This research is a randomized complete block design with four treatments (1- control (without using any fertilizer) 2- humic acid 50% (brand name bishumic) per hectare, 1000 kg (100 grams) per plot with dimensions of 1 m x 1 m) 3- Humic acid 40% (with the brand name Humi Green) along with 5% nitrogen, 2% phosphorus, 2% potash per hectare 1000 kg (100 grams per plot with dimensions of 1 m x 1 m) 4- 40% humic acid (with the brand name Humic Plus) along with 5% nitrogen, 5% phosphorus, 2% iron and 0.25% copper per hectare 1000 kg (100 grams per plot with dimensions 1 m x 1 m) ) in four repetitions, a total of 16 experimental plots were performed. After determining the location of each treatment, except for the control treatment, half of the determined amount of fertilizer was added to each plot (50 grams for each plot), then one irrigation was done and the seedlings were planted. The results showed that the amount of essential oil in the humic plus fertilizer treatment increased due to the increase in plant growth and the subsequent increase in dry matter. The amount of absorption of micronutrient elements such as iron, copper, zinc and manganese also increased. Manuscript profile -

Therefore, the aim of this study is the biosynthesis of silver nanoparticles using the aqueous extract of native Ajowan seeds and its effect against Onion bacterial rot. In this research, first, isolation and identification of pathogenic bacteria from different areas of Jiroft city was done. Then the biosynthesis of Ag NPs was carried out by aqueous extract of Ajowan seeds and the their effects against Pectobacterium were investigated in laboratory and warehouse conditions. A total of 12 bacterial isolates, N3 isolate from Anbarabad region had the highest pathogenicity. The biosynthesis of Ag NPs was confirmed by observing the date color after 15 minutes in the dark at room temperature and the ultraviolet spectrometer showed that the surface plasmon resonance is at 420 nm. The growth inhibition rate of biosynthesized Ag NPs and Mancozeb poison each alone and their combination against Pectobacterium in vitro were 62.45, 100 and 88.67%, respectively. Also, Ag NPs and Mancozeb each alone within three months and combining them together within two months caused 100% shelf life of onions in storage. However, the combination of biosynthesized Ag NPs and Mancozeb together with Pectobacterium had 100% inhibition in the first and second month and 85% in the third month against bacterial rot disease. Therefore, the results showed that biosynthesized Ag NPs were effective in controlling pathogenic bacteria and can replace agricultural toxins. Manuscript profile -

This plant is in the third place after rice and wheat in terms of consumption in the world, for this reason this plant is considered as one of the plants that protect food security. Low soil fertility is the most important limitation for potato production. Farmers should deal with this problem by using mineral fertilizers that improve soil productivity. Using the right amount of NP fertilizer is the main factor in potato production. A field experiment was conducted in the main cropping season of 2022 and 2023 to investigate the optimal amount of NP on potato tuber yield in Jiroft region. The treatments including four levels of nitrogen (0, 46, 92, 138 kg/ha) and three levels of phosphorus (0, 46, 69 kg/ha) were factorially combined in a randomized complete block design with three replications. The results of the study showed that the use of 92 kg of nitrogen per hectare is recommended in Jiroft. Even if P application does not affect potato tuber yield, 23 kg/ha of P fertilizer should be applied to maintain soil fertility. Manuscript profile -

Plants were grown in 2Kg pots and subjected to three salinity(NaCl) treatmentsand (1.2 ,8.9 and 16.7ds/m) in a greenhouse at jiroft. The expriment was done in a factorial with complete randomized design and three replications.During vegetative growth shoot Na+ ,K+ contents were measured for all genotypes.Plant traits including the plant height ,length of spikes ,number of spikes per plant ,fresh weight and dry matter and grain yield per plant were also measured.There was a very wide variation in salt tolerance of the genotypes with regard to Na+ and K+ contents.In general tolerant genotypes with better agronomic performance contained lower Na and a higher amount of K to non-tolerant ones and these two parameters were significantly and negatively correlated(r=-0.71,p<0.01).

Biotechnology, often referred to as biotech, has existed since the beginning of civilization with the domestication of plants, animals and the discovery of fermentation. Biotechnology is a broad science that uses modern technologies to make biological processes, organisms, cells, or cell components. New clinical tools, industry, and products developed by biotechnologists are useful in research, agriculture, and other major fields. Biotechnology is as old as civilization. The food you buy and the pets you love? Using artificial selection for crops, domesticated animals, and other species, you can thank our distant ancestors for starting the agricultural revolution. The potential of biotechnology was exploited when Alexander Fleming discovered antibiotics and when Edward Jenner invented vaccines. And of course, without the fermentation mechanisms that gave us beer, wine, and cheese, modern society would be unimaginable. This article summarizes some of the applications of biotechnology for Example Animal Feed, Reproduction in Aquaculture, Pest Resistant Crops, Drought Resistant Crops, Biofuel, Vaccine evelopment, Fermentation, Enzymesin food and agriculture.

In this research, Non-free spawning preference, the length of the prepubertal growth period, and the mortality rate before the maturity of this pest on tomato cultivars including Rio Grand, Ergon, Early Urbana I, and Early Urbana II were investigated under greenhouse conditions. The experiments were designed in a completely randomized block design. The results showed that there is a significant difference at the level of five percent in terms of spawning. The lowest and highest number of eggs per unit of leaf area were observed in Early urbana II and Ergon cultivars, respectively. The results showed that the effect of the host cultivar on the length of the developmental and mortality period of the embryonic and pupal period is not significant, but it is significant on the length of the developmental and mortality period of the nymph period and prepubertal (egg to complete insect). The highest length of the growth period of nymph and prepubertal (egg to complete insect) was recorded on the Early urbana II cultivar and the lowest value of the above parameters was recorded on the Ergon cultivar. The highest losses of the nymph stage and prepubertal (egg to complete insect) were observed on the Early urbana II cultivar and the lowest value of these parameters was observed on the Ergon cultivar. Therefore, the Early urbana II cultivar is more unfavorable to B. tabaci than the other cultivars, and it is a desirable attitude to prioritize planting it in the pests management strategy to lessen the damage caused by the B. tabaci.
