Influence of Dates of Sowing and Fertilizer on Growth and Seed Yield of Sunnhemp Genotypes
Journal Title: International Journal of Research in Agricultural Sciences - Year 2018, Vol 5, Issue 3
Abstract
A field experiment was conductedduring kharif2016, to study the effect of date of sowing and fertilizer application on seed yield and quality of Sunnhemp genotypes (Crotalaria juncea L.)at Agricultural Research Station, Kalloli,Gokak taluk Belagavi district, University of Agricultural Sciences, Dharwad.The field experiment comprised of twenty four treatments with three replications in double split plot design.Among different dates of sowing,D3-First fortnight of August registered less days to flower initiationand 50 per centflowering(36.22and 55.50days respectively) followed by second fortnight of July (D2-38.20and 60.62days respectively) and more number of days were shown in first fortnight of July (D1-40.12and 65.62daysrespectively). With respect tofertilizer levels, F1-25:50:25 NPK kg ha-1recorded less number of days for flower initiationand 50 per centflowering(36.58 and 57.07 daysrespectively) followedby F2(38.01 and59.91daysrespectively)and F3( 39.95and 64.76daysrespectively). D3-first fortnight of August was recorded significantly higher seed yield per plot (1.04 kg) than D2-second fortnight of July (0.97 kg) and D1-first fortnight of July(0.90 kg). Fertilizer levels had a significant influence on seed yield per plot. Higher fertilizer level,F3-37.5:75:37.5 NPK kg ha-1recorded significantly higher seed yield per plot (1.04 kg) than F2-31.25:62.5:31.25(0.99 kg) and F1–25:50:25 NPK kg ha-1(0.87 kg). Higher seed yield per hectare was recorded in D3-first fortnight of August (1,798 kg) as compared to the D2and D1(1,686 and 1,569 kg respectively). Among the fertilizer level, F3-37.5:75:37.5 NPK kg ha-1recorded significantly higher seed yield per hectare (1,808 kg) than F2-31.25:62.5:31.25 NPK kg ha-1and F1–25:50:25 NPK kg ha-1(1,727 and 1,517 kg respectively).
