Different Levels of Nitrogenous Fertilizer Application for Growth, Flowering and Yield Attributes of Glori lily (Gloriosa superba L.)

Abstract

Field experiment were conducted at farmer’s field, Devanur village, Ariyalur District of Tamil Nadu during 2008 to study the Different Levels of Nitrogenous Fertilizer Application for Growth, Flowering and Yield Attributes of glori lily. There were Five different treatments viz., Control (T0), 100 per cent recommended N (T1), 75 per cent recommended N (T2), 50 per cent recommended N (T3) and 25 per cent recommended N (T4). The treatments were replicated four adopting RBD design. The growth and yield attributes of glori lily viz., plant height, leaf area index, number of primary branches plant-1, number of secondary branches plant-1, number of tertiary branches plant 1,drymatter production (kg ha-1), days to fifty per cent flowering, number of pods plant-1, number of seeds pod-1 and hundred seed weight (g), were favorably increased by the application of 100 per cent recommended N (T1). Seed and tuber yield (Kg ha-1) were greatly increased and the maximum seed and tuber yield were recorded. The uptake of NPK by glori lily was significantly increased by the above treatment combination. Application of 100 per cent recommended N (120 kg ha-1) (T1) gave the highest Gross income, Net income and return per rupee invested. Based on the above results, it can be concluded that inorganic use of 100 per cent recommended N (120 kg ha-1) is found to be an appropriate agro-technique for augmenting the productivity and profitability of glori lily without altering the soil fertility. It is a basic constituent in all proteins, enzymes, chlorophyll, certain parts of nucleus and hormone. The supply of nitrogen is related to carbohydrates utilization for growth and development process.
