Abstract

The experiments was carried out to study the effect of spacing, planting methods and mulching on growth and floral parameters in gladiolus (Gladiolus hybridus L) cv. American Beauty at the Department of Horticulture, University of Agricultural Sciences, GKVK, Bangalore during both Kharif and Rabi seasons of 2007-08 and 2008-09. The experiments consisted of eight treatments with three replications were carried out by Randomized Complete Block Design. The experiment comprised of single row 30 x 20 cm and 40 x 20 cm with mulching and no mulching and double row 30x 20 x 60 cm and 40 x 20 x 80 cm with mulching and no mulching. The present investigation reveals that, there was an improvement in the growth and floral parameters in gladiolus in 30 x 20 cm spacing with mulched plots treatments. Improved growth, flower yield and corm yield were observed in plastic mulched plots irrespective of different levels of spacing, planting methods adopted.

Abstract

A field experiment was conducted to find out the suitable tamarind based intercropping systems under irrigated situation at Kittur Rani Channamma College of Horticulture, Arabhavi, Gokak, Belgaum (district), Karnataka. Eleven intercrops viz., ajowan, ashwagandha, brinjal, carrot, chilli, coleus, garlic, ginger, lab lab bean, safed musli and turmeric were evaluated for their performance both under intercropping and sole cropping situations. The yield of the intercrops varied significantly between intercropping and sole cropping. Tamarind based intercropping system with safed musli recorded the highest net income (Rs. 3.152 lakh/ha) while the highest benefit cost ratio was obtained in tamarind + ginger cropping system (4.40) followed by tamarind + turmeric (2.49).

Abstract

Interception of photosynthetically active radiation (PAR) in tamarind (8 year old) based intercropping systems compared to sole cropping in open area was studied at Kittur Rani Channamma College of Horticulture, Arabhavi, Belgaum district, Karnataka. The interception of PAR by all the crops was higher under sole cropping throughout the stages of growth when compared to tamarind based intercropping system. At 120 DAP, turmeric intercepted the highest PAR (39622 lux) among sole crop followed by coleus (38346 lux). Similarly, under intercropping situation also, turmeric intercepted the higher PAR (30713 lux) followed by chilli (28864 lux).
