L-846 at research farm of Punjab Agricultural University, Ludhiana. There were two levels of irrigation (i.e., low and high having IW/CPE ratio as 0.75 and 1.00); and two methods of fertilizer application in drip (i.e., manual application and fertigation). The result shows that the plant height was found maximum in sprinkler system (159.10 cm) as compared with drip system (158.90 cm) having treatment of low level of irrigation using Isrtigation. Number of boils per plant was found maximum In drip system (22.96) with low level of irrigation and in sprinkler system (22.20) having treatment of fertigation, respectively. There was no significant difference between all treatments in quality traits (i.e., fibre length, micronaire, fibre maturity coefficient, fibre bundle strength and oil content). Maximum yield (31.10 q/ha) was found in drip system with low level of irrigation followed by spinkler system (28.60 q/ha) with high level of irrigation. Water Use Efficiency (0.47 q/ha-cm) and Nitrogen Use Efficiency (41.47 q/ha-kg) was found more in drip system as compared to sprinkler system.Not Availabl

Application of artificial intelligence and statistical recurrent models in predicting rainfall: A case study of Ludhiana, Punjab
No full textImpact of Rooftop Rainwater Harvesting for Groundwater Recharge
No full textA rooftop rainwater harvesting structure was constructed and the design of filtration unit for ground water recharge evaluated for four years. The other structure constructed at the university library recorded an average of 0.3 million litres groundwater recharge. The success led to construction of six more structures at different places, and currently 20 structures have been established at different places in Punjab under the technical guidance of the university. In the year 2007, eleven structures were evaluated and found that they contributed about 2.01 million litres of rainwater as groundwater recharge. The study revealed that there was a need to adopt this technique at mass level to get significant results. This would be possible only with the help of people, participation. The possibilities to motivate the people for adoption of the technique at mass level have been reviewed
Energy Input-Output Analyses of Major Field Vegetable Crops Production in Punjab
No full textThe energy consumption pattern in Indian agriculture has changed with a marked shift from human and animal power to electrical and mechanical sources of energy (tractors, diesel engines, self-propelled machines). The rising cost of production and depleting energy sources are paramount concerns for the maximization of productivity with minimum input of energy and cost. A study was performed for determining the energy productivity of five major vegetable crops (potato, tomato, muskmelon, garden pea, cauliflower) production systems. Significantly higher (p<0.05) energy consumption was observed for potato cultivation (53,412 ± 2,388 MJ.ha-1), followed by tomato (47,489 ± 1,183 MJ.ha-1), cauliflower (39,367 ± 1,127 MJ.ha-1), muskmelon (37,827 ± 856 MJ.ha-1), and garden pea (24,625 ± 497 MJ.ha-1). Irrigation was observed to be the major energy-consuming farm operation, followed by transportation of farmyard manure (FYM)/fertilisers and produce. Based on the significant contribution of non-renewable and commercial energy in the production of major vegetable crops, the agricultural system was observed to be vulnerable to increase in energy prices through petroleum as well as fertiliser prices. There is a need to include more energy- and cost-effective farm mechanisation and irrigation systems
