Wheat and legume species were sown in separate plots and these plants were harvested when wheat reached the dough stage about 180 days after plant emergence. The present study was conducted in a factorial (3 legume species×3 inoculants×5 mixtures) arrangement design. Results showed that effects of legume species on ADF, crude ash, pH, lactic acid bacteria, enterobacteria, yeast and mold, lactic acid, acetic acid, propionic acid, butyric acid and ammonia nitrogen were significant (P < 0.05). Crude protein, silage fermentation features and microbial populations were affected (P<0.05) by inoculants. Effects of mixture ratios on dry matter, chemical compositions, relative feed value, fermentation parameters of silages were significant (P < 0.05). It was determined that ensiling the 50 % wheat with 50% grass pea with the use of inoculant 1188 as an additive could give a good result both in terms of nutritive value and fermentation quality.

In the present study 18 different rice germplasms for their cell membrane injury (CMI), cell membrane stability (CMS), ATPase activity and their relevance to seed germination and seedling growth tolerance index (TI) under abiotic stresses like salinity and low Ψw were investigated. At least 12 germplasms had relatively low membrane injury (< 10%) and consequently high membrane stability (> 90) including TM-1-5, Sadachikon, SR x P 5222, BR 23, Pokkali, Nonabokra, etc. indicating a relationship between stress tolerance and CMS. ATPase activities in some of these rice germplasms were high along with CMS related to stress tolerance. The TI of seed germinations and seedling growth of different germplasms under salinity stress were affected in different degrees and decreased more under high intensities. At 0.l Molal NaCl all germplasms had ≤ 80% TI of seed germination, at 0.2 Molal NaCl only three had ≥ 80% TI and ten had ≥ 50% TI and at 0.3 Molal NaC1, only nine had ~10-32% TI and the rest nine did not germinate. Osmoticum PEG-6000 at -5.5 bar Ψw had limited inhibitory effect on seed germination TI. NaCl as well as PEG-6000 degraded both the root and shoot growth TI of the seedlings. Bangladesh J.

The experiment consisted of nine treatments viz. control, F4, SOF0, SOF1, SOF2, SOF3, SOF4, SSF0 and SSF1. Results revealed that seed soaking with 10 ppm NAA in combination with 75% recommended dose nitrogen (RDN) produced tallest plants and maximum number of tillers, leaves, total dry matter per plant with significant variations in majority of case in both the sowing time. In case of November 15 sown wheat, seed soaking with 10 ppm NAA in combination with 75% RDN treatment resulted maximum number of effective tillers per plant (6.67), longest spike (9.75), highest dry weight of spike (16.54 cm), highest number of grains per plant (198.08) and maximum yield per plant (7.75 g). Maximum yield per plant obtained from this best performed treatment was 24.80 and 19.81% higher over 10 ppm NAA in combination with RDN and RDN treatment alone, respectively. Findings showed that seed soaking treatment was more effective than foliar spray treatment and wheat sown on November 15 produced better stimulation than sown on November 22 in majority of case. Out of nine treatments, seed soaking with 10 ppm NAA in combination with 75% RDN resulted higher growth and maximum yield in BARI Gom-25. Bangladesh J.
