  Effect of various weedicides with different doses was studied for chemical weed control and yield of lentil crop. Stomp 330 EC (Pendimothalim) pre-emergence @ 1.00, 1.25 and 1.50 kg ai ha-1, Treflan-R 48 EC (Trifluralin), pre-emergence incorporated @ 0.25, 0.50 and 0.75 kg ai ha-1 and Fusillade 25 EC (Flauzifop butyl) post-emergence @ 0.125, 0.250 and 0.500 kg ai ha-1 were compared with hand weeding on sandy loam saline-sodic soil. The soil having ECe 4.9 dS m-1, pHs 8.70 and SAR 18.10 (m mol l-1) ½ was selected. The test variety was masoor-85. All the weedicides at different doses significantly controlled the weeds but stomp @ 1.50 kg ai ha-1 pre-emergence application produced higher grain yield (1465.00 kg ha-1) among all other treatments which was followed by stomp @ 1.25 kg ai ha-1 (1405.90 kg ha-1) and hand weeding (1405.42 kg ha-1).

  To investigate a suitable and more tolerant brassica variety/line for salt affected soil, a field experiment was conducted for three consecutive years (1997-1999) at soil salinity research institute, Pindi Bhattian. Performance of seven brassica varieties/lines i.e., peela raya, SPS-23-1, SPS-23-2, ORI-56-6, P-8-2, RL-18 and brown raya were studied in ameliorated and non-ameliorated soils. A field having ECe 13.43 d sm-1, pH 9.69 and SAR 65.97 (m mol l-1) ½ was selected, half of which was ameliorated by applying gypsum @ 100 % G.R. and brassica varieties/lines were sown. All cultural practices were applied to the crop. The results showed that germination percentage, plant height, 1000 grain weight and grain yield were maximum in ameliorated than non-ameliorated soil during all the three years. Among varieties/lines, grain yield was in order of P-8-2, OR1-50-6. It is clear from the results that P-8-2 variety gave the highest grain yield (511.68 kg ha-1) among all other varieties/lines in ameliorated/non-ameliorated soils.

  A field experiment was conducted to determine the effect of different tillage implements and rice stubbles as residue on the yield of wheat in saline-sodic soil. Rotavator proved the best among all the tillage implements producing maximum germination counts (35.5 m-2). no. of tillers (289.49 m-2); 1000 grains wt. (45.52 g), grain yield (3.409 t ha-1) and straw yield (3.42 t ha-1). Rice stubbles had better residual effect giving significantly higher values of these parameters than the rice stubbles removed from field before sowing the wheat crop. Incorporation of rice stubbles into soil proved also beneficial in improving health of saline-sodic soil.

  Amelioration of saline-sodic soil [EC=2.8 to 26.5 dSM-1, pH=9.10 to 9.73 and SAR=34.68 to 102.50 (m mol l-1)½] through land preparation methods (Cultivator, Rotavator and Disc plough) and subsequent application of Sulphuric acid (@ 20% of gypsum requirement) during crop growth was evaluated in a field study for two years at Jhottianwala site, Tehsil Pindi Bhattian, District, Hafizabad. It was observed that Disc plough was the most efficient field implement which not only ensured good yields but also enhanced soil improvement. Application of sulphuric acid also proved clearly useful by producing higher yields and promoting rapid soil improvement. The gradual enhancement of rice and wheat yields (grain and straw) and significant decrease in salinity parameters were recorded in this strategy within two years.

  Shoot samples at preflowering stage and grains at maturity from four replicated field trials on advanced germplasm of chickpea along with some of the commercial varieties were collected. Three trials consisted of Desi germplasm with, 12, 12, and 8 entries while the fourth one had 11 entries of Kabuli material. The advanced lines appeared to be highly promising as they gave maximum increase over the old check varieties in grain yield upto 60 percent in first trial followed by 58 percent in second, 53 percent in third and 43 percent in the 4th one. On the overall basis, the whole germplasm under study contained sufficient B and Cu, while Zn and P (in grain) were marginal if not deficient. Almost all the material had relatively higher B in the grain than that of cereals like wheat. After field survey, a followup soil pot culture study was conducted employing 5 varieties and 2 lines on a soil with marginal Zn and B. Variety 6153 responded to 5 mg kg–1 Zn application by 39, CM 72 by 26, NIFA 95 by 17 and mutant CM 1571-1-A by 11 percent, while remaining responded negligibly. Mutant CM 31-1 responded to 1 mg kg–1 B application by 30, CM 1571-1-A, C 44 and 6153 shared the response by 27 percent. Remaining three did not respond or responded negatively. All the entries in the four trials contained marginal Zn i.e., <20 mg kg–1 and sufficient B i.e.,>30 mg kg–1, yet some of them responded to the applications markedly indicating their high B and Zn requirement than reported in the literature.

  Two herbicides namely Logran and Tolkan were evaluated at three different rates i.e., low, medium and high on Inqulab and Pasban varieties of wheat (Triticum aestivum L.). The results showed that herbicide activity index value was maximum with high rates and minimum with low rates of herbicides. Significant improvement was recorded in various morphological and yield components of wheat by low and medium rates while high rates caused detrimental effect. Recommended rates of both Logran and Tolkan produced about 37% greater grain yield than weedy check which was almost equal to hand weeding. Two varieties exhibited non-significant difference for various parameters.

  Two chickpea varieties viz., 90122 and 93081 were subjected to Rhizobium inoculation with BioPower under water stress conditions, imposed by withholding water. Stress reduced all the parameters including yield components and this effect was more pronounced by stress at reproductive stage as compared with vegetative stage. Rhizobium inoculation enhanced yield under both normal and stressed conditions, but its performance was better under normal than under stress. Rhizobium inoculation proved ineffective to recover loss caused by water stress. The two varieties exhibited statistically non-significant differences.

  The performance of six sunflower hybrids i.e 6435, 6470, 6451, SF-177, SF-187 and Hysun-33 was observed during the autumn season 1997. The results revealed that Hysun-33 gave maximum plant height (131.1 cm) and number of leaves per plant (31.23). The maximum number of rows per head (60.62) were recorded in SF-177 while significantly more number of seeds per row (24.54), 1000-seeds weight (53.53) and grain yield (4403 kg ha–1) was observed in SF-187. Hence SF-187 proved to be the best suited cultivar among all the cultivars included in this trial.
