The aim of this work was to study the effect of sub-doses of herbicide nicosulfuron on the levels of chlorophyll and growth of marandu-grass in an forest-livestock integration system. The treatments consisted of eucalyptus consortium with sorghum (BRS 655 hybrid) and forage Urochloa brizantha cv. Marandu (marandu-grass) at 12×2 and 12×3 m spacings in agroforestry systems, in addition to sorghum + marandu-grass and marandu-grass in monoculture. The doses of nicosulfuron applied at the marandu-grass were 0, 15 and 30 g ha-1. At 30 and 120 days after the application of nicosulfuron, chlorophyll a and chlorophyll b were measured usinf a portable chlorophyll meter, with six measurements per plant. Afterwards, the total chlorophyll content and chlorophyll a/b were calculated. We also measured the mass of the total dry matter of marandu-grass and growth rate of the culture. Marandu-grass plants cultivated in monoculture showed higher quantities of chlorophyll and the highest growth rates. The levels of chlorophyll a, b and chlorophyll a/b and the growth rate of marandu grass were similar between systems integrated with eucalyptus (12x2 and 12x3 m). The increase of herbicide dose negatively influenced on chlorophyll content in marandu-grass in all treatments evaluated. The use of nicosulfuron in doses of 25 and 50 g L-1 reduced the growth rate of marandu grass only when grown in monoculture

Abstract Algae are a photosynthetic organism, affordable and naturally rich in nutrients and a valuable source of bioactive substances such as natural pigments. Bulung sangu (Gracilaria sp.) is red macroalgae that wildly grows and distributes in Bali. The aim of this work was to optimize the solvent to extract the chlorophyll content of Bulung sangu. The pigment extraction was carried out using different solvents (100% methanol, 100% ethanol, and 90% acetone). The chlorophyll contents including chlorophyll a,b,c,d and total chlorophyll were measured using spectrophotometry UV-VIS and expressed in µg/g of algae. The results showed that chlorophyll c could not be extracted using all used solvent, while chlorophyll b can only be extracted using acetone. Acetone produced the highest concentration of chlorophyll a (717.52 ± 9.71 µg/g), chlorophyll b (7.23 ± 0.24 µg/g), chlorophyll d (21.93 ± 1.07 µg/g), and chlorophyll total (746.67 ± 8.99 µg/g) compared to other solvent, that were significantly different (p<0.05). The second solvent to produce the highest concentration of chlorophyll a, d, and total chlorophyll was methanol which produced 578.77 ± 9.74 µg/g, 5.50 ± 0.12 µg/g and 584.27 ± 9.62 µg/g of chlorophyll content, respectively, followed by ethanol which produced 520.98 ± 2.52 µg/g of chlorophyll a, 3.56 ± 0.25 µg/g for chlorophyll d, and 524.54 ± 2.30 µg/g for total chlorophyll. Acetone is considered the most effective solvent to extract the chlorophyll content of Bulung sangu.

Soil moisture stress in lentil (Lens culinaris L.) cultivated in rice (Oryza sativa L.) fallows of Tripura (50 m above msl), India, is one of the issues related to low productivity. Effects of foliar feeding of lentil with urea and potassium chloride KCI @ 2% each, singly or in combination either at 50% flowering, 50% podding or both at 50% flowering + 50% pod formation stages under moisture stress condition were investigated. The key physiological parameters viz. chlorophyll a, chlorophyll b, total chlorophyll content, leaf relative water content (LRWC), excised leaf water loss (ELWL) and yield attributes of lentil were measured. There were significant plessthan0.05) increases in chlorophyll a, chlorophyll b and total chlorophyll content at 50% flowering and 50% pod formation stage in plants treated either with 2% KCl alone or in combination with 2% urea as compared to those under control and 2% urea alone. Further, LRWC and ELWL were the highest (83%) and lowest (0.7%) under combined application of two agro chemicals, respectively. Significant (plessthan 0.05) increases in plant height, number of branches per plant, numbers of pods per plant and biomass as well as seed yield were also observed with combined foliar application of agrochemicals in comparison to those under control. The highest LRWC and lowest ELWL were recorded in case of foliar spray at 50% flowering + 50% pod formation as compared to either 50% flowering or 50% pod formation stage alone. Foliar application of both agro-chemicals mitigates the terminal moisture stresses especially in underutilized rice-fallow lands for successful cultivation of rabi crops like lentil.
