...lls to 12.75 t ha-1 with full irrigation in favorable environments. Benefit-cost analysis shows that break-even point can be achieved in fourth year of plantation of Jatropha. The projected consumption in Pakistan for petro-fuel for 2025 is 35.1 mt, which is almost double of the current consumption. Thus, the target projections for replacement of petro-fuel with bio-diesel will be 3.51 mt for which 3.5 mha of land is required, as Jatropha has to be grown in ma...

EFFECT OF DEFICIT IRRIGATION, SOWING METHODS AND MULCHING ON WHEAT YIELD AND NITROGEN UPTAKE
...on with four levels viz: full irrigation (DI ), 20% deficit irrigation (DI ), 40% deficit irrigation (DI ) and 60% deficit irrigation (DI ). Soil moisture was continuously monitored and full irrigation was determined on the basis of 50% Management Allowed Deficit (MAD). Results indicated that sowing methods, mulching and various levels of deficit irrigation significantly (P<0.05) affected wheat yield and nitrogen uptake. ...

...r irrigation levels i.e. full irrigation (I0), 15% deficit (I15), 30% deficit (I30) and 45% deficit (I45) along with four Nitrogen doses i.e. 100% of recommended dose (120kg) (N100), 85% of recommended dose (N85), 70% of recommended dose (N70) and 55% of recommended dose (N55). Frequency Domain Reflectometry (FDR) was used for soil moisture monitoring. Full irrigation was determined on the basis of MAD 30%. Simulation of nit...

...on ridge method and give full irrigations produced higher plant height (192 cm), ridge and one irrigation missing at six leaves stages had more Harvest index (35.06%)) and high Shelling percentage (49.27) was obtained on broadcast planting with full irrigation. On the basis of the above results it is recommended that in water scare area grow maize on ridge planting method and give deficit irrigation at vegetative stage (one ...

... four irrigation levels; full irrigation (I0), 15% deficit (I15), 30% deficit (I30) and 45% deficit (I45); and four nitrogen doses;100% of recommended dose (120 kg ha-1) (N100), 85% of recommended dose (N85), 70% of recommended dose (N70) and 55% of recommended dose (N55). Io was based on 30% of management allowed deficit. Effect of Nitrogen doses on Nitrogen use efficiency (NUE) was found to be highly significant and showed an increasing trend of 7, 25 and 68...

YIELD RESPONSE AND WATER USE EFFICIENCY OF SUGAR BEET IN SEMI-ARID ENVIRONMENT UNDER DIFFERENT DEFICIT IRRIGATION REGIMES
...rigations, designated as full irrigation, 20% deficit irrigation, 40% deficit irrigation and 60% deficit irrigation were tested. Results showed that for all deficit irrigation treatments the root yield was low but the sugar content and water use efficiency were improved. Average root yield for full irrigation was found as 59.75 tonnes ha-J where for 60 % deficit irrigation root yield was 32.02 tonees OO-J• Average sugar...
