Pengaruh Kombinasi Berbagai Dosis Pupuk Anorganik N,P,K Dengan Pupuk Organik Terhadap Pertumbuhan Dan Produksi Tanaman Padi Sawah (Oryza Sativa L.)
ABSTRACT
The aim of the study was to obtain the best combined dose of inorganic fertilizers N,P,K and organic fertilizers for the growth and production of paddy rice (Oryza sativa L.) so as to reduce the use of inorganic fertilizers. The study used a non-factorial Completely Randomized Design (CRD). The treatments used were: 100% inorganic fertilizer; 100% inorganic fertilizer + petroganic; 100% inorganic fertilizer + 100% solid compost; 75% inorganic fertilizer + solid compost; 75% inorganic fertilizer + solid compost + biological fertilizer; 50% inorganic fertilizer + solid compost + biological fertilizer. Parameters observed were plant height, maximum number of tillers, number of productive tillers, crown dry weight, root dry weight, age of panicle exit, harvest age, number of ripe grain per panicle, percentage of full grain, weight of 1000 grain grains, weight of dry milled grain per clump, dry grain weight per 2 m2, and harvest index. From the results of the study it can be concluded that giving the best combination dose, namely the application of 75% inorganic fertilizer N,P,K with 16 ton.ha-1 solid compost and 10 ml.l-1 biological fertilizer has been able to provide the best results for the growth and production of rice plants and can reduce use of 25% inorganic fertilizer.
