  A pot experiment was carried out to study the effect of different levels of Zn viz., 0, 5, 10 and 15 kg ha-1 along with a basal dose of NPK (175 kg N, 110 kg P2O5 and 100 kg K2O ha-1) on the Zn content of soil and chemical composition of rice Zn content of soil, leaves, roots, grain and straw of rice increased significantly with an increase in Zn fertilization. Similarly, significant maximum N and K content of rice grain and straw were found where zinc was applied @ 15 kg Zn ha-1. However, a decrease in its P concentration was found with the application of zinc.

  Response of rice variety IRRI-6 to various levels of zinc was studied in a pot culture experiment. Zinc was applied at the rate of 0, 5, 10 and 15 kg ha-1 in the form of ZnSO4 along with a basal dose of 175 kg N, 110 kg P2O5 and 100 kg K2O ha-1. The results showed that all the yield and yield components of rice increased significantly with increasing level of zinc fertilizer. However, significantly maximum plant height, average number of productive tillers per plant, panicles per plant, spikelets per panicle, 1000 paddy weight and grain and straw yield were obtained where Zn was applied at the rate of 10 kg ha-1 which was statistically at par with the treatments receiving Zn at the rate of 15 kg ha-1 except number of spikelets per panicle of rice.

  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.

  An experiment involving 8 x 8 diallel crossing was conducted with rice to investigate the nature of gene action in governing the various traits studied and to explore the combining ability behavior of various genotypes used in the studies. Twelve agro-physiological characters were included in the study in F1 generation. High additive effects were recorded for plant height, panicle length, productive tillers/plant and primary branches/panicle. The non-additive effects were more pronounced for panicle fertility, days to maturity, shoot dry weight, paddy yield; Na, Ca and K contents of the shoot and K/Na ratio of the shoot. Out of the height parental lines/varieties studied Jhona-349 and Bas-385, respectively, proved to be the best general and specific combiners in the experiment under salinized soil conditions.

  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).

  A field experiment was conducted to investigate effect of micronutrients (ZnSO4, MnSO4 and FeSO4) as pre-sowing seed treatment of Peela Raya (Brassica carianata L.). Seed treatments comprised of control (un-soaked), 12 hours soaking of seed in distilled water and in solutions of 0.5 M FeSO4, 0.5 M MnSO4 and 0.5 M ZnSO4. The soaked seed was then dried under the shade for 12 hours before sowing. The results showed that yield parameters such as number of primary branches per plant, plant height at maturity, days to 50% flowering, number of pods per plant, number of seeds per pod were affected to a considerable extent. Seeds treated with ZnSO4 gave the highest values of yield parameters.

  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.

  In a field experiment, comparative effect of three different methods of zinc application was studied, aimed at alleviating Zn deficiency in transplanted flood rice (cv.IRRI.6) grown in alkaline calcareous soil. Three methods were tried i.e. nursery root dipping in 1.0% ZnSO4, 0.20% ZnSO4 solution spray after transplanting and 10 kg Zn ha-1 by field broad cast method. Zinc content of soil before flowering and after harvest was increased significantly for all the methods. The yield and yield parameters increased significantly by the application of Zn by any method. Among the methods the effect of Zn was non-significant on yield components like tillers m-2, spikelets panicle-1, % filled grains, 1000-grain weight and straw yield. However, soil application of Zn @ 10 kg ha-1 was rated superior because it produced significantly higher paddy yield.
