 ABSTRACT

An experiment was carried out  to study the effect of soil and foliar application of calcium, magnesium and boron on growth, yield and quality of cabbage. The result revealed that application of calcium and  boron as foliar spray  and magnesium  as soil application recorded the maximum plant height (37.12 cm), number of leaves per plant (32.66), plant spread (59.21 cm), leaf area (699.12 cm²) ,  minimum number of days to head formation (50.66 DAT) and head maturity (85.33 DAT) in cabbage .The highest available Mg (215.66 mg kg^-1) and  available S (11.69 mg kg-1 ) in soil, N content in leaves (2.28 %) and  cabbage head (2.21 %), Ca content (2.42 % ) in  leaves and in cabbage head (0.99 % ) were  obtained in the same treatment. With regard to  nutrient uptake also the same treatment recorded the highest  uptake of  N (1.912 g plant ^-1 ), Ca (1.112 g plant ^-1),Fe ( 0.299 g plant ^-1 ) and Mn (0.434 g plant ^-1 ). The highest fresh  weight of plant (1.833 kg), head yield ( 1.216 kg) and the quality parameters like  protein content (1.93 % )and vitamin C content(  64.55 mg ^-1 100 g ) were  obtained due to the  soil application of Mg and  foliar spray of B and Ca . The highest B: C ratio (1.82)  was registered by the same treatment and was found to be significantly superior. This treatment effect has registered the highest nutrient use efficiency for Ca (42.55 g pot ^-1) and B (85.66 g pot ^-1). The highest available boron in soil of 1.32 mg kg^-1  and  available nitrogen  of 397.22 kg ha ^-1  were observed in treatment receiving soil application of Mg and B and foliar spray of Ca. The  content and uptake of P , K , Mg  and B  in cabbage were found to be the highest in treatment receiving soil application of Ca and foliar spray of Mg and B. The highest sulphur content in leaves (0.43%) and head (0.34 %) and also uptake of 0.283 g plant ^-1  were obtained in treatment receiving soil application of Ca and B and  foliar spray of Mg. The foliar application of Ca, Mg and B increased the chlorophyll content in leaf (5.39 mg g ^-1)  at heading stage  and  nutrient use efficiency for Mg (27.81 g pot ^-1).
