23 pages, Rice is susceptible to various abiotic stressors, including drought, heavy metals, salt, cold, and submergence. This research was conducted to evaluate the secondary traits of six rice varieties as indicators of drought tolerance. It was conducted from February 19 to July 6, 2024, in Paddaoan, Conner, Apayao, utilizing a factorial setup within a Randomized Complete Block Design composed of two water conditions (well-irrigated and water-stressed) applied to six varieties: PSB Rc10, NSIC Rc160, NSIC Rc506, NSIC Rc508, Mestizo 20, and Mestizo 73. This study focused on the identification of rice genotypes that are relatively higher yielding under drought condition as well as determination of the relationship between yield attributes and yield. Results showed that well-irrigated conditions significantly affected all parameters, with unstressed plants surpassing their stressed counterparts. Among the varieties, NSIC Rc160, NSIC Rc508, and Mestizo 73 shown exceptional performance in growth, fertility, and yield, especially under non-stress settings, with NSIC Rc160 achieving the highest metrics. In contrast, PSB Rc10 consistently exhibited the least favorable performance in both treatments, signifying inadequate drought adaption. Notable genotype-by-treatment interactions were recorded, underscoring varied varietal responses to drought. The research underscores the necessity of advancing drought-resistant cultivars for sustainable rice cultivation and advocates for the utilization of high-yielding genotypes in both irrigated and rainfed regions. Further study across many places and seasons is advised to validate these findings.
7 pages, The application of balanced fertilizers is essential to produce highquality broccoli. A field experiment was conducted to find an appropriate fertilizer management practice for broccoli (Brassica oleracea L. var. ‘Italica’) that can generate higher yield and quality. The experiment comprised 24 treatment combinations with six fertilizer management practices, i.e., T1: control. T2: cow dung at 10 t ha-1. T3: chicken manure at 10 t ha-1. T4: recommended NPK dose. T5: cow dung at 5 t ha-1 + 50% of the recommended NPK dose. T6: chicken manure at 5 t ha-1 + 50% of the recommended NPK dose. The highest plant height (60.00 cm) occurred in response to T6, the highest stem length (22.25 cm) in T4, and the maximum number of leaves per plant (22.00) in T4 and T6 treatments. Maximum fresh leaf weight per plant (609 g), stem diameter (3.98 cm), curd diameter (16.63 cm), and individual curd weight (494.50 g) occurred in response to the T5 treatment. The optimum yield (25.78 t ha-1) of broccoli can be obtained by application of cow dung (5 t ha-1) with a recommended dose of 50% inorganic fertilizer NPK (T5). Maximum TSS value (10.54%) occurred in response to T3, which was statistically similar to the effect of T6 (10.52%). Vitamin C content (80.77 mg 100 g-1) became significantly high in response to the T4 treatment (100% recommended dose of NPK). Minimum vitamin C content (53.84 mg 100 g-1) occurred in the control treatment (T1). Applying cow dung at 5 t ha-1 in addition to the 50% recommended dose of NPK fertilizers (T5) led to superior yield values in broccoli.
8 pages, Commercial, Industrial and agricultural wastes are major soil pollutants, which contain inorganic, organic compounds and heavy metals. When these heavy metals accumulate in agricultural lands, they adversely affect on growth and physiology of crops ultimately causing decrease in food productivity. In this experiment maize was used to investigate the effects of heavy metals on plant physiology and growth. Maize is cultivated throughout the world for its importance as cereal. It is the third most important cereal crop, following wheat and rice. Maize is a significant food source for humans providing essential minerals, vitamins, carotene and ascorbic acid. Apart from its importance as a cereal source, it also serves as important raw material for various products such as syrup, starch and oil. Various concentrations of Cr and Mn were applied individually as well as in combination to examine their effects on growth and physiology of maize. Analysis of recorded data showed that the treatment 0.5 mM MnCl2 + 0.25 mM CrCl3 had the most harmful effect and caused significant decrease in height, number of leaves and chlorophyll 'a' and 'b' in the stems and leaves. While less harmful effects were seen when heavy metals were applied individually such as 0.25 mM CrCl3, 0.25 mM MnCl2 and 0.5 mM MnCl2 as these treatments did not significantly impact on height, leaf area and chlorophyll content in stems and leaves. So, from these results it can be concluded that. when chromium was applied separately, it had minimal impact on plant physiology and growth, but in combination with manganese, it severely affected on maize plants. Similarly, a small concentration of manganese alone did not affect plant growth, but combined with chromium, it negatively impacted photosynthetic pigments and growth traits.
pgs. 11275-11284, Via online journal, The way in which farm managers' attitudes, personality, behavior, values, and sociodemographic characteristics influence farm business performance is, at best, only partially understood. The study reported here expands on this understanding by analyzing the attitudes and personal attributes of 80 dairy farmers in Great Britain in relation to the profitability over 3 yr of their farm businesses. Business goals, temperament, purchasing behavior, and having a growth mindset toward the business were found to be associated with profitability. A linear regression model consisting of 5 variables related to the above was presented that predicts 34% of the observed variation in profitability. Each of these variables were questions related to the participants' personal attitudes or beliefs. Other assessed variables, such as specific husbandry behaviors or practices, or management practices and sociodemographic characteristics, did not warrant inclusion in the final model. These results uniquely contribute to understanding how the attitudes, personality, behaviors, and attributes of dairy farmers are associated with, and thus likely to influence, the profitability of their farm businesses.
