  The experiment was conducted to investigate the yield and nutrient losses and economic return at various stages of harvest in potato crop. Plant height and plant spread increased from 31.8 and 41.58 at HD60 to 40.3 and 50.58 cm at HD90. The number of stems per plant also increased from 3.55 at HD60 to 6.45 when the crop was harvested at HD90. Specific gravity and dry matter content also increased when harvesting was delayed to the optimum time. Specific gravity and dry matter contents increased from 1.075 and 19.60% at HD60 to 1.083 and 21.31% at HD90, respectively. The starch content increased gradually from 14.79% at HD60 to 15.65% at HD90 while total sugars decreased with an increase in developmental stage. It decreased from 707.75 mg/100g at HD60 to 549.50 mg/100g at HD90. Early harvested crop resulted in smaller tuber size (39.20 mm) and low yield (7.79 t ha-1) at HD60 which increased to a tuber size of 64.1 mm, yielding 11.45 t ha-1 at HD90. The highest gross benefit (Rs. 60,810 ha-1) was obtained at HD60 (Rs. 60810), which decreased to Rs. 53,940 ha-1 at HD90. These results suggested that although early harvest gave poor quality tubers and low yield but the market demand at this stage is high and the growers get higher return from early harvesting.

  To determine association between any two of the three traits of cold tolerance, growth habit and anthocyanin pigment in lentil (Lens culinaris Medikus), F2 populations were studied for two years (1991/92 and 1992/93) at Quetta and F3 for one year (1992/93) at two different field sites, Quetta and Kalat, Balochistan, Pakistan. Highly significant (p<0.001) association between any two of the three traits in all possible combinations was found which indicates that indirect selection for winter hardiness, using prostrate growth habit and anthocyanin pigment, is possible.

  The results showed that all cultivars (Ford, Ertou No.2, FS-85, Hong Kong and Williams) varied significantly in yield components. The cultivar FS-85 gave significantly higher seed yield (1851.65 kg ha –1) than other cultivars due to higher number of pods plant–1, number of seeds pod–1 and seed weight and appeared to be the best under Faisalabad conditions.

  The objective of this study was to develop a dual-season high yielding, bold-seeded lentil variety with cold, drought and disease resistance to replace the local ultra small-seeded variety in the arid highlands (≥1000m altitude) of Balochistan which are equal to 25 per cent of the total land area of Pakistan. SHIRAZ-96 significantly (P<0.05) out-yielded the check (Balochistan Local) in 20 and remained non-significant (P>0.05) in seed yield at 7 sites. The seed increase of SHIRAZ-96 over local lentil ranged from 10-81 per cent. The maximum average yield of 1637 kg ha -1 (33 per cent > local) was obtained under irrigated conditions and 410 kg ha -1 (47 per cent > local) in rainfed environments. SHIRAZ-96 provided at least the seed back in the most dry (≤100mm precipitation) conditions when the local lentil could not produce any seed at all in those environments. SHIRAZ-96 survived -18 °C which is little less cold tolerant than the local which survived -19 °C under controlled freezing tests. These findings were analogous to the results obtained under natural environments in upland Balochistan. SHIRAZ-96 is Fusarium wilt resistant and tolerant to Ascochyta blight. It is almost same in cooking time, taste preference and protein contents but more than double in seed size as compared to the check, Balochistan local.

  The comparative yield potential of seven mungbean genotypes namely; NM-92, NM-89, NM-15-11, NM-49-7, NM-22-5-1, 6153 B-20 and 6173 B-10 was studied under field conditions. The yield components like number of pod bearing branches plant–1, number of pods plant–1, number of seeds pod–1 and 100-grain weight differed significantly among all the genotypes. Genotype NM-89 produced maximum grain yield which was, however, statistically similar to those of NM-15-11, NM-22-5-1 and NM-92. Protein contents in grains did not differ significantly among the genotypes.

  Seasonal change in cold hardiness has frequently been associated with metabolic induction of osmolytes that may play a role in acclimation to low temperatures in cool season crop plants. The present research was aimed to examine the association of common endogenous sugars with cold hardiness in acclimated and non-acclimated plants of winter-hardy and non-hardy lentil (Lens culinaris Medik.) genotypes under controlled conditions. The genotypes were highly significantly (p<0.01) different for cold tolerance at -5°C and the winter hardy genotypes had no foliar damage but 75% injury was observed in the non-hardy genotypes when freeze tested after complete acclimation under controlled conditions. Comparatively, sorbitol concentrations in the tips and basal leaves of young and old shoots of acclimated plants were consistently and highly significantly (p<0.01) higher in the non-hardy cultivars than in the winter-hardy lines. A highly significant (p<0.001) positive correlation (0.74 ± 0.09) was found between cold injury and sorbitol concentration in these tissues. Except for the presence of comparatively high sorbitol in non-hardy genotypes, there was no significant association of other endogenous sugars nor with total soluble sugars and cold hardiness in lentil.

  The treatments tested were two sowing dates (Mid November and end November) and six competition durations (No competition, competition for 4,6,8,10 weeks and full season competition). The experiment was laid out in a split plot arrangement with three replications placing the sowing dates and competition durations in the main and sub plots, respectively. Common weeds of wheat were allowed to compete with crop for different prescribed competition durations. The results revealed that various growth and yield components were significantly influenced by sowing dates and weed competition. Significantly maximum grain yield of 6122.21 kg ha–1 was obtained in no weed competition treatment followed by competition upto 4 to 6 weeks which were statistically at par with each other. However, the sowing dates had no significant effect on final grain yield.

  The results revealed that maximum grain yield (5.56 t ha–1) was obtained with the application of standard recommended dose of chemical fertilizer. However, it was followed by the treatment where 1000 kg ha –1 of EM-Biokasht was applied at sowing. It can thus be concluded that although use of EM-Biokasht did not produce comparable results with that of NPK application, but keeping in view the high cost of NPK fertilization, the use of EM-Biokasht at the rate of 1000 kg ha–1 can be recommended for obtaining a reasonable wheat yield with the addative benefit of producing priced wheat under natural farming system.

  Response of two wheat cultivars namely Inqalab-91 and Punjab-96 to nitrogen levels of 0, 50, 100 and 150 kg ha–1 was studied under field conditions. The cultivar Inqalab-91 gave significantly higher grain yield than cultivar Punjab-96 due to more spike length, number of grains spike–1 and 1000-grain weight. Yield and yield components were also influenced significantly by nitrogen levels. The application of 150 kg N ha–1 produced maximum grain yield of 5.44 t ha–1 which was, however, statistically similar to that of 100 kg N ha–1. The increase in grain yield with nitrogen application was related to higher number of tillers m–2, spike length, number of grains spike–1 and 1000-grain weight.

  Four genotypes of Gossypium hirsutum L; two drought tolerant (NIAB-78, CIM-482) and two susceptible (CIM-446 and FH-1000) were selected to make cross combinations. The parents, F1, F2 and backcross generations of two crosses were studied under drought and normal conditions in the field to find gene action involved in the inheritance of the traits; number of bolls per plant, boll weight, seed cotton yield and ginning out turn. There were significant differences among six generations (P1, P2, F1, F2, BC1 and BC2) of two crosses for all the plant traits both under normal and drought conditions. Generation means analysis revealed additive, dominance and epistatic genetic effects operating in the phenotypic manifestation of the plant characters under both the conditions.

  Group A (control) chicks were placed on commercial feed, group B, C and D were offered feed supplemented with garlic, kalongi and turmeric @0.5 g/ Kg of feed, respectively. Overall weight gain during six weeks was highest (1476.60 g) in chicks of group C followed by those of group D (1340 g), B (1338.97 g) and A (1333.60 g), respectively. Overall feed consumption was apparently highest in chicks of group B (3110 g) followed by group C (3065 g), D (3053 g) and A (2708.33 g), respectively. Overall FCR during six weeks period was apparently best in group C (2.0) followed by group A (2.0), D (2.2) and B (2.3), respectively. Maximum value for antibody titer against ND was recorded in group C (1032), followed by group B (873.33), D (783.33) and group A (558.33), respectively. The maximum antibody titer against IBD was recorded in group C which was 1030 followed by group B (873.33), D (770) and group A (470), respectively. ANOVA on data of both diseases showed significant differences between groups with respect to antibody titre at 6 weeks. Maximum value for serum cholesterol was recorded in group A (134 mg/dL). Followed by group D (115.70 mg/dL), C (105 mg/dL) and group B (94.67 mg/dL), respectively. ANOVA on data showed significant differences between groups with respect to serum cholesterol at 6 weeks. Statistical analysis of data on various treatments revealed non-significant effect on weight gain but significant effect on feed consumption and FCR. Statistical analysis also revealed non-significant effect of treatments on the average value of dressing percentage, liver, heart, gizzard, spleen and pancreas weight but significant effect on intestinal weight, abdominal fat pad weight, antibody titre against ND and IBD and serum cholesterol level. Maximum profit was found in treatment C (Rs.30.57) followed by treatment D, B and A i.e., 23.02, 22.11 and 28.16 rupees, respectively.
