Rewa (M.P.) was carried out during the Kharif season of 2009-10 under the edaphic and climatic condition of Rewa (M.P.). Significant variation was observed in growth and yield attributes are use interaction effect of various planting methods i.e. Flat bed, ridge and furrow and spacing methods 30x20 cm, 45x20 cm. and 60x20 cm. Growth attributes i.e. plant height, number of leaves per plant, length of leaves, breadth of leaves, no of clumps per plant, length of clumps per plant were recorded periodically at 30 days intervals up to 150 days of planting all these parameters were significantly higher with spacing 60x20 cm and ridge bed method of planting. The increasing spacing between rows up to 60x20cm and planting method ridge method encouraged the weight of primary rhizomes, weight of secondary rhizomes per plant and the fresh weight of rhizomes per plant up to significant extent. The maximum weight of primary rhizomes was 24.15 gm, weight of secondary rhizomes 31.65 gm per plant and fresh weight of rhizomes was up to 92.39 gm per plant. The combined influence of ridge bed method with 60 x 20 cm. spacing further augmented this entire yield-attributing parameters synergistically as compared to their separate application.

Nutrients must be accessible at right time, proportion and quantity. Aim and Objective: To fulfill these necessities, chemical fertilizers and organic manures are required in integrated manner. Chemical fertilizers have ensured readily availability of particular nutrient for initial but organic sources release slow and long term availability of many nutrients and they improved the efficacy and reduced the quantity of chemical fertilizers. Materials and Methods: Therefore, fields study was taken up to bridge the gap at department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture, RVSKVV, Mandsaur, (M.P.) during the Kharif season 2021-22 in RBD Design with three replications. The treatments accompanied with RDF NPK @ 50:30:30 kg ha-1 , FYM @ 7.5 & 15 T ha-1 and vermicompost @ 0.5 & 1.0 T ha-1 along with a control plot without any supplements. Results: The result indicated that, the significant maximum plant height, number of branches, number of leaves, leaf area, leaf area index, relative growth rate, crop growth rate, biomass production at different growth stages and number of seeds per pod, pod length, pod dry weight, harvest index, dry herbage yield, seed yield, cost of cultivation, gross return, net return and benefit: cost ratio were observed in treatment T8-100% RDF+100% FYM+100% vermicompost. Conclusion: The treatment T8-100% RDF @ 50:30:30 kg ha-1 +100% FYM @ 15 t ha-1 +100% vermicompost @ 1 t ha-1 is found to be the best for achieving the highest growth and yield of kalmegh.

Kiesser is serious aerial disease, commercially grown Asalio crops (Lepidium sativum L.) in western Madhya Pradesh of India. The present study investigated the effect of temperature, relative humidity and rain fall during 2009-10. Relative humidity is found to be 42.42% minimum and 84.14% maximum an average 63.28%, temperature 4.9 °C minimum and 29.14 °C maximum an average 17.02 °C and rain fall 20.0 mm, these indicate that moderate temperature high humidity and moderately rainfall are favorable for the development of leaf and stem spot disease on Asalio.

Nitrogen (87 kg, 110 kg and 133 kg/ha), Potassium (0, 34.5 kg, 69 kg and 103.5 kg/ha) and potato varieties (Betete, Gudenie and Jalenie) were used. Data were analyzed by using SAS software Version 9.2. The interaction effect of potassium and nitrogen fertilizers did affect marketable tuber number and plant height significantly. Gudenie produced the highest marketable yield (30.53 ton/ha) in 2015 with application of 69 kg/ha potassium and 110 kg/ha nitrogen rates while lowest marketable yield (16.67 ton/ha) was obtained from Belete variety at 0 kg/ha potassium rate and 87 kg/ha nitrogen rate. From these results, it can be concluded that interaction of nitrogen and potassium rates affected significantly plant height and marketable tuber numbers. Therefore, it is better to apply 69 kg/ha potassium and 110 kg/ha nitrogen for potato production to obtain reasonable economic yield at sites similar to experimental locations.

The experiment conducted in Randomized Block Design with three replications using cv. Arka chandan, with ten treatments, two kinds of organic manures (FYM and Vermicompost) alone and in combination with two kinds of biofertilizers (Azotobacter and PSB) and reduced doses of chemical fertilizers were tested in comparison with RDF. On the basis of results, the application of 50:25:25 Kg NPK ha-1 + FYM 25 t ha-1 + seed treatment with PSB to the crop found to be sound integrated practice. The integrated use of inorganic fertilizers, organic manures and biofertilizers had a significant effect on nutrient uptake. The highest uptake of Nitrogen, Phosphorus, and Potash by pumpkin vine was recorded maximum in the treatment 50 kg N, 25 kg P 2 O 5 , 25 kg K 2 O ha-1 dose of fertilizers in combination with FYM 25 t ha-1 and seed treatment with PSB 25 g kg-1 of seed. i.e. T 4. Available Nitrogen, Phosphorus and Potash in the soil after harvest of pumpkin crop were highest in the treatment with application of inorganic fertilizers 50 kg N, 25 kg P 2 O 5 , 25 kg K 2 O ha-1 in combination with FYM 25 t ha-1 and seed treatment with PSB 25 g kg-1 of seed. i.e. T 4 recorded maximum Nitrogen, Phosphorus, Potash (190.23, 27.97, 386.91 kg ha-1 respectively).
