Abstract
A field experiment laid out in Completely Randomised Block Design with 13
treatments replicated thrice was conducted during kharif 2010 to study the
biochemical studies on Homa organic farming practices in cabbage (Brassica
oleracea var. Saint). The conventional control (CC) and control without homa (CWH)
were maintained almost 1 km away. The soil type was red black. All the seedlings
were grown on raised beds, transplanted after one month and were given fresh cow
dung and cow urine as basal treatment except absolute control, CC and CWC. The
non-homa ash was collected after burning the agricultural waste. Agnihotra homa
(AH) was performed at sun rise and sun set and Om Tryambakam homa (OTH) was
performed for 3-4 h daily during experimental period. A special bio-digester called
Gloria Biosol was prepared which contained AH ash. The non-homa ash, AH ash,
OTH ash and Gloria Biosol were used for soil and foliar application. Soil and foliar
application of Gloria Biosol was significantly superior over organic control in plant
height, number of outer leaves per plant, leaf area, number of inner leaves per head
and yield attributes, microbial population in soil, increase in the activities of soil
dehydrogenase (15-54%) and soil phosphatase (6-18%), soil N, K, Cu and Mn and
cabbage TSS (41%), ascorbic acid (11%), phenols (18%), crude protein (16%), N
(16%), S (71%), K (22%), P (22%), Cu (13%), Zn (8%), Mn (9%) and Fe (4%)
showed significant increase over organic control. Soil and foliar application of AH
ash significantly increased soil P, Zn and Fe. Significant reduction was observed in
the incidence of black rot (29-55%), black spot of leaf (39-73%), insect attack (head
borer(18-69%), diamond back moth larvae (25-64%) and Spodoptera litura larvae
(40-62%) per plant due to soil and foliar application of Gloria Biosol and different
homa treatments.
