun 2022 00:00:00 +0000 Bioactivity of Leaf Extract of Phyllantus amarus against Fungal Pathogens Associated with Sweet Orange Rot Disease <p>This study was carried out to determine disease incidence and control of fungal pathogens associated with rot of sweet orange using <em>Phyllantus amarus</em> leaf extract. Forty sweet oranges (<em>Citrus sinensis</em> var. Valencia) were collected from the markets and taken to the laboratory. Isolation and identification of the fungi were carried out using standard procedures and the efficacy of the leaf extracts of <em>Phyllantus amarus </em>was determined on the isolated fungi. The result of this study showed that four pathogens (<em>Aspergillus niger, Aspergillus flavus, Penicillum expansum </em>and <em>Rhizopus stolonifer</em>) were identified to be associated with the rot. Rot incidence was upto of 35%. Pathogenicity confirmed the characteristic features similar to the original diseased samples. The effect of the leaf extract of <em>Phyllantus amarus </em>on the isolated fungi shows that the rate of inhibition increases with increase in concentration of the <em>P. amarus</em> extract, The <em>P. amarus</em> extract was effective against<em> A. flavus</em> had the highest zone of inhibition (10.667). The inhibition zone was lesser for <em>R. stolonifer</em> among the pathogens (8.333). Sweet orange should be consumed after harvest or can be stored in refrigerator for period of 1=2 weeks. The fruit should be discarded if&nbsp; any alteration in color or taste of the fruit is noticed as this can be hazardous to human health.&nbsp;&nbsp;&nbsp;</p> C. S. Yusuf, N. N. Zakawa, D. Timon, T.

To evaluate the effects of different fertilizer types in the control of root knot nematode of sweet potato. The experiment was laid out in a randomized complete block design (RCBD). The treatments were Liquid fertilizer (Super gro) and poultry dropping and control which were replicated three times. Before the treatments were applied, soil samples were collected for nematode extraction and the nematodes were extracted in the laboratory using the modified Bearmann tray technique. Super gro and geese droppings were applied at 2 weeks interval and 4 weeks interval. The results show a significant (p&lt;0.05) reduction of root gall index, significant increase in root length, weight of roots and number of roots on the plots treated with fertilizer. This research work recommends the application of poultry droppings for the management of root knot nematode in sweet potato (<em>Ipomoea batatas</em>).</p> I. O. Adepoju, J. I. Oluwatayo, O.V.

Mushroom cultivation is a low-cost, high-return activity that has proven to be an additional source of income. Because the vegetarian population in our country's urban centers has adopted mushrooms in their diet due to their nutritious worth, mushroom producers in nearby rural areas have an excellent market for selling their products quickly and at a reasonable price. As a result, the mushroom benefits both producers and consumers, earning it the title of super food.&nbsp; Mushroom production can also be used to empower rural people, offer additional income for agricultural families, and address the issue of rural people's nutritional needs. Rural unemployed people are the most productive workforce in the economy, necessitating efforts to enhance and strengthen their socioeconomic condition. Mushroom farming all year can produce revenue from the sale of spawns as well as the sale of fresh mushrooms in a sustainable manner by using farm by-products as a raw material.</p> Satish Chand, Bihari Singh ##submission.copyrightStatement## Fri, 10 Jun 2022 00:00:00 +0000
