  Limited supply of canal water forces for seeking alternative sources for the supplementation. For this purpose, the quality of Marh-Chiniot (M-C) drain water was tested in different seasons from irrigation/ reclamation point of view. Results indicated that EC of the waters varied in sampling seasons at different sampling points. In general, EC values ranged between 0.25 and 2.69 dSm-1. Its mean values were calculated as 1.08, 1.06, 1.83 and 1.85 dSm-1 during August 1997, December 1997, June 1998 and February 1999 respectively. The mean SAR of these waters was found below the safe limit of 10 (m.mol L-1) ½ with only one exception for June 1998 when it was having this parameter in marginal range. Respective mean values of SAR for the above months were 8.26, 5.42, 11.79 and 9.5 (m.mol L-1) ½. Values of RSC were found generally high with its computed means of 4.71, 4.13, 7.98 and 6.31 me. L-1 for August, December 1997, June 1998 and February 1999 respectively. The quality of waters varied from upstream to downstream, without a definite trend. The seasonal effect was very much pronounced depending upon the flow of water. It may be concluded that this water can be used for crop production and reclamation purposes with some suitable management practices. However, frequent quality assessment will be needed especially, in different seasons.

  Agromelioration is the approach for reclamation of salt-affected soils in which minimum possible quantity of chemical amendments is applied coupled with organic material/agronomic practices. A field study was conducted to reclaim saline sodic soil through the application of gypsum @ 25 % G.R. alone and in combination with FYM, rice straw, sesbania @ 10 t ha G 1 and crust scraping. A standard treatment of 100 % G.R. was also included. Rice and wheat crops were grown in rotation for two years. Crops were harvested at maturity and soil status was monitored after the harvest of each crop. The rice straw and sesbania coupled with 25 % of G.R. were found to be superior to other treatments but were comparable with 100 % G.R. as far paddy yield of first rice crop was concerned. But in the subsequent wheat, the treatment of 100 % G.R. became inferior. However, the effect of FYM improved. The other treatments where organic matter (rice straw, FYM and sesbania) was applied along with 25 % G.R. became similar with 100 % G.R. at the end of 4th crop in terms of yields. The crust scrapping and gypsum @ 25 % G.R. alone were assessed as inferior techniques. Soil analysis also followed the same trends. The EC of the soil rapidly decreased due to light textured soil but the reduction in soil pH and SAR was gradual.

  Concerted breeding efforts on mungbean improvement at NIAB Faisalabad, Pakistan has resulted in the development of a diverse, high yielding, and disease resistant elite line; NM 89, derived from hybridization between a small seeded variety; NM 20-21 and an exotic large seeded AVRDC accession VC 1482E, after vigorous sifting in different segregating generations. True breeding plant progenies were bulked and were evaluated for yield potential in various yield trials laidout at NIAB, Faisalabad from 1990-95. NM 89 produced seed yield of 1971 kg ha -1 on an overall basis which was 42.77 and 21.77 per cent higher as compared to check varieties NM 20-21 and NM 51 respectively. Based on 1996 and 1997 mean yield performance in adaptation yield trials, NM 89 produced seed yield of 1213 kg ha -1 which was 17 per cent higher as compared to standard check NM 51. Among yield components, NM 89 had the highest number of pods per plant. It had shown resistance against Cercospora leaf spot (CLS) and mungbean yellow mosaic virus (MYMV). Based on desirable morphological characteristics and superb seed yield criteria, NM 89 was approved as NIAB MUNG 98 in November, 1998 by the Punjab Seed Council for general cultivation in the Province.

  Field experiments were conducted during 1999-2000 and 2000-2001 to assess the effect of improved Vs traditional practices on the seed yield of improved chickpea cvs NIFA-88 and local.(Desi). Yield components i.e pods per plant, 1000 seed weight and seed yield obtained with improved cv. NIFA-88 and practices was significantly higher than local variety with traditional practices booth the years respectively. Although plant height and branches per plant did not differ significantly but generally increased occurred with improved practices. The yield increase over traditional practices appeared 7 to 27% both the years which may have been results of the joint impact of the improved practices thus, the use of improved chickpea cv. "NIFA-88" with proper managed practices i.e one deep-plough before moon soon rain and then disc harrowing after rain before sowing of crop, using a fertilizer @ (20-50 NP kg ha-1) broadcast and incorporated with rotavator and seed rate of 75 kg ha-1 treated with vitavax-200 @ 2 gm kg-1 proved to be the recommended technology for obtaining maximum seed yield under the Rodh-kohi condition.
