In a 2-year experiment 120, 34.4 and 49.8 kg N, P and K/ha increased the grain yield of 'DR 92' rice (Oryza sativa Linn.) by 46% and of 'Sonalika' bread-wheat (Triticum aestivum Linn. emend. Fiori ...and Paol.) by 85% over the control in rice-wheat cropping sequence, and of 'NLD White' maize (Zea mays Linn.) by 202% and of 'Sonalika' bread-cropping by 176% in maize-wheat cropping system. Rice-wheat cropping gave a net profit of Rs 3,593 from rice and Rs 3,154 from wheat, and maize-wheat cropping of Rs 10,029 from maize and of 7,402 from wheat. Tillers/hill in rice and plant height and grains/ear in wheat in rice-wheat cropping increased significantly due to fertilizer application. The increase in length of ear was not significant.
Simple methods for spore production of Botrytis fabae Sardina were investigated by comparing two media containing Chrysanthemum (Chrysanthemum sinense Sabine) flowers (CHSF) or marigold (Tagetes ...signata) flowers (MGF) supplemented with 3% dextrose (w/w) with the commonly used faba bean dextrose agar (FDA) medium. The UV light irradiation was a prerequisite for mass sporulation of B. fabae on MGF and FDA media while on the CHSF medium a high level of sporulation occurred even under the normal laboratory conditions (18-25 deg C) without UV irradiation. The use of the CHSF medium for mass spore production of B. fabae is, therefore, simple and efficient, and is recommended for use elsewhere especially in the developing world
