Abstract A model to predict photosynthetic carbon assimilation rate (A) with high accuracy is important for forecasting crop yield and productivity. Long short-term memory (LSTM), a neural network suitable for time-series data, enables prediction with high accuracy but requires mesophyll variables. In addition, for practical use, it is desirable to have a technique that can predict A from easily available information. In this study, we propose a BLSTMaugmented LSTM (BALSTM) model, which utilizes bi-directional LSTM (BLSTM) to indirectly reproduce the mesophyll variables required for LSTM. The most significant feature of the proposed model is that its hybrid architecture uses only three… More >

Abstract The aim of this study was to evaluate some physiological aspects of papaya crops in semi conventional and organic production systems. The following factors assessed in this experiment were: 1. Production systems (organic and semi conventional); 2. Genotypes (Maradol and Maradona F1), and 3. Cover crop plants (Canavalia, vegetative cover and no cover). Twelve treatments were obtained -product of factors’ combination- and distributed under a threerepetition experimental design of subdivided parcels. The factors examined in this study, that changed the CO₂ assimilation rate, were production system and genotype. It was determined that the greatest gas exchange in papaya crops happened… More >

Abstract Camelina (Camelina sativa L.) is famous for its oil quality and unique fatty acid pattern. Growth and yield of crops reduced under water deficit conditions. Environmental threat such as drought or water deficit condition is the emerging problem which creates the negative impact on the growth of plants. Based upon the current situation a pot study was performed in rain out-shelter to explore the effect of different plant densities (15, 10 and 5 plants per pot) on growth and seed yield of two camelina genotypes under normal (100% WHC) and water deficit (60% WHC) conditions by using completely randomized design… More >

Abstract The objective of this work was to analyze the impact of a vermicompost treatment on anatomical and physiological modifications related to assimilate partitioning and growth in lettuce seedlings. The results showed that vermicompost increased growth, which was most likely due to an increased activity of the ground meristem of the leaf blade. A greater height and number of chlorenchyma layers were observed in the leaf blade. This was related to an increase in the photosynthetic activity, expressed by an increase in the net assimilation rate. Vermicompost also showed an effect at the procambium level, producing an increase in the number… More >

Abstract The development of three cotton varieties was evaluated through the growth analysis technique. Study varieties were two of normal leaf (Cian Precoz and NuCotton 35B) and the other of okra leaf (Fiber Max 832). Vegetative and reproductive samplings effected at different days after planting (dap) allowed us to determine the (1) growth dynamics, (2) production efficiency and (3) the biomass distribution of the three cotton varieties. Seeding was conducted following the production system of narrow rows (0.76m, between rows; 0.20m between plants) to obtain a plant density of 65500 plants/ha. Varieties were distributed in a random block experimental design with… More >
