Item Agronomy(1982-12) Shama Bhat, K.; Abdul Khader, K.B.Item Agronomy(2007-02-08) Shama Bhat, K.; Abdul Khader, K.B.Item Consumptive use and irrigation requirement of arecanut palm (Areca catechu)(2007-02-08) Mahesha, A.; Abdul Khader, K.B.; Ranganna, G.The water requirements of arecanut palm {Areca catechu L.) in the coastal tracts of Karnataka were estimated based on the evaporative demand of the crop. The crop-water demand was evaluated by using the crop-coefficient and the potential evapo-transpiration values. The potential evapo- transpiration values for the region were computed by modified Penman method using a computer programme on monthly and weekly basis for 1971-85. The depth and quantity of water, the frequency of irrigation and the total number of irrigations required varied from month to month. The requirement of water was more during March-May in arecanut than during other months.Item Consumptive use of water in relation to Cumulative Pan Evaporation (CPE) with and without mulching in arecanut(2007-02-08) Abdul Khader, K.B.; Havanagi, G.V.Mulching reduced the consumptive use of water during dry months with increase in yield. Optimum water requirement and frequency of irrigation were worked out based on evapotranspiration and open pan evaporation rates. Irrigation at IW/CPE ratio of 1 to a cumulative pan evaporation of 30 mm gave maximum yield followed by irrigating at the same ratio to a cumulative pan evaporation of 60mm. Both organic mulch and polythene cover were equally effective; but the latter is prohibitively expensive for wider adoption.Item Distribution of cashew roots in the laterite soils of West Coast of India(2007-02-08) Abdul Khader, K.B.The root distribution pattern of cashew trees grown in the West Coast tracts of Kamataka was studied at the Central Plantation Crops Research Institute, Regional Station, Vittal. The lateral as well as vertical spread of the roots were determined on dry weight basis. The results revealed that 9787 per cent of thicker roots and 81.27 per cent of fine roots were spread over within a radius of 2m of the tree and 90.84 percentofthickerand53.74 per cent of fine roots were observed from 0-1 m depth. The maximum depth upto which the cashew roots penetrated was 9.5m The results also showed that 512.73g of thicker and 43.73 g of fine roots a re present perm3 of soil volume. The calculated gross weight of thicker and fine roots per tree were 26.02 and 2.22 kgs respectively. The calculated fine roots as a percentage of thicker roots was 8.53.Item Distribution of nutrients in three varieties of cardamom(1981) Abdul Khader, K.B.; Wahid, P.A.; Kasturi Bai, K.V.; Mohammed Syed, A.A.The uptake and concentration of nutrients in different parts of cardamom plants were studied in three important cultivars. Differences were observed in nutrient distribution pattern. In general, cardamom plants were found to accumulate major and secondary nutrients in the order of K> N ·Ca> Mg> P > Na and micronutrients in the order of Mn > Fe >Zn > Cu.Item Drainage and its importance in arecanut(2007-02-08) Abdul Khader, K.B.Item Drip - A new method of irrigation in arecanut(2007-02-08) Abdul Khader, K.B.Item Effect of bio-fertilizers on growth of black pepper (Piper nigrum)(2007-02-08) Bopaiah, B.M.; Abdul Khader, K.B.Item Effect of different intrials of irrigation at different depths of planting Arecanut(Central Plantation Crops Research Institute Regional Station Vittaal 574243., 1978) Leela, M.; Sadanandan, A.K.; George, C.K.; Abdul Khader, K.B.; Yadukumar, N.Item Effect of soil and climate on the productivity of cashew(2007-02-08) Venugopal, K.; Abdul Khader, K.B.A review of soil and climate conditions of different cashew growing states in India in relation to the production potential of cashew reveals that a well distributed rainfall during growth and pre-flowering phase (from September to November) favours a higher yield potential. Brown forest soil or a deep well drained laterite soil with high water holding capacity and rich in organic matter content appears to be an ideal soil type for better growth and higher productivity of cahsew, while the eroded laterites and coastal sands appear to be poor soil types. The yield potential of cashew is very low under saline/alkaline conditions of the soil and soil water. The cyclonic storms along the East Coast resulting in heavy rainfall, floods and waterlogging also seriously affect the productivity of cashew. Augmenting supplemental irrigation facilities in the rain deficit regions coupled with appropriate soil conservation and fertility management practices are essential in raising the cashew productivity.Item Gas exchange characteristics of cocoa grown under arecanut in response to drip irrigation(1996) Balasimha, D.; Abdul Khader, K.B.; Ravi BhatItem The Influence of Drip Irrigation and Fertilizer Levels on Yield and Photosynthetic Characteristics of Cocoa in Mixed Cropping System with Arecanut(2007-02) Abdul Haris, A.; Balasimha, D.; Sujatha, S.; Ravi Bhat; Abdul Khader, K.B.A study was carried out to determine the influence of drip irrigation and fertilizer levels on the bean yield and photosynthetic characteristics of cocoa mixed cropped in arecanut. The trial was laid out in a split plot design with three irrigation levels as main plot and four fertilizer levels as sub-plot treatments. Four year data after yield stabilization revealed that drip irrigation @ 20 litres of water per tree per day and a fertilizer dose of 100 g N:40 g P2O5: 140 g K2O per tree per year would be optimum for cocoa. This was also supported by better photosynthetic characteristics.Item Influence of Mulches on Soil Microflora with Different Levels of Irrigation in Areca Garden(2007-02) Abdul Khader, K.B.; Bopaiah, B.M.Item Influence of Weather on Arecanut And Cocoa Yield(2007-02) Vijayakumar, B.G.; Veerappa Devaru, G.; Balasimha, D.; Abdul Khader, K.B.; Ranganna, G.Regression analysis of weather variables suggested that yield was influenced by relative humidity, pan evaporation and rainfall in arecanut while temperature influenced cocoa yields. In case of arecanut the regression equation explains eighty four per cent of variations in yield. The equation is not a good fit in case of cocoa for predicting yield.Item Inter and Mixed Cropping in Areca Gardens(2007-02) Abdul Khader, K.B.Item Inter and mixed cropping trials 3.
