Description |
A field expe_riment was conducted on a sandy loam soil (Alfisol, locally known as chalka soil) at the Student Farm, College of Agriculture, Rajendranagar, Hyderabad during rabi, 1991-92 to study the integrated affect of application of different levels of fertilizer_f0:0:0; 60:30:30 and 120:60;uU N, P2o5 and K2Q1 kg ha and poultry manure (0, 1.5, 3.0, 4.5 t ha ) on available nutrient status in soil at various crop growth stages, nutrient composition and uptake, growth characters, dry matter and grain and stover yield of maize. The experiment was laid out in factorial randomised block design, replicated thrice. DHM- 103 Hybrid was used for the study. The poultry manure collected from different locations has shown that it is a potential source of plant nutrients like N, P, Kand micronutrients. Germination of maize seeds was not affected by either poultry manure or fertilizer application to soil. However, the treatment 120 : 60: 60 N, P2o5 and -1 K2o. kg ha with no poultry manure addition gave the maximum germination of maize seeds (95.00). Available nutri8nts (N, P, K, Fe, Mn, Cu and Zn) status in the soil significantly increased with increasing the fer~flizer doses, upto 120:60:60 ~l PO o and KO kg ha , poultry manure upto 4.5 t ha an~1their in~eractio~1of 120:60:60 N, P2o5 and K2o kg ha plus 4.5 t ha poultry manure. Tfie nutrients status also increased with the age of crop and were maximum at harvest. nutrient increased increased manure or The nutrient composition in whole plant and uptake (N, P, K, Fe, Mn, cu and Zn) were with the age of crop and also significantly with increasing t .. a fertilizers or poultry their interaction. The growth characters viz., plant height, cob weight, 1000 grain weight and dry matter yield was significantly incr~_.sed with increasing the levels of fertilizer~ and poultfY manure upto 1~2: 60: 60 N, P2o5 and K2o kg ha and 4.5 t ha individually. Tfieir interactfon, was maximum1at 120: 60: 60 N, P20~ and Ko kg ha plus 4.5 t ha of poultry manure whlct was oi par with the similar N,P,K levels 2fd 3.0 t haan9160 : 30 : 30 N, P2o5 and K2o kg ha plus 4.5 t ha of poultry manure ereatments. Th ~s showed that the fertilizer dose and poultry me~ure combinatiog1 of 60 : 30 :30 N, Po and Ko kg ha plus 4.5 t ha of poultry can be pr3fitably idopted for maize. Grain and stover yields were also significantly increased with increasing the fertilizer or poultry manure or both. The grain and st~ver yields -!ere maximum at 120 : 60 : ~2 N, P2o5 and K20 kg ha of fertilizer, at 4.5 t ha of poulery manure individually and th~fr interaction 2f 120 : 60 . 60 N, P20~ and K2o kg ha plus 4.5 t ha of poultry manure whigr was on par wi~~ 120 60 : 60 N, P2o5 and K20 kg ha pl~! 3.0 t ha and_16o : 30: 30 N, P2o5 and K2o kg ha plus 4.5 t ha of p~yltry manure. Hence, the treatment 60:30:30 kg ha ~f N, P2o5 and K20 plus poultry manure @ 4.5 t ha was recommenaed for optimizing the maize yields by conjuctive use of poultry manure and fertilizers as this treatment gave a highest net profit of Rs.6244/- over control compared to other treatments. |
