| dc.description.abstract | The research project entitled ‘Standardization of organic nutrient schedule for chilli (Capsicum annuum)’ was conducted at Instructional Farm attached to the College of Agriculture, Vellayani during the kharif season of 2012 to standardize the organic nutrient schedule for chilli and to work out the economics. The investigation was laid out as factorial experiment in Randomized Block Design (RBD) with three replications. The treatments consisted of three levels of FYM - F1 (20 t ha-1), F2 (15 t ha-1) and F3 (10 t ha-1) and three levels of substitution of the recommended dose of nitrogen. The levels of substitution are N1 (100 % recommended dose of N- 75 kg ha-1), N2 (75 % recommended dose of N -56.25 kg ha-1) and N3 (50 % recommended dose of N - 37.5 kg ha-1). FYM along with neem cake in 1: 1 ratio is used as organic manure for N substitution. Three controls were also tested in this study. Thèse controls are C1 (KAU POP recommendation -.FYM@ 25 t ha-1 along with75:40:25 kg N:P2O5:K20 ha-1 as inorganic fertilizer), C2 ( KAU Adhoc organic POP recommendation -FYM @25 t ha-1 + Poultry manure at 5 t ha-1 + Pseudomonas + Trichoderma and PGPR mix 1, each @2.5 kg ha-1) and C3 (Farmers practice - Cow dung slurry @ 20 t ha-1) Result of the study revealed that FYM @ 20 t ha-1 recorded significantly higher plant height, no of branches & LAI. The maximum value for all growth parameters were observed at 100% level of N substitution .Combined application of FYM @ 20 t ha-1 along with 100% substitution of recommended dose of N (75 kg ha-1) in organic form registered maximum plant height, branches, LAI, and root spread .This treatment was on par with KAU POP and Adhoc organic POP Maximum yield was recorede at the highest level of FYM (20 t ha-1). Yield contributing characters were also significantly higher at this level. Among the levels of substitution 100% substitution recorded maximum productivity. Application of FYM @ 20 t ha-1 along with 100 % recommended dose of N (75 kg ha-1) as organic form gave maximum productivity which was on par with the yield realized from KAU Adhoc organic POP and KAU POP. Highest level of FYM @ 20 t ha-1 and 100 % substitution of recommended dose of N recorded maximum ascorbic acid, capsaicin content and shelf life. FYM @ 20 t ha-1 along with 100% of substitution of N as organic recorded maximum capsaicin content which was on par with KAU POP recommendation. Ad hoc organic POP recommendation of KAU recorded maximum ascorbic acid content. KAU POP recommendation registered significantly higher N and K uptake than other treatments. Adhoc organic POP recommendations of KAU recorded highest soil pH and organic carbon content. Available nitrogen status of soil was significantly higher in Adhoc organic POP recommendations of KAU but P and K status were on par to KAU POP. Highest B:C ratio and net income were realized in KAU POP. Best nutrient schedules for realising maximum yield from organic chilli is 1) FYM @20 t ha-1 along with 75kg N ha -1 applied through a combination of FYM and neem cake in 1 : 1 ratio + Pseudomonas + Trichoderma and PGPR mix 1, each @2.5 kg ha-1 and 2) Adhoc POP recommendation of KAU -FYM @ 25 t ha-1 along with poultry manure @ 5 t ha-1 + Pseudomonas+Trichoderma and PGPR mix 1, each @2.5 kg ha-1. Economic nutrient schedule for organic chilli is application of FYM @ 25 t ha-1 along with poultry manure @ 5 t ha-1 + Pseudomonas + Trichoderma and PGPR mix 1, each @2.5 k | en_US |
