KIRAN KUMAR of Nitrophen 4%, Nitrogen compound 12%, Iron 2%, Magnesium 2%, Manganese 2%, Boron 2%, Copper 4%, Molybdenum 2%, Potash 8%, P 2 O 5 12% and Calcium 8%. Similar studies have also been conducted by Jiskani (2005), who found that foliar application of zinc 3.0 ppm, copper 1.0 ppm and boron 0.5 ppm produced the highest number of fruits per plant and increasing frequency of NPK (19:19:19) spraying from three to four times did not increase the number of chilli fruits per plant. Increased yields due to foliar spray could be attributed to the reason that foliar feeding is often effective when roots are unable to absorb sufficient nutrients from the soil and such a condition could arise from an infertile soil, a high degree of soil fixation, losses from leaching, soil temperatures, lack of soil moisture, or restricted, injured or diseased root system. Further, Silberbush (2002) also reported that foliar fertilization is a widely used practice to correct nutritional deficiencies in plants caused by improper supply of nutrients to roots. Improvement in yield of chilli was evident with increase in NPK 19:19:19 concentration. However, application beyond 7.5 g l -1 water was not effective and thus 7.5g l -1 water along with KNO 3 @ 5g l -1 was considered to be an optimum concentration for commercial production of Chilli.

J.Res. ANGRAU 41(1) 5-13, 2013 NUTRIENT UPTAKE BY RICE CROP UNDER LONG TERM INTEGRATED NUTRIENT MANAGEMENT IN RICE – RICE CROPPING SYSTEM IN ALFISOLS V. MAHESWARA PRASAD and P. PRABHU PRASADINI DAATT Centre, Krishna District, Machilipatnam – 521 002 Date of Receipt : 07.12.2012 Date of Acceptance : 31.01.2013 ABSTRACT Nutrient uptake by rice crop in different integrated nutrient management treatments at different stages of crop growth in rice-rice cropping system was studied in alfisols of Southern Telangana Zone of Andhra Pradesh for two consecutive years during 2005-06 and 06-07. The crop fertilized with increased level of nutrients accumulated more phytomass at every stage of sampling in kharif or rabi seasons during the two years. The uptake of NPK, Zn, Cu, Fe and Mn was also maximum in response to the application of recommended dose of fertilizers. There was no definite increase in the phytomass or uptake of major or minor nutrients consistently throughout the crop growth period during the two years by the integrated nutrient supply system compared to the application of recommended dose of fertilizers. India is one of the main countries producing Rice (Oryza sativa L.) in the world. Rice –Rice is the most predominant cropping system in southern telangana zone of Andhra Pradesh state. Deterioration of soil fertility and declining productivity due to indiscriminate application of nutrients through the fertilizers with the threat of the declining productivity has become major problem. Continuous cropping and long term fertilization are liable to change the soil properties and crop production, depending upon the type of management practices (Santhy et al, 1998). The micronutrient deficiencies are being recognized in soils intensively cultivated with cereals in several parts of the country. This is aggravated by the continuous application of high analysis fertilizers without replenishing the depleted micronutrients. Therefore, the incorporation of organic material is emphasized to supply the micronutrients and thereby maintain the nutrient balance. Hence, an investigation was made to assess the soil nutrient supplying capacity under different INM practices in a long-term fertilization experiment with continuous rice - rice cropping system. MATERIALS AND METHODS The present studies were conducted during two consecutive years 2005-06 and 2006-07 at Agricultural College Farm, Rajendranagar, Hyderabad. The experiment was conducted on a sandy clay loam soil on which only rice is grown continuously in both kharif and rabi seasons since 1988. The experiment was laid out in randomized block design with 12 treatments (Table 1) in three replications. Rice variety RNR 23064 was planted adopting a spacing of 20 cm x 10 cm in 59.8 m 2 sized plot. Sampling of plants was done by uprooting five hills per treatment at tillering, panicle initiation and harvesting stage of the crop in each season during the two years of the investigation for the nutrient removal studies. The samples were ground using Willey mill and extracted with triacid. The resultant extract was subjected to analysis of N.P and K as per the procedures outlined in Tandon (1995). Finally, the uptake of macro nutrients was calculated by using the following formula; Nutrient uptake (kg ha -1 ) = nutrient content (%) x dry matter (kg ha -1 ) divided by 100. Whereas the uptake of micro nutrients was calculated by using the formula; Nutrient uptake (g ha -1 ) = nutrient content (%) x dry matter (g ha -1 ) divided by 100. RESULTS AND DISCUSSION Major Nutrients a. Nitrogen The crop grown without the external input of manures and fertilizers removed lesser quantities of 26, 35, and 63 kg N ha -1 in kharif 2005 at tillering, panicle initiation and harvesting stage of the crops email: vemulamadamp@gmail.com 9
