Abstract

Vitamin C is an important component in plants and humans. Kiwifruit was a valuable fruit with characteristic taste and flavor and high vitamin C contents. To date no studies have investigated the formation and accumulation mechanism on vitamin C in ‘Xuxiang’ kiwifruit. To elucidate the mechanism by which vitamin C accumulated of ‘Xuxiang’, we systematically investigated the gene expression profiles of the L-galactose pathway as well as the ascorbate–glutathione cycle. Our results showed that the content of vitamin C was high in “Xuxiang’ early fruit development, and then it decreased 50% during fruit division. The content of vitamin C kept about 80 mg/ 100 gwhen fruit developed completely. L-galactose pathway was an important route for vitamin C accumulation, which PGI1, PMM1, GMP1, GME1, GGP1, GDH1 and GalLDH1 were all important genes consist with vitamin C content.

Abstract

The aims of the study were to determine the effect of arbuscular mycorrhizal inoculation and SP-36 fertilizer and their interaction on the growth and yield of oil palm seedlings of the DxP PPKS 540 variety and to obtain the appropriate dose of mycorrhizal biofertilizer and SP-36 fertilizer for the growth of oil palm seedlings at the pre-nursery stage.The research was carried out from April 2020 to August 2020.The place of research was held on Jl. Rapak Indah, Karang Asam Ilir urban Village, Sungai Kunjang sub District, Samarinda City, East Kalimantan Province.The materials used in this study were DxP PPKS 540, Fungi Mycorrhizal, SP 36 Fertilizer, Dithane M-45, polybag size 22x14 cm and paranet.The tools used in this study were arco carts, soil pH measuring instruments, hoes, soil loosening tools, writing instruments, analytics, and gembor.The study used a completely randomized design (CRD) in a 5x4 factorial experiment, with two treatment factors and repeated 4 times.Mycorrhizal dose factor (M) which consists of 5 levels, namely: no mycorrhizal application or control (m ); 0 2.5 gpolybag-1 (m ); 5.0 gpolybag-1 (m ); 7.5 gpolybag-1 (m ) and 10.0 gpolybag-1 (m ) Dosage factor SP 36 (P ) 1 2 3 4 consisting of 4 levels, namely: no SP 36 fertilizer application of control (p ); 1.0 gpolybag-1 (p ); 1.5 gpolybag-1 (p ); and 0 1 2 2.0 gpolybag-1 (p ).Research activities, namely: preparation of planting media, treatment of microzia, preparation of 3 sprouts, planting of seedling, treatment of SP-36 fertilizer, maintenance of seedlings (watering, weeding, and loosening of planting media), and data collection.Data collection is analysis of soil chemical properties in the laboratory, seedling height, stem diameter, number of leaves at aged 1, 2, 3 months after planting and root length at 4 months after planting.Data analysis was carried out by analysis of variance, if the results of variance were significantly different (F-count > F-table 5%) or very significantly different (F-count > F-table 1%), then a further test was carried outwith the Least Significant Difference test at 5% level.The results showed that (1) Arbuscular mycorrhizal application had no significant effect on the growth in height, stem diameter, number of seedling leaves at the age of 1, 2, and 3 months after planting, and root length of seedlings at 4 months after planting;(2) application of SP-36 fertilizer had a significant to very significant effect on the height growth at 1, 2, and 3 months after planting, seedling diameter at 1 month after planting, number of leaves at 1 and 3 months after planting, and root length. seedlings at the age of 4 months after planting.Application of SP-36 fertilizer at a dose of 1.5 – 2.0 gplant-1 tends to inhibit the growth of oil palm seedlings in the pre-nursery phase;and (3) there was no interaction between mycorrhizal treatment and SP-36 fertilizer treatment on the growth of oil palm seedlings in the pre-nursery phase.

Abstract

Plants can capture CO 2 from the air and sequester it in the leaves through photosynthesis. Even additional carbon sequestration could be achieved by allowing higher cropping intensity on the same piece of land in a single cropping season. There is a growing demand that agricultural developers and practitioners consider carbon farming in the design of cropping patterns in order to intensify carbon sequestration and trade it as a carbon credit for extra financial benefits. However, adopting a sustainable carbon farming while respecting the farmer’sneeded income and food security may seem a difficult task. Nevertheless, this fundamental challenge can be addressed using an optimization technique such as simplex linear programming (SLP). The Microsoft Excel program includes a SLP solver tool, which can easily be accessed from the Excel program Data menu after activating the Add-Ins part of the Excel Options. In this study, seven scenarios were developed to be analyzed by the SLP to investigate the various options of adopting carbon farming into the cropping pattern while maximizing either the individual or the combined benefits of farmer’sincome and farmer’sfood security for the Mekabo irrigation scheme in Ethiopia. The result shows that the optimized cropping pattern in scenario seven best satisfies the farmer’sfood security and farmer’sincome while still stimulating extra financial benefits from carbon farming. Alley cropping, multi-species-cover cropping, and no-till planting in scenario seven could encourage the highest rate of additional carbon sequestration so it could better contribute to the alleviation of global warming. This paper will discuss how the SLP is developed and applied leading to the attainment of an optimized cropping pattern while the financial benefit is maximized.

Abstract

The current investigation was conducted in the Forest Nursery, SHUATS, Prayagraj, U.P., between 2021 and 2022. Based on afield experiment conducted on the effect of Organic and Inorganic Nutrient Sources on Growth and Yield of Cotton (Gossypium hirsutum L.) Under Teak (Tectona Grandis) Based Agroforestry System, it was concluded that the treatment T7 (NPK 100 percent) was found superior among that treatment under teak based Agroforestry system. It was also observed that maximum Cotton Yield (i.e., 24.16t/ha) In terms of economic feasibility performance, treatment T7 (NPK 100 percent) demonstrated the highest benefit-cost ratio (i.e., 1.67).

Abstract

The present study was conducted indifferent villages of block Basar, Leparada district, Arunachal Pradesh. A total of 120 respondents were selected randomly. The data were collected by the researcher using pre-structured interview. The finding shows that the majority of respondent were practicing Agrisilviculture system and Agrosilvopastoral System (Home garden).
