Abstract

An investigation was undertaken to study the effect of foliar sprays of NAA, triacontanol and boron on vine growth, seed quality and storability in bitter gourd cv. Pusa Visesh. Results revealed that NAA at 50mg/l produced the longest vines (192.33 and 260.67cm), maximum leaf area (1.890 and 2.965cm²/vine), leaf area index (1.969 and 2.760) and leaf chlorophyll content (39.23 and 38.90 SPAD value) at 85 and 100 days after sowing (DAS), respectively. As for seed quality attributes, treatment with boron at 4mg/l recorded lowest seed moisture content and highest seed germination percentage (9.16% and 85.5%, respectively), followed by NAA at 50mg/l (9.21% and 85.25%, respectively) whereas, Control recorded highest seed moisture and lowest seed germination percentage (9.84% and 74.5%, respectively) recorded at the end of storage.

Abstract

To study stability of genotypes under three diverse environments, ten genotypes along with two checks of processingtype tomato were evaluated in Randomized Block Design (RBD) with three replications. Environment included three seasons, viz., kharif (2007), rabi (2007-08) and summer (2008) to identify the most stable varieties. Overall performance of PTR-1, PTR-4, PTR-6 and 'Arka Ashish' was found stable for yield per plant, number of branches per plant, % fruit set, % acidity and lycopene content. PTR-4 and PTR-6 were stable for high yield and for good processing traits.
