    Impact of drip irrigation on microbial activity in summer mungbean
    (Punjab Agricultural University, Ludhiana, 2016) Harpinder Singh; Siag, Mukesh
    A field experiment was conducted in the summer of 2015 at PAU to determine the impact of drip irrigation on soil microbial activity, nodulation, growth and yield in summer mungbean. A mungbean variety “SML-832” was sown with three drip irrigation treatments of I1:1.0ETc, I2:0.80ETc, I3:0.60ETc and one controlled flood irrigation treatment. There was significant difference between treatments for growth parameters of plant height, leaf area index, root weight and chlorophyll content. Similarly, for symbiotic traits of nodule count, nodule dry weight and leghemoglobin content in nodules at flowering stage and yield parameters of grain yield, number of pods and grains per plant, significant difference existed between irrigation treatments. However for all growth, symbiotic traits and yield parameters there was non-significant difference between I1 and I2 treatments. The maximum number of nodules per plant (34.53), nodule dry weight (76.66 mg) and grain yield (1107 kg/ha) was in I2 while the minimum number of nodules (14.93), dry weight of nodules (44.46 mg) and grain yield (778 kg/ha) was in flood irrigation treatment. In case of soil quality parameters the viable count of soil microbes increased from sowing to flowering stage but decreased at maturity of crop. During flowering stage, the maximum viable count of soil bacteria (6.57 log Cfu/g), actinomycetes (5.52 log Cfu/g) and fungi (4.87 log Cfu/g) was found under I2 irrigation treatment while minimum under flood irrigation. Nodule count per plant and microbial activity in soil has positive linear correlation with crop yield. From the study it was concluded that drip irrigation in mungbean results in higher microbial activity in soil, increase in nodulation and better crop yield.

    Development of web enabled water resource information system for SAS Nagar and Patiala district
    (Punjab Agricultural University, Ludhiana, 2016) Banjeet Singh; Samanpreet Kaur
    India is the largest groundwater user in the world, with an estimated usage of around 230 cubic kilometers per year, more than a quarter of the global total. With more than 60 per cent of irrigated agriculture and 85 per cent of drinking water supplies dependent on it, groundwater is a vital resource for rural areas in India. Thus it is of great importance to compile up to date information about the water requirement for the irrigation & drinking purpose for all the districts in Punjab. Remote sensing and Geographic Information system (GIS) are the technologies that can provide efficient & effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web enabled water resource information system has been developed in GIS environment for the SAS Nagar and Patiala district, Punjab by using the open source software - MS4W and pmapper. This system provides digital information of natural i.e. drainage & man made features like roads, canals, tube well with its location etc for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for the planners and policy makers so that the areas where the problem related to water quality can be indentified and focused upon. The system can provide an effective and meaningful direction for the planning and development of both districts.
