“…Also. This is in line with(9,11) effect of harvest time on grain yield was significant, and with(21,28) different grain yield according to different harvest dates. CONCLUSIONS It can be concluded that grain number per panicle and weight of 1000-grain are among the most influential traits to yield determining, and grain harvest before harvest date (14 days after physiological maturity) reduces grain yield due to high moisture content of grain, especially when harvest at stage of physiological maturity, and delaying harvest after harvest date (14 days after physiological maturity) reduces seed vigor and yield due to low grain weight and loosening of grain, especially at harvest after 28 days after physiological maturity.…”

A field experiment was carried out at Rice Researches Station in Mashkhab, Najaf in 2020 and 2021 seasons to study the effect of cultivars and harvest date on some traits of rice yield. Randomized complete block design was applied within split-plot with four replications. Five cultivars of rice (Amber 33, Yasmin, Dijlah, Amber-albaraka and Furat 1) were distributed in the main plots and five harvest dates (harvest at physiological maturity and harvest after 7, 14, 21 and 28 days of physiological maturity) in the sub-plots. The results showed significant difference among cultivars, and superiority cultivars of Dijlah, Furat 1 and Yasmin in recording the highest yield due to its superiority in number of grains per panicle or weight of grain. It can be concluded that traits of grain number in panicle and weight of 1000-grain were among the most influential traits in determining the grain yield, and date of harvest plays an active role in determining the traits of yield. Third harvest date was the best in grain yield, and early harvest before that date would cause loss of yield for all cultivars due to the high grain moisture, and delay after that date would cause a loss of yield as a result of shattering ratio of grain, in addition to difference of cultivars in recording shattering ratio according to harvest date. It can be recommended planting cultivars of Dijlah, Furat 1 and Yasmin, as they achieved the highest yield, and considering the harvest date 14 days after physiological maturity the best date to obtain the highest grain yield.

“…If the grain of paddies is collected when the grain of paddies has not mature, a grain of paddies easily decays. Yehia & Khatab (2017) reported that too early or too late harvesting of rice results in more broken milled rice. The quality also depends on the rate of liquid content in grain of paddies, the community vanish the liquid of paddies grain naturally, they hang paddies panicle which has been bound and hang it in lantayan (traditional hanging equipment for paddies).…”

Climate change is characterized by several elements, namely unpredictable rainy and dry seasons, floods and unpredictable droughts. This study aims to determine the indigenous peoples’ local wisdom in adapting to climate change, which includes screening process of local paddy seeds, the use of organic fertilizers, and traditional harvest management strategies. The method used in this research is the qualitative research method combined with the ethnographic approach. This method is applied based on the consideration that the topic of this research is related to the culture and social of indigenous peoples. The data was collected by means of in-depth interviews, observation, and documentation. Informants were selected by using the purposive sampling technique. The results were scrutinized carefully by means of the triangulation process. The results of the study show the facts that the way indigenous peoples deal with climate change is by physically and physiologically selecting seeds and storing seeds for three months so that the seeds will grow stronger. In addition, they only selects paddies that has reached a full state of growth, that is mature to avoid going rotten even though the climate change occurs. Then, they have the traditional rice dryers to get rice dried, thereby enabling those to be more climate-resistant. They also use the organic fertilizer to reduce the production of emissions as a cause of global climate change. Perubahan iklim dapat diamati mulai dari musim penghujan dan musim kering yang tidak menentu, bencana banjir, dan kekeringan yang sulit untuk diprediksi. Penelitian ini bertujuan untuk mengetahui kearifan lokal pada masyarakat adat dalam beradaptasi terhadap perubahan iklim mulai dari seleksi benih padi lokal, penggunaan pupuk organik, dan manajemen panen secara tradisional. Metode yang digunakan adalah kualitatif dengan pendekatan etnografi. Metode ini diterapkan karena penelitian berkaitan dengan budaya dan sosial masyarakat adat. Pengumpulan data dilakukan melalui wawancara mendalam, observasi, dan dokumentasi. Pemilihan informan menggunakan teknik purposive sampling. Kemudian, hasil pengumpulan data diteliti dengan cermat melalui triangulasi. Hasil penelitian menunjukkan bahwa masyarakat adat mengatasi perubahan iklim dengan melakukan seleksi benih secara fisik dan fisiologi dan menyimpan benih sampai dengan 3 bulan agar benih kuat dalam pertumbuhannya. Disamping itu, petani adat harus memanen padi matang sehingga padi tidak mengalami pembusukan meskipun terjadi perubahan iklim. Kemudian, masyarakat menggunakan mengelola hasil panen dengan alat pengering padi tradisional sehingga hasil panen padi lebih tahan iklim. Setelah itu, masyarakat adat menggunakan pupuk organik sebagai cara untuk memperkecil produksi emisi sebagai penyebab perubahan iklim secara global.
