Therefore, a lysimetric study was undertaken to remediate hazardous effects of brackish water on rice-wheat crops through practicable and economical methods in two different textured soils. Treatments were: (A) Types of soils. 1) sandy loam, 2) clay loam, (B) Remedial strategies, 1). canal water, 2) saline-sodic tube well water (continuous), 3) three irrigations of tube well water and two of canal water in a cyclic manner (short cyclic use), 4) tube well water + gypsum @ RSC of water, 5) tube well water+ canal water in 1:1 ratio (conjunctive use). Data showed that the highest biomass and paddy/grain yield were produced by canal water (T1) followed by (T3) where three irrigations of tube well water and two of canal water were used in a short cyclic manner. Whereas, growth and yield of rice and wheat crops were significantly reduced by continuous use of brackish water (T2) and maximum pHs, ECe and SAR were noted in this treatment in both textured soils. Different management practices (use of gypsum and blending) also mitigated the ill effects of saline-sodic water. Therefore, it was concluded that when fresh-water resources are finite and use of saline-sodic water is inevitable, cyclic use of canal and saline-sodic water is a wise and profitable management strategy with marginal effect on crop productivity and proves least detrimental for soil health. Comparison of two different textured soils also revealed that brackish water deteriorated the soil properties of clay loam soil more in comparison to sandy loam soil that highlighted the primary role of soil texture for salinity development and must be recognized while using the brackish water for irrigation purpose.","PeriodicalId":338801,"journal":{"name":"Pakistan Journal of Agricultural Research","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121588350","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 research aimed to determine the yield stability of sixteen advance chickpea strains was carried out at eleven diversified locations across the Punjab province of Pakistan during cropping season 2019-20. GGE biplot and mega environment analysis were employed to identify the most stable and high yielding chickpea advance strains. GGE biplot among PC1 and PC2 illustrated that G-10 (K-15019) was ideal genotype performing best across the environments. Higher yield potential coupled with more yield stability across all test environments was recorded in G-10 (K-15019) followed by G-2 (CH47/12), G-12 (K-15001), G-15(CH66/10) and G-16(CH53/12). Mega environment analysis revealed that E8 (Adaptive Research Farm, Karor) and E2 (Nuclear Institute for Agriculture and Biology, Faisalabad) were most discriminating environments for grain yield and most useful for screening of genotypes. Result for yield stability indicated that G-10 (K-15019), G-2 (CH47/12), G-12 (K-15001), G-15 (CH66/10) and G-16 (CH53/12) were higher yielding and more stable across environments, therefore these genotypes may be utilized in chickpea breeding program for development of widely adapted chickpea cultivars. Moreover, G-10 (K-15019) identified as ideal genotype in terms of stability and yield potential may be released as commercial variety for general cultivation in future.","PeriodicalId":338801,"journal":{"name":"Pakistan Journal of Agricultural Research","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116225234","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}

Moench) is a very important cereal crop for human beings and livestock. It is subjected to many diseases in Pakistan like fungal, bacterial, and viral among which the fungal diseases are the most destructive. Colletotrichum graminicola is the causal organism of red leaf spot of sorghum which causes heavy losses to the sorghum crop cultivated in different areas of Pakistan. It produces black anthracnose spots on all the above ground parts especially leaves. In the present study, four fungicides (Aliette, Cabrio Top, Nativo, and Melody Duo) were evaluated against C. graminicola under in-vitro and in-vivo conditions. The poisoned food technique was used for in vitro trials with three concentrations (150 ppm, 200 ppm, and 250 ppm). The most effective concentration of fungicides from laboratory experiment was used in field conditions against red leaf spot of sorghum. Results showed that Cabrio Top was the most effective fungicide by showing 88% fungal inhibition while Native also exhibited good results by showing 78.1% fungal inhibition. The remaining 2 fungicides Melody Duo and Aliette were least effective by showing 48.2% and 37.5% fungal inhibition, respectively. In vivo experiment from all four fungicides, Cabrio Top and Nativo showed best results by controlling 74.57% and 71.52%, respectively disease over control while Melody Duo and Aliette were least effective by controlling 65.31% and 60.08% disease over control.

Sowing time is an important agronomic consideration which should be optimized to ensure better cotton yield and quality. Therefore, this study was performed to determine the potential of cotton genotypes under varied planting times at cotton research institute, Multan during 2018 and 2019. The experiment was comprised of four cotton genotypes IUB-13, MNH-1016, MNH-1020 and MNH-1026 and eight different sowing times viz 1st March, 16th March, 1st April, 16th April, 1st May, 16th May, 1st June and 16th June. The experiment was performed in RCBD with split plot arrangement and was repeated thrice. Sowing times were placed in main plot and cultivars were placed in sub plots. Results revealed that seed cotton yield and fiber strength was more when cotton was planted early between 1st March to 16th April compared to late planted cotton (1st May to 16th June). Highest seed cotton yield was obtained when cotton was sown on 1st April during first year (3946 kg ha-1) and 16th March during second year (3307 kg ha-1). Minimum seed cotton yield (852, 299 kg ha-1) during both years was obtained when cotton was sown on 16th June. Among cotton genotypes highest seed cotton yield was recorded in MNH-1020 during first year (3021 kg ha-1) and MNH-1016 during second year (2150 kg ha-1). However, minimum seed cotton yield, ginning out turn (38.9, 36.6%) and fiber length (27.6, 26.8 cm) were recorded in IUB-13 during both years. MNH-1020 had highest ginning out turn (41.1, 39.3%), fiber strength (35.88, 40.44 g/tex) and fiber length (28.7, 29.2 cm) during both years. MNH-1020 was also least effected with cotton leaf curl virus when planted on 1st March during first year (25.0%) and 16th march sowing during second year (3.0%). In conclusion, cotton cultivar MNH-1020 can sown from 1st March to 16th April in order to get better cotton yield and quality.","PeriodicalId":338801,"journal":{"name":"Pakistan Journal of Agricultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131095478","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}

Current experiment was performed to discover the comparative consequence of various vase solutions to improve the post-harvest qualities and extend vase life of Rosa hybrida cv. Freedom. The research was performed at the research area of Department of Horticultural Sciences, The Islamia University of Bahawalpur. There were 11 treatments comprising of honey (T1), sugar (T2), salicylic acid (T3), acetic acid (T4), indole acetic acid (IAA) (T5) and combination of all solutions with sugar. These treatments were compared with tap water (T0). There were four plants in each treatment with three replications which were arranged according to completely randomized design (CRD) under room temperature. The results showed that maximum fresh weight (g) was obtained in T4 (acetic acid), flower head diameter (mm) and flower color was ideal under T3 (salicylic acid). Maximum dry weight (g), highest flower freshness on 1st and 3rd day, minimum petal discoloration which leads to productive market acceptability and highest vase life was recorded in T2 (sugar). It is worth to note that lowest market acceptability of flower was observed when sugar is combined with other solution especially IAA. It means sugar reduces its effectiveness when combined with growth regulators. From this experiment, it can be concluded that sugar (T2) provide ideal medium for enhancing the post-harvest attributes of Rosa hybrida cv.
