Productivity and photosynthetic pigments in bell pepper plants grown in soil with biofertilizer and protected against water loss

The search for techniques that maximize the use of water is becoming necessary sustainability agriculture in semi-arid areas. In this sense, present work aimed to evaluate effects soil protection against loss and bovine biofertilizer on fruit production chlorophyll content bell pepper plants. experiment was conducted municipal district Nova Floresta region State Paraíba during period August 2010 February 2011. experimental design a randomized block with four repetitions 2 × factorial scheme, corresponding without biofertilizer, mulch, side coating grooves polyethylene film, reduce through evaporation lateral movement water. results showed coatings led greater production, generating productivity gains cultivation. association between mulching resulted increased levels chlorophyll, but mulch interaction inhibited
