Chlorophyll, crop growth rate and forage yield of Brachiaria (Brachiaria brizantha Stapf) as the result of goat manure in various nitrogen dosage

Abstract

Abstract. The research was done to find out theeffect of manure and N dosage on chlorophyll content, plant height, crop growth rate (CGR), forage yield, dry matter ((DM) yield and DM content of BrachiariabrizanthaStapf. The experiment used manure (0 and 5 ton/ha) and nitrogen dosage (50, 100, 150 kg N ha -1 ) set in factorial design 2 x 3, repeated three times. The result showed that manure increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. N dosage increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. The interaction between manure and N dosage increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content. The result showed that manure usage and nitrogen dosage 150 kg N ha -1 increased chlorophyll content, plant height, CGR, forage yield, DM yield and DM content in the amount of 27.5; 20.5; 98.4; 68.5; 103.4 and 20.5% compared to without manure and nitrogen dosage in the amount of 150 kg N ha -1 .

Assessment of Soil Chemical Properties for Monitoring and Maintenance of Soil Fertility in Probolinggo, Indonesia

“…The non-existent high N-total value corroborates another soil analysis on several agricultural lands in West Java [56] and adds urgency to the call for management to enhance nitrogen content in agricultural fields throughout Java recommended by a previous study [26,75]. An essential nutrient for plants [24,76], nitrogen determines plant growth [32,77] and therefore significantly influential towards harvest. Nitrogen is assimilated by the plant into amino acid, the main component of protein [78] that is responsible for forming chloroplast, mitochondria, and other structures where biochemical processes in plants occur.…”

“…The fact that tropical lands naturally contain less nitrogen has been proven by contrasting Java with Japan [75] since higher temperature accelerates organic matter decomposition [2,28]. Improper use of pesticides in agricultural practice not only eradicates nitrogengenerating bacteria [21,83] but also restrains the work of enzymes in the nitrogen cycle [23,24].…”

“…Another cause is low irrigation water quality [19,20]. Pesticides are also liable for affecting microorganisms [21,22], particularly in enzymes entailing carbon, nitrogen, sulphur, and phosphor cycles [23,24] While fertilizers may be helpful, excessive use of chemical fertilizers reduce soil biodiversity and function [25,26] by triggering soil acidification and soil crusting that suppress the growth of organic matters [2, 27,28].…”

​The Growth Response of Banana cv. Barangan (Musa acuminata L.) from Tissue Culture with Organic Manure and Arbuscular Mycorrhizal Fungi

“…Table 3 shows that the goat manure application to the planting media results in a higher pseudo-stem diameter due to the chemical composition of the goat manure itself (Sebetha and Mashele, 2019). The high nitrogen content in goat manure forms nucleic acids, amino acids, proteins and cell enlargement so that the diameter of the stem increases (Purbajanti et al, 2016). The lowest pseudo-stem diameter is seen in the compost application.…”

Effect and Effectivity of Granular Organic Fertilizer on Growth and Yield of Lowland Rice

“…Organic fertilizers are sustained sources of nutrients due to slow release during decomposition [4]. Therefore, the use of organic fertilizer is encouraged to overcome these problems [5] Organic fertilizer is fertilizer derived from dead plants, animal dung or animal parts, and other organic waste. It has been through an engineering process and can be enriched with minerals and microbes.…”
