Piezoelectric Properties of Solid Solution Ceramics - A Note
Piezoelectric coupling coefficient for compositions in the quaternary system (BaPb) (NbZr)O3 using Mason’s technique are reported. It is found that the radial coupling coefficient is maximum for compositions at the morphotrophic boundaries in both tetragonal and orthorhombic phases of the system

Optimal Exploitation of Native Arbuscular and Vesicular-Arbuscular Mycorrhizae for Improving the Yield of Banana through IPNM
280-285The R&D banana orchard of the North Maharashtra
University harboured
diversified species of vesicular-arbuscular mycorrhizal (VAM) fungi belonging
to the genera Glomus, Gigaspora, Sclerocystis and Scutellospora. These
fungi infected the roots severely (78.3%) and showed elevated (68.7 g-1
soil) spore density in the mycorrhizosphere of plants for
integrated plant nutrition management (IPNM) system as compared to chemical fertilizers
alone (traditional farming; 49.2% & 39.3 g-1 soil). This resulted
in retardation of the establishment of nematodes in root zone of IPNM treatment
(2.1 g-1 soil) as compared to chemical treatment (5.5 g-1
soil). VAM fungi enabled proper nourishment and protection of crop in IPNM
treatment as compared to traditional way, which was evident from (a) reduced
plant mortality (12%) of planted sword suckers, (b) enhanced greenery (foliar
chlorophyll
778 μg g-1), (c) improved
nutrient uptake on dry weight basis (3.62% N; 0.31 % P; & 6.45% K), (d)
elevated finger number (137.6 per bunch) size (length 21.6 cm & girth 12.4
cm) and weight (130.8 g), and (e) overall vigour and robustness. Hence, exploitation
of V AM through adoption of IPNM system revealed the (i) relatively increased banana
productivity (76.5%,72 tonnes ha-1) and recyclable biowaste (36.6 kg),
(ii) saving of 50% chemical fertilizers,
and (iii) permitted control over soil fertility
in farmer's favour over traditional cultivation practices. These findings related
to native VAM fungi in IPNM, traditional farming and typical soil systems for cultivation
of bananas are discussed in detail
