Date palms are dioecious plants and require artificial pollination to reach an economic yield. Despite the development in artificial pollination methods, hand pollination is still the most used technique in North African countries. However, the practices remain not well controlled particularly in terms of pollen quality. Therefore, enormous pollen quantity was used for pollination. In this study, the effect of four pollen densities was recorded, which represent 67, 87 and 97% lower than the control pollen quantity. The effect was observed on fruit set, retention and quality; seed germination; and plantlets vigor. The fruit size and weight (fresh and dry matter), moisture content, and yield were significantly reduced with the decreasing pollen density. The fruit set was not influenced by pollen density in maturation stages; <i>kemari, khalal</i> and <i>rutab</i>. However, fruit retention decreased significantly by pollen density. The seed germination was reduced significantly; while, there was no effect on seedling growth between all pollen treatments. It was found that the density of one (67% lower than control) and three strands (control) had the same effect on the investigated properties. The study provides significant insights regarding how different pollen densities will affect the fruit quality and yield of date palms.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138948823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vineyards, a huge amount of chemical fertilizer was applied to get higher yield. However, the application of farmyard manure (FYM) in vineyards can be the best possible way to enhance the yield and sustain good soil health. FYM application is the most drudgery prone operation in grapes cultivation, mostly done manually. Therefore, an automated solution was developed and assessed for the purpose of dispensing FYM alongside the plant roots on both sides consistently. The FYM applicator consisted of a mixing chamber, a hydraulic motor with a flow control valve, a pair of augurs for dispensing FYM and a conveyor-type side dispensing unit. The FYM applicator is operated with a hydraulic motor. The amount of FYM required can be controlled with the flow control valve as well as with the tractor engine speed. The FYM applicator has a width of 2.3–2.6 m to match the vineyard row spacing of 2.5–3.0 m. Dunnett test indicated that the rate of FYM application significantly (<i>p</i> &lt; 0.05) changes with tractor engine speed, while physical properties vary with the material used for fabrication of the hopper. The equipment can deliver FYM at the rate of 7.8 kg/min from each outlet at 1000 rpm of the tractor engine speed, as per recommended dose. The field capacity and field efficiency of the developed FYM applicator are found to be 0.2 ha/h and 71%, respectively.

In this work, we studied how 'Zorzal,' the most sown cultivar in Chile copes with drought stress and the mechanisms used to deal with it. A greenhouse experiment was performed during the 2019–2020 growing season. Plants were subjected to a severe drought stress suspending irrigation at the pre-flowering stage.

However, seed production was significantly reduced. Our results evidence that ‘Zorzal,’ the most widely cultivated cultivar of common bean in Chile, has good physiological and anatomical treats for plant survivance under drought stress conditions.

In this context, the objective of this study was to identify water-deficit-tolerant plants within the genetic variability of tomatoes and to select drought-tolerant genotypes from the second generation of the first backcross (F₂BC₁). For this, seven wild accessions, three <i>S. lycopersicum</i> var. <i>cerasiforme</i> accessions, and six commercial cultivars were tested.

Three experiments were conducted where the genotypes were subjected to water deficit and physiological and growth parameters. The commercial tomatoes were the most susceptible to water deficit. Among the tested <i>cerasiform</i> varieties, the RVC 66 accession was the least affected by the reduced water supply. The LA 716 accession (<i>S. pennellii</i>) had the highest tolerance to water deficit, followed by ‘LA 1401’ (<i>S. galapagense</i>) and ‘LA 1967’ (<i>S. chilense</i>). The LA 716 accession was the most promising to introgress drought tolerance-related genes in the commercial tomatoes compared to the intraspecific crosses.

The study was conducted in two main maize-producing regions of Eswatini, the Highveld at Mankayane and Middleveld at Luve. Additionally, on-farm trials were established for two cropping seasons to evaluate maize response to three fertiliser regimes: cattle manure only, cattle manure plus inorganic fertiliser, and inorganic fertiliser only and lastly to determine the most economic fertiliser regime.

Biochar-based controlled-release N fertilizers (BCRNFs) are a new concept to address the N loss problem and increase yield. In this research, different BCRNFs were developed by impregnating ammonium sulphate (AS) into biochar (BC) and mixing with bentonite (Be), biosolid (BS), rice starch (RS), and bioasphalt (BA) in a different ratio to formulate three new BCRNFs— S1: 40% AS + 55% BC + 5% RS; S2: 50% AS + 15% BC + 15% BS + 20% RS; and S3: 15% AS + 30% BC + 10% Be + 45% BA. Dry pellets of S1 and S2 were coated with 5 wt% poly-lactic acid solution, while pellets of S3 were not coated. The release pattern of N from the BCRNFs was studied in water. The cumulative release of NH₄⁺–N from S1, S2, and S3 was significantly slower than that from AS. The release time of 80% N from S3 was extended up to 30 h. The greenhouse evaluation of BCRNFs consisted of six treatments: control (no N), non-BC commercial controlled-release fertilizer (CCRF), AS, S1, S2, and S3.
