Calocybe Indica

General practice in Bangladesh is, after harvest producers leave the non-effective fruiting body of milky white mushroom in the spawn packet as it is. But every fruiting body primordia take some nutrient from the substrate, and the dried & rotten primordia may encourage other competitive fungi or harmful microorganism to grow on the upper surface of the substrate which may affect the fruiting body formation and yield in the subsequent flushes. Therefore, the present study was under taken to know the effect of casing material management technique on yield and yield attributes of milky white mushroom. Five different casing material management technique were practiced in this experiment, such as T1= removal of dried non effective fruiting bodies after each harvest; T2= removal of dried non effective fruiting bodies and filling the casing hole with fresh casing material after each harvest; T3= scraping the upper surface of the substrate after each harvest; T4= scraping the upper surface of the substrate and adding 10% fresh casing material after each harvest; and T5= no disturbance of the casing material (control). Number of effective fruiting body (NEFB), number of flushes, days to total harvest and size of fruiting body were significantly affected by casing material management technique but economic yield and biological efficiency among the treatments were insignificant. Considering all the parameters removal of dried non effective fruiting bodies and filling the casing hole with fresh casing material after each harvest (T2) was the best technique for casing material management.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

Calocybe Indica

The Milky mushroom, Calocybe Indica was cultivated on different agricultural substrate, paddy straw, wheat straw, sugarcane trace and mango dry leaves. The spawning was done by sterilization of all the four substrate. The bags were kept in mushroom growing room with the maintenance of temperature and humidity 30̊ c-35̊ c and 70-80 % respectively. The minimum days requires for completion of spawn run (18.4 days), primordial formation (25.2 days) and days for first harvest (32.4 days) was first observed on cultivation with Paddy straw.  The maximum yield on fresh weight basis and biological efficiency (134.86 %) was also found to be as the same treatment with the Paddy straw as a substrate. The biological efficiency of wheat straw was at par with Sugarcane trace as substrate which was 85.07 % and 85.02 % respectively.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.
