Effect of FYM, mineral and biofertilizer NP on dry weight and yield of tomato grown in sandy soil [electronic resource].

Includes references.

This investigation was conducted during the two summer seasons of 2003 and 2004 at El-Khattara Experimental Farm, Fac. Agric., zagazig University, to study the performance of tomato cv. Castle Rock in relation to FYM levels (20 and 40 ml/fed) and seven different combinations between mineral N (30, 60, 90,120 kg /fed), mineral P (12,. 20, 28, 80 kg P2O5 fed) and biofertilizer treatments (nitrobein (Nr) and phosphorein (pr) as mixed fertilizer at 0.4 and 0.6 kg/fed, respectively). Application of 40 ml FYMJ/ed stimulated, generally, the growth of tomato plants expressed as dry weight of different plant organs and enhanced photosynthetic p!rments as well as the yield and its components compared to 20 m FYMIfeddan. In spite of that, an adverse effeet was found on carotenoid content compared to 20 m3 FYMlfeddan. The application of 7S % Nand 3S % P2O5 of recommended dose plus inoculation of tomato transplants with biofertilizers (Nr+Pr) and / or 100 % of recommended mineral NP were the most favourable treatments for growth expressed as dry weight of different plant organs and total chlorophyll content in tomato leaves and yield and its components, except average fruit weight. Generally, inoculation of tomato transplants with Nr+Pr combined with 7S % Nand 3S % P2O5 of recommended fertilizer or 100 % of recommended mineral NP without Nr+Pr combined with 40 m3 FYMI/ed were considered the proper interaction treatments which showed the best dry weight, total chlorophyll and yield and its components of tomato plants unde." sandy soil conditions compared to other interaction treatments.
