    Evaluation of establishment methods and AMF application on growth and yield of rice
    (Department of Agronomy, College of Agriculture, Vellayani, 2004) Jayakiran, K; Sajitharani, T
    An experiment was conducted at College of Agriculture, Vellayani during kharif season (June - September 2003) to evaluate the efficiency of different planting methods and AMF application en the establishment, growth and yield attributes of rice. The experiment was laid out in split plot design with five replications. The main treatments were seedling , throwing, machine planting and line transplanting methods. The subplot treatments consisted of AMF application and without AMF application. Maximum establishment as noticed in line planting. More root activity, plant height, leaf area index, dry matter production and tillers were observed in seedling throwing method. Days to 50 per cent flowering was minimum in machine planting. Higher number of filled grains per panicle was observed in line planting. Higher number of productive tillers, panicles m-2 and straw yield was observed in seedling throwing method. Higher grain yield was observed in seedling throwing and line planting methods. Maximum harvest index was noticed in line planting. Higher uptake was noticed in seedling throwing method. AMF inoculated plants show~d supenor trends in establishment plant height, leaf area index, drymatter production, number of productive tillers, panicles m ", filled grains panicle.", 1000 grain ,eUEbt. grain yield and straw yield. Higher gross return and net return was observed in seedling ing method. In machine planting and see~ling throwing there was high labour saving compared to line planting .. High B : C ratio, gross turn and net return were observed in AMF inoculated plants. Machine planting of seedlings raised in AMF inoculated mat nursery, at a spacing of 30 x 10 cm followed by seedling throwing of MF inoculated seedlings recorded higher B : C ratio.

    Standardisation of fertilizer schedule for export oriented production of bhindi
    (Department of Agronomy, College of Agriculture, Vellayani, 1993) Sajitharani, T; Pushpakumari, R
    An experiment was conducted at the instructional farm, College of Agriculture, Vellayani to find out the effect of different levels of fertilizers and their split application on the growth, yield, quality and nutrient uptake of bhindi. Abelmoschus esculentus (L) Moench. The treatments consisted of four levels of nutrients Viz. (330: 110: 220 kg N2 P2O5 & K2O), the present T & V recommendation, 2/3 of the T & V recommendation, 1/3 of the T & V recommendation and 50: 8: 30 kg NP2O5 & K2O per hectare the present package of practices recommendation and 3 methods of application viz. nutrients in 2 splits, 4 splits and 6 splits. The results revealed that nutrient levels significantly influenced most of the growth and yield contributing characters and yield of bhindi. Biometric characters like plant height, LAI, CGR, DMP and yield contributing characters like days to 50 percent flowering, number of flowers formed, number of fruits formed total yield of fruits and quality parameters like protein content and ascorbic acid content increased with increasing levels of nutrients, recording their maximum value at F1 level, (T and V recommendation). Uptake of nutrients by plants, fruits and total was also maximum for the same treatment. However yield attributes viz. setting percentage, length and girth of fruits etc. remain unchanged with increasing levels of nutrients. Application of fertilizer nutrients in different splits viz. 2,4 or 6 cause significant variation in some of the growth and yield characters. An increase in the plant height at 60 DAS, DMP, days taken for 50 percent flowering and uptake of nutrients was noticed when nutrients were supplied in two equal splits, viz half as basal and half 30 DAS (S1). On the other hand the ascorbic acid content in fruits was maximum when nutrients were applied in six splits. Application of nutrients in 6 splits caused a significant reduction in the crude fibre content also. From the economic point of view, the maximum net profit of Rs.13682.54 was obtained by F3 level (2/3 of T and V recommendation) and Rs.14710.8 by S1 (2 equal splits half as basal and half 30 DAS).
