  Mechanically and manually prepared stock and scion for bench grafting were adopted in four phases for apple propagation i.e., mechanically made stock and manually prepared scion, second phase was vice versa while in third stage both the stock and scion were prepared mechanically. In fourth operation all the grafting process was performed by hand made scion and stock. Maximum sprouting and success percentage of 93.2 and 83.2 respectively was recorded in the mechanically prepared scion and stock. Results proved that this operation was also the most efficient which took 95.4 minutes only to graft hundred plants of apple. In conclusion mechanical technique for bench grafting in apple propagation was recorded as the best and efficient method.

  Field experiment on summer maize was conducted in farmer's field at Mardan. The experimental area was sandy clay loam in texture with variable soil salinity and sodicity level. Maize crop was sown with furrow-bed and basin irrigation method. The regression models for total biomass and grain yield with soil salinity and sodicity gave better R2 values under furrow-bed than basin irrigation method. There was about 24, 45 and 68 % increase in total fresh biomass, dry straw and grain yield under furrow-bed system from that of basin irrigation method, respectively. The water use efficiency of 3.15 and 6.57 kg ha-1 m m-1 was achieved in basin and furrow-bed irrigation, respectively.

  Agricultural production in Pakistan on one hand is constrained by scare water availability, soil salinity/sodicity and waterlogging problems on the other hand irrigation application losses on the field are around 25-40%. To evaluate two planting methods (basin and furrow-bed) studies on the same fields were conducted for three consecutive years (1999-2001) adopting two planting methods (basin and furrow-bed). The results indicated that under furrow-bed on the average, there was 29% less, irrigation depths with 42% greater grain yield compared to basin. The water use efficiency (WUE) was 68% greater with 35% less weed infestation under furrow-bed compared to basin. Generally, for maize greater benefits of raised beds can be achieved on problematic soils especially during seasons with high/concentrated rainfalls.

  It was observed that about 75 percent grid points showed gradual increasing trend in pH with depth. The difference in pH of 0-15 cm and 60-90 cm layers ranged from 0.04 to 1.36 units with an average value of 0.56 units. Soil salinity (EC) depicted mainly mixed trend. It was further observed that 18.3 percent area possesses pH greater than critical level (8.5) in surface layer. Proportions of problematic area increased in sub-surface layers. There was quite variation in yield and yield components. Patchy sodicity problem reduced productivity of the study site by about 15 percent.
