    Relative significance of soil and nitrogenous fertilizer in nitrogen nutrition and growth of wetland rice (Oryza sativa L.) (1991)

    Notizen: Summary A pot experiment was conducted to compare the yields from five commercially cultivated varieties (Bas-198, Bas-370, Bas-Pak, Bas-385, and IR-6) of rice (Oryza sativa L.) and to establish the relative significance of soil N and fertilizer N (15N-labelled ammonium sulphate) in affecting crop performance. Another aim was to study the interaction of fertilizer N and soil N as influenced by different rice varieties. Among the five varieties tested, Bas-Pak gave the maximum dry matter and N yield. The N-use efficiency (percentage of applied N taken up by the plants) of different varieties ranged between 33.7 and 43.7%, Bas-Pak being the most efficient. Significant losses of fertilizer N occurred from the soil-plant system. The maximum N loss (52.1% of applied N) was observed with IR-6 and the minimum loss (39.2%) with Bas-Pak. A substantial increase in the uptake of soil N following the application of fertilizer and an interaction between the two N sources were observed with all varieties except Bas-385. The interaction was attributed to greater root proliferation following the application of fertilizer. It was concluded that a varietey with greater potential to use soil N is likely to give a better yield and that, of the two N sources, the availability of soil N was more important in determining the yield performance of different varieties of rice.

    Availability of soil and fertilizer nitrogen to wetland rice following wheat straw amendment (1991)

    Notizen: Summary A pot experiment was conducted to study the availability of soil and fertilizer N to wetland rice as influenced by wheat straw amendment (organic amendment) and to establish the relative significance of the two sources in affecting crop yield. Straw was incorporated in soil at 0.1, 0.2, and 0.3% before transplanting rice. Inorganic N as 15N-ammonium sulphate was applied at 30, 60, and 90 μg g-1 soil either alone or together with wheat straw in different combinations. After harvesting the rice, the plant and soil samples were analyzed for total N and 15N. Straw incorporation significantly decreased the dry matter and N yield of rice, the decrease being greater with higher rates of straw. The reduction in crop yield following the straw incorporation was attributed mainly to a decrease in the uptake of soil N rather than fertilizer N. The harmful effects of organic matter amendment were mitigated by higher levels of mineral N addition. The uptake of applied N increased and its losses decreased due to the straw incorporation. Mineral N applied alone or together with organic amendment substantially increased the uptake of unlabelled soil N. The increase was attributed to a real added N interaction.

    Effects of waterlogging on growth and some physiological parameters of four Brassica species (1990)

    Notizen: Abstract Waterlogging tolerance of four Brassica species, Brassica campestris L., B. carinata A. Br., B. juncea (L.) Czern and Coss., and B. napus L. was assessed after 4 weeks growth in greenhouse at two waterlogging treatments, unflooded control soil, and fully waterlogged soil. Shoot fresh and dry biomass, in both mean and relative terms, was highest in B. juncea and lowest in B. napus at waterlogging treatment. B. carinata was as good as B. juncea in mean shoot fresh and dry matter but it had almost same relative shoot fresh matter as that in B. campestris, but was second highest in relative shoot dry weight. Waterlogging treatment caused a marked reduction in chlorophyll content in all four species but the species difference was not evident. However, B. juncea and B. napus had lower relative total chlorophyll than the other species. A marked increase in soluble protein content of B. juncea and a significant increase in total amino acids in B. carinata was observed under waterlogged conditions as compared to the other species. At the waterlogging regime, an increase in iron content in both shoots and roots was observed in all four species. B. juncea accumulated lower amount of iron in both shoots and roots as compared to the other species, whereas B. carinata had also lower iron in the roots. The species did not differ for shoot manganese content but B. carinata had significantly higher manganese in the roots as compared to the other species.

    Salinity effects on five cultivars/lines of pearl millet (Pennisetum americanum [L] leeke) (1987)

    Notizen: Abstract The effects of increased salinity [NaCl + CaCl2] on seedlings of five accessions of pearl millet grown for 2 and 7 weeks, respectively, in salinised solution cultures at EC 0.6, 4, 8, 12, 16, and 20 ds m−1 and sand cultures at EC 0.6 and 20 were assessed. There were no consistent relationships between seedlings characters at two and seven weeks in response to increased salinity, and no single character provided an acceptable means of differentiating cultivar/line response. The line having lower shoot mortality had a high root weight, a shoot:root ratio approaching 1, the greatest shoot water content, and the greatest plant height. No relationship was found between these whole-plant characters which suggest greater salinity tolerance, and the pattern of ion distribution, particularly Na+ and Cl−. Sufficient inter-cultivar/line variation in response to salinity was found to suggest that selection of individuals with increased salinity tolerance is possible within pearl millet.

    Notizen: Abstract The salt tolerance of two cultivars of mung bean (Vigna radiata (L.) Wilczek), AuMg 588 and Mg 6601, was assessed at germination and at the seedling stage. Increasing salt concentration significantly reduced the percentage germination, fresh and dry weights, protein and carbohydrate contents of all plant parts, leaf area, shoot and root lengths, shoot/ root ratio, chlorophylls a, and b, and total chlorophyll in both the cultivars. At high salinities, cv AuMg 588 had greater fresh and dry weights of all plant parts, than cv Mg 6601, but the latter had greater chlorophyll a, and b, and total chlorophyll contents than cv AuMg 588. Cultivars did not differ significantly in other characters measured.Vigna radiata is very sensitive to salt.

    Notizen: Summary Narrow sense heritabilities of tolerance to NaCl were estimated in seven grass species using seedling root length after three weeks growth in solution culture containing NaCl. Heritability estimates were obtained from i) female parent-progeny regression, and from ii) selection response and selection differential (realized heritability). Estimates from parent-progeny regression; and realized heritability respectively for each species were as follows Lolium perence L. 0.44, 0.39; Dactylis glomerata L. 0.32, 0.24; Agrostis stolonifera L. 0.28, 0.27; A. castellana L. 0.26; 0.31; Holcus lanatus L. 0.19, 0.23; Festuca rubra L. 0.44, 0.36; Pucinnellia distans (L.) Parl. 0.72, 0.77. These data suggest that in all species except perhaps H. lanatus, improvement in seedling NaCl tolerance could be obtained through further selection and breeding.
