It’s growing all over the world, like India, USA, Russia, China, Brazil, Pakistan, Egypt, Turkey, and Sudan etc. Cotton is cash crop and Pakistan known as ‘white gold’, cotton contributes 23.60 percent of value added and 4.45 of the total GDP of the country (GoP, 2021). Two third exports earning of the country are from the cotton made-up and textiles, it add $2.5 in national economy while   country textile mills and ginning factories are also depends on cotton (Rani et al., 2017).  Study objectives Identify and compare the training methods for cotton production perceived by cotton farmers, determine the effectiveness of various training methods on cotton farmers' knowledge and skills & Identify barriers to applying knowledge and skills by farmers.  Total sample size were 100 cotton growers purposely were selected from study area. Data collection were collected through well design research questionnaire and data analyzed through (SPSS) statistical software.  It was observed that overall training program had very positive impact on farmer’s knowledge and skills because farmers became aware about filed issue and they started practical work their field to get maximum yield from cotton crop.

The results so far achieved opened further window for deep analysis with reference to functional analysis of soma-clonal variated plants with different approaches. Results on the performance for soma-clonal variation in sugarcane variety NIA-2010 and their soma-clones revealed the best performance of varieties, which showed that the plant height (302.33cm) was observed in SC-3 and the lowest performance was examined in SC-2 that was approximately (154.33cm). The consequences of varieties and diverse parameters indicated that the highest number of internodes plant-1 were recorded (38) in SC-3 and lowest number of internodes plant-1 were accomplished (23) in SC-1.

Therefore, to investigate the effect of co-inoculation of Bradyrhizobium and phosphate solubilizing microbes (PSM) on groundnut crop under field conditions using normal soil, divided into eight different study groups i.e., control (T1), Bradyrhizobium isolate -1 (T2), Bradyrhizobium isolate -2 (T3), Bradyrhizobium isolate -3(T4), Phosphate solubilizing microbe (PSM) (T5), T2 + PSM (T6), T3 + PSM (T7), T4 + PSM (T8).

Appropriate tillage practices together with balanced fertilizer may be a promising practice of soil management to improve soil properties and crop production. The present study was carried out in wheat-maize cropping pattern (in the year 2019-20) at agricultural research farm of Gomal University, Dera Ismail Khan, Pakistan. The experiment was set up in a split-plot layout with a randomized complete blocks design. The nitrogen levels of 0, 90, 120, 150, and 180 kg N ha-1 were assigned to subplots. Tillage and nitrogen treatments separately had a significant impact on growth and yield characteristics, but the interaction between them had minimal effect, according to the findings. The tallest heights were found in the conventional tillage plots and the high N input (N180) plots, with heights of 101 and 104 cm, respectively. The spikes per m2 were found 242 in zero tillage plots, while the highest number of spikes per plot (265) was recorded in N180. The yield contributing factor number of grain spike-1 was 48.7 in zero tillage, while the nitrogen fertilizer @ 180 kg ha-1 yielded 52, 1000-grain weight of 35g was measured in conventional tillage and 38.8g in nitrogen fertilizer plots. Deep tillage where the nitrogen @ 150 kg ha-1 was applied gave the maximum grain yields, with 3113 kg ha-1 and 3415 kg ha-1, respectively.

General combining ability (GCA) mean squares were non-significant for grain yield and its related components. Specific combining ability (SCA) mean squares were highly significant for grain yield, the number of grains per row and cob girth while non-significant for days to tasseling, days to silking, plant height, cob height and cob length. These studies suggested the preponderance of non-additive type of gene action for grain yield, cob girth and number of grains per row and additive gene action for days to tasseling, days to silking, plant height, cob height and cob length. The genotypes MIL2020-51 and MIL2020-52 were good general combiners for grain yield, grains per row, cob height and plant height. These lines were the poorest general combiner for days to 50% tasseling and days to 50% silking which suggested that these genotypes had sufficient genes for inducing earliness.
