Present study entitled was carried out in field irrigation lab, Department of Agricultural Engineering, Aditya Engineering College, Surampalem. In the present experiment locally available agricultural substrate paddy straw, sugarcane bagasse and cocopeat were tested with black soil and farm yard manner as casing materials. For parameters such as days required for spawn run, pinhead formation, harvest days, total yield and biological efficiency were determined. Significant results were obtained for all the experimental parameters and also for the stem length and cap diameter. Best substrate found was the paddy straw in the recent experiment with days required for spawn run (14 days), pin head formation (11.2 days), days for first harvest(50 days), stem length (8.07 cm), capdiameter (8.67 cm), first harvest (489.45 gm), second harvest (453.68 gm), total yield (925.24 gm), biological efficiency (94.31%). The next best in the order was coco peat followed by sugarcane bagasse. Hence this study confirms the suitability of paddy straw for cultivation to mushroom growers and farmyard manure with 15 cm casing thickness as substrate for its cultivation for achieving higher yield. The benefit cost ratio was estimated as 1.57.

Punjab has emerged as an important rice-producing state in the country. The state with 1.53 percent of the geographical area of the country produces more than 11 percent of total rice production in the country. The production of rice in Punjab increased more than 10 times due to an increase in area and yield. The growth of a rice crop at such a high rate over 20 years in Punjab is indeed a rare phenomenon in the history of agricultural development in the world. Due to extensive cultivation of rice in Punjab, the state has been over-exploiting the groundwater, more than its recharge. Most of the tube-well dominated districts of the state, witnessed the fall in water table more than 20 to 30 cm per year. To dispose of the paddy straw, the farmers of Punjab generally opt for burning it. This practice of burning of paddy straw besides nutrient loss is posing a serious problem for the public health and transportation system. Rice has now become a problematic crop for Punjab state due to its ill effects on its natural resources, that is, the water and soil environmental degradation. The Punjab Agricultural University experts and other committees estimated that the total groundwater recharge from all sources can sustain/support only 16-17 lakh ha of paddy in Punjab. The area under the crop increased to 29 lakh ha which was unsustainable in the long run. The area under rice in Punjab should be stabilized at 16-17 lakh ha and the remaining paddy area should be shifted to other crops like pulses, oilseeds, maize, fruits, and vegetables, etc. requiringless water, to achieve proper water balance. Thus diversification of some area from paddy is in the interest of Punjab farmers, State government and the Central government for long term food security on a sustainable basis.

In this paper we provide new data about the soil enzyme activity as a biological process, which is an indicator for impacts of factorial combinations of lime and fertilizers applications. Five plots divided into fifteen subplots were sampled for determination of the enzymatic indicators of soil quality, based on the actual and potential dehydrogenase and catalase activities. The research revealed that limed soil samples, in comparison with unlimed ones, resulted in significantly higher soil enzymatic activities (p[0.05) in the upper (0-20 cm), while in the deeper (20-40 cm) layer, only catalase activity was significantly higher (at least at p[0.02). Mineral fertilization, in comparison with its farmyard manuring, led to an insignificant increase in each of the three enzymatic activities determined, excepting catalase activity which was significantly higher (0.05]p]0.02) in the 0-20 cm layer. Based on the absolute values of the enzymatic activities, the enzymatic indicators of soil quality (EISQ) were calculated. The mineral NPK-fertilization and low dose of lime in the 0-20 cm layer, and mineral NP-fertilization and low dose of lime in the 20-40 cm layer proved to be the best variants of fertilization. The enzymatic indicators of soil quality in these variants reached the highest values: EISQ=0.821 and EISQ=0.889, respectively, indicating the presence of high enzymatic activities. It should be emphasized that a balanced application of lime, mineral fertilizers and farmyard manure leads to the formation of favorable conditions for the development of microorganisms, growth of plants and for an intense and lasting enzymatic activity.
