Description An experiment entitled “Studies on the feasibility oforganic farming in guava (Psidium guajava L.) cvs.
Allahabad Safedaand Sardar” was conducted at the Regional Horticultural Research
Station, Navsari Agricultural University, Navsari during the year2005-2006 and 2006-2007. The
experiment consisting three factor viz.variety (Allhabad Safeda and Sardar), manures (FYM, castor cake,
biocompost, vermicompost and recommended dose of fertilizers)and biofertilizers (no biofertilizers and
biofertilizers) treatmentswhich were replicated thrice in a randomized block design with
factorial concept. Thus total twenty treatment combinations werestudied. The entire quantities of
organic manures were applied ontheir dry weight basis for considering the 500 g nitrogen
requirementof the tree per year. Recommended dose of fertilizers was applied as40 kg FYM and 500-
250-250 g NPK/tree. Application of Azotobacterand Phosphorus Solubilizing Bacteria each 100 g/tree
was applied inthe first week of June after pruning. Manures and recommended doseof fertilizers were
given in the third week of June except nitrogenfertilizer which was applied in two splits, first in third
week of Juneand second in October.The vigorous growth in terms of plant height and plant
spread were noted in Sardar variety while earlier stem circumferenceand 50 % flowering was noted in
Allahabad Safeda variety. Thehighest fruit weight, fruit firmness, fruit volume, fruit diameter andshelflife
of fruits were also recorded in this variety. The higherheight, photosynthetic rate, number of fruits
and yield were recordedin Sardar variety of guava. The better quality fruits in terms of TSS,vitamin-C,
reducing sugars, non reducing sugars and total sugars wereobtained from Allahabad Safeda variety of
guava as compared toSardar. The leaf nutrient contents like iron and manganese werereported higher in
Allahabad Safeda while nitrogen, phosphorus andcopper were maximum in variety Sardar. The highest
available P2O5,K2O, S, Cu, Mn and Zn content were reported in the soil in whichAllahabad Safeda
variety was grown.The vigorous growth was noted in the guava trees
receiving castor cake (M3) and biocompost (M4) while earliness in 50

% flowering and 50 % harvesting were recorded in the guava treesreceiving FYM (M2) and biocompost
(M4), respectively. Themaximum average fruit weight and fruit volume were reported in the
guava trees receiving biocompost (M4 ) while the highest fruit lengthwas noted in the guava trees
receiving castor cake (M3 ). However,yield in terms of number and weights of fruits per hectare were
notedsignificantly the highest in the trees fed with vermicompost. All themanurial treatments produced
better quality fruits of guava ascompared to recommended dose of fertilizers (RDF). The
maximumphotosynthetic rate and soil respiration rate were recorded in thetrees fed with biocompost
(M4) and FYM (M2), respectively.Significantly the maximum leaf nitrogen and sulphur content
werenoted in guava trees fed with vermicompost (M5 ) whereas maximumleaf phosphorus and
potassium content were recorded in the leaf oftrees fed with the manures FYM (M2) and biocompost
(M4),respectively. The maximum leaf copper and iron content reportedwith the application of
biocompost (M4) whereas the maximum leafmanganese content were registered in the leaf of guava
trees withFYM (M2) application. The maximum available nitrogen content inthe soil was reported where
the guava trees fed with castor cake (M3).While available soil nutrients like P2O5, K2O, S, Cu, Mn and Zn
wereregistered where the guava trees fed with biocompost (M4).Significantly the maximum Fe, organic
carbon and water holdingcapacity in the soil were observed where the guava trees fed with
FYM (M2).Guava trees supplied with biofertilizers (B2) showedmaximum average fruit weight, fruit
firmness, number of fruits/treeand yield. However, the guava trees receiving no biofertilizers (B1)noted
significantly the maximum photosynthetic rate and soilrespiration rate. Iron and manganese content in
leaf and availableP2O5 content in the soil were reported maximum in trees fed withbiofertilizers,
Azotobacter and PSB (B2).The Sardar guava receiving 60 kg FYM along withbiofertilizers (Azotobacter
and Phosphorus Solublizing Bacteria) eachat 100 g/tree (V2M2B2) gave the maximum net reliazation
(Rs. 104104/ha).
