Abstract

Wheat crops can grow and produce well on the island of Lombok and have opportunities for development, ranging from uplands to the lowlands about 400 m above sea level. This adaptation effort needs to be followed up with the development of cultivation technology, including proper irrigation. Watering is a fundamental factor in getting maximum yield in a cropland. This study aims to determine the exact intensity of water supply to obtain maximum grain yield. This research was conducted by experimental method in field using 3 irigation intensity on 4 varieties of grain Nias, Dewata, Gladius, and Estoc. High rainfall occurred during the experiment, so the soil was always wet throughout the experiment. Excessive rain that causes irrigation treatment does not affect the growth and yield of plants. Nias gave higher yield (2.62 t/ha) compared to Dewata varieties (1.68 t/ha), Estoc (1.41 t/ha) and Gladius (1.14 t/ha). Some growth and yield components are severely depressed due to these addictions, such as number of tillers, number of panicles and number of seeds / m2, resulting in lower yields than expected.

Abstract

This purple-pod vegetable bean has been selected until the seventh generation so it has shown a high enough uniformity, the color of the pod is more than 95% purple. The color of the purple pod is closely related to the anthocyanin content. The more purple the pod color indicates the higher the anthocyanin content. Therefore, it is necessary to test the preliminary yield abilityof several selected vegetable bean lines at two different agro-ecosystem locations ie on dry land and on paddy field to see index of sensitivity and adaptation. These hybrid vegetable beans are obtained by hybridization between cowpea species (Vigna unguiculata L. Walp.) Local varieties of NTB with long beans (Vigna sesquipedalis L. Fruwirth). The long-term goal of this research is to obtain new superior varieties of purple hybrid vegetable bean with high Protein and Anthocyanin content, tolerance to drought, without any lanjaran in the cultivation system and high production. This research activity is a series of previous research that has been done in the form of hybridization between cowpea with long bean followed by selection until the seventh generation. Ten lines have been planted for testing on dry land in Kayangan District of North Lombok Regency and rice fields in Narmada District, West Lombok regency. The observed characters were pod color, number of pods per plant, pod length, pod diameter, pod softness, fresh pod weight, number of seeds per pod, stem diameter, number of productive branches, and harvest age. The hybrid  bean number 85 (KH85) has the highest yield compared to other lines but is not significantly different from that of the hybrid bean number 51 (GKH51); 2). The genetic diversity coefficient is in the range of 7.04 to 46.30 %. The significance of heritability is 17.9 to 86.2 larger than the narrow sense of heritability ranging from 11.8 to 67.9; 3). The number of pods per plant has a significant positive correlation to the yield so that it can be used as a selection criterion to improve the yield ability

Abstract

Tujuan penelitian ini untuk mengevaluasi pengaruh penyisipan beberapa baris tanaman kacang tanah varietas Hypoma-1 di antara barisan jagung yang ditanam pada jarak tanam berbeda terhadap pertumbuhan dan komponen hasil beberapa varietas jagung. Percobaan dilaksanakan di kebun percobaan Fakultas Pertanian di Narmada, dari bulan Juni s/d Oktober 2017, yang ditata menurut rancangan Split Split Plot dengan 3 faktor perlakuan, yaitu tumpangsari (T) aditif dengan tanaman kacang tanah sebagai faktor petak utama, dengan 4 aras perlakuan (T0= jagung monokrop; T1, T2, T3= penyisipan 1, 2 atau 3 baris kacang tanah); varietas jagung (V) sebagai faktor anak petak, dengan 3 varietas (V1= jagung ketan lokal Bima, V2= populasi C2; V3= varietas hibrida Bisi-816); dan jarak tanam (J) jagung antar baris sebagai anak anak-petak, dengan 3 aras perlakuan (60, 75 atau 90 cm), sehingga terdapat 36 kombinasi perlakuan yang masing-masing dibuat dalam 3 blok (ulangan). Hasil penelitian menunjukkan bahwa ada pengaruh interaksi tiga faktor terhadap bobot tongkol per ha dan variabel pengamatan lainnya, kecuali tinggi tanaman dan lingkar batang saat panen sampel tanaman pada akhir fase pengisian biji, sedangkan interaksi dua faktor hanya signifikan terhadap jumlah daun per ha, yaitu antara varietas jagung dan jarak tanam. Masing-masing faktor perlakuan secara mandiri (main effect) juga berpengaruh terhadap komponen hasil tanaman jagung. Peningkatan jumlah baris tanaman kacang tanah yang ditanam-sisip di antara barisan jagung mampu meningkatkan bobot tongkol per ha dibandingkan dengan tanpa penyisipan tanaman kacang tanah. Jarak tanam juga berpengaruh terhadap semua variabel pengamatan, terutama komponen hasil; secara per individu tanaman, bobot tongkol tertinggi pada jarak tanam 90x20 cm sedangkan bobot tongkol per ha tertinggi pada jarak tanam tersempit (60x20 cm), yang berarti bahwa peningkatan kerapatan tanaman masih bisa dilakukan dalam upaya meningkatkan produktivitas tanaman jagung terutama yang disisipi tanaman kacang tanah, yaitu varietas Hypoma-1.

Abstract

Seed germination tends to be low due to seed viability reduction, especially on new crops developed, such as Moringa, so the understanding of seed  and seedling characteristics should be given attention. This objective the research is to evaluate Moringa seed morpho-physiology and seedling agronomical characteristics from North Lombok. The results showed that, moringa seed morphological characteristics of North Lombok accesions did not vary in seed length and wide. The variation was only on 1000 seed-weight. The weight ranged from 167.47±9.87 g to 285.73±9.64 g. Seedling physiological character was not different in seed germination rate, but in power of seed germination. The seed germination ranged from 71.50 to 82.50%. In seedling agronomical characteristics, however,  showed different in fresh and dry shoot weights at one month old, shoot dry weight, root fresh and dry weight at two month old. The heaviest shoot dry weight was been shown by accsesion Bayan 1 dan 3, and the heaviest root fresh and dry weight were shown by the accesions of Kayangan 2, Bayan 3, and Pemenang 1.
