Various pruning intensities viz. control (no pruning), 25% pruning, 50% pruning and 75% pruning were carried out after harvesting of winter crop (in the month of April). Results showed that maximum flower count/shoot (18 number), fruit number/plant (2237), yield/plant (172.6 kg/tree), average fruit weight (102 g) and SSC (8.11%) were found with 25% pruning intensity; whereas, minimum fruit number/plant (720) and yield (70.11 kg/plant) was found in trees treated with 75% pruning intensity. Maximum fruit length (57.49 mm) and fruit width (64.75 mm) was observed in 25% pruned trees. It can be concluded that among various pruning intensities 25% pruning level is best to increase quality and yield guava fruit.","PeriodicalId":14975,"journal":{"name":"Journal of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44919848","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}

The field experiment was conducted in 2019-20 and carried out in alkaline soil (pH 8.2) with low organic matter (0.45%) to grow wheat after rice and treatments were arranged in randomized complete block design. Farmyard manure (FYM 20.5 Mg/ha), rice crop residues application (CRA 100%) and chemical fertilizers (CF) N-P-K 100-80-60 kg/ha, respectively were used under conventional and conservation tillage systems. During this research different growth and yield parameters were noted and evaluated the level of N, P, K and organic matter contents from soil and plant at the harvest. The results indicated that the combined application of FYM and CRA with CF improved the chlorophyll contents (20% in conventional tillage and 39% in conservation tillage) which helped in nutrient translocation (N, P, K) and increased growth, biological and grain yield by improving soil organic carbon (SOC) and organic matter contents in soil. Growth parameter i.e. germination percentage upto 64%, plant height 27% and spike length upto 35% were increased by T7 . The conservation tillage method was the best where we used T7 i.e. CF + 25% FYM + 50% CRA, and CF + 50% FYM + 25% CRA by conserving moisture and built OM (0.90%), soil organic carbon (0.49%) and mineral nutrition in soil as well as in wheat leaves. It is concluded that the integrated use of organic and inorganic resources are helpful for sustainable wheat production by enhancing fertilizer use efficiency (FUE) to improve soil health especially in arid to semi-arid climate conditions in alkaline soil.","PeriodicalId":14975,"journal":{"name":"Journal of Agricultural Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46477658","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}

To enhance nitrogen fixation for higher yield, the effect of bacterial strains on nodulation was evaluated for yield contributing traits of chickpea at Arid Zone Research Institute, Bhakkar, Pakistan during 2019-20. Six Rhizobium inoculations i.e. Providencia vermicola, Enterobacter cloacae, Bacillus mojavensis, Mesorhizobium ciceri-11, Mesorhizobium ciceri-1 and Bacillus subtilis were tested on two chickpea genotypes i.e. Bhakkar-2011 and Thal-2020. A consortium of six bacterial strains was applied at the time of sowing as a seed coating on a sandy soil. Results showed a significant increase in height/plant, nodulation, 100 grain weight, pods/plant and grain yield (kg/ha) due to bacterial inoculation. Nodules/plant were also increased from 44.08 to 76.16. Maximum number of nodules plant-1 were counted as 76.16 with 2.59 g fresh and 0.64 g dry weight per plant in treatment combination viz. Thal-2020 × RP08+RS14+RZ11 thus showing the specific symbiotic relationship among the genotypes and Rhizobium inoculum. In comparison to the control, the PSB, nitrogen-fixing bacteria and rhizobium inoculum results were 52 % increase in pods/ plant. The maximum number of pods/plant (116.00) and100 grain weight (27.73 g) were recorded in V1 × T1 (RP08+RS14+ RZ11). The weight of 100 grains was increased by 40% over the control. T1 had the highest 100 grain weight of 27.73 g, followed by V1 x T3 with a 100 grain weight of 26.22 g.

Thal-2020 had the highest grain yield of 3732 kg/ha, while V2 (Bhakkar-2011) had the lowest at 3516 kg/ha. Inoculation with rhizobium consortium improved grain yield by 30% (2617 to 3732 kg/ha).

Calmodulin is calcium binding protein in plant with multifunction to modulate thermo-stress by calcium based signaling process. Many diverse types of calcium sensors release owing to varying concentration of calcium (stimulus). In plants, CaM (calmodulin) is the most important calcium sensor. Achievements in designing of complete genomes of different crops have prompted to explicate and classify various CaM binding proteins. Genetic studies on CaM revealed that it contains multiple proteins, unique kinases and transcriptional factors which help the plants in adaptation against heat stress conditions. Crop improvement could be only possible by having satisfactory acquaintance on stress tolerance mechanism and a brief knowledge on CaM and its related proteins would be obliging in order to acquire its proper functions in plant growth and developmental pathways under extreme conditons.

The experiment was comprised of seven treatments under Randomized Complete Block Design (RCBD) replicated thrice. The experiment was repeated for consecutive three years to find the effect of microbial inoculants with auxin precursor L-TRP and mean of three years was reported in the manuscript. The microbial inoculants were applied as seed coating. The bacterial inoculation showed promising results as compared to control. However, the consortium of PGPR and P-solubilizer with precursor had the significant effects on cotton yield during all three years of experiment. The consortium increased the yield parameters of cotton i.e., 1810 kg/ha in comparison with un-inoculated control i.e., 1672 kg/ha. Individual applications of PGPR and P-solubilizer also had significant effect on the yield compared to control.

Current study focused on the compound annual growth rates of production, export quantity and value of mostly exported fruits and vegetables. Growth trends of selected commodities were executed by using semitrend growth model. Coefficient of variation technique was used to find out instability of specific commodity for specific country/market. Selected exported vegetables (potato, tomato, onion and garlic) indicated instability results for Sri Lanka, Malaysia, Qatar and Indonesia among given markets and within the given period. Among fruits kinnow export shared 24.96, mango export results showed 22.08 percent share in total fruits export followed by 13.55 percent share of orange and 8.6 percent export share of dates dried in total export from Pakistan. Results observed for instability of exports to countries, minimum value of coefficient of variation (24.34 percent) was recorded for Bahrein market for kinnow export and Bahrein market was stable among given markets. Similarly, mango results showed that export of mango to Germany market was stable among given markets and within the given period. Export of orange to Saudi Arabia market and export of dates to Bangladesh market was stable among given markets within the given period of time.

Consequently, the harvesting of carrot is most laborious and time consuming operation among its all farm operations due to narrow time span for harvesting. hence in order to address the carrot harvesting issue, two row tractor operated carrot harvester cum trimmer was designed and developed by Agriculture Mechanization Research Institute (Research Division), Faisalabad, Pakistan to dig, separate, de-top and collect carrots simultaneously during 2019-20. The main components of harvester were digging unit, lifting unit, soil separation unit, trimming unit, carrot storage bin, leaf slides and hydraulic power transmission system.
