摘要

A field experiment was conducted from 2011-12 to 2013-14 at Agricultural Research Station, Kota, Rajasthan, to find out suitable nutrient-management practices for sugarcane (Saccharum officinarum L.). The experiment was consisted of 13 nutrient management practices, viz. control, N_(200), N_(200)P_(60), N_(200)P_(60)K_(40) (RDF), N_(200)P_(60)K_(40)+S_(40) N_(200)P_(60)K_(40)+Zn_5, N_(200)P_(200)K_(40)+Fe_1, N_(200)P_(60)K_(40)+ Mn_1, N_(200)P_(60)K_(40)+S_(40)+Zn_5, N_(200)P_(60)K_(40)+S_(40)+Zn)5+Fe_1, N_(200)P_(60)K_(40)+S_(40)+ Zn_5+Fe_1+Mn_1, N_(150)P_(50)+ S_(25)+Zn_4 kg/ha as soil-test recommendation (STR) and FYM @ 20 t/ha were laid out in randomized block design with 3 replications. Balanced fertilization of N_(200)P_(60)K_(40) along with S_(40)+Zn_5 kg/ha had significant influenced on tillers, number of millable canes (126,060/ha), single cane weight (880 g), cane yield (91.70 t/ha), commercial cane sugar yield (11.96 t/ha) and net profit (RUS 90,974/ha) over rest of the treatments beingon a par with treatments of N_(200)P_(60) K_(40)+S_(40). N_(200)P_(60)K_(40)+Zn_5, N_(200)P_(60)K_(40)+Fe_1, N_(200)P_(60)K_(40)+Mn_1, N_(200)P_(60)K_(40)+S_(40)+Zn_5+Fe_1, N_(200)P_(60)K_(40)+Zn_5+Fe_1+Mn_1, N_(150)P_(50)+S_(25)+Zn_4 kg/ha. Maximum nutrient uptake of N, P and K (265.3, 21.3 and 260 kg/ha) was recorded with application of N_(200)Pg^K^^+S^^j+Zn^ kg/ha over rest of the treatments and It was observed higher positive net gain of N, P, K and S (8.5, 3.4, 16 and 3.7 kg/ha) was recorded overInitial status of soil. The result showed that balanced application of N_(200)P_(60)K_(40)+S_(40)+Zn_5 kg/ha may be recommended for obtaining higher millable cane yield, net return and sustained soil health In spring planted In clay loam soils of Rajasthan.
