The present investigation was conducted to determine the feed quality of New Sudan grass varieties. On average, highest plant height found in variety Nika (274 cm) 2019-2020. These rates Sputnitsa and Aleksandrina were loer by 23 30 cm, respectevely. yield green matter after two cuts new 41.0 t ha-1 9.59 hay. recognized varieties varied range 35.0-36.0 7.98-8.28 ha-1. maximum protein content fo...

A mean mechanization index of 0.59 and a total machinery energy of 477.78 MJ/ha were recorded for the direct seeding paddy cultivation in Malaysia. Highest mechanization index and machinery energy were obtained in the harvesting operation (0.99 and 336.81 MJ/ha) while the lowest values were in pesticides operations (0.19 and 3.97 MJ/ha). The benefit-cost ratios for an average farmer with and wi...

the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...

Field experiments were carried out at the Agronomy Main Research Farm, O.U.A.T. Bhubaneswar, Odisha, India during 2019 and 2020 to find energetics economics of green gram as influenced by varying land configuration nutrient management practices. Split-plot Design was adopted with three replications. Results experiment showed that raised bed method PDM-139 cultivar in combination F6 treatment ga...

In the study, mean germination time (MED) was determined as 16.6 days, 21.08 and 9.75 days in traditional sowing method, cross double row method Parallel planting respectively, rate index (ERI) same order. It found 0.31 - 0.52 0.40 pieces/m.day. Grain yield 15260 kg/ha 22330 18300 parallel method. As a result of experiments calculations, net energy to be 297,353.23 Mj/ha, 238.986.57 194.782.97 ...

The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
